with alkali salt (NaOH). BioPOL was tested as a flocculant, and showed potential for replacing petro-chemical polymers in sludge treatment. This would enable use of a renewable product derived from the sewage itself for this process, and would avoid spreading of the polymer flocculants. The organo-mineral fertiliser produced from treated sewage sludge showed good agricultural performance, with nutrient plant availability contributing to crop growth, as well as increasing soil carbon (positive for nutrient plant use, water retention and so drought resistance, and for soil structure thus reducing soil loss and erosion). Contaminant levels measured were considered not problematic. However, difficulties were encountered in producing pellets of the organo- mineral product with sufficient density and physical resistance for use with farmers’ fertiliser spreading equipment. The LIFE ES-WAMAR project aimed to improve the 1-10-2006 31-3-2011 LIFE+ Arturo management of pig slurry so as to minimise its Dauden environmental impact by introducing an integrated Ibanez management model for the processing and distribution of swine of pig slurry. It sought to match the needs of arable waste farmers for fertilisers with the need of pig farmers to based on dispose of their slurry appropriately and economically innovative through collective action. It thus planned to: reduce soil, technology: water and air contamination - especially nitrates from a non-point sources – in areas around pig farms; and maximise nutrient recycling through the valorisation of project the pig slurry on arable land. The management model set in also aimed to improve economic efficiency and minimise Aragón the energy requirements of the waste management. The (Spain) project planned to demonstrate the feasibility and sustainability of the correct integrated management model of swine waste at three sites in Aragón: Tauste, Maestrazgo and Peñarroya. It thus showed that the same model adapted to local circumstances could respond
