Context

On Tuesday 20 November 2018, the European Parliament and the Council agreed on new rules enabling access to the EU single market for fertilisers made from organic or recycled materials. The agreement represents a success of long negotiations on rules on fertilisers, already started in 2016, when the Commission announced a legislative proposal on fertilizing products, in line with the circular economy plan, including reasonable limits for contaminants, especially for cadmium. The agreement needs to be confirmed by the EU Member States ambassadors and the European Internal Market Committee IMCO. Then it will be put to a vote by the Parliament in plenary session and formally approved by the EU Council of Minister. In any case, the new deal provisionally agreed marks a significant overcoming of the EU current rules as it includes all types of fertilisers (mineral, organic, soil improvers, growing matters, etc.) and it is aimed at: promoting an increased use of recycled materials for producing fertilisers, for supporting the development of circular economy and reducing dependence on imported nutrients; making it easier the market access for innovative, organic fertilisers, giving farmers and consumers a wider choice and promoting green innovation; establishing EU-wide quality, safety and environmental criteria for “EU” fertilisers (i.e. those which can be traded in the whole EU single market).

However, agriculture and food industry having a high dependence on resources in their production and striving for long-term sustainability. In this context there is an urgent need to optimise resource use and smooth the transition to a knowledgedriven agriculture.

Objectives

The project objective is to improve the exploitation of the N/P nutrient management/recovery potential for the ready for practice cases not sufficiently known by practitioners. The objective is to make a collection aimed at obtaining an overall picture of the most innovative technologies and the fertilizers produced from un-exploited resources of organic or secondary raw materials in line with the circular economy model, in order to give farmers environmental/economical sustainable guidelines. Effective dissemination and exploitation will be promoted by multilingual web platform, other communications and best practice field demonstrations for farmers.

Objectives

Activities

The main project activity is the specific collection and provision of practice-oriented knowledge for Nitrogen and Phosphorus recovery innovative TECHNOLOGIES and PRODUCTS ready for practice, which is providing inventory and resulting strategies for priorities. The outputs will be the basis to ~100 practice abstracts written in the common EIP-AGRI format and training materials. Practice abstracts and training materials will be used for the interactive dissemination of the best practice interactive demonstration and for online dissemination programmes.

Activities

The NUTRIMAN work plan consisting of seven coherently integrated work packages. WP1 sets out the 'ethics requirements'. The basic project platform is the specific collection and provision of practice-oriented knowledge for Nitrogen and Phosphorus recovery innovative TECHNOLOGIES and PRODUCTS ready for practice (WP2). WP3 will provide practice abstracts in the common EIP-AGRI format and training materials. The WP3 practice abstracts and training materials will be utilized in WP4 interactive dissemination best practice interactive demonstration and WP5 online dissemination programmes that are promoted by WP6 communication programmes.

Additional information

NUTRIMAN is an EU-funded project that compiles knowledge of “ready-for-practice” recovered bio-based fertiliser product applications, practices and technologies, for the interest and benefit of agricultural practitioners. Agriculture practices strongly depend on the availability of resources, such as energy, water and nutrients, in order to ensure their long-term sustainability. Of the 176 million hectares of arable land in the EU, 76% is fertilised. European farmers rely on the continuous supply of mined, non-renewable phosphorus and energy-intensive nitrogen. Yet, the use of mineral fertilisers has resulted in a depletion of resources and pollution of the environment. Consequently, there is an urgent need to improve the availability and efficient use of nitrogen and phosphorus. To achieve this, the implementation of commercial nutrient management and recovery methods are of key importance for the sustainability and circularity of the EU agriculture industry.

This auto-thermal 3R zero emission pyrolysis and phosphorus recovery technology has been specifically developed and designed for added value valorisation of food grade animal bone byproducts into high value recovered Phosphorous fertilizer by integrated thermal and biotech recycling means. The Animal Bone Char Bio-Phosphate product is made of different types of food grade animal bone grist, most importantly cattle bones, which mono feed input is already pre processed at 133°C, 3 bar for 20 minutes. The bio-based apatite based cattle bone grist input feed is low value by-product and unexploited biomass. In the 3R process the bone grist is continuously processed at a material core carbonization temperature as high as 850°C, which is far higher than usual biochar processing temperatures, but absolute needed to get high quality product, which is formulated to BIO-NPK-C bio-fertiliser. Zero emission means that all material streams in all forms are recycled-reused and converted into useful products. During the advanced 3R pyrolysis (reductive thermal processing) all volatile and protein based substances are removed from the biobased apatite mineral frame, and a highly macro-porous hydroxyapatite (70-76%), CaCO₃ (7-13%) and carbon (8-11%) contained mineral products were produced. This innovative technology is successfully high TRL proven through field demonstration in industrial operational environment, market launch 2021.The standard 3R industrial productivity is 20,800 t/y throughput capacity/unit, resulting 12,500 t/y BioPhosphate product for organic farming and adsorbent applications, and surplus 2 MWe/hour green electricity.

The Detricon stripping/scrubbing process recovers ammonia from the liquid fraction of manure, digestate or other liquid waste streams with more than 0.1% ammonia nitrogen. The technology produces a technical pure-end product, ammonium nitrate, which can be used to enhance the growth of corn, grass, vegetables in conventional farming. Stripping/scrubbing by Detricon is energy efficient and economic interesting technology to produce a pure nitrogen fertilizer locally without other nutrients. It is an example of circular economy. The produced liquid ammonium nitrate has a ratio of 50/50 ammonia and nitrate. The N-P-K (%) ratio is 18-0-0 or 10-0-0. This pure technical product is odourless and colourless and suitable for replacing mineral fertilizer in agriculture. Ammonium nitrate from Detricon technology can be used in open field crops or greenhouse crops, such as corn, grass, vegetables, with an application dose of 0.5-1 t/ha. Special attention goes to the foliar application: spraying can give leaf damage. Therefore it is recommended to inject it directly into the soil. The price varies between 0.65-0.75 euro/kg N.

Through the AMFER® stripping technology, Ammonia is recovered from liquid and washed by acid to produce an ammonium salt like ammonium nitrate or ammonium sulphate. The most used input materials are digestate from manure digestion and co-digestion. But also waste water streams with high nitrogen levels can be treated in the AMFER®. The system is operated as a batch process or as a semi-continuous process. Both can meet the requirements for animal by-products. Therefore raw digestate can be treated in the AMFER® before solid/liquid separation. The remaining is a liquid fraction low in N and P and a pasteurized solid fraction rich in P. Fertilizer products from the AMFER® have high nitrogen content, e.g. Ammonium nitrate (52%) has a nitrogen content at 18% and Ammonium sulphate (35%) at 7%. These recovered nitrogen products are expected to be listed as ‘mineral fertilizer’ from 2021 for the whole EU. That means those nitrogen products can be applied in the 250 kg N/ha space. The recommended application doses are crop and soil depending. On a farm level, this reduces the fertilizer purchase to a minimum. Depending on local situation, these fertilizers can be applied in any farming systems (conventional, organic, etc.) with nitrogen demanding crops, or Nitrogen and Sulphur demanding crops. Application of the fertilizer is identical to liquid nitrogen fertilizers from the major fertilizer companies.

The BENAS biogas plant uses a modified stripping process to recover the ammonium nitrogen from digestates. By adding a cheap FGD gypsum, it produces a concentrated marketable ammonium sulphate solution (25% AmS) and a solid calcium carbonate fertilizer (Lime, 70% DM). The BENAS process recovers 67% of NH₄-N as AmS and 6% of NH₄-N as Lime. It also reduces the greenhouse gas emissions by lowering CO₂ emissions from digestate transportation and reduce ammonia, nitrate and nitrous oxide emissions. The produced AmS solution can be used for producing mineral fertilizer solutions or for upgrading manure or digestate low in N content. It benefits as its neutral pH is well tolerated by plants. The concentration of 25% AmS avoids evaporative crystallization, making it a suitable for direct application on crops. This product can be applied to all crops in need of nitrogen and especially those sulphur demanded. The recommended dosage will depend more on the sulphur requirements of crops. In order to reduce the risk of emission during application, it is recommended to apply the AmS solution via injection or immediately incorporated into soil after surface application.

The hygienised remains of biogas production – digestate – contain the resilient organic fraction, water, and micro- and macro-nutrients from the digested (pig) manure and other organic (waste) streams. Washing the exhaust air, from the digestate-drying process, with sulphuric acid leads to the by-product: drainage water or an ammonia sulphate solution considered a mineral NS fertiliser. The solution produced at Biogas Bree (B) contains around 8 % N and 25% SO₄. This allows the ammonia sulphate solution to perfectly meet the nitrogen and especially sulphur requirements of crops (e.g. cabbage crops, onions, celery, leeks, cereals, sugar beets, maize, etc.). The pH of the ammonia sulphate is 4 to 5.5 depending on the adjustment of the acid scrubber. Contents of pH, nitrogen or sulphur can be further optimalised by mixing with e.g. urea (classic liquid nitrogen fertilizer). Based on soil analysis results (N & S), the crop requirement and the soil type, etc. the correct dosage should be calculated. Commonly however the dosage often fluctuates around 1m³ per hectare. In order to make optimum use of its effect as a fertiliser, it is desirable to make the product very specifically available to the plant, either at the start of cultivation or in the form of additional fertilisation. In order to avoid the risk of burning during the administration of ammonium sulphate, especially in windy and sunny weather new specific application techniques are used (cfr UNIR project) such as draghose or spoked wheel fertilization. The Biogas Bree commodity is locally priced at around 10€/m³ or around 10€/ha.

NH₃ emission from the pig stables is recovered by on-farm scrubbing with sulphuric acid. This process reduces the GHG emission from pig farm and contributes to a more sustainable agriculture. The resulted ammonium sulphate is a brown-colored liquid with a pH at 4.6-6.1, depending on the adjustment of the acid scrubber. The product usually contains 41 g/kg of N in the form of NH₄-N, which is supposed to be 100% directly available for plants. Due to the highly concentrated N in ammonium sulphate, compared to animal manure, lower amount is needed for agricultural application. In addition, the ammonium sulphate also contains around 100 g/L SO₄²- providing 30 g/kg of sulphur (S). This allows the product to perfectly meet the nitrogen and especially sulphur requirements of crops. Therefore, this ammonium sulphate can be applied as a liquid fertiliser to substitute synthetic fertilisers. This product is recommended to be applied at 1- 1.5 ton/ha, the correct dosage should be calculated based on soil nutrients status and the crop requirement. In order to reduce the risk of emission during application, it is recommended to apply the ammonium sulphate solution via injection or immediately incorporated into soil after surface application. The price of the product would be 10 €/Ton without transport collected at the farm.

Ammonium sulphate is produced with the VP-Hobe Manure Valorisation system, using flotation, belt press sieve, reverse osmosis, evaporator and stripper technology. The input is pig manure or digestate. The ammonia in the incoming liquid is removed from the product flow by stripping and scrubbing the vapour coming out of the evaporator with sulphuric acid into ammonium sulphate (7% N).
Key product features:
• Liquid nitrogen fertilizer
• N (NH₄): 70 g/kg
• P₂O₅: 0 g/kg
• K₂O: 0 g/kg
• S: 76 g/kg
• Potential RENURE fertilizer
• Natural product
• Low in phosphate
• Free from salmonella and E-coli
The production and usage of RENURE fertilizers allows farmers to process their (excess) livestock manure into a RENURE fertilizer. This product is a potential RENURE fertilizer which means that application will no longer be defined as livestock manure in the Nitrates Directive. This means application will no longer be limited to 170 kg N/ha.
Because the N an K are separated in two fractions optimal N/K balance can be achieved using precision fertilizing techniques using biobased fertilizers.
Costs for farmers will be approximately €0 per ton ex works.
Application can be done using liquid manure injection systems. Low emission application techniques are compulsory to prevent ammonia volatilization.

The output of the Poul-AR® is a substrate with acceptable N-levels to use in a thermophilic CSTR. The other main product-output is a N-fertilizer: the stripped ammonia from fresh poultry manure is washed with a sulfuric acid leading to ammonium sulphate, or with a nitric acid, leading to ammonium nitrate. This resulting liquid and transparent scrubber water is a highly efficient nitrogen fertilizer with a 9% nitrogen (d.m.) content. This product is comparable to commercial available artifical fertilisers and has an average wholesale costprice of € 100/tonne. The N-fertiliser has been tested over last years through universities and farmer organisations mainly in the Netherlands, but also in other EU countries (Belgium, Spain and Italy): current TRL 7 expected to be TRL 9 from 2020 onwards. The product can be put together in the same concentrations as the commodity fertilizers. This opens a broad market, as existing machinery can be used to spread these fertilizers. Ammonium sulphate and ammonium nitrate are good fertilizers particularly for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. Ammonium nitrate is an important fertilizer because it contains both cation (NH₄⁺) and anion (NO₃-) nitrogen. The amounts of the product to be applied and application technology depend on product characteristics, the crop needs (N and S) season and soil characteristics.

