During RP2, REDOL delivered pilot-ready technical results with clear potential to increase circularity, reduce environmental impacts and improve resource efficiency across the targeted value chains. Key outcomes include integrated SUW sorting solutions (smart bin and HSI-based classification) validated under realistic/industrial conditions, enabling higher capture rates and purity of separated fractions, and robotics-supported separation for CDW and other streams. Advanced recycling routes were validated for complex wastes beyond conventional mechanical recycling, including green solvolysis for composites, tailored delamination/compatibilisation pathways for different multilayer packaging typologies, and feasible valorisation options for selected CDW/industrial fractions in cement and concrete. Textile chemical recycling was scaled through glycolysis and repolymerisation, delivering ~450 kg of recycled PET from purified BHET, while DES-based processes for PCB metal recovery clarified selectivity and saturation behaviour to guide optimisation. In parallel, the REDOL Data Sharing Platform reached final release (expanded CIM and operational bundles), enabling governed data ingestion and sharing, complemented by forecasting and routing optimisation services for municipal collection.
To ensure uptake and success, priorities are: (1) continued WP6 demonstrations to prove robustness, throughput and cost under real operational conditions; (2) end-user qualification of recycled outputs with stable specifications and long-run trials; (3) supportive regulatory/standardisation frameworks (e.g. acceptance criteria for secondary materials, construction products, recycled polymers); (4) integration of the digital platform with existing IT systems, clear data governance and IPR arrangements; and (5) financing and commercialisation planning to bridge from pilot to procurement and replication.
