TREASoURcE.Systemic circular economy solutions
Territorial and regional demonstrations of systemic circular economy solutions for key value chains — and their replication across the Nordic and Baltic Sea Regions.
Why TREASoURcE?

TREASoURcE aimed to initiate systemic change by developing circular economy solutions in cities and regions for previously underutilised or unused plastic waste, end-of-life electric vehicle batteries and bio-based waste and side streams.
Implementing these solutions together with companies, societies — including citizens, consumers, communities and regional actors — and field experts significantly increased product and material circulation in the Nordic and Baltic Sea Regions.
The combination of cities and regions enabled large reach and bigger impact, boosting the replicability and scalability of the solutions. They helped regions decouple from fossil virgin resources, increased resilience, decreased greenhouse gas emissions and contributed to climate-neutral economies.
TREASoURcE Replication Handbook
A practical, open-access guide compiling the project's methods, tools and lessons learned for developing circular economy solutions in cities and regions. It supports replication of the TREASoURcE approach across the Nordic and Baltic Sea Regions and beyond.

Watch the project video to learn how cities and regions across the Nordic and Baltic Sea Regions developed systemic circular economy solutions together with companies, research organisations and citizens.

Trash into Treasure
The TREASoURcE podcast, Trash into Treasure, explores the real-world applications, challenges and cultural shifts driving circularity forward. Each episode dives into a different piece of the circular puzzle — from biowaste and plastics to batteries and community action — showing how innovation, collaboration and everyday choices can build a more sustainable world.
Listen to episodesCLIC's role: communication, partnerships & strategy
CLIC led the communication and dissemination activities (WP8) and the Symbiotic B2B partnerships SE-DEMO task, and contributed to identifying regulatory barriers and building circular economy strategies (WP1).
Communication & dissemination
CLIC led the communication and dissemination activities — sharing results and engaging stakeholders across the targeted sectors in industry and research.
Symbiotic B2B partnerships
CLIC led the Symbiotic B2B partnerships task, building on its wide networks across the CLIC cluster and relevant Finnish stakeholders.
Regulatory barriers & CE strategies
CLIC contributed its experience from previous projects in identifying regulatory barriers for sustainable development and building circular economy and regulatory strategies.

Circular Cities and Regions Initiative

TREASoURcE was part of the European Union’s Circular Cities and Regions Initiative (CCRI) that sought to support the implementation of local and regional circular economy solutions. The CCRI is part of the new European Circular Economy Action Plan adopted in March 2020 and also provides a local contribution to the implementation of the European Green Deal and the European bioeconomy strategy. It places cities and regions at the heart of the EU’s green transition. TREASoURcE built close collaboration and synergies with the CCRI and other circular economy projects and initiatives.