The ash under the fireplace is generated in larger amounts and concentrates the non-combustible minerals of the wood (1 to 2% of the initial mass of the wood).
With significant levels of lime, magnesium, potassium and phosphorus, this fraction generated up to 95% of the total ash production presents valuable agronomic advantages.
A return to the ground allows benefits from the fertilizing and amending value of these ashes. They generally contain phosphorus contents around 20 to 50 g P₂O₅/kg of raw material, and potassium around 80 to 100 g K₂O/kg.
It is estimated that a soil application of 2.5 t/ha every 3 years is generally enough for soil maintenance, but this dose should be considered according to the culture system needs and the soil pH.
Cationic macro elements Ca, K and Mg in ash are readily available to potentially available for cultivation.
With a neutralizing value sometimes reaching more than 50%, ashes are a liming material that can increase the pH by 1 point after a cumulative application of 7 to 8 t/ha.
The potential risks associated with this use of ash are due to the presence of metal trace elements (MTE), at higher or lower concentrations, depending on the origin of the wood and the combustion technic. To limit these risks: choose ashes from natural wood (unadjusted) and from unpolluted media.
Under these conditions, wood ash represents a substantial saving for the farmer, from 100 to 150€/t.

EasyMining recovers P from incinerated sewage sludge ashes. With the Ash2Phos technology, a clean precipitated calcium phosphate (PCP) can be recovered from sewage sludge.. The process consists of 3 sequential steps: a first acidic step, a second alkaline step (where intermediate products are produced), and finally a conversion step where the intermediates are processed into final products. More than 90% of P in the ash is recovered.
The main output product is calcium phosphate, a white powder or granule phosphorus-calcium rich product (Ca5(PO4)3OH, 17% P, 35% Ca) with a very low content of heavy metals (Cd < 0.1 mg/kg). The water solubility is low, but P is highly available as demonstrated by the high solubility in neutral ammonium citrate. It is already proven that phosphate is slowly released, the fertilizing efficiency is therefore high. It can be applied as such on the field (as root placed fertilizer or spread as granules with common equipment), or transformed to other phosphate fertilizers (MCP, DCP, MAP, DAP, etc). In addition, PCP can also be used for animal feed, compound feed and mineral feed. In 2023, 13,000 t/a PCP (from 30,000 t ash) will be produced. The price is matter of market and negotiation.
Heavy metal and Fluor concentrations are lower than in conventional P fertilizers (Cd < 0.1 mg/kg). Therefore, it can be used for field application and in feed products. The P recovery process is independent from ash quality fluctuations (so no limitations regarding precipitation metals like Fe) and comes with highly efficient heavy metal separation to guarantee high P product quality.

In addition, PCP can also be used for animal feed, compound feed and mineral feed. In 2023, 13,000 t/a PCP (from 30,000 t ash) will be produced. The price is matter of market and negotiation.
Heavy metal and Fluor concentrations are lower than in conventional P fertilizers (Cd < 0.1 mg/kg). Therefore, it can be used for field application and in feed products. The P recovery process is independent from ash quality fluctuations (so no limitations regarding precipitation metals like Fe) and comes with highly efficient heavy metal separation to guarantee high P product quality.

AshDec® is a thermochemical process designed to convert low plant available phosphorus in sewage sludge ash to the highly plant available Rhenania-P (CaNaPO₄) while reducing the heavy metal content. Within the process, the ash is mixed with sodium compounds. Sodium ions replace calcium ions in the phosphates and form the plant available compound. A noticeable high amount of heavy metals evaporates in their elemental form at the prevalent temperatures.
The output material is calcined ash with 15-25 % P₂O₅, depending on the composition of the input material. It is a sandy material, which is milled and pelletized/granulated before application. The Pcompounds are not soluble in water, reducing environmental risks like runoff, leaching and fixation. However, the solubility in neutral ammonium citrate is > 80 %. Hence, P is released in the presence of crop root exudates, which means a P-supply on demand. The fertilizer performance tested in several pot and field trails is comparable to Triple-Superphosphate. The product has a low content of contaminants, e.g. heavy metals. It has no organic compounds and is free of pathogens. It could be used in conventional farming (vegetable, greenhouse, arable, fruit, ornamental) referred to national regulations or to the European Fertilizer Product Regulation EU 2019/1009 as PFC1 (C) “Inorganic Fertilizer”. The usage in organic farming could also be possible in future. There is a recommendation to authorize recovered fertilizers (e.g. biomass ashes) for organic farming by STRUBIAS workgroup. The dosage depends on the P-nutrient needs of the crop and the P-nutrient status of the soil. The process is not commercial yet.

VFG-compost from intermunicipal IOK's pre-fermentation + composting is a stabilised and hygienised soil improver (25,000 t/year). This compost closes the material cycle: VFG waste – vegetable, food and garden waste (including animal based kitchen waste) – is transformed into a carbon and nutrient-rich soil improver which can replenish the farmers’ soils. The IOK process and end product is unique because it increases soil fertility in times of decreasing organic carbon levels in agricultural parcels and because the process also recovers energy: biogas in cogeneration and biomethane in the natural gas grid. The footprint of this VFG compost is therefore - in accordance with Vlaco's CO₂ tool - negative. IOK's VFG compost has the Vlaco quality label (strictest requirements in the EU) and contains on average 22% organic carbon (d.m.) and various nutrients: 2% N (d.m.), 1% P₂O₅ (d.m.), 1.45% K₂O (d.m.), CaO, etc. The compost is free of pathogens and weed seeds, and is sieved and inspected on visual contaminants. VFG compost is therefore a multi-nutrient soil improver with slow-acting fertilisation (N & P) – in the long term max 40% for N - which also prevents nutrient leaching. The price is usually 2 to 12€/tonne. In order to support the soil organic matter without exceeding the phosphorus standards, an average of 10 to 15 tonnes of VFG compost/ha can be applied annually in the Flemish context, as a guideline - thereby covering part of the N-fertilisation. Compost equally increases water retention capacity and thereby decreases vulnerability to erosion and droughts.

The digestate is a solid-liquid by-product obtained from the co-digestion (anaerobic digestion) of pig manure and residues from the pretreatment process (RPP) and by-products from the refining process (BRP) of the vegetable oils.
It can benefit with the diversification of market by new environmental friendly bio-product, increased soil microbial biomass size and activity were increased under application of digestate, greater efficiency and reduced costs of managing livestock waste.
The general appearance of the product is powder or little solid particles with a NPK rate of 0.09-0.2-0. The composition of the digestate depends on the characteristics of the waste used for anaerobic digestion ([Ntotal]=600-900 mg/L, [TP]=75-240 mg/L). Digestated showed a stimulant effect on plant growth, with higher yields of barley and ryegrass in treated soils than in the control soil when digestates were applied at appropriate rate.
The digestates generated in the AD process, were tested in germination and microcosm experiments to determine their biofertilizer and biostimulant effects on plants and soils. The metals are below the limits of its classification.
The conditions of application should be similar to traditional synthetic fertilizers in liquid form. In conventional farming it is recommended permanent grasslands, cereals for the production of grain, root crops and plants harvested green from arable land by area with a dosage of 80-40 m³/ha.

Green compost from intermunicipal IMOG is a stabilised and hygienised soil improver (12,000 t/year). This compost closes the material cycle: green waste (degradable organic waste from parks, garden, public domain, roadside cuttings) is transformed and ultimately return carbon and nutrients to the farmer. The IMOG composting process and end product are unique because of its use of membranes, forced aeration and fine sieving, resulting in matured, quality compost with good moist balance. Using compost helps to increase soil fertility in times of decreasing organic matter-levels in agricultural parcels. The footprint (carbon footprint - ISO14067) of this compost is therefore - in accordance with Vlaco's CO₂ tool - negative. IMOG's green compost has the Vlaco quality label (strictest requirements in the EU) and contains on average 19% OC (d.m.) and various nutrients: 1.4% N (d.m.) - 0.5% P₂O₅ (d.m.) - 1.1% K₂O, CaO, etc. In the Flemish manure legislation, green compost is classified as a slow- acting fertiliser with max 40% slow-released N - which also prevents nutrient leaching. In order to stimulate soil improvement quality, an exemption of 50% of the phosphorus content is allowed in the calculation of the maximum amount of compost to be applied on agricultural land (in Belgium). The price is usually 2 to 12€/tonne. In order to support the soil organic matter without exceeding the phosphorus standards, an average of 20 to 25 tonnes/ha of green compost can be applied annually in the Flemish context, as a guideline, also covering part of the N-fertilisation. Compost equally increases water retention capacity and thereby decreases vulnerability to erosion and droughts.For more information: https://nutriman.net/farmer-platform/product/id_280

The NPirriK-dried digestate from Arbio (B) has an animal manure status, is free of pathogens, insect larvae and weed seeds, and can be pelleted to result in an easy to distribute fertiliser-pellet with a much higher density (700 kg/m³ instead of 350 kg/m³). Due to its high OC content the pellets from it furthermore have excellent soil improving capacities protecting soils against droughts. Most importantly it has, compared to a regular dried digestate, an optimised (higher) N/P-content - 5,5% N (TN) of which 50% mineral N -, and 2.8% P₂O₅. Dried digestate (pellets) can be categorized as PFC 1 A (solid organic fertiliser) or PFC 3 A (organic soil improver)(or in blend). Furthermore products with Vlaco-certificate should be eligible to be categorised as Component Material Category (CMC) 5. At the end of 2019 the full industrial scale of the NPirriK post-treatment flow can realise about 1500 tonnes/y of the high N/P-pellets. The market price for the pellets is estimated to rise due the optimised post- treatment add-on from 25€/ton to 45€/ton. The second RO-stream - water - can under certain conditions be either discharged into surface water, used as process water or, in case of drought, be used to irrigate nearby agricultural plots. The dried digestate is to be used depending on crop needs (vegetables, grapes, grasslands, permanent crops,..), season and soil characteristics with an average of 4 t/ha.

Furthermore products with Vlaco-certificate should be eligible to be categorised as Component Material Category (CMC) 5. At the end of 2019 the full industrial scale of the NPirriK post-treatment flow can realise about 1500 tonnes/y of the high N/P-pellets. The market price for the pellets is estimated to rise due the optimised post- treatment add-on from 25€/ton to 45€/ton. The second RO-stream - water - can under certain conditions be either discharged into surface water, used as process water or, in case of drought, be used to irrigate nearby agricultural plots. The dried digestate is to be used depending on crop needs (vegetables, grapes, grasslands, permanent crops,..), season and soil characteristics with an average of 4 t/ha.

Increased temperature and pH combined with acidic washing in stripping and scrubbing process allows for nearly all (85%) of the mineral nitrogen coming out from the slurry into a liquid mineral fertiliser as ammonium sulphate or ammonium nitrate liquid. This is a pure, high quality fertiliser without organic matter-content, prone to precision fertilising. The ammonium nitrate and ammonium sulphate produced through the Circular Values-technology are high quality fertilizers with 100% nutrient replacement value (NRV) - so no artificial fertilizer is needed. The ammonium sulphate (>7% N) and ammonium nitrate (up to 18% N) are high quality fertilisers which can completely offset the need for another/artificial fertiliser. Ammonium sulphate and ammonium nitrate are good fertilizers particularly apt for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. Ammonium nitrate is an important fertilizer because it contains both cation (NH₄⁺) and anion (NO₃-) nitrogen. The amounts of the product to be applied and application technology depend on product characteristics, the crop needs (N and S) season and soil characteristics.

Compared to the initial feedstock the digestate is homogenised, mostly hygienised, and has a higher nutrient replacement value due to a parcial transfer of the organically bound N to ammoniuml nitrogen. Given separate treatment lines at Agrogas (B) the digestate can be supplied as an animal manure-status or a non-animal manure-status. Agrogas further differentiates digestate by separating, and drying - reducing volume and transport cost per ton NPK and organic carbon and increasing product shelf life. The liquid fraction of the digestate is a dark and thick liquid-like fertiliser with particularly NK-levels of respectively up to 9.9% N and 8.9% K₂O (of dry matter by weight). The dried digestate (dry matter 80-90%) is a dry, dark, coagulated or powdery end product that has fertilising and soil improving qualities, with NPK-levels of respectively up to 3.1% N, 5.5% P₂O₅ and 4.2% K₂O (dm) as well as around 40% organic carbon (dm). Other macro-elements (MgO, SO₃, CaO) are equally present. Application doses vary around 30 t/ha for liquid fraction and 2t/ha for dried solid fraction digestate, depend on country, region, soil, season and crop. In the new Fertiliser Regulation dried digestate can be categorized as PFC 1A (solid organic fertiliser) or PFC 3A (organic soil improver) (or in blend). Both liquid and dried digestate fractions are compliant with strict requirements (ARC (Flanders) and/or Fertiliser (EU)) as to organic and inorganic/physical contaminants. Digestates have low prices of per ton nutrient, partly depending on NPK-content and the animal manure status, with highest prices for dried digestate ranging up to 35-40 €/ton (dry matter percentage >85%).

