Anaerobic digestion
Anaerobic digestion is the fermentation process of organic matter in the absence of oxygen. Feedstocks are manure, crop residues or any other form of organic matter. The product of anaerobic digestion is biogas (CH4). Biogas needs to be upgraded to be able to use it in our gas network. The biogas can also directly be burned and used as heat or to produce electricity. Anaerobic digestion happens at different levels, from farm to regional levels, to even small scale with kitchen scraps. The technique is widely used and it's even more interesting in recent light, with rising gas and energy prices. The main advantage for farmers is the production of biogas. The digestate (the residual slurry after digestion) is still rich in nutrients and more uniform and can be directly spread onto the field. It can also be separated into a liquid and a solid fraction, so the nutrients can be applied to the field more precise. In case of digestion of manure before application on the field, this results in environmental profits like less greenhouse gas emissions (https://edepot.wur.nl/287471). A recent article in a farmers weekly reviews costs, benefits and realization of mono digestion of manure in the Netherlands (https://melkvee100plus.nl/financieel/vergisten-dagverse-mest-zeer-inter… )
