Nutrient Recycling – from Pilot Production to Farms and Fields
Nowadays in North-West Europe 5.4 Mt N and 0.4 Mt P of mineral fertilizers are spread on agricultural land. Almost 100% of mineral fertilizers are imported into EU and only ca. 5% of total fertilizer amount spread in the regions are based on organically recycled materials. Phosphorous and Potassium are limited resources, and the production of N-fertilizers is energy intensive. Despite available recovery technologies, the use of recycling-derived fertilizer products in farming is limited.
