"DECISO - DEVELOPERS OF CIRCULAR SOLUTIONS” aims to support the delivery of services to induce investments projects for developing circular economy at local and regional scale in the following regions: Hamburg. Northwest Germany, West Macedonia, Alentejo. This is in line with implementing the European Green Deal and the EU circular economy action plan. DECISO will accompany the actions aiming to provide assistance for promoters in the development of financial schemes/programs for projects on Circular Economy, based on the concept of Circular Economy Ecosystem (CEE), which implies mobilizing local stakeholders and, when necessary, citizens, and scaling up the results from the local, to the national and European levels. The CEE approach will make it possible to deal with economic, organizational and cultural change through systemic solutions that involve all the players in the value chain of an asset and all those who can influence, even indirectly, its value. This approach also allows reducing risks for investors, because ecosystems with all their key factors, including geographic location, cultural factors and institutional support, actively help an innovation become successful. Since the paradigm of the Circular Economy Ecosystems can be declined in different ways, based on the objective of the initiative, the local context, the type of actors and the sector, the DECISO approach will be implemented in different local contexts and topics in order to produce guidelines that can facilitate the replicability of the initiatives put in place considering all the technical, economic, legislative, and social factors that can determine the success or failure of the initiatives.

Contributing to the CCRI project portfolio, CisWEFE-NEX will demonstrate the implementation of a circular systemic WEFE Nexus, an innovative, fully integrated, & sustainable approach applying the principles of circular economy for closing loops in the key value chains of food, water & nutrients in severely water stressed regions: 1. Water: - A net positive freshwater balance to the water cycle (JRC 2021) will be achieved through combining olive mill wastewater reuse (as a co-product from biophenols extraction) with saltwater desalination at scale without using fossil fuels for use as drinking & irrigation water. - Waste streams from desalination (brine & bitterns) will be repurposed in nature-based solar saltworks as table & Epsom salt, made possible because of zero chemical use in the desalination process. 2. Energy: - Cutting-edge renewable energy technologies will be developed & demonstrated to achieve a net-zero direct fossil GHG emissions process. - Agri-photovoltaics (crops under PV panels) and biogas from advanced (ultrasonic cavitation assisted) anaerobic digestion fed from olive mill & other biowastes. 3. Food: - Innovative nature-based techniques will be demonstrated to enable truly sustainable, healthy, and fresh food & seaweed (containing bioactive compounds for pharma use) production at scale. - Saltwater integrated multi-trophic aquaculture (free of growth hormones, antibiotics, synthetic fertilisers, & preservatives). - Regenerative agriculture (organic permaculture reusing precious water & nutrients) and extractive reuse of biophenols from olive mill waste as bioactive products of very high nutri-pharmaceutical value. 4. Ecosystems: - Monitoring of traditional & emerging (micro)pollutants using cutting-edge analytics will prevent harmful impacts on the environment & food grown from it with predictive alerts & remedies through a mobile controlled cavitation unit providing (waste)water treatment services (advanced oxidation processes, disinfection).
