Manure processing as a pathway to enhanced nutrient recycling by Sari Luostarinen, Elina Tampio, Johanna Laakso, Minna Sarvi, Kari Ylivainio, Kaisa Riiko, Katrin Kuka, Elke Bloem and Erik Sindhöj

The need to introduce new nutrients into the current demand from mineral resources could be reduced significantly via nutrient recycling. The most significant recyclable material is animal manure which is traditionally used as a fertilizer. However, due to segregation of crop and animal production, manure is often regionally concentrated so that its nutrients may be available in excess to the region’s need. To enable regional nutrient reallocation, manure processing to various end-products could be used. In this report the advantages and challenges of manure processing are discussed and several processing technologies introduced.