Algal biomass as a new bio-fertiliser contains macronutrients and micronutrients, some growth regulators, polyamines, natural enzymes carbohydrates, proteins and vitamins implemented for improving vegetative growth and yield. It can improve soil characteristics that have favourable effect on nutritional status of plants. Microalgal fertilisers improve the fruit quality through an increase in sugar and carotenoid content. Some studies had demonstrated that the performance of algal materials was similar to that of a conventional synthetic fertiliser or even higher.
Wastewater-grown algal materials effectively provide plant nutrients to crops and can be used successfully as fertilisers. As a biologically based (bio based) alternative, algae fertilisers could supplant some of the dependency on conventional fertilisers, reducing the need for their costly production, including principally the nitrogen fixing, phosphate solubilising and plant growth-promoting microorganisms.
An average composition for microalgae is 40-60% proteins, 10-30% lipids and 20-40% carbohydrates. This composition makes it adequate as raw material for the production of feed products and fertiliser. They allow for the recovery of the N and P present in wastewaters by concentrating these nutrients in algal biomass and have the potential to prevent nutrient losses through a gradual release of N, P and K.
For good practice or organic agriculture, the product can be applied overall in cereals for production of grain and fresh vegetables.

Mineral concentrate is produced using the VP-Hobe Manure Valorisation system. The input pig manure or digestate is first separated into a solid and a liquid fraction. Separation takes place in a flotation unit and in a belt press sieve. A reverse osmosis unit processes the liquid fraction (1.7% D.M.) into a retentate concentrated-N/K₂O product (3.4% D.M.) and a permeate product to be processed in the clean water production.

The Mineral Concentrate is a liquid fertilizer with 3.4% dry matter, 0.8%N and 0.9% K₂O. This product is a pilot RENURE fertilizer which means that application will no longer be defined as livestock manure in the Nitrates Directive. This means application will no longer be limited to 170 kg N/ha. RENURE fertilizers are based on processed manure fractions replacing chemical fertilizers.

Key product benefits:
• Pilot RENURE fertilizer
• Can replace chemical fertilizer
• Contains natural trace elements and sulphur
• Low in phosphate

Costs for farmers will be approximately €0 per ton delivered to the field (excluding application costs).

Application can be done using regular liquid manure injection systems. Low emission application techniques are compulsory to prevent ammonia volatilization. The mineral concentrate can be mixed with manure/slurry and/or diluted with water prior to application on grassland.

The soil improver is produced by separation at source of solid manure and urine. The calves stay on a steel slatted coated floor. The manure falls through the slatted floor on a perforated, urine permeable manure belt that lies under the grid floor. The urine falls completely through the perforated manure belt. The solid manure contains 40 % dry matter due to the direct way of separating. Almost no energy is needed to achieve this percentage (only electricity costs for running the manure belt). For the further processing of the solid fraction, a device is being developed that adds quicklime to the manure and further dries the manure with stable air (on a belt dryer) and then crumbles it. This creates an exportable crumb with a high dry matter percentage. Dry matter: 818 g/kg; Organic matter: 535 g/kg; N: 13 g/kg; P₂O₅: 9.4 g/kg; K₂O: 8.2 g/kg; C/N: 23. This high-quality soil improver can be sold both regionally and internationally (because it is hygienic). The product can be applied before sowing or planting of the crops with the same machines which are now being used for spreading solid manure. The fertilizer can be used at the cost of approximately €30/ton ex works. The product can be pelletized for easier handling and spreading (optional).

The nitrogen and potassium concentrate is produced using the VP-Hobe Manure Valorisation system. The input pig manure or digestate is first separated into a solid and a liquid fraction, using a flotation unit and a belt press sieve. A reverse osmosis unit processes the liquid fraction into a retentate concentrated N/K₂O product and a permeate product to be processed in the clean water production. The concentrated N/K₂O product will be further de-watered in an evaporator. The liquid passes through a falling film evaporator with mechanical vapour recompression. Heating the liquid in the evaporator causes water to evaporate. The evaporator reduces the potassium concentrate to 25% DM and 6.5% K₂O.
The potassium concentrate can replace potassium products based on mined potassium. This contributes to circular agriculture. Because the N an K are separated in two fractions optimal N/K balance can be achieved using precision fertilizing techniques using biobased fertilizers.
Key product benefits:
• Liquid organic potassium fertilizer
• Dry matter: 250 g/kg
• Organic matter: 75 g/kg
• N: 40 g/kg

Vlako’s solid fraction is produced from pig/cattle slurry using belt press sieve and pasteurization. The solid fraction has a dry matter content between 30 and 35% and gets pasteurized by infrared. By pasteurizing the solid fraction, it is free of pathogens like salmonella and E-coli, and can therefore be used for crops which are destined for human and animal consumption. Solid fraction can be used in: cereals, grains, dry pulses, protein crops, root crops and fresh vegetables. Solid fraction can be spread by lighter equipment and there are less tons needed to bring the same kinds of nutrients as when slurry is being brought to the fields. Where normally 6 to 10 tons of slurry is being spread, this can be replaced by using only 2 to 2.5 tons of solid fraction. This means that solid fraction is cheaper to transport and it can be spread with lighter spreaders which leads to less soil compaction. Application doses depend from crop application rates. Max 170 kg N/ha as livestock manure (230-250 kg N/ha for derogation dairy farms in NL). The product price varies during the season and is on average -/-€15 per ton ex works. This means that the producer pays €15 to be able to deliver the product. Average nutrient content is: organic matter: approx. 23%; N: 13.3 kg/ton; P₂O₅: 18.0 kg/ton; K₂O: 5.1 kg/ton. Due to the organic origin of the fertilizer, nutrient content may vary. For more information: https://nutriman.net/farmer-platform/product/id_594

Champost or "spent mushroom compost" (SMC) is a by-product of mushroom cultivation. It is a mixture of mushroom substrate and casing soil. For 1 kg of mushroom producction, there is 5 kg of SMC generated. This enormous amount of waste results in disposal problems. However, SMC has clear benefits towards agriculture and horticulture, such as high levels of nutrients (0.6% N, 0.4% P, 0.9% K) and high content of organic matter (about 21%), which is free of pathogens, weed seeds and odour. One cubic meter of spent mushroom compost corresponds to 2 to 3 tonnes of solid manure in terms of nutrient content. It also contains about 6–20% calcium in the dry matter, thanks to which it has the capacity to neutralise the soil acidity. The advantages of using SMC as a soil fertilizer over a chemical fertilizer is that it delivers slow-release of nutrients. Besides, SMC has a low bulk density indicating its relatively porous medium that can enhance the structure of the soils it is amended to. It can be used in several types of farming and for all types of crops, with an application dose of about 10-25 t/ha, depending on the local legislations. Good homogenisation is crucial. The cost varies between 10€/m³ and 25€/m³, mainly dependent of the amount and transport costs. Additionally composted SMC has an extra cost of 5€/m³ and has the advantage of lowering the salt content with 60%. For more information: https://nutriman.net/farmer-platform/product/id_1986

REVAWASTE Project is the sustainable management of a broad spectrum of wastes (industrial waste, non-recyclable fraction proceeding from waste treatment plants and agrofood waste) by application of the Multi-Waste Plan. The struvite (magnesium ammonium phosphate) precipitation in REVAWASTE project recovers the P contained in the disgestate and manure, in a form of a compound with fertilizing properties. The possibility of reusing the liquid fraction generated in the process for local consumption in the facility and in the vicinity area (irrigation, cleaning, etc.) is also a possibility.
Struvite precipitation is one of the processes to recover phosphorus from wastes, animal manure and digestate. The produced struvite has been found to be a good slow release fertilizer and provides essential nutrients (Mg, N and P) for agriculture and horticulture, with lower environmental risk of leaching, greater efficiency on its action, equal or even better effectivity for P and cheaper compared with regular mineral P fertilizers, without metal or other hazardous compounds, in the meantime reduces the costs of managing livestock waste.
The input materials are pig manure digestate, MgCl₂ and NaOH; and the struvite product has a NPK rate of 5-28-0, with a price at 250-400 €/t.
In the absence of approval of the framework for the new facultative European regulation on fertilising products, in many countries, struvite cannot currently be used as a biofertilizer, as it is classified as waste. It is recommended in conventional farming, overall in permanent grassland and arable land crops. The application dose is recommended to be 0.140 t/ha.

Struvite is a potentially marketable product for the P fertilizer industry. Its genuine slow release property can be more efficiently used by crops, because it meets nutritional demands of crops in a better way and prevents the burning of plant roots, even when applied in excess quantities, which guarantees a slow but steady nutrient supply. Moreover, struvite is an effective water-soluble phosphorus fertilizer in neutral and slightly acidic soils.
The amount of phosphorus and magnesium that the struvite could provide is higher than typical fertilizers (12% P and 9% Mg). However, the amount of nitrogen is lower than typical fertilizers (around 5 %N) and the percentage of potassium is very low so it is recommended to apply combined with conventional fertilizers to satisfy N and K demand. It can be easily combined with other solid fertilizers or dissolved in a slightly acidic solution.
Cd has not been detected and the amount of organic matter is very low, TOC is lower than 0.8%, thus it is a secure environmental friendly product.
The struvite recovered is highly recommended for cereal crops and grassland, although it is also useful when applied on fruits, vegetables and root vegetable as potatoes.
At Calahorra WWTP, with a population equivalent of 70,000 p.e. (24,000 inhabitants), it can be recovered about 9 t/yr of struvite. This struvite is not in the market yet but, based on market studies, the expected price would be about 200 €/t.
During the agricultural assays carried out, the application dose was 1,170 kg/ha of struvite for potatoes and 921 kg/ha for wheat.

REW Regenis offers the "Regenis GE separators" with which the amount of manure in the fattening can be reduced by up to 20% using up to 80% of the bioenergy contained in the slurry as WIN-WIN situation in Biogas production. It is often used after biogas plants in the nutrient circle behind animal production and before crop production on the fields.
The Regenis separator is a pulling screw separator, which performs the water separation and the pressing process separately. The solid is fed to the Regenis GT dryer. The Regenis GT fermentation residue dryer is a fluidized track indirectly heated by flue gases. On the discharge side, the dried fermentation residues are discharged downwards, and the flue gases cooled during indirect heating are discharged upwards into the chimney. The Input capacity for the dewatering process stage is between 1,000 - 4,000 kg/h and for the drying stage between 250 - 1,000 kg/h. The dewatering and dryer unit takes 100% of Fermentation residue.
The processes are highly efficient with low energy use and operating cost (about 6 EUR/t). 50% of thermal energy input is recoverable, by heat recovery out of the steam which comes out of the dryer. The technology requires only a hundredth of the exhaust air compared to the belt dryer but achieves a high separation rate of nitrogen and phosphor at 30% - 60%. A sanitation of the products takes place at the same time.
Regenis GT dewatering & dryer unit removes the fermentation residue from the customer and concentrates the nutrients in hygienized solids and liquid fertilizers. Very low operation cost by day and night operation with low energy use. The emissions are also reduced by using compact washer.

Since decades, farmers worldwide have successfully and reliably applied decanter centrifuges for the separation of nutrients from manure or digestate. Where other common mechanical separation technologies are based on filtration, decanter centrifuges use g-force and are therefore able to separate also the finer particles, thereby increasing the nutrients content of the cake fraction. Decanter centrifuges are able to operate with and without chemical flocking aids, depending on the desired result. Due to the high cost of additives, usually the separation is performed without them. The decanter typically removes between 70% and 90% of phosphate compounds and between 30% and 40% of nitrogen compounds. After separation, these substances are to be found in the crumbly solid phase, which can easily be transported with conveyer belts and stored. The liquid phase is then spread on the fields as previously. Amongst other benefits, decanter centrifuges should be definitely considered when the best separation performance is required or when limited space is available. Due to the specific needs of manure and digestate separation, GEA had designed a specific decanter line to meet our customers’ requirements: the GEA manure Decanter pro line is a collection of 6 decanter sizes with a capacity from 2 until 80 m³/h. When higher capacities and/or higher g-forces are required, we can offer the GEA manure Decanter prime line, with machines up to 140m³/h manure per hour. Basic prices range from €50,000 up to €250,000. For more information: https://nutriman.net/farmer-platform/technology/id_1343

Poul-AR® pre-treats chicken manure at an economical minimal input of 15 tonnes (dm)/per day to make the poultry dung for further anaerobic digestion (biogas). The treatment consists of mixing poultry manure and digestate from the digester, whereby grit, other contaminants as well as the ammoniacal nitrogen are removed from the mixture. The treated poultry manure can then be fed to a (CSTR/thermophile) digester without causing high ammonia-related problems.
With the Poul-AR® installation up to 80% of the nitrogen is removed, making the substrate useable in a mono-manure digester (or a co-fermenter). This makes the system interesting for large poultry farms or clusters thereof. In addition, in terms of biogas production, chicken manure is comparable to maize. Replacing maize with chicken manure can therefore bring considerable economic and ecological benefits. The N-removal though stripping and acidic washing leads in its own right to an ammonia-fertiliser. More particularly the Poul-AR® pre-treatment consists of 2 steps: (1) the ammonification, a batch process (24h) in which the ammonia is set free from the manure. (2) the de-ammonification, where the ammonia is stripped from the manure (and washed with an acid to produce N-fertilizers). Current at TRL7, the technology is – after the 2019 start-up of a full-scale installation – expected to become TRL 9 from 2020 onwards.

