Relevance for Circular Systemic Solutions

The TREASoURcE Replication Handbook focuses on three key value chains: plastic waste, end-of-life electric vehicle (EV) batteries, and bio-based side and waste streams.


It engages a diverse range of stakeholders, including municipalities, businesses, farmers, NGOs, educators, and citizens, aiming to foster systemic circular economy (CE) solutions across urban and rural settings in the Nordic and Baltic Sea regions. For cities and regions, the Handbook is a guide that offers guideline practices to replicate and transfer demonstrations of circular economy key areas.


For instance, it provides guidance on optimizing recycling technologies for plastics, evaluating second-life applications for EV batteries, and creating marketplaces for bio-based materials. The insights and recommendations from the Handbook are instrumental in developing Circular Solutions by showcasing best practices and use cases.


The Handbook supports the mapping, design, and implementation stages of CE initiatives.
