Periodic Reporting for period 2 - REDOL (Aragon's REgional Hub for circularity: Demonstration Of Local industrial-urban symbiosis initiatives)

Berichtszeitraum: 2024-06-01 bis 2025-11-30

Zusammenfassung vom Kontext und den Gesamtzielen des Projekts

The primary goal of REDOL is to advance the technological, managerial, economic, and social capabilities of EU Hubs for circularity. This will be achieved by demonstrating innovative and sustainable methods to valorise Solid Urban Waste (SUW) flows using Industrial-Urban Symbiosis (I-US) approaches. The ultimate aim is to produce recycled secondary materials that can be used to manufacture high-value circular products. Within these goals, they were defined 4 specific objectives which will facilitate the accomplishment of the primary goal:
Specific Objective 1: To develop and demonstrate novel management systems and processing technologies for the valorisation of SUW to be used as feedstock for other sectors and/or across value chains.
Specific Objective 2: To obtain recycled secondary materials from SUW ready to be fed in downstream processes for the further production of circular products, closing the production loop.
Specific Objective 3: To enable the achievement of a zero SUW landfilling approach in Zaragoza by accomplishing 55-100% recycling rates in REDOL value chains while creating new sustainable economic activity in the Aragon region.
Specific Objective 4: To establish a roadmap for the implementation of REDOL solutions in other urban environments and industrial areas, tackling technical and non-technical barriers.

Arbeit, die ab Beginn des Projekts bis zum Ende des durch den Bericht erfassten Berichtszeitraums geleistet wurde, und die wichtigsten bis dahin erzielten Ergebnisse

During the second 18 months:

WP1 (Management/coordination)
Coordinator ensured admin/technical support, EC reporting and interim payments. Quality via peer review, corrective actions, risk/conflict management and DMP. Updated RRI delivered (D1.4).

WP2
Completed in RP1; baseline for follow-up work.

WP3 (Sorting and classification)
Final design/manufacturing/integration/testing (D3.1 D3.2). Smart bin validated (>85% accuracy). Industrial-speed HSI for real-time MMPP classification. Integrated CDW robotic line (pre-processing, HSI models, robot, gripper, calibration, PLC/HMI). Upgraded textile sorting (NIR/HSI+RGB) and optimised elastane removal (high-purity polyester). Commissioned mobile paper/cardboard sorter and PCB extraction/classification prototype (WP6-ready).

WP4 (Recycling and valorisation)
Feasibility confirmed (D4.1 D4.2). Composite solvolysis benchmarked (microwave best). Multilayer packaging routes validated by typology. CDW/industrial routes assessed for cement/concrete. Textile glycolysis/repolymerisation delivered ~450 kg rPET. DES leaching for PCB metals assessed (selectivity, saturation/kinetics).

WP5 (Digital platform, analytics and LCA/LCC)
Deployment/integration (D5.1 D5.2). DSP final release (expanded CIM + 5 bundles). Zaragoza fill-level forecasting and routing optimisation (KPIs/CO2). Harmonised LCA/LCC baseline; I-US assessment services pilot-ready.

WP6 (Value-chain redesign and pilot preparation)
Common methodology and redesigned value chains agreed (D6.1); integration planning, scalability and bottleneck mitigation for RP3 demos.

WP7 (Frameworks, policy/replication groundwork)
Co-creation for circular hub/cluster, EU regulatory screening, and replicator baselines/stakeholder mapping.

WP8 (Business and dissemination)
Business models refined; Zaragoza collaboration setup piloted; dissemination activities delivered.

Fortschritte, die über den aktuellen Stand der Technik hinausgehen und voraussichtliche potenzielle Auswirkungen (einschließlich der bis dato erzielten sozioökonomischen Auswirkungen und weiter gefassten gesellschaftlichen Auswirkungen des Projekts)

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.
