Every day, vast amounts of nutrient-rich wastewater disappear into urban sewers, while farms relying on conventional fertilisers struggle to maintain yields and cope with growing water scarcity. What cities have in excess, agriculture often lacks. Bridging this gap is emerging as a practical route to cleaner water, stronger food systems and a more circular European economy. 
 
This is exactly the challenge the P2GreeN project is tackling – and we are proud to share that its results have now been featured by CORDIS, the European Commission’s research results service, in a new Results Pack on circular solutions in European cities and regions. 
 
P2GreeN is showing how cities and rural areas can reconnect resource flows by transforming wastewater, urine and faeces into safe agricultural inputs. Three pilot regions demonstrate what this looks like in practice – each shaped by a different local pressure, but all pointing to the same circular logic. 
 
La Axarquía, Spain – Water scarcity puts agriculture, residents and tourism in competition. Treated wastewater is filtered, disinfected and adjusted via a smart fertigation tool to irrigate mango and avocado orchards while supplying nutrients. 
 
Gotland, Sweden – Seasonal tourism strains wastewater systems and drives nutrient releases into the Baltic Sea. Urine collected at festivals is stabilised and processed into dry fertiliser for agricultural use. 
 
North German Plain, Germany – Nutrient losses from agriculture and wastewater affect groundwater and rivers. Dry separation toilets at festivals and public spaces enable urine to be converted into liquid fertiliser and faecal matter to be composted into soil improver.