The AMFER® (AMmonium FErtilizer Recovery) stripping technology enables biogas plant owners to recover nitrogen from the digestate as a valuable fertilizer. Ammonia is removed from the liquid and washed with an acid to produce an ammonium salt like ammonium nitrate or ammonium sulphate. The produced fertilizer has a nitrogen content of 7% (ammonium sulphate, 35%) or 18% (ammonium nitrate, 52%). The AMFER® is primarily designed for digestate, but can also operate on all kinds of waste streams. The system is operated as a batch process or as a semi-continuous process. The AMFER® process tank is designed to enable the treatment of thicker and more viscous products, up to 10% d.m. Therefore any digestate from biogas plants can be treated in the AMFER®, without separation up front. A typical removal efficiency is 50% on mineral nitrogen, although removal of > 85% is also possible. The AMFER® is available at any size needed, starting from a 10.000 tons / year digestate. There is from a technological point of view no maximum size. The installation is designed to operate at relative low temperatures, typical waste heat can be reused from biogas plants. In proper maintained conditions there are no emissions to the environment, thus using the AMFER® reduces nitrogen emission from manure storages. The AMFER® can also be used to control the Nitrogen levels in the digester, which is required when feeding nitrogen rich streams like poultry manure, wheat or slaughterhouse waste. Another benefit is that the AMFER® process can be used as pasteurisation. That’s important when feeding animal byproducts, or when the digestate needs to be exported.

TerraSaline S (ASL) is an innovative technology converting ammonia sulfate solution (ASL) to a defined granulated fertilizer product. The input material is ASL of any concentration from of any concentration, for example from digestate, manure recovery or other streams. External heat is needed (e.g. from a biogas plant or similar). It allows to produce a nitrogen fertilizer out of natural resources like digestate, manure or similar. So, the need of buying mineral fertilizer is reduced, and the system helps to close the cycle of nutrients in a region.
The TerraSaline S (ASL) consist of a humidification/dehumidification section, where the ASL is concentrated until the salt (ammonium sulphate) falls out. This wet ammonium sulphate is then dried in the drying section and can be either packed into an integrated big bag unit or transported to the optional TerraGranulator which produces a defined fertilizer corn (3 to 8 mm) of the ammonium sulphate by mixing it with lime. A big bag packaging system is also integrated in the container.
The available capacity is 3 m³/day of ASL (modular). The technology is available in a modular system to adjust to needed size on market.
The output material is an environmentally friendly ammonium sulphate fertilizer, with 21 % N, 24 % S, optional added with lime. The product is a defined fertilizer out of undefined ASL-solutions, so the recovered nitrogen fractions can be used in a much broader and more targeted manner. The fertilizer can be easily stored in big bags or in bulk and is applicable with conventional fertilizer spreading technology. A further advantage is the reduced need of storage capacity compare to the liquid N-fertilizer.

The BENAS biogas plant yearly treats more than 80,000 ton of crop, food waste and poultry manure and produced biogas, mineral N, calcium-carbonate and organic soil fertilisers. With a modified stripping process, it reaches a recovery rate of 80% of ammonia contained in the digestate, which is approximately 200 t/y. It requires the addition of Flue Gas Desulphurisation-gypsum (FGD-gypsum) to produce two marketable fertilizers: 25% ammonium sulphate (AmS) solution and solid calcium carbonate fertilizer (Lime, 70% DM). The productivity is AmS 5-40 t/d and Lime 1.5-14 t/d. The gypsum used for the process comes from FGD of coal power plants. It increases the soil pH, enhances nutrient availability without causing alkalinisation, and also provides Calcium as an important plant nutrient. Moreover, the process does not require any external heat source and relies solely on the exhaust heat from the CHP engine, with an average consumption of 100 kWh/m3 of digestate. The process further implements with the FiberPlus System has achieved the production of ammonia-free fibers suitable for different applications in the fiber and timber industries (i.e. fiberboard). Emissions and loss of N are reduced. Recovered nutrients in the system are 67% of NH₄-N as AmS and 6% of NH₄-N as Lime; 6% of P and 5% of K as fibers. The BENAS technology also help to reduce the transportation costs and costs for storage of the digestat. This serves an important step for the waste treatment and for closing fertilizer loops.

Anaerobic digestion (AD) is a well-established method for the treatment of organic (waste) streams and for biogas generation. The hygienised remains of biogas production – digestate – contain the resilient organic fraction, water, and micro- and macro-nutrients from the digested (pig) manure and other organic (waste) streams. Post-digestion of the manure-input line at Biogas Bree (B) consists of separating in a solid and liquid fraction and/or drying (belt dryer/fluidized bed dryer) the solid fraction while scrubbing the exhaust air, saturated with ammonia, with sulfuric acid. In a chemical scrubber, acid is added to the washing water to remove the ammonia and a part of the odour compounds from the exhaust air. Water, acidified with sulphuric acid (96% or 98%), flows continuously over the filter package. This humidifies the filter. The acidic washing water reacts with the ammonia in the air. A salt (ammonium sulphate) is formed. Per kilogram recuperated ammonia 1.5 litres of sulphuric acid is needed. When the washing water is saturated with ammonium sulphate it is discharged - making room for new water and acid to form new washing water. About 15-20 litres of ammonium sulphate is produced/discharged per kilogram of ammonia that is recuperated from the exhaust air. The specific model Biogas Bree handles is a modified scrubber using the ammonium sulphate solution as a first-step dust washer.

Slurry as a fertilizer does not contain enough sulphur for the crops. The majority of slurry applications are thus compleated with the use of mineral NS fertilizers in order to supply needed sulphur. This is particularly important for grass and rape, where 30–45 kg/ha S is reccomended. Sulphuric acid (SA) is a wasteproduct from industry. It is less than half price of compareable mineral ammonium sulphate fertilizers and with the exact same chemical formular. In-field acidification systems injects SA into the slurry while it is being applied to the field. 1 liter of SA contains 580 g of S. The process of injection into the slurry converts the Sulphuric acid leaving the sulphur as a plant available sulphate. The 2 H bind themselves to the ammonia in the slurry, changing the gas form ammonia to an ammonium salt HN4. This process increases the nitrogen utilization rate from an average 20% to 80 % and dramatically increase the value of the slurry as a fertilizer. The farmer may stop using NS mineral fertilizer as it has more environmental benefits together with a profitable use of slurry as a fertilizer. The acidity of the slurry increases its plant available P by 40 % by breaking CA bonding of the P. The process is automatic without any possible user contact to the Sulphuric acid. It does not interfere with the slurry application logistics and it can be retrofitted to all types of slurry tankers in the market. The list price of the injection system is 65,000 € and it may be used up to + 100,000 m³ slurry each season. SA price is approximately 0.15-euro cent/kg. In-field acidification has been in the market for 10 years and is being used in 8 countries in 2019. For more information: https://nutriman.net/farmer-platform/technology/id_277

The digestate of Arbio (biogas installation digesting 90 kilo tonnes manure and organic wastes/y) is separated into a liquid and a solid fraction. The liquid fraction is concentrated via Reverse Osmosis (RO; Turbin). RO is a process of physical separation in which all particles and macromolecules are retained under pressure leading to 60% water and 40% 'concentrate': an ammoniacal nitrogen liquid (animal manure-status Arbio). This concentrate is then 'back mixed into the drying of the solid fraction digestate - mixing of the mineral concentrate (N and K) over the solid fraction just before it goes to a (belt) dryer. If, finally, pelletised this results in an easy to distribute fertiliser-pellet with an optimised (higher) N/P-content - 5.5% N (TN) of which 50% mineral N -, and 2.8% P₂O₅. At the end of 2019 the full industrial scale of the NPirriK post-treatment flow can realise about 3,000 tonnes/y of the high N/P-pellets. The market price for the pellets is estimated to rise due the optimised post-treatment add-on from 25 €/ton to 45 €/ton. The second RO-stream - water - can under certain conditions be either discharged into surface water, used as process water or, in case of drought, be used to irrigate nearby agricultural plots. The conversion to the NPirriK-concept allowed for a considerably lower amount of digestate to be treated via a biology, hence lower N destruction, lower transportation cost and overall lower energy costs.

If, finally, pelletised this results in an easy to distribute fertiliser-pellet with an optimised (higher) N/P-content - 5.5% N (TN) of which 50% mineral N -, and 2.8% P₂O₅. At the end of 2019 the full industrial scale of the NPirriK post-treatment flow can realise about 3,000 tonnes/y of the high N/P-pellets. The market price for the pellets is estimated to rise due the optimised post-treatment add-on from 25 €/ton to 45 €/ton. The second RO-stream - water - can under certain conditions be either discharged into surface water, used as process water or, in case of drought, be used to irrigate nearby agricultural plots. The conversion to the NPirriK-concept allowed for a considerably lower amount of digestate to be treated via a biology, hence lower N destruction, lower transportation cost and overall lower energy costs.

Detricon stripping/scrubbing recovers ammonia from liquid fraction of manure, digestate or other liquid waste streams with more than 0.1% ammonia nitrogen. The technology produces a technical pure-end product, ammonium nitrate, which can be used to enhance the growth of corn, grass, vegetables in conventional farming. Stripping/scrubbing by Detricon is an energy efficient and economic interesting technology to produce locally a pure nitrogen fertilizer without other nutrients. It is an example of circular economy. First, the manure needs to be mechanically separated, then the liquid fraction is transferred to the stripper/scrubber. Under the influence of pH and temperature, the ratio ammonia/ammonium can be increased so that the ammoniacal nitrogen can volatilize more quickly. By blowing in air, the volatile ammonia is removed from the liquid fraction and the nitrogen can be recovered. The air from the stripper, enriched with ammonia, is chemically bound to ammonium nitrate by nitric acid in the
scrubber. The concentration of ammonium nitrate is determined by the initial amount of water in the scrubber and the amount of nitric acid added during the process. In the Detricon process the concentration is set to 52 mass% ammonium nitrate which corresponds to 18 mass% N. After the ammonia in the scrubber is chemically bound, the ammonia-poor (<20 ppm NH3) air goes back to the stripper. The Detricon technology produces 100-5,000 ton/year inorganic fertilizer. The cost is 300,000 euro for 3 m³/h stripping/scrubbing and 550,000 euro for 8m³/h
stripping/scrubbing, with opreational fee at 0.9-1.2 euro/ton depending on the market value of the produced liquid ammonium nitrate.

This technology provided by Circular Values offers an extraction of nitrogen from a variety of possible waste streams (liquid slurries, liquid fraction digestate, discharged water,..). First the slurry, digestate or discharged water is separated for further treatment of the liquid fraction. Then the stripping is performed by blowing air through the liquid fraction of the slurry or digestate while increasing temperature or pH (e.g. with CaOH) which will gasify the mineral nitrogen (NH₃). Afterwards the NH₃-filled air will be washed with acidified (HNO₃ or H₂SO₄) water (scrubbing) to capture the ammonium again in liquid form (ammonium sulfate from H₂SO₄ or ammonium nitrate from HNO₃). Circular Values static units can be profitable when the farmer has production of 4,000 kg N and more (>1000 tons manure/digestate). For lower than 4,000 kg a mobile Circular Values solution can fit. The recovery capacity is up to 85% of the ammonium-N from the slurry or digestate. Furthermore, since it is a closed process no further emissions occur. As it removes the ammonium the NH₃ emission for the digestate or manure is reduced. A high quality fertilizer replaces the production and use of an artificial fertilizer. This technology offers solutions for intensive husbandry in any EU region.

N2 plasma manure processing technology is used to treat manure on the farm and turn it into an environment-friendly organic fertilizer. The plasma unit uses only (preferably renewable) electricity to capture nitrogen from air and add it to manure. This eliminates the ammonia and methane loss both in storage and during field application and makes the otherwise lost nitrogen available for the plants. It creates an economic benefit and makes livestock production more sustainable by reducing ammonia and GHG emissions.
The plasma technology uses electricity to fix nitrogen from air forming nitrogen oxides. In the absorption system, the nitrogen oxides are absorbed to neutralize the liquid to a pH around 6. Combined with free ammonia the oxides react to form a stable ammonium nitrate fertilizer, doubling the mineral-N content from the input product.
The available capacity of the system is 3,000 to 4,000 t/year per unit.
The price for the product is under development.
The output product is a liquid fertilizer with a performance that matches chemical nitrogen fertilizer. The ammonium nitrate is immediately available for plant uptake and is best applied when the plant needs nitrogen most.
There are several benefits proven:
- Reduce ammonia and GHG emissions from manure storage and field application
- 30% increased crop yield compared to untreated
- Save cost by substitution of chemical nitrogen fertilizer
- Plasma treated product does not smell like manure

Digestate_100% is a technical innovation effectively applicable in farms. It is an integrated system capable of converting the digestate into a valid business resource. In particular, digestates are processed into secondary products: a solid palpable fraction; a dense fraction; a largest proportion microfiltered digestate.
Electricity necessary for the separation and microfiltration of digestate is almost 25-30 A. No water is used in the digestate processing.
The microfiltration of digestate can be optimally combined with the drip lines for fertigation, as it is able to guarantee a microfiltered fraction in which all particles larger than a defined diameter (which depends on the spacing sieve) are excluded so they can't clog up the drippers.
Thanks to its capability to maximize the fertilizer efficiency of the digestate, distributing it directly on growing crops, the system allows to significantly reduce the use of mineral fertilizers (up to zero).
It is potentially useful not only in the field of industrial crops but also on fruit and vegetable crops, even in organic farming.
The input materials are livestock slurry, digestates, sewage sludge. And the output product are microfiltered slurry/digestate/sludge.
Working capacity of the plant is estimated between 5 and 10 m³/hour, but it depends on farm organization. Indeed it can also be used in small farms treating few tons per day (<10 t/day).
NH₃ and N₂O air emissions can be reduced significantly thanks to digestate dilution and slow distribution through fertigation. NO₃- leaching/runoff can be reduced too, compared to conventional digestate application.

