ReNu2Farm aims at increasing recycling rates of the plant nutrients Nitrogen (N), Phosphorus (P) and Potassium (K). P and K are limited and finite resources, and the production of N fertilizers is energy intensive. Despite recovery technologies having been developed, the use of recycling-derived fertilizer products by farmers is limited until now. The project will tackle the barriers limiting recycling-derived fertilizer use.

Nutrient Recycling – from pilot production to farms and fields.

Selected project countries are Ireland, United Kingdom, Germany, Netherlands, Belgium and France. Within these countries, regions with nutrient shortage and surplus can be distinguished. Possibilities for exchange of recycled nutrients between regions will be explored and producer-consumer collaboration developed.

Upcycling nutrients in surplus regions to mineral fertilizer quality (according to farmers’ needs) will create demand in nutrient-demand regions in NWE. By developing transnational markets and by communicating policy advice, market barriers will be reduced. This will result in replacing mineral fertilizer amounts with recycling-derived products by the end of the project (-54,000 t N, -4,000 t P, -60,000 t K).

The 3 largest waste streams (sewage sludge, food waste and manure) will be considered and in an enterprise-academia cooperative monitoring processes, 20 producers will succeed to improve 17 recycling-derived fertiliser products' properties according to end-user needs. Development of transnational trade chains will facilitate 20 enterprises to introduce new-to-market recycling fertiliser products. In bottom-up cooperation with farmers, 8 farm enterprises will host demo fields and thus receive training. The knowledge transfer extents with demo events to members of 10 farmers’ organizations. Farmers knowledge lack barrier is decreased and with transnational trade chains being developed, raw material nutrient use decreases.

Due to communication to stakeholders (producers and farmers) (publications in magazines/ internet; workshops) 2% (-108,000 t N, -8,000t P, -120,000t K) of mineral fertilizer amounts will be replaced with recycling-derived products after 5 years and 6% (-324,000t N, 24,000t P, 360,000t K) after 10 years. Farmers’ organizations and fertiliser producer branch organisations as associate partners ensure long term implementation.
