Deliverable D1.5 - New approaches and best practices for closing the material cycles within symbiosis cluster

The EU Horizon 2020 ULTIMATE promoted circular economy concepts within theframework of water smart industrial symbioses. It focused on industrial wastewaterstreams as resource for water, energy and material recovery. ULTIMATE developedand demonstrated 24 circular economy related technologies. In six out of nine casestudies (i.e.; N. Prinsenland, Rosignano, Nafplio, Karmiel, Tain and Kalundborg),symbiosis network in regional area were demonstrated towards the implementation ofdifferent material recovery routes, which included recovery of nutrients from industrialwastewaters, use of by-products of local industries for wastewater treatment, recoveryof high-value products (e.g.; antioxidant, polyphenols, sulphurs, metals). In addition, inthis document are also reported results related to the use of innovative fluorescencesensors to monitor the removal of organic micropollutants during quaternarytreatments of wastewater to comply with recent EU regulations on urban wastewatertreatment and reuse. Recovery of nutrients from industrial wastewater Solutions for nutrients recovery were investigated in the ULTIMATE case studies in theNetherlands (Nieuw Prinsenland), Lleida (Spain), Tain (Scotland). Recovery of industrial by-products and test of innovative fluorescence sensors Investigations about the possibility to use industrial by-products for wastewatertreatment were accomplished in the Italian case study of Rosignano. Recovery of added values compounds from industrial wastewater Technological solutions for the recovery of high-value compounds from wastewaterwere investigated in the cases study in Greece, Israel, France and Denmark.