The VP-Hobe manure and digestate valorisation system is a robust proven technology operated at own processing plants. It achieves lowest possible operational costs (energy, additives) while produces several fertilizers, e.g. mineral- and potassium-concentrate, NH₃-water, Ammonium sulphate, as well as clean dischargeable water. The input manure is separated in a flotation unit and in a belt filter press which results in a liquid and a solid fraction of 30% dry matter (DM). The solid fraction is dried on a belt dryer to 90% DM. The liquid fraction (1.7% DM) goes to a reverse osmosis (RO) process where a retentate concentrated-N/K₂O product (3.4% DM) and a permeate are produced. The RO-concentrate or thin fraction will be further de-watered in an evaporator. The liquid passes through a falling film evaporator with mechanical vapour recompression. Heating the liquid in the evaporator causes water to evaporate. A vacuum lowers the boiling point, less energy is needed than when evaporating at normal atmospheric pressure. The ammonia in the incoming liquid is removed from the product flow by stripping and concentrated into NH₃-water (14% N). The evaporator further produces a potassium concentrate (25% DM) and an ammonium sulphate solution by scrubbing the vapour coming out of the evaporator. The condensate from the Evaporator/ Stripper/ Scrubber (ESS) unit and the permeate from the RO is cleaned in the RO water polisher and the ion exchanger (RO-IE) to achieve the right quality for discharge into surface waters. The capacity of the technology is scalable: 50,000, 125,000, 250,000 ton input/year. For more information: https://nutriman.net/farmer-platform/technology/id_669

By adaption of a stable system, pig manure is being primary separated in solid manure and urine in the stable. The main advantage of this primary separation technique is that there are less ammonia, GHG emissions and odour in the stable which is better for the health of the farmer and animals.
Another advantage is that this technique implies a better biogas potential for the solid manure, because it is removed on a daily basis and therefor remains fresh. Moreover, the urine is better suitable as a fertilizer because it contains most of the nitrogen and potassium and not phosphorus limited. So with a VeDoWS stable construction the pig-farmer gets a good fertilizer (pig urine) for free.
When calculating total costs, this technology would not be more expensive than a classic stable system (with grid floor) and an end-of-pipe technique (such as an air washer). Price: 80-90 euro per pig place and operational expenditure: maximum 1.50 euros per pig place yearly.
The stable construction more in detail: underneath the slatted floor of the VeDoWS stable system a shallow cellar is constructed which enables the primary separation of urine and solid manure. The cellar consists of two inclining parts with an opening of 18 to 22 mm in its middle. Using a scraper, the solid manure is removed from the manure gutter daily. This primary separation of manure in the cellar is the basis of lower ammonia emissions. There is no need for chemicals by using this technique.

TerraOrganic FFT&HEF is an innovative technology system for nutrient separation and recovery from digestate, manure and wastewater. The TerraOrganic FFT is a solid-liquid separation, based on a press screw and a (mechanical) micro filtration. This allows the separation in a solids phase, a thickened sludge, and a liquid phase. The thickened sludge contains up to 50% of the phosphates. The liquid phase, which contains main part of the N fraction, is transported to the TerraOrganic HEF. The TerraOrganic HEF is a humidification/dehumidification system, combined with an Ammonia stripping. It extracts 10 m³ per day of water and recover all the Ammonia and Ammoniac by producing a defined liquid fertilizer as ammonia sulphate solution (ASL). This ammonia sulphate solution can be used directly or be added to the thick sludge to produce an N,P fertilizer worthy of transport. The separation into solid/liquid phases results in a significant reduction in volume and concentration of nutrients. This significantly increases the transportability of the produced recyclates.
The technology is available on the market. The capacity is available for 35 to 240 m³/ day, modular. The system can reuse the heat of a biogas plant or similar to meet the operation requirements.

The composting plant in "Biociclo" is able to treat 69,000 t/year of biological sludge, yard trimmings and food residues. Particularly the composting plant produces 20,000 t/year of high quality compost. Initially, organic and plant waste is delivered separately. The pre-treatment of the organic fraction is then performed in the transfer department, separating the unwanted fractions and then mixing the different waste matrices in the quantities determined by the shovel gummed. Waste undergoes an aerobic treatment which takes place in a large enclosed space in an environment under pression. The intake system constantly conveys the air present in the covered structure into the external filters to be purified. During the maturation the product stabilizes and becomes enriched with humic molecules. Finally, the compost is ready to be reused in agriculture, nursery and hobby. The duration of the biological transformation process to obtain the compost is 90 days and the accelerated phase of the process takes place in 7 biocells and subsequently in a controlled maturation phase in 28 ventilated boxes. The whole transformation process is managed by a remote control system. The air sucked in by the aerobic treatment department is purified, before being released into the atmosphere by a double abatement stage: scrubber (washing the air with water jets) and natural biofilter.

ACEA Pinerolese Industriale S.P.A. takes care of treating municipal organic wastes for the production of biogas and digestate (sludge quite stabilized and hygienized). The company serves a user basin of about 1 million of inhabitants for the treatment of organic waste. The current capacity is 60,000 t/y of organic waste. The first phase of the process consists of an anaerobic biodigestion (in the absence of oxygen), which allows the recovery of material (compost) with an innovative energy recovery system (biogas). In the future framework, all the biogas is going to be used for biomethane production. Digested organic waste (digestate) is dehydrated and then sent to the composting system, integrated to the facility. The biogas obtained from fermentation is conveyed to a gasometer and temporarily stored. The water used in the process is partly recirculated, while the remaining portion is sent to the wastewater treatment plant, integrated to the facility. The process produces biogas, a natural gas rich in methane. The biogas coming from the plants of the Integrated Environmental District of ACEA together with the biogas from the landfill and the biogas from the wastewater treatment plant, is stored in a gasometer. The mixture of biogas is sucked from the gas-holder, cooled and sent to 3 Otto cycle engines (the total nominal power is 3 MW). The electricity and the heat produced are used for internal consumption and the excess is transferred to the electric grid and to the district heating, respectively. The enhancement system of biogas for energy purposes developed by ACEA prevents the dispersion of biogas into the atmosphere. Compost is a final product (end-of-waste).

The most efficient and sustainable way of recycling nitrogen (N), phosphorus (P), other nutrients and carbon in the farming system, is recycling on the farm itself. One way of doing this is farm composting of crop residues and other farm organic materials. Composting is the controlled aerobic breakdown and transformation of a mix of organic waste streams as crop residues, feed residues, straw, solid animal manure, wood chips, etcetera. The composting process is performed by the activity of microorganisms and fungi. It is important to control process conditions as temperature and humidity. Turning and wetting of the compost pile should be performed accordingly. During the composting process, a hygienisation of the material occurs reaching a temperature of 60-65°C. The resulted compost is an ideal soil improver containing stable organic matter, recovered nutrients and microbes. The specific nutrient content depends upon the feedstock materials, but is mostly in the range of 0.5- 3% N, 0.2-1% P₂O₅, 0.5-2% K₂O. Almost all P is recovered, but some N (typically 5-20%) can be lost during composting, mostly by gaseous emissions. Compost acts as a slow release fertilizer, additional nutrients are released upon mineralization in the soil. Moreover, compost can also be used as peat replacement in growing media. Compost can be applied for all crops by the same application methods as farm yard manure.

Selectively retrieved VFG-waste is shredded, stripped of impurities (iron, glass, plastics), heated with steam and fed into a dry thermophilic anaerobic digester (OWS) that yields digestate and biogas which is partly used as a fuel for 2 CHP’s (combined heat and power-motors Jenbacher and MAN) in situ. The biogas is upgraded via membrane technology for gas grid injection. Planned expansion of IOK's processes is to capture the CO₂ (during biogas upgrading) and use it as a nutrient in surrounding greenhouse crops. The minerale-rich digestate is mixed with (sieved, de-ironed and shredded) green waste in an intensive composting process: this aerobic digestion phase in a closed hall mimics the natural conversion process from organic matter to humus in the soil (humification). This composting is also a controlled proces lasting a minimum of 4 weeks with minimum 3 turns, after which sieves (16mm) are used to separate the compost from the overflow fraction (recirculating to shredder/start of composting process). To ensure hygienisation of the end product (vfg compost) the following minimum temp/time- are upheld and controlled: thermophile digestion of min 2 consecutive weeks
>50°C, followed by min. 2 weeks composting at min. 45°C of which min. 4 days at min. 60°C or min. 12 days at min. 55°C. The sieved matter (<16 mm) further post-composts and matures, including further turning of the piles, outside for about 8 – 10 weeks. This robust technology can be used in all EU regions where vfg- and green waste are selectively retrieved. It produces clean energy and over 25.000 t/y of a hygienised and stabilised high quality soil improver with slow nutrient release.

Selectively retrieved VFG-waste is shredded, stripped of impurities (iron, glass, plastics), heated with steam and fed into a dry thermophilic anaerobic digester (OWS) that yields digestate and biogas which is partly used as a fuel for 2 CHP’s (combined heat and power-motors Jenbacher and MAN) in situ. The biogas is upgraded via membrane technology for gas grid injection. Planned expansion of IOK's processes is to capture the CO₂ (during biogas upgrading) and use it as a nutrient in surrounding greenhouse crops. The minerale-rich digestate is mixed with (sieved, de-ironed and shredded) green waste in an intensive composting process: this aerobic digestion phase in a closed hall mimics the natural conversion process from organic matter to humus in the soil (humification). This composting is also a controlled proces lasting a minimum of 4 weeks with minimum 3 turns, after which sieves (16mm) are used to separate the compost from the overflow fraction (recirculating to shredder/start of composting process). To ensure hygienisation of the end product (vfg compost) the following minimum temp/time- are upheld and controlled: thermophile digestion of min 2 consecutive weeks
>50°C, followed by min. 2 weeks composting at min. 45°C of which min. 4 days at min. 60°C or min. 12 days at min. 55°C. The sieved matter (<16 mm) further post-composts and matures, including further turning of the piles, outside for about 8 – 10 weeks. This robust technology can be used in all EU regions where vfg- and green waste are selectively retrieved. It produces clean energy and over 25.000 t/y of a hygienised and stabilised high quality soil improver with slow nutrient release.

VALUVOIL technology demonstrates the viability of the improved two-phase anaerobic digestion process for biofuel production and the potential uses of the organic by-products for stimulating plant growth and as compost for improving soils.
In VALUVOIL technology the vegetable oil waste mixed with pig manure is transformed to obtain biogas and digestate.
This technology benefit due to reduction of water and soil pollution (1 L of waste improperly disposed could contaminate 1,000 L of water). It was achieved though biofuel production, bio-products used as fertilizers, and reductions in hazardous sludge and safe disposal in landfill sites. Besides, it also boost the oil recycling market with diversification of market by new environmental friendly bioproduct and valorization of residues generated in other industrial processes.
The current capacity of this process is 50 L/h. The digestate obtained is not ecotoxic and its macro and micronutrients content confers a fertilizing character and optimum agronomic quality. Plant growth assays were carried out in growth cambers with different species and soils, the results also confirmed in germination tests with the highest plant yields obtained at high rates (80 and 120 m³/ha). Germination tests were carried out to determine the phytotoxic effect, concluding that high doses had inhibitory effects, but when diluted at adequate doses a stimulating effect on root growth and seed germination was obtained. The effect of digestate on soils tended to increase the biomass and microbial activity, particularly at high doses. The applied intensity should depend on the characteristics of the soil and digestate.

MIX-FERTILIZER is an innovative system for the agronomic valorization of waste from the anaerobic digestion (decomposition without oxygen consumption) of pig manure and to improve the associated environmental impacts.
The main value of this process are:
- Technical, economic and environmental feasibility.
- The installed stripping prototype recovered 80 % of the nitrogen from the liquid fraction of the pig manure.
- Highly suitable for commercial purposes.
The treatment has a capacity of 1 t/d and a TRL 8. Prototypes to recover inorganic nitrogen from the liquid phase by stripping (physical separation of components from a liquid stream), the formulation containing an inhibitor to ensure the gradual release of nitrogen, and the application of the fertilizers and liquid fraction in field trials. The final aim is to obtain a new type of fertilizer with a mixed organic/mineral base, and with a gradual nutrient release due to the addition of the nitrification inhibitor 3-4 dimethylpyrazole phosphate, along with an aqueous effluent fraction for use in fertigation. Specific objectives included the management of the demonstration plant and optimal integration of the individual steps for treating 120 m³/d of digestate; recovery of the inorganic nitrogen from the liquid phase for further use in producing new fertilizers to replace the synthetic mineral content; validation of the advantages of the new fertilizers in field trials and use of the water obtained as a by-product for the fertigation of sunflower. The new fertilizers were produced by composting the solid fraction of the pig manure in a specific mixture with poultry manure and straw.

