| contents | <p><span>P2GreeN, a four-year Horizon Europe project focusing on closing the chain between farm and fork for cyclical nutrient flows. It will test and adapt the use of human sanitary waste to produce safe, bio-based fertilizers for agriculture, which will replace fertilizers of mineral origin. It is testing three innovative nutrient recycling technologies in three pilot sites in Germany, Spain and Sweden. The pilot sites have been carefully selected as they demonstrate the link between urban (fork) and rural (farm) communities. At the same time, the possibility of replicating and scaling up these technologies in other EU countries such as Italy, Greece, Hungary and France is being explored. The aim is to adapt each pilot technology to a specific geographical area based on its characteristics and needs.</span></p> <p><span>In Greece, three feasibility studies will be carried out, one for each P2GreeN pilot technology, to verify the feasibility of implementation at national level. The first solution separates valuable urine at source using a urine diversion toilet or urinal and the final fertilization product is in pellet form. In Greece, a company renting portable toilets has been identified as a point of application, as only the replacement of the toilets is required without any significant deviation to the daily operation of the business. The second solution utilizes a urine diversion toilet, and the final fertilization product is in liquid form. It is installed in building complexes and requires the existence of a second </span><span>sewerage system that collects only the urine and treats it on site in an ancillary area of the building. It is therefore considered to be economically advantageous in buildings under construction or undergoing radical renovation, such as the Roussopoulos building of the Agricultural University of Athens. Finally, the third solution utilises the secondary treatment effluent of a municipal waste treatment plant to produce a nutrient-rich water for irrigation. The biological treatment of Karditsa is a typical case due to its proximity to agricultural holdings.</span></p> <p><span>At the same time, the application of these technologies is examined in the light of the existing legislative framework of the European Union and Greece, which regulates the management of these materials at various levels, from raw material to final product. The European Union is legislatively promoting the transition towards a circular economy, enhancing recycling and reuse of resources, but there are still gaps and challenges in the full implementation of circularity principles in individual waste streams.</span> </p> |
