Decentralized treatments for resource recovery from domestic wastewater

Run4Life partners Agualia, LeAF, DeSaH and WE&B organised a workshop on the 24th of June at the 5th International Conference on Ecotechnologies for Wastewater Treatment (EcoSTP 2021, online). They introduced the change in wastewater management proposed by the Run4Life project, based on the decentralised treatment of segregated flows of wastewater and kitchen waste. Furthermore, the crucial aspect of social acceptance of the decentralised treatment concept, innovative technologies and use of the recovered products were presented. Challenges and opportunities of this new approach were discussed with the audience in an interactive way. The presentation about social acceptance was followed by an interactive whiteboard session in which participants were invited to express their ideas regarding decentralised resource recovery. Examples of concerns shared on the board are worries about the quality (health risks, contaminants) and quantity (drop in the ocean) of the recovered fertilisers, and the management of the applied treatment and recovery technologies. Highlighted positive aspects were the use of existing technologies that can bring us back to a sustainable nutrient cycle, reduced use of artificial fertiliser and effects of increased awareness about water and wastewater when it is applied at household level.
