D2.3 – Report including environmental, social and farming dimensions of impacts associated with the pilots (Factsheet)

Year: 2026
Type: article
Abstract: These factsheets summarise the impact assessment results of the P2GreeN project for two recycled nitrogen fertilisers made from separately collected human urine: Granurin, tested in the Swedish pilot region of Gotland, and Aurin, tested in the North German Plain pilot region. They are based on Deliverable D2.3 “Report including environmental, social and farming dimensions of impacts associated with the pilots”, produced under Task 2.3 (Impact assessments) of Work Package 2, led by the Natural Resources Institute Finland (Luke). Each factsheet combines measured results from multi-year field trials and product and soil analyses with environmental life cycle assessment (LCA), social life cycle assessment (S-LCA) and economic modelling. Each product is compared with conventional mineral fertiliser and wastewater treatment as the reference system. The factsheets cover agroecological impacts (yield, crop quality, soil health, heavy metals and pharmaceutical residues), nutrient recovery, production and farm-level costs, climate, eutrophication and acidification impacts, and potential social risks in the supply chain. Key findings show that both fertilisers can replace mineral nitrogen fertiliser without reducing yields, while greatly lowering net climate impact (by 85% for Granurin and 99% for Aurin) and largely offsetting eutrophication impacts. The main trade-offs are high pilot-scale production costs, acidification impacts close to those of mineral fertiliser, and supply-chain social risks linked to the urine stabiliser (Granurin) and electricity use (Aurin). Each factsheet ends with targeted recommendations for farmers, technology providers, and policymakers and municipalities.
