Closing the gap between fork and farm for circular nutrient flows (P2Green)

Abstract:

P2GreeN will foster a paradigm shift, from a linearly organised resource and nutrient system within the agri-food supply chain, towards a circular material flow system between urban and rural areas thereby restoring the coupling of the water-agri-food system using a holistic symbiotic resource management approach following the 3R principle “Reduce, Reuse, Recover”. P2GreeN willtherefore develop new circular governance solutions for the transition from fork to farm to halt and eliminate N & P pollution by connecting blue urban with green rural infrastructure, focussing on circular nutrient flows of nitrogen (N) and phosphorus (P). This will be done trough implementation and demonstration of innovative N & P recovery solutions for the utilisation of human sanitarywaste from urban settlements and its conversion into safe bio-based fertilisers for agricultural production in three pilot regions (P2GreeN pilot regions) on a north-south trajectory from the Baltic Sea region via the metropolitan area of Hamburg-Hannover to the region of Axarquia in Southern Spain. This approach will be extended to follower region in Italy, France, Greece and Hungary
