About the project

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 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 experts in the field is expected to significantly increase product and material circulation in the Nordic and Baltic Sea Regions.



Demonstrated environmental, social, economic and political impacts of the systemic circular economy solutions (Circular plastics, batteries, and biobased side and waste streams) in the Nordics


Replicated locally tailored systemic CE solutions in the Baltics, Poland and beyond


Inclusive and just transition to CE for all supported by high level cooperation with all relevant stakeholders


TREASoURcE is expected to have significant environmental, social, economic and political impacts, supporting an inclusive and just transition to circular economy for all.

Efficient management and valorisation of local resources

TREASoURcE territories share together an important natural ecosystem, the Baltic Sea, which is subject to unnecessary logistics as e.g. plastic waste is exported and shipped due to lacking waste management infrastructure. Proper management of biobased side and waste streams and circulating nutrients is important to protect the Baltic Sea from eutrophication, which is a major environmental issue in the marine ecosystem. TREASoURcE optimises nutrient recirculation and flows, raw material use and limiting the need for land and energy use connected to TREASoURcE’s approach in both production and waste management as well as circular business models.

By 2035, TREASoURcE will have contributed to 9,5 Mtonnes of GHG emission savings

TREASoURcE focuses on greenhouse gas (GHG) emission reduction throughout the whole project, tackling streams that are currently not circulated and producing added value materials and products for new loops. The focus is especially in urban-rural regions, since it is common that these streams could be circulated but they are produced in a decentralized manner. Greenhouse gas emissions will be reduced throughout the project activities and further in widespread exploitation of the project demonstrations and other practices.

Systemic circular economy solutions for sustainable growth of economies, sectors and regions

Local and regional economies and actors have a big role in TREASoURcE, the demonstrations will formulate new value chains and business opportunities reaching through the urban-rural settings. TREASoURcE will demonstrate at least 8 new circular business models that will be disseminated to primary producers (agriculture) and CE entrepreneurs (reuse, refurbishment) who can exploit the new business opportunities. TREASoURcE’s CE business opportunities and new employment will support the European future wealth and competitiveness, and as an immediate impact, help bounce back from the effects of COVID-19. Circulating the targeted side and waste streams will provide security to the value chains and minimize investment and business risks by ensuring local supply of raw materials.

WP2 - Understanding key stakeholders’ incentive and roles

Work package 2 builds on existing value chain networks in order to establish and strengthen stakeholder engagement structures supporting circular economy transition in TREASoURcE cities and regions. Involving a broad range of stakeholders, the idea is to build long-term cross-sectorial cooperation.


  • Achieve transparent decision-making processes and transitions to CE supported by relevant stakeholders.
  • Strengthen the decision makers capability of enabling CE.
  • Learn from stakeholders and understand their perspectives, perceptions and positions in the CE transition.
  • Build knowledge and stakeholder capacity to ensure they understand the benefits of CE and can participate in implementing CE on different stakeholder levels.

Main activities

  • The structures for stakeholder engagement will be established by setting up cross-sectorial task forces in 3-4 geographical areas. The aim is to cooperate with a broad range of stakeholders.
  • Once the stakeholder cooperation established, concrete cooperative actions will be carried out through five different demonstrations, including activities such as workshops for consumers and industry actors, hackathons, fixing workshops, seminars, procurement recipes, and larger cultural and sports events.

Main outcomes

Work package 2 will develop, test and showcase best practices for engagement and cooperation with consumers, citizens, and communities regarding circular economy. This will result in reports, guidance booklets, procurement recipes, and a range of learning materials supporting CE training.

WP7 - Sustainability Assessments

Work package 7 provides metrics, tools, and data for assessing the sustainability of TREASoURcE solutions.


  • Identify in secure way solutions that are ill-suited from sustainability perspective.
  • Identify critical success factors and potential risks of existing or planned circular systems.
  • Generate and document indicator results for stakeholders to enable opinion formulation and informed decisions making.
  • Provide guidance and lessons learned to support a sound transfer and replication of successful circular systems.

Main activities

  • Developing a framework for sustainability and circularity assessment that integrates impact indicators for sustainability (in a social, environmental, and economic dimension), performance indicators for circularity, and also context indicators.
  • In parallel, an assessment toolset will be created, in close coordination with project stakeholders. The toolset will be tailored to expert and non-expert audiences and is to be further complemented by a guideline for data collection, data curation and data maintenance.
  • With the framework, the work package will conduct an analysis of the three main project cases: Circular plastics value chain sustainability assessment, Batteries reuse and recycling value chain assessment, and Biobased waste streams for biogas and fertilizers assessment.

Main outcomes

Work package 7 expects three main outcomes. For one, an assessment framework for sustainability and circular economy of circular systems. Second, expert and non-expert tools and a data pool and guideline for project-specific assessments. Third, applied sustainability assessment of the key value chains in the project. Each of these outcomes will also be captured in an extensive report.

Expected impact

The metrics, tools, and data provided by this work package will help understand whether and how far circular economy systems are indeed sustainable, and thus can be applied for finding best ways to transfer and scale up new and existing circular systems. The project outcomes are applied to existing regional value chains, delivering results and supporting the transferability of circular systems of key value chains in the EU. Assessment results will guide initiatives for improved circularity, efficient management and the valorisation of local resources, leading to e.g. the reduction of GHG emissions. It is expected that by 2035, TREASoURcE will have contributed to 9.5 Mtonnes of GHG emission savings.