Green composting refers to the biological aerobic breakdown and stabilisation of selectively retrieved green waste (compostable, organic waste from gardens, parks and lawns). It is a controlled transformation process (measuring temperature and moist, turning, forced aeration, and/or increasing water content) in an outdoors and indoors environment. This process mimics the natural conversion from organic matter to humus in the soil (humification). At IMOG the green waste undergoes a 4-phase composting: (a) reduce (chip) and mix the green waste, (b) 5 weeks : set up compost heap on windrow with membrane and forced aeration, (c) 3 weeks: converting windrow to a higher pile (‘table’), (d) 3 weeks: conversion from table to table.
At the end of the maturation phase the compost represents about ½ of the input weight. The temperatures achieved by the microbial activity allow the hygienisation of the end product. Minimum requirements are 10 consecutive weeks 45°C of which 4 days at 60°C or 12 days at 55°C. Also a minimum amount of turning and moist monitoring is required. Composting in Flanders is among the most highly monitored in the EU. Technological elements of the recuperation process at IMOG site are a chippers, crane, wheel loader, turning machine, windrow machine, membranes and sieving machine. Last stage is the sieving of the compost (0-15mm) with additional short storage (ad hoc maturation).
This robust technology is applicable in all regions where sufficient green waste is selectively retrieved. It produces at IMOG-site over 10,000 t/y of a hygienised and stabilised high quality soil improver with slow nutrient release.

Anaerobic digestion (AD) is a well-established method for the treatment of organic (waste) streams and for biogas generation. Compared to the initial feedstock the digestate is homogenised, mostly hygienised (cfr EC1069/2009 (animal by-products)), and has a higher nutrient replacement value due to a parcial transfer of the organically bound N to ammoniacal nitrogen.
Agrogas digestate fractions come through several mesophilic and thermophilic digesters and separation (screw press or sieve belt), drying, MBR (membrane filtration) and/or Reverse Osmosis (RO): the digestion and post-treatments occur along a ‘vegetal line’ or a ‘manure/other animal by-products’-line which are completely separate lines. This allows to offer two different types of digestate to the market: with a non-animal manure-status or with an animal manure-status. In the later case, compulsory hygienisation is achieved through a thermophilic post-digester, followed by separation and drying of the solid fraction, while the thin fraction of the hygienized digestate is mostly further treated at the biological water treatment plant with membrane filtration (MBR). These post-treatments allow Agrogas to reduce volume and transport cost for NPK and organic carbon, and to increase product shelf life. In the post-treatment polymers are used for the screen (or ‘sieve’) belt press and iron chloride, antifoam and carbon source for biological water treatment. Agrogas treats 70,000 t/y into 60,000 t/y liquid fraction digestate (including concentrated and/or, thickened effluent) and 3,000 t/y dried digestate, leaving 1,000 to 2,000 t/y raw digestate and/or solid fraction digestate.

ALGAECAN project proposes a sustainable treatment model of salty effluents that combines cost-effective heterotrophic algae cultivation with spray drying of the collected microalgae to obtain a product of commercial interest as raw material for biofertilisers production or animal feed.
The coupling of wastewater treatment and microalgae production was proposed as alternative for reducing the production cost, now as an alternative to the utilisation of conventional wastewater treatment systems because the utilisation of microalgae allows recovering nutrients carried by the wastewater, while minimising emissions of greenhouse gases and saving energy.
In ALGAECAN project closed-loop technology in which no waste is created. Valorisation of the by-product as a biofertiliser as a substitute for chemical fertilisers. The actual technology requires long hydraulic residence times and extensive surfaces. The obtained effluent would be suitable for industrial use, cleaning or irrigation, which implies decrease in the consumption of water.
The treatment system prototype is composed of three main steps:
1) a two-phase microalgae growing system, which consumes the organic matter and nutrients contained in the effluent;
2) a separation step to recover the clean water (that will comply with reuse standards), and;
3) a drying step to recover the dry microalgae (used as biofertiliser or animal feed).
This system is placed in two containers with solar panels that provide energy to the whole system. In case that there is not enough solar radiation, this technology will be supported by energy from biomass.

Manure and digestate are spread onto land to provide valuable organic matter and essential nutrients to maintain soil fertility and meet crop nutrient requirements. But, in some regions the applied amounts exceed the nutrient demand of crops and this surplus becomes an environmental problem. In these regions, manure and digestate disposal are an economic challenge for the farmers and operators of biogas plants.
SUEZ Green Tech GmbH focusses on the precipitation of phosphorus/nitrogen and the production of soil improvers based on manure and biogas digestate. The patented process enables to separately precipitate the valuable nutrients phosphorus and nitrogen and produce soil improvers from the solid fraction.
The input material is treated in several consecutive steps: First all nutrients bound in the solid fraction are dissolved, especially phosphorus. The second step is the solid-liquid separation. The solid output is already nutrient-poor and can be used as a peat substitute. In the third step the phosphate in the liquid is precipitated as phosphorus salt and finally nitrogen is recovered as ammonium sulphate by stripping.
At the end of the process a nutrient-poor water remains, which can be discharged or used for irrigation.
Compared with conventional fertilizer production, the life cycle assessment of the process is at least 60% better in the impact categories acidification potential, eutrophication potential, global warming potential, photochemical ozone creation potential and primary energy from nonrenewable resources.
The pilot is running in Germany (~10,000 yto) and the development of a full scale plant (~150,000 yto) is ongoing.

A management system for managing slurries has been put in place in the southern part of the province of Mantua, in Italy.
This technology allows to reduce excess nitrogen discharge through wastewater disposals. Furthermore, it’s possible to replace the silage corn with wastewater and to reduce the cost of power supply to the system. So it allows to increase the environmental sustainability of the energy unit (carbon footprint calculation). Finally, processing slurry and manure is useful to obtain a material more manageable for biogas plants, characterized by high homogeneity, high dry matter content (about 16%), high pumpability, without inert materials. The capacity of the plant is 60,000 t/year by processing about 25 t/hours.
The input material for the system are manure and slurry. The output product is a homogenised material more suitable for anaerobic digestion and more productive.
The process starts with the separation of slurries, which are carried out directly on the farm, with the separator already present in the farm or with a separator installed on a mobile vehicle. The material is sent to the biogas plants to stabilize the slurries, produce renewable energy and digestate.
One of the best opportunities of this technology is that users can include anaerobic digestion plants or farms that require organic inputs to maintain soil fertility. The separated solid can also be inserted in the vermicomposting process, which allows to enhance it in the agro energy supply chain within the biogas digesters in place of the corn shredded.

Local transporters collect the slurry from local pig, cattle or mink farmers and transport this manure to the manure storage at Vlako’s. The process starts in a reactor tank where sulphuric acid and ironsulphate are added to the slurry. From the reactor tank the manure goes to the sieve belt press. Within this press the liquid part of the manure, with minerals is separated from the solid manure, which will later be pasteurized for export and sales as organic phosphate fertilizer. The input capacity of the processing unit is 135,000 m³/year.
The liquid fraction is collected and send to the flotation unit. After the flotation unit the liquid fraction goes through a paper filter where left over organic materials are filtered out. From the paper filter the liquid fraction goes through the reverse osmosis where membrane filtration separates clean water from the mineral concentrate. Only after the last step of the process, the reverse osmosis, the product can be called mineral concentrate.
Reverse osmosis is considered a best available technique to separate clean water for surface water discharge, from liquid manure fractions.
The mineral concentrate is allowed as pilot RENURE fertilizer in NL which means that application is no longer defined as livestock manure in the Nitrates Directive.
Benefits:
• Technology proven in practice.
• Reverse osmosis is considered a best available techniques to separate clean water for surface water discharge, from liquid manure fractions.
• The mineral concentrate is allowed as pilot RENURE fertilizer in NL which means that application is no longer defined as livestock manure in the Nitrates Directive.

The calves stay on a steel slatted coated floor. The grid has a manure passage of approximately 50%. The manure is then placed on a perforated, urine permeable manure belt that lies under the grid. The manure belt discharges the solid manure several times a day to an air-tight collection outside the house. The urine falls completely through the perforated manure belt onto a coated sub-floor that is sloped and contains a urine trough at the lowest point. This pure urine then flows away to a closed collection outside the barn. Once a day, the coated sloping subfloor is sprayed with water so that no sediment formation occurs. The solid manure contains 40 % dry matter due to the direct way of separating. For the thick fraction, a device is being developed that adds quicklime to the manure and further dries the manure with stable air (on a belt dryer) and then crumbles it. This creates an exportable crumb with a dry matter percentage of 85 %. This high-quality fertilizer can be sold both regionally and internationally (because it is hygienic). This system produces urine as a potential RENURE fertilizer. The urine meets the proposed RENURE criterium C/N<3. The production and usage of RENURE fertilizers allows farmers to process their (excess) livestock manure into a RENURE fertilizer. This means that application will no longer be defined as livestock manure in the Nitrates Directive.

EasyMining recovers P from incinerated sewage sludge ashes. The Ash2Phos process can transform the sludge ash into raw material for phosphorus extraction and thereby be a part of a circular solution for phosphorus management. The process consists of 3 sequential steps: a first acidic step, a second alkaline step (where intermediate products are produced), and finally a conversion step where the intermediates are processed into final products. The process consists of several successive chemical reactions undertaken at room temperature (however one process step may benefit from a temperature of 40°C). There is no need for pressurized vessels or for exceptional materials to be used for the equipment. The mass balance of the process is favorable, since all input chemicals become part of the products.
More than 90% of P in the ash is recovered. The technology can use waste acid from incineration plants, with low labor intensity.
The main output product is calcium phosphate, this can be converted to superphosphate, di-calcium phosphate (41% P₂O₅) and mono-ammonium phosphate (61% P₂O₅, 12% N), all with cadmium content below 1 mg/kg P₂O₅.

AshDec® is a thermochemical process designed to convert the low plant available phosphorus compound from sewage sludge ash (Ca₃(PO₄)₂) to the highly plant available compound Rhenania-P (CaNaPO₄) while reducing the heavy metal content. The core process encompasses feeding ash to a rotary kiln where it is mixed with sodium compounds (e.g. Na₂CO₃) and a reducing agent, preferably sewage sludge. The material is treated at around 900 °C for 15-20 min. Sodium ions replace calcium ions in the phosphates and form citrate-soluble CaNaPO₄ compounds. Simultaneously, sodium reacts with silicon dioxide present in the ash and forms sodium silicates. The reducing agent is added to reduce the oxidized heavy metals. A noticeable high amount of heavy metals evaporates in their elemental form under the prevalent process conditions and temperatures.
The AshDec process is a robust technology to convert low plant available phosphorus compounds in biomass ashes (e.g. sewage sludge ash) to highly plant available phosphorus compounds. The output material is a calcined ash with 15-25 % P₂O₅. A plant should exceed a capacity of 15,000 t per year (1 t input ash ≈ 1 t of product output). No hazardous input or output materials are used. The P-Recovery rate of the process is > 95 % and there are no to very little amounts of residues and no by-products are produced. The product has a low content of contaminants, e.g. heavy metals (Cd, U, As, Pb). It has no organic compounds and is free of pathogens.

AshDec® is a thermochemical process designed to convert the low plant available phosphorus compound from sewage sludge ash (Ca₃(PO₄)₂) to the highly plant available compound Rhenania-P (CaNaPO₄) while reducing the heavy metal content. The core process encompasses feeding ash to a rotary kiln where it is mixed with sodium compounds (e.g. Na₂CO₃) and a reducing agent, preferably sewage sludge. The material is treated at around 900 °C for 15-20 min. Sodium ions replace calcium ions in the phosphates and form citrate-soluble CaNaPO₄ compounds. Simultaneously, sodium reacts with silicon dioxide present in the ash and forms sodium silicates. The reducing agent is added to reduce the oxidized heavy metals. A noticeable high amount of heavy metals evaporates in their elemental form under the prevalent process conditions and temperatures.

Uncontrolled struvite formation is a major cause of high maintenance costs and downtime on municipal sludge processing lines especially when combined with biological phosphate removal. The NuReSys technology wants to tackle these operational problems by controlling the struvite formation. It is a full scale proven technology and ready to contribute to a closed loop phosphorus driven feed/food agriculture. The advantages are the scaling prevention (based on limiting free soluble phosphate) and the improvement of dewatering of the bio solids, reducing the phosphorus load returning to the head of the municipal wastewater treatment plants (MWTP).
NuReSys technology can be applied on digested sludge or post dewatering. Even combining applications on both have already been designed and are operational at full industrial scale. The classical application of struvite precipitation is on MWTP at the outlet of the dewatering or on industrial water wastewater treatment plants at the outlet of an UASB reactor. A straight forward stripper/crystalliser combination can be installed. Struvite harvesting is quite simple because the struvite can easily be separated from the effluent. The second approach directly applied on digested sludge is a stripper for pH control and stirred tank reactor with MgCl₂ addition to promote active struvite formation.
The available capacity is 0.1-2.5 tons/day.
The produced struvite, Biostru © is a pure, contaminant free product ready for direct reuse or by preference as commodity product to be blended in with other nutrients to obtain an equilibrated nutrient ratio. Nutrient content (N-P-K %): 5.6 N 12.6 P 0 K - 10 Mg (% w/w).

