BEEFCOMPOST: Optimisation of the fattening cattle manure composting process
BEEFCOMPOST: Optimización del proceso de compostaje de estiércol de vacuno de carne
Context
As its name suggests, the ultimate goal of the BEEFCOMPOST project is to find a use for manure from cattle
fattening farms apart from direct application to fields.
In the current situation, the conditions under which manure can be applied directly to fields will be
increasingly limited. For this reason, and within the context of the circular economy (using better what we
already use) the aim is to allocate a proportion of cattle manure to producing high quality compost, to enable
nutrients to be exported to other more remote agricultural areas in the form of organic fertilisers.
Objectives
There are 2 specific objectives:
a) Reduce the tonnes of manure produced per stall and per year.
b) Improve the quality of fertiliser produced by composting manure.
The data will also be used in the future to improve estimates of the tonnes of manure produced
per stall per year, the effects of its storage and the changes during the year.
Emissions of ammonia and greenhouse gases
will also be reduced:
a) Because it reduces the tonnage, the proposed strategy also reduces the excretion of nitrogen in
manure.
b) As it is an aerobic process, composting reduces methane emissions.
c) The proposed strategy for improving the quality of composting seeks to retain the N content, thereby
reducing ammonia emissions.
Objectives
Objetivos principales
- Reducir las toneladas producidas de estiércol por plaza y año.
- Mejorar la calidad del fertilizante generado mediante el compostaje de estiércol
Los datos del proyecto servirán para estimar mejor las toneladas producidas de estiércol por plaza y año, el efecto de su almacenamiento i su evolución durante un año.
También se reducirán las emisiones de amoníaco y de gases de efecto invernadero ya que:
- Reducir el tonelaje reduce la excreción de nitrógeno en las deyecciones.
- El compostaje, al ser un proceso aerobio, reduce las emisiones de metano.
La estrategia para mejorar la cualidad del compostaje busca retener el contenido de N, con el que se reducen las emisiones de amoníaco.
Activities
When these strategies were applied, there was an improvement in the maintenance of high temperatures, the material in each pile was more homogeneous, and the material contained less moisture, with lower speeds in the piles containing crushed material compared to non-crushed material for the same amount of wetting. As a result, the piles subject to the most wetting (only the amount was increased, but not the frequency) are more biologically active. This is reflected in a greater reduction in the mass of matter (weight reduction of 0-10% and a 38-64% reduction in the low irrigation strategy).
Activities
Con estas estrategias se ha observado una mejora en el mantenimiento de temperaturas elevadas, mayor homogeneidad del material en cada montón y una reducción de la humedad del material con menor velocidad en las pilas con material triturado en comparación con el material no triturado, para la misma cantidad de riego.
Como consecuencia, en las pilas con mayor humectación (solo se aumentó la cantidad, no la frecuencia), hay una mayor actividad biológica que se refleja en una mayor reducción de la masa de materia (reducción de peso de 0-10% y 38-64% de la reducción con la estrategia de poco riego).
