Reflections on the NextGen circular water solutions in the Athens final event

All results from the NextGen work packages and demo cases were presented, and Jos Frijns (NextGen project coordinator; NextGen – KWR) chaired the discussions on lessons learned. NextGen key messages:

• NextGen unlocked the potential of the circular economy in the water sector by demonstrating the recovery and reuse of water-embedded resources (such as water itself, energy, nutrients and materials) in 10 demo cases spread across different European regions in 8 countries (e.g. Demonstration cases – YouTube).
• NextGen demonstrated the benefits of circular water solutions in reducing water, energy and materials consumption, in the prevention of pollution to water ecosystems (rivers, lakes, coastal waters) and the environment (including reduction of greenhouse gas emissions), and in providing the added value of recovered resources to be used in other sectors (such as agriculture, energy, industry) to implement symbiotic approaches of the circular economy (e.g. 2-Assessment-of-NextGen-value-chains.pdf).
• NextGen has launched a Water Europe online match-making Water Europe Marketplace for products and services that showcase circular water technologies (e.g. struvite precipitation, anaerobic Membrane BioReactor, sludge pyrolysis, sewer mining), environmental and economic assessment tools (such as Life Cycle Assessment / Life Cycle Costing, Cost Efficiency Analysis, Quantitative Microbial Risk Assessment, CirculAR, Serious Game (e.g. toy town nextgen-serious-game), and best practices to implement circular economy solutions.
• NextGen 10 demo cases provide evidence-based knowledge on enabling framework conditions for the transition to a circular economy in the water sector (e.g. Sustainability), such as societal acceptability (e.g. of treated effluent reuse), circular value chains and business models (e.g. for recovered calcite), and supportive policy and regulations.
• NextGen policy recommendations (e.g. pdf) include the need for better aligned EU directives that incentivize circularity (such as Urban Wastewater Treatment Directive, Sewage Sludge Directive, Waste Framework Directive, Industrial Emissions Directive, Energy Efficiency Directive), improved clarity and transparency for the implementation of the Water Reuse Regulation, and Waste Framework Directive end-of-waste criteria that simplify the process of less costly routes to market for recovered resources.

All final deliverables will be available after review in due time Results – NextGen Water. To ensure the continued use and as part of creating a water in the circular economy marketplace, all our results from the demo cases, circular water technologies, products and tools are accessible on the Water Europe Marketplace, to which other projects such as ULTIMATE Water and B-WaterSmart will add their outcomes.
