Use Cases
Demonstrating circularity in practice
THESEUS demonstrates its innovations through five targeted pilot use cases, each focused on a high-impact material, energy or water flow with strong circular potential.
Real-world pilots, replicable models
Together, the pilots integrate advanced technologies, system-level governance approaches, and cross-sector collaboration to test and validate scalable circular solutions in real-world conditions.
The pilots address context-specific challenges in Attica, while being developed as replicable and scalable models that can be adapted across European regions.
Through structured knowledge exchange and replication work with Malmö (Sweden) and Mo i Rana (Norway), the THESEUS pilots generate transferable insights and operational models for wider uptake.
The five pilots
Each pilot targets a distinct material, energy or water flow, integrating advanced technologies with governance and cross-sector collaboration.
Textiles
Advanced sorting, recycling and upcycling of textile waste.
Urban Waste / Biobased Materials & Packaging
Biobased packaging from municipal solid waste streams.
CDW, Industrial Waste & Glass
Recycled aggregates and recycled-content bricks, concrete/construction materials and insulation panels from CDW and glass.
Energy
Solar thermal, waste-heat recovery and energy-as-a-service.
Water
Water reuse, rainwater harvesting and sludge valorization.
Textiles
To redesign the textile value chain by integrating advanced sorting, recycling, and upcycling technologies that reduce waste and enhance circular reuse pathways.
Urban & Municipal Recycling Waste
To establish symbiotic flows for bio-based materials and packaging, integrating waste streams into high-value circular products.
Construction & Demolition Waste, Industrial Waste and Glass
To optimize the recycling and reuse of Construction and Demolition Waste (CDW) and glass waste, transforming it into new building materials.
Energy
To harness and optimize energy flows through innovative technologies and symbiotic systems, enhancing energy efficiency and promoting renewable energy integration.
Water
To enhance the sustainable management and valorization of water resources through decentralized and centralized solutions, promoting circular water use and mitigating water-related challenges.
From Attica to a European circular network
Grounded in the Attica region and aligned with the Processes4Planet (P4P) partnership, the THESEUS pilots feed a pan-European ecosystem, with replication areas in Sweden and Norway carrying the solutions to new regional contexts.