The patented zero-waste Crystalactor® water treatment technology is used as advanced treatment of both drinking water and (industrial) waste water for removal of a large number of heavy metals and other inorganic compounds. The Crystalactor technology is a flexible technology that can be used for treatment of both large and small water flows. The heart of the Crystalactor treatment plant is the pellet reactor, partially filled with suitable seed material such as sand, garnet, or small crushed pellets.
Crystalactor is sustainable and cost-effective: compared to other technologies like precipitation, ion exchange or membrane filtration, it produces a valuable resource as revenue instead of waste and associated costs. Phosphorus is recovered in the form of calcium phosphate, magnesium phosphate or struvite by dosing lime or magnesium hydroxide, or a combination of caustic soda and magnesium chloride as reagents. Struvite formation occurs by dosing magnesium salts if the ammonium required for struvite formation is present in the water. The bulk of the phosphate is removed in the form of pellets from the reactor. Effluent filtration is usually required to remove suspended phosphate flocs that are present as carry over from the reactor. Other possible resulting resources are calcium carbonate, calcium fluoride, metal carbonates or hydroxides.
The technology is suitable for reducing the concentration from over 25 mg P/L to 0.2-0.5 mg P/L at loads over 1 kg P/h. The recently added advanced controller reduces the chemical, operational and maintenance costs by predictive control of formed pellets.

REVAWASTE by application of “Multi-Waste Plant” concept proposes the management and valorisation of different waste, such as plastics, the non-recyclable fraction of waste treatment centers and farm waste, in the same facility. A key aspect is the recovery of energy, for which two complementary technologies are proposed: an anaerobic digester to effectively convert biodegradable organic waste into biogas and a thermo-chemical treatment system to transform nonrecyclable waste into syngas. The digestate leaving the methanogenic reactor is introduced into a crystallisation unit and converted to struvite.
This procedure allows to recover the P and N contained in the digestate, in the form of a compound with fertilising properties that can be used in agriculture. There is possibility to reuse the liquid fraction generated for local consumption in the facility and in the vicinity area, as to treat waste streams of varied nature at the same facility can take advantage of synergies between different treatments and reduce the environmental impact produced by the deposition in landfills of the residual fraction generated in waste treatment facilities, which was classified as non-recyclable.
Valorisation of the effluent produced in the methanogenic step as struvite, with up to 95.4% of nutrients recovery, reduce losses of P and N to the soil or toxicity to plants. Biogas and syngas streams (energy content 6.5 kWh·m³ and 8.5 kWh·m³, respectively) can be successfully valorised under blended-fuel mode in an adapted gas engine generator maintaining the engine energetic performance under single-fuel (natural gas) mode.

Studies to recover and valorize the by-products coming from the agrofood production, reinforcing a more competitive and sustainable economic model through the efficient use of resources.
Benefits arise from this technology is food waste streams valorization to bioenergy and bioproducts and recovery of the digestate obtained in the anaerobic digestion process and struvite.
The crystallization of N and P in the form of magnesium phosphate and ammonium hexahydrate or struvite, is one of the possible techniques used to eliminate and/or recover nutrients from the digestate, obtaining a product that can be applicable as a base in ecological fertilizers.
Several factors influence the precipitation of struvite: the chemical composition of the residual effluent (organic matter, ionic strength), pH, the molar ratio of Mg:N-NH₄:P-PO₄ (Mg:N:P), the degree of supersaturation, temperature and the presence of foreign ions, such as calcium.
The reaction takes place at room temperature (25-30 ºC), so it is not necessary to make a large energy consumption and does not need the addition of water.
The raw materials used in this technology are pig slurry digestate, magnesium salt and NaOH.
The technology has a sufficiently relevant scale (crystallization reactor with a capacity of 50 L), so that the results can be used for subsequent implementation on an industrial scale.

The precipitation of struvite in the Madrid Sur WWTP is a problem when generating pipe obstructions, generally in the sludge line, downstream of the anaerobic digestion. Struvite is a crystal whose matrix is composed of magnesium, ammonium and phosphate, which is formed when these three ions are present in the solution above its saturation point. As a solution for this problem a Struvite Recovery System is implemented with a TRL level 9.
The Nutrient Recovery facility consists of 2 groups of feed pumps, a crystallizing reactor and its associated pumps, valves etc., a draining and drying product step, a product sorting and packaging step, a programmable logic controller (PLC) cabinet, an engine control center, a MgCl₂ and a NaOH storage tanks.
The draining of the dehydration and the clarification of the flotation are fed into the lower part of the reactor where they are diluted with recirculation and injected with MgCl₂ (32%) and NaOH (25%). Inside the reactor, the struvite precipitates in a controlled way in small hard granules. At the top of the reactor, an integrated clarifier retains the granules inside the reactor. The effluent is sent to a tank from where it is pumped to the primary decantation of the WWTP. Struvite particles are collected from the bottom of the reactor, washed, dried, sorted by size and packaged for shipment.
The system is designed to recover phosphate from a combined feed, in the range from 50 to 120 m³/h maximum anaerobic digested sludge, dehydration overflows and flotation overflows.
The system is dimensioned to produce 2 t/day of the product ready to be commercialized.

Several technologies are available for P-recovery at WWTPs, but none uses also the flows before the anaerobic digestion, thinking about the WWTP as a whole, considering biological processes and scaling problems. By controlling biological processes and struvite scaling, phosphorus recovery rate can be increased and avoid the operational problems due to scaling.
The innovation of PHORWater faces the problem from less to more; from optimization of the integral management to increase phosphorus availability and decrease uncontrolled precipitation of phosphorus, to a new simple-operational P-recovery reactor.
The obtained struvite (29% P₂O₅, 15% MgO, 5% N) is a potentially marketable product for the P fertilizer industry. Its slow release property avoids burning of plant roots, even if applied in excess quantities. Insoluble nature of struvite in neutral water prevents eutrophication and restricts leaching into groundwater. Regarding to impurities, the obtained struvite has less metal content than the phosphate rock, very low organic matter and less micro pollutants content than an anaerobic sludge. The struvite can be spread on the soil combined with other fertilizers or dissolved in a slightly acidic solution. It is highly recommended for cereal crops and grassland, but it is also useful on fruits, vegetables and root vegetable as potatoes.
At Calahorra WWTP, with a population equivalent of 70,000 p.e. (24,000 inhabitants), it can be recovered about 9 t/yr of struvite. The expected price would be about 200 €/t.
The application dose during the field trials was 921-1,170 kg/ha of struvite.

The term "Terra-Preta biochar" is a specific quality product with unique characters, which is processed by the "3R" Recycle-Recover-Reuse high temperature pyrolysis technology and formulations. Terra Preta biochar product is plant biomass by-product based stabile carboniferous substance that is processed under true value reductive “3R” thermal conditions, that is used for soil improver and and eco-safe carbon negative applications, usually between 5 t/ha and 20 t/ha. Terra-Preta biochar has high water retention capacity to improve drought tolerance. This is very important as many plant crops are very sensitive to abiotic stress as too hot and dry weather. The product is a fully safe and innovative soil improver with primarily application in the horticultural organic/low input farming cultivations with combined beneficial and multiple effects. The product could be formulated to BIO-NPK-C in any compounds as of user/market demands for both organic and low input farming. Terra-Preta biochar is rich in micro and meso-pores, which increase the water retention capacity, allow the development of microorganisms and retain nutrients, releasing them gradually over time. The combination of Terra- Preta biochar with compost, biophosphate, manure or another organic fertilizer is most encouraging for agronomic performance. Compost integrated application positively influences soil structure, including reduction of bulk density; increase of aggregate stability; improvement of pore volume; improved water retention; improved air balance; reduction of soil erosion and run-off; stimulating microbial growth and increase of Cation Exchange Capacity.

The alternative biomass which could be used as fertilizer are obtained by algae cultivation. Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. Duckweed (the Lemnaceae) is a family of aquatic plants that rich in protein. Both of them can make use of nutrients in solutions to produce biomass by algae cultivation which can be used as crop fertilizer.
Input material: fruit and vegetables processing industry wastewater.
Algal biomass as a new bio-fertiliser contains macronutrients and micronutrients, some growth regulators, polyamines, natural enzymes carbohydrates, proteins and vitamins implemented for improving vegetative growth and yield. It can improve soil characteristics that have favourable effect on nutritional status of plants. Microalgal fertilisers improve the fruit quality through an increase in sugar and carotenoid content. Some studies demonstrated that the performance of algal materials was similar to that of a conventional synthetic fertiliser or even higher.
The main bottleneck is that the nutrient composition of the microalgae is often lower than the requirements of the crop. Furthermore, these nutrients can vary throughout the production process and between different facilities. Therefore, it is important to know the exact composition before fertilisation.

Ammonium nitrate/sulphate refers to ammonium nitrate/sulphate solution recovered from stripping/evaporation + scrubbing process by nitric/sulphuric acid as scrubber.
Input material: liquid fraction of pig manure, poultry manure, digestate, sulfuric acid or nitric acid.
Ammonium sulphate and ammonium nitrate are odourless and suitable for replacing mineral fertilizers in agriculture. By stripping and scrubbing, it is possible to produce locally a pure nitrogen fertilizer without other nutrients. Another benefit of this ammonium sulphate is that it is providing sulphur as added value to meet the specific requirements of some crops.
The main bottleneck is that the composition of ammonium nitrate and sulphate may vary throughout the production process and between different installations. Another risk is that spraying of these products can give leaf damage. Also, under the current regulations, ammonium sulphate/nitrate derived from stripping/scrubbing is treated as livestock manure and need to follow the limit of max 170 kg total N per hectare (230-250 kg N/ha for derogation farms in NL).

Ashes are the burned-out solid residue powdery product after oxidative thermo chemical processing: oxidative combustion or semi-oxidative gasification processes.
Input material: organic residuals, including municipal sewage sludge, manure, green residue from urban collection, straw or wood and wood residuals.
The ashes contain several plant nutrients (calcium, magnesium, potassium, phosphorus) and have a low pH. Ashes have also a lime effect due to this basic character so they can be used for balancing the pH level on acidic soil.
After appropriate preparation, ash-based P-fertilizers provide highly concentrated P-fertilizers with good plant availability and low content of impurities.
Using ashes and ash-based material is closing material and nutrient cycles. They can represent a valuable resource as a substitute for finite minerally derived P fertilizers. In particular, the ashes obtained from sewage sludge represent a great recovery potential for phosphate. In addition to direct use, these material flows could also be used for the production of fertilizers in industry.
The main bottlenecks for the application of ashes are their lower nutrient concentration (biomass ash) and their fine, powdery structure. The ashes from sewage sludge subsequently require a further, complex, technical chemical or thermophysical treatment, so that the nutrients are more available and it is possible to reduce contaminants.

Compost is a humus-like material derived from organic waste composting as a result of the action of aerobic bacteria, fungi, and other organisms. Depending on composting method, size, intensity of the operation and the input material, a large range of qualities can be produced. Input material: many types of organic wastes are composted or co-composted. These can include green waste (public space management, gardening, municipal container parks, or separate municipal collection), vegetable-fruit-garden waste (separately collected organic fraction of municipal solid waste), food wastes, farm manures (pig and/or chicken), straw, algae and dehydrated effluent from wastewater treatment plants.
In general, compost application benefits are: provision of sufficient soil humus; improvement of soil structure; facilitated water infiltration and storage;feeding/activating soil micro- and microbiological organisms and thus soil biodiversity; counteracting soil acidification; provision of more or less slow acting (slow mineralization of organically bound) nutrients.
The main bottleneck for the application of compost in Northern Europe is when you have to apply the product in an area sensitive to nitrogen or phosphorus, according to the local regulation from directives 2000/60/CE and 91/676/CEE. Consequently, the application dosage must be chosen according to soil availability and crop uptakes.

Compost is a humus-like material derived from organic waste composting as a result of the action of aerobic bacteria, fungi, and other organisms. Input material: organic wastes, including organic fraction of municipal solid waste, green residue from separate urban collection, dehydrated effluent from wastewater treatment plant, food wastes, green wastes, farms’ manures, straw and algae.
Compost provides a good amount of organic matter, and the slower release of nutrients has positive effects on plants development, demonstrating to be able to substitute, at least partially, mineral fertilizers. Some composts (ID:210-260-540) areusable in organic farming. They are odourless products thanks to temperature monitoring and maturation time. These products are well-stabilized but able to increase soil fertility. They have a good effect on acidic soils.
Furthermore, ID 210 is produced from pre-digested selectively collected organic waste streams, and the integrated anaerobic digestion process allows producing also biomethane.
The main bottleneck for the application of compost in Southern Europe is when you have to apply the product in an area sensitive to nitrogen or phosphorus, according to the local regulation from directives 2000/60/CE and 91/676/CEE. Consequently, the application dosage must be chosen according to soil availability and crop uptakes.
Finally, for correct spreading, it is necessary to use a manure spreader equipped with reinforced chains.

