THESEUS H4C at the Arctic Cluster Team Partnership Event: Strengthening Circular Value Chains in the Arctic Date December 10, 2025 Location Norway Last week, THESEUS Hub4Circularity participated in a partnership event organised by the Arctic Cluster Team (ACT), reinforcing the project’s engagement with Arctic regions and its role in supporting circular, low-carbon industrial transitions across […]

Decarbonising Urban Heating and Cooling Through Energy Symbiosis The Energy Symbiotic Flows pilot addresses the decarbonisation of urban heating and cooling systems by demonstrating how renewable and circular energy technologies can be integrated at district scale. The pilot focuses on transforming siloed, fossil-based urban energy infrastructures into flexible, digitally managed, and low-carbon systems operating in […]

From foundations to development: THESEUS H4C releases Newsletter Issue 2 THESEUS H4C Newsletter Issue 2 is now available.The second edition highlights how the project is moving from foundational design toward development and pilot preparation across materials, energy and water. It presents progress on governance frameworks, digital infrastructure, value chain mapping, enabling technologies, and pilot-facing solutions […]

Closing the Loop on Construction Waste Through Industrial Symbiosis The Construction and Demolition Waste and Industrial Waste Symbiotic Flows pilot addresses one of the most material-intensive and carbon-intensive waste streams in cities: Construction and Demolition Waste (CDW), together with associated industrial residues such as metals and glass. The pilot demonstrates how urban “rubble” can be […]

From Urban Textile Waste to High-Value Circular Materials The Textiles Symbiotic Flows pilot addresses one of the most complex and underperforming urban waste streams by transitioning from fragmented, manual textile sorting to an integrated, automated, and high-value circular processing system. The pilot focuses on transforming post-consumer textiles from an urban waste management burden into a […]

New scientific publication on energy system modelling in Greece A new scientific publication in the journal Energy Strategy Reviews explores how energy system modelling has been applied to the Greek energy sector since the ratification of the Paris Agreement. The study, co-authored by researchers from the THESEUS Hub4Circularity, provides a systematic review of modelling approaches used […]

THESEUS transforms a school rooftop into a living classroom for circular water management On 26 February 2026, the 21st Primary School of Athens “Lela Karagianni” became the setting for a hands-on sustainability activity organised within the framework of the THESEUS Hub4Circularity project.Led by the Sanitary Engineering Laboratory of the National Technical University of Athens (NTUA), […]

Upcycling Municipal Waste into Circular Packaging Solutions The Biobased Materials and Packaging Symbiotic Flows pilot focuses on one of the most critical urban material streams: mixed municipal and packaging waste. The pilot addresses the structural inefficiencies of current recycling systems by transforming contaminated urban waste into high-quality, circular packaging materials with recycled content through advanced […]

THESEUS H4C presents digital pathways for regional circularity, MFA projections and Digital Product Passports THESEUS H4C hosted a dedicated session within the Hubs4Circularity Community of Practice Webinar on “Regional Matchmaking, MFA & DPP for sophisticated waste valorization and upcycling: Approaches and EU Project Experience from THESEUS.” The webinar brought together participants interested in circular economy, […]

Enabling Circular Water Management at Urban and Regional Scale The Water Symbiotic Flows pilot demonstrates approaches for managing urban water and wastewater flows, as circular urban resources. The pilot integrates decentralised and centralised solutions to recover water, nutrients, and energy, supporting climate resilience and long-term sustainability in urban and peri-urban environments.The problemUrban water systems across […]
