The first Hub for Circularity in Greece
Turning circular innovation
into practice
Scaling circular solutions for cities, industry and regions
About THESEUS
THESEUS Hub4Circularity brings together industry, city authorities, and research organisations to co-create innovative circular solutions for managing water, energy, and materials. By combining practical experimentation with digital tools and cross-sector collaboration, the project supports Europe’s transition toward climate neutrality and more efficient resource use.
Based in the Attica region, THESEUS is establishing Greece’s first Hub for Circularity, a real-world setting where interconnected resource flows are tested, optimised, and demonstrated. Through pilot activities, stakeholder engagement, and capacity-building actions, the project shows how circularity can operate at territorial scale and generate value for businesses, municipalities, and communities.
By developing approaches that are scalable and transferable, THESEUS provides a framework that regions across Europe can adopt as they move toward systemic circular transformation.
Our mission
THESEUS aims to move circularity from isolated actions to coordinated regional practice. Its mission is to support a new model of Industrial-Urban Symbiosis, where waste, water, energy and material flows are treated as shared resources and translated into practical circular value chains. The project works to create lasting cooperation between public authorities, industry, utilities, research actors and communities, with benefits for resource efficiency, competitiveness and regional resilience.
How we work
THESEUS works by connecting five circular flows – textiles, urban waste and packaging, construction and demolition waste/glass, energy and water – with the tools and conditions needed to make them operational. This includes advanced sorting and processing technologies, digital mapping and matchmaking tools, governance and policy work, training, impact assessment and replication activities in Sweden and Norway. Together, these actions turn circular economy concepts into tested regional solutions.
Part of a European Movement
THESEUS is part of the Processes4Planet (P4P) partnership and the Hubs for Circularity (H4C) community under Horizon Europe, supporting the European Green Deal and Fit for 55 objectives for a climate-neutral Europe.
Bringing together 47 partners and 5 associated entities from 9 countries, THESEUS unites academia, industry, SMEs, authorities, and non-profits to establish Greece’s first Hub for Circularity and accelerate Europe’s circular transition.
Circular solutions
THESEUS develops and demonstrates circular solutions through five core pilots, each representing a critical symbiotic flow across materials, water, and energy. Together, these pilots show how advanced sorting, resource recovery, and Industrial–Urban Symbiosis can create scalable circular value chains in the Attica region and serve as a model for wider replication.
Enabling systemic circular transformation
THESEUS collaborates with industry, public authorities, researchers, SMEs, and communities to co-create and test circular solutions that enhance regional resilience. Through pilots, training, workshops, mentoring, and digital tools, we support territories in adopting practical pathways for Industrial–Urban Symbiosis.
Together, we strengthen the knowledge and capacities required to advance circular transformation across Europe.