Digestate is a fertiliser obtained from anaerobic digestion process where microorganisms break down organic materials in the absence of oxygen. Input material: all kinds of biodegradable organic wastes including animal manure, farmyard manure, green manure, food waste, food-processing wastes, municipal waste, corn silage, sewage sludge, effluent from wastewater treatment plant etc.
Digestate contains a good amount of nitrogen, phosphorus and potassium. After anaerobic digestion, the percentage of readily available nitrogen is higher in digestate compared to the same organic material in its raw form, thereby increasing its fertilising value. The recovery of nutrients from digestate as crop fertilizer can help to close the nutrient loops and contribute to a more sustainable agriculture. Additionally, organic matter in digestate can build up the humus content in the soil which is particularly crucial for arid and semi-arid lands with low carbon content.
The main bottleneck for the application of digestate in Northern Europe is that this product is still regulated as manure according to the Nitrate Directive (91/676/EEC), which means no more than 170 kg total N from digestate is allowed to be applied to the field. As 30-50% of the digestate N is organic, which is not directly plant available, the actual effective N supply may not fulfill the requirement of crop and thus need supplement from synthetic fertilizers. Besides, the slow-degradable organic matter from digestate may increase the risk of post-harvest N leaching if applied improperly.

Digestate is a fertiliser obtained from anaerobic digestion process where microorganisms break down organic materials in the absence of oxygen. Input material: biowastes, energy maize, pig manure, chicken manure from poultry farm, straw (residual vegetal biomass), urea, mix of manure and biowastes.
Treating the bio-wastes in biodigestion conditions it is possible to:
• Produce renewable energy.
• Reduce odours.
• Stabilize the manure and co-substrates: the demolition of the carbonaceous organic load resulting from the anaerobic digestion gives the manure a sufficient stability in subsequent periods of storage; it causes a slowdown of the degradation and fermentation processes.
• Reduce the pathogens content of the input materials.
The main bottleneck for the application of digestates is when the product is applied in an area sensitive to nitrogen or phosphorus, according to the local regulations from directives 2000/60/CE and 91/676/CEE.
For the transport and spreading of the liquid digestate (ID:268) a common slurry tank can be used. Given the high volumes of transport and the high level of humidity of the fertilizer, it would be better to promptly bury the distributed liquid digestate with a disc harrow or with a subsoiler, even better if combined with the slurry spreader in order to limit odour and ammonia emissions. It isn’t recommended to deeply plow immediately after the liquid digestate has been distributed as the soil, given the consistency of the fertilizer, is slimy and slippery, making the operation more expensive in terms of consumption and labour time.

Livestock manure from house usually contains high percentage of water which consist of urine, spilt feed and drinking water as well as water for washing. During physical separation, most of water retains in the liquid fraction, together with the soluble nutrients including mineral N, orthophosphate, K, etc. This liquid manure can be used as a liquid organic fertiliser in agriculture. Input material: raw (pig/calves) manure.
Liquid manure is a liquid organic fertilizer which can be used for several crops and in several types of farming. Due to the liquid composition, field application and dose is easy to set. It barely contains organic components, it is rich in mineral components and has a high N/P ratio. Once there is a stable system, it is a good fertilizer for free.
Furthermore, ID 591 is a potential RENURE fertilizer in NL, which means that it will no longer be defined as livestock manure in the Nitrates Directive and therefore the application will no longer be limited to 170 kg N/ha.
As a product recovered from manure, this liquid manure is legally treated as manure and therefore it cannot be used as chemical fertilisers in terms of the Nitrates Directive. Currently this product must compete with animal manure and has therefore no financial value yet. An effort is needed in a further concentration step to meet proposed criterions of liquid fertilising products of the new facultative European regulation of fertilising products if free trade within the EU is an objective. However, as mentioned above, it is a potential RENURE fertilizer in NL.

Mineral concentrate is the concentrated mineral nutrients solution obtained from membrane filtration process of waste streams or from another separation technology that concentrates the N in the end-product compared to the input. Input material: liquid fraction of waste streams rich in mineral nitrogen and phosphorus, including urine or slurry from animal husbandry, effluent of anaerobic digestion, dehydrated effluent from wastewater treatment plant.
The N and K in mineral concentrate from reverse osmosis process (ID:520-593-1504-1528) are mostly plant available, which shows higher nutrient value compared to unprocessed manure. Under controlled conditions (pot experiments) mineral concentrates are almost comparable with calcium ammonium nitrate (NFRV is approaching a full replacement value of 100%). In the field situation attention still has to be given to the application technique (surface broadcast or injection). Overall agronomic and environmental performances of mineral concentrates is in line with chemical nitrogen fertilisers.
As a product recovered from manure, these mineral concentrates (ID:520-593-1504-1528) are legally treated as manure and therefore they cannot be used as chemical fertilisers in terms of the Nitrates Directive.

Precipitated Calcium-Phosphate refers to P salt containing Ca2+, e.g. Ca3(PO4)2, CaNH4PO4, etc. produced by calcium phosphate precipitation technology. Calcium phosphate precipitation is very complex and involves various parameters. It depends on calcium and phosphate ions concentration, ionic strength, temperature, ion types and pH but also on time. When calcium hydroxide (Ca(OH)₂ ) is added to the liquid fraction and the pH increases above 10, and temperature (70ºC), phosphorus precipitates as hydroxyapatite (Ca5(PO₄)₃OH) or brushite (CaHPO₄ 2H₂O). Depending on dosage, three different Ca-phosphates can be obtained: the highly water-soluble mono-calciumphosphate (MCP), the citric acid soluble di-calciumphoshate (DCP) and the barely soluble tri-calciumphosphate (TCP). For fertiliser application, MCP and DCP are favoured. Input material: sewage sludge ashes.
The water solubility of precipitated calcium phosphate is low, but P is highly available as demonstrated by the high solubility in neutral ammonium citrate. It is already proven that phosphate is slowly released, the fertilizing efficiency is therefore high. It can be applied as such on the field (as root placed fertilizer or spread as granules with common equipment), or transformed into other phosphate fertilizers (MCP, DCP, MAP, DAP, etc).
The main bottleneck of precipitated calcium phosphate is that it is deficient in other important nutrients such as N and K, so it has to be be mixed with other fertilisers or nutrients (blending) to meet the requirements of each crop.

Scrubber water is the ammonia water recovered from waste stripping/evaporation process. Input material: liquid fraction of waste streams rich in mineral nitrogen, including urine or slurry from animal husbandry, effluent of anaerobic digestion, effluent from wastewater treatment plant etc.
High N liquid inorganic fertilizer derived from processed animal manure. The production and usage of RENURE fertilizers allows farmers to process their (excess) livestock manure into a RENURE fertilizer. In the Netherlands this product is a potential RENURE fertilizer which means that application will no longer be defined as livestock manure in the Nitrates Directive and its application will no longer be limited to 170 kg N/ha.
Under the current regulations, the ammonia water recovered from animal manure is still treated as livestock manure and needs to follow the limit of max 170 kg total N per hectare (230-250 kg N/ha for derogation farms in NL).
Another concern about the field application of the scrubber water is the ammonia volatilisation. Since the pH of recovered ammonia water is usually high (e.g. ±10), which gives even at normal ambient temperatures (15°C) 75% of the total ammonium in the solution to be present as ammonia gas (NH₃), and thus increase the potential of N loss via volatilisation. Therefore, reducing the pH to neutral, using solutions with a low ammonium concentration (1-3%) or a mix of ammonium solution with manure or compost can prevent ammonia losses to the air.

Livestock manure is a mixture of feces and urine, bedding material (e.g. straw, wood shavings, sawdust, sphagnum), spilt feed and drinking water, and water used for washing floors. It is a valuable fertilizer that contains a broad range of nutrients such as nitrogen (N), phosphorus (P) and potassium (K) as well as organic carbon which can be utilised by soil microorganisms. Raw manure can be processed with separation technologies that produce a solid fraction in which much of the P and dry matter (DM) and significant amounts of the N are retained. Input material: livestock manure (poultry, pig, cattle, calves).
Solid manure is a natural product with a high organic matter content. Therefore, the C/N ratio is high, which means that these products are well-stabilized but able to increase soil fertility. Depending on the used technology and input material, some additional benefits can be seen (e.g. organic phosphorus with high bioavailability, hygienic and free from pathogens).
It is necessary to choose the application dosage according to soil availability and crop uptakes. Also, under the current regulations, the solid manure is treated as livestock manure and need to follow the limit of max 170 kg total N per hectare (230-250 kg N/ha for derogation farms in NL).

Struvite (magnesium ammonium phosphate) is inorganic phosphate mineral with formula: NH₄MgPO₄•6H₂O and approx. 22% P₂O₅ content obtained from precipitation processes.
Input material: waste water, manure digestate or any other digestate dewatering liquor and P-rich industrial effluents.
Struvite (ID: 208, 250, 251 and 293) are white solids, odourless and easy to handle, even though they come from residual flows.
Due to their genuine slow-release property, nutrients are efficiently used by crops because they meet nutritional demands of crops in a better way and prevent the burning of plant roots, even when applied in excess quantities. Struvite guarantees a slow but steady nutrient supply and reduces nutrients runoff, consequently is not only good for the economics of the farm, but also for its sustainable agronomy.
In addition, Cd has not been detected and the amount of organic matter is very low, so it is a secure environmentally friendly product.
Finally, struvite is a recovered product with steady composition.
The main bottleneck for the application of struvite is the end of waste national criteria. Nowadays, in Europe it is approved to be used in agriculture in Belgium, Netherlands and Germany but it is still consider a residue in other countries, nevertheless the new European Fertiliser Regulation opens the door to its use in all of the European Countries and this Regulation shall apply from 16 July 2022.

Struvite (magnesium ammonium phosphate) is inorganic phosphate mineral with formula: NH₄MgPO₄•6H₂O and approx. 22% P₂O₅ content obtained from precipitation processes.
Input material: waste water, manure digestate or any other digestate dewatering liquor and P-rich industrial effluents.
Struvite (ID: 208, 250, 251 and 293) are white solids, odourless and easy to handle, even though they come from residual flows.
Due to their genuine slow-release property, nutrients are efficiently used by crops because they meet nutritional demands of crops in a better way and prevent the burning of plant roots, even when applied in excess quantities. Struvite guarantees a slow but steady nutrient supply and reduces nutrients runoff, consequently is not only good for the economics of the farm, but also for its sustainable agronomy.
In addition, Cd has not been detected and the amount of organic matter is very low, so it is a secure environmentally friendly product.
Finally, struvite is a recovered product with steady composition.

The urine is produced by separation at source of solid manure and urine. The calves stay on a steel slatted coated floor. The manure falls through the slatted floor on a perforated, urine permeable manure belt that lies under the grid floor. The urine falls completely through the perforated manure belt onto a coated sub-floor that is sloped and contains a urine trough at the lowest point. This pure urine then flows away to a closed collection outside the barn. It is a liquid organic fertilizer. Dry matter: 27.4 g/kg; Organic matter: 7.4 g/kg; N: 4.3 g/kg; P₂O₅: 0.1 g/kg; K₂O: 9.6 g/kg The urine that is produced meets the RENURE criteria (C/N < 3) that are currently proposed by the Joint Research Centre to the European Commission (from the Safemanure project). If the EC accepts the proposal, the urine can be disposed of regionally free of charge or for a fee as a substitute for chemical fertilizers to dairy farmers, arable farmers and / or horticulturalists. The product can be applied before sowing or planting of the crops with the same machines which are now being used for spreading slurry or liquid manure. During the cultivation of the crops the product can be applied with precision fertilising equipment. The use of low emission application techniques is compulsory to prevent ammonia volatilization. The fertilizer can be locally used at the cost of approximately €0/ha. For more information: https://nutriman.net/farmer-platform/product/id_591

In an VeDoWS adapted stable construction there is not only less odour, ammonia, GHG emission in the stable. Due to the primary separation of pig manure in the stable the farmer produces a good liquid fertilizer for free: pig urine. The VeDoWS pig urine contains most of the nitrogen and potassium, while the phosphorus is mainly found in the solid manure. The N/P ratio is high. Therefore the pig urine is suitable as a good fertilizer without being phosphorus limited. It can be used in organic and conventional farming, open fields and greenhouses, in all crops. Due to the liquid composition field application and dose is easy to set. As the nitrogen content is limited, not more than 50 tonnes/ha can be applied. Product features are: Organic carbon content (g/kg): 7.86 – 10.92 ; Total Nitrogen content (g/kg): 3.28 – 3.70 ; NKjehl content (g/kg): 3.32 ; C/N: 1.3 - 1.9 ; Phosphorus content (g/kg): 0.01 – 0.19 ; Other macro and micro elements (g/kg): K: 4.21 / Na: 2.15 / Ca: 0.42 / Mg: 0.42 Dry matter content: 0.6% – 2.7% pH: 8.70 – 9.26 EC (mS/cm): 24.2.
The solid manure is suitable as biomass feed for a digester because it is kept fresh due to a daily removal of the manure. Products features are: Organic carbon content (g/kg): 214 – 384; NKjehl content (g/kg): 11.97 – 16.8; C/N: 10.7 – 12.7 Phosphorus content (g/kg): 6.33 – 18.87; Other macro and micro elements (g/kg): K: 5.51 / Na: 2.06 / Ca: 8.23 / Mg: 3.54; Dry matter content (g/kg): 263 – 472.
The disposal cost for separated collection of manure and urine is also less expensive compared to non-separated manure.
In Belgium farmers are payed to come and collect pig urine on a pig farm with a VeDoWS stable construction.
