TREASoURcE is a four-year project (2022-2026) receiving funding from the European Union under the Horizon Europe research and innovation programme. TREASoURcE aims to initiate systemic change by developing systemic circular economy solutions in cities and regions for currently underutilized 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 experts in the field is expected to significantly increase product and material circulation in the Nordic and Baltic Sea Regions, see link
