Manure is a waste product that is produced on a large scale in agriculture. However, it contains valuable nutrients and valuable substances - not without reason has it always been used as a fertilizer. The Fraunhofer IGB is developing processes for the further use of liquid manure, in particular for the recovery of valuable ingredients such as phosphorus or nitrogen.
Further development of a sustainable process for phosphorus and potassium recovery from liquid waste through to market maturity
In the project "PhosKa-Demo" funded by the German Federal Ministry for Education and Research (BMBF), we have scaled up a sustainable process for the treatment of liquid manure and tested it in continuous operation. A fertilizer containing phosphorus and potassium that demonstrably enhances the properties of plants is recovered from manure by precipitation. The process concept had previously been developed as part of the EU-funded BioEcoSIM project.
