With the amendment of the EEG and the new fertilizer ordinance, farmers are faced with considerable challenges. In the future, biogas fermentation residues will have to be increasingly stored and transported, resulting in increased costs. The aim of this project is to produce two new high-quality products from these fermentation residues and to demonstrate this with the aid of a pilot plant. These new products are the approved slow-release fertilizer struvite and activated carbon or high-performance carbon. Struvite serves to close the nutrient cycle and is a concentrated mineral fertilizer. Moreover, the storage and transport of the fertilizer are not problematic. Activated carbon is in great demand on the market, so additional revenue generation is promising. In the long term, another focus is on obtaining even more valuable high-performance carbons for electricity storage. These are indispensable for the expansion of electromobility, as the fossil graphite currently used for electricity storage is limited and is only mined in a few countries around the world.
