Project description

The aim of the project is to develop a procedure for slurry processing for farms, with which slurry and manure can be used to produce transportable fertilizers. For this purpose, farm manure is not treated as usual after, but before addition to the biogas plant (alternatively during use) so that as much nitrogen, phosphate, and water are extracted as possible. Through the production of fertilizer concentrates, transport costs are reduced by dehydration and use of locally produced manure. Likewise, gas production is to be increased by optimizing the substrate properties, and the increased use of manure and slurry in the biogas process will reduce the cultivation of maize for energy. For the testing and implementation of this innovation, farmers are involved in the project whose operations differ with regard to substrate composition as well as to agricultural priorities. As a result, improvements are expected for the environment, agriculture, and sustainability of biogas plants.
