The DEMOs will support selected territorial clusters in introducing CE practices to their citizens and businesses to (1) help reduce reliance on virgin fossil resources and excessive raw material consumption; (2) increase resilience in terms of self-sufficiency, value chain security, and environmental and natural resource protection; and (3) decrease greenhouse gas (GHG) emissions, thereby contributing to climate-neutral economies.

Climate change, environmental degradation, and biodiversity loss are major global threats that require urgent collaborative action across industries, sectors, cities, regions, communities, and citizens. Half of total GHG emissions and more than 90% of biodiversity loss are attributed to resource extraction and processing. Global consumption of materials, particularly biomass, fossil fuels, metals, and minerals, is expected to double by 2060, and annual waste generation is estimated to increase by 70% by 2050.

TREASoURcE focuses on demonstrating CE solutions in cities and regions across the Nordics (Finland, Sweden, Norway, and Denmark), with plans to replicate them in the Baltics (Estonia, Latvia, Lithuania), Poland, and Germany (within the Baltic Sea Region). The combination of these cities and regions will enable broad reach and significant impact, enhancing the replicability and scalability potential of the CE solutions. A common issue across the regions is the low and decentralised material volumes, which present feasibility challenges and high-risk investments due to difficulties in securing sufficient feedstock in terms of both quality and quantity. Nevertheless, the regions’ strengths lie in their ambitious climate and environmental targets.

The overall objective of TREASoURcE is to initiate systemic change by implementing sustainable circular economy (CE) demonstrations that significantly increase the circulation of products and materials, focusing on high-consumption, waste-generating plastics, batteries, and bio-based side and waste streams in the Nordics and the Baltic Sea Region. This will be achieved in collaboration with companies, communities (including citizens, consumers, regional actors), and experts in the field.

TREASoURcE has three specific objectives:

• Demonstrate the environmental, social, economic, and political impacts of systemic CE solutions (for circular plastics, batteries, and bio-based side and waste streams) in the Nordics.
• Replicate locally tailored systemic CE solutions in the Baltics, Poland, and beyond.
• Promote an inclusive and just transition to CE for all, supported by high-level cooperation with all relevant stakeholders.

TREASoURcE will produce a range of CE-related recipes and guidelines that are easy-to-use and adaptable models for citizens, entrepreneurs, decision-makers, regional actors, and public bodies, facilitating easier and broader replication. These include guidelines for public procurement, public funding, organising sustainable CE events, a Replication Handbook, best available technologies guidance for planning future investments, and support for formulating CE strategies and roadmaps.

The green public procurement recipes will help achieve policy targets, such as climate neutrality goals, with regional policies implemented by TREASoURcE partners.

TREASoURcE will also develop a tool for identifying urban-rural symbiosis opportunities and support further collaboration to deepen the bio-circular aspects of this symbiosis. This includes, for example, optimising material use, replacing fossil resources with renewables, producing local energy, and promoting the local economy through public procurements. These tools significantly contribute to enhancing knowledge and understanding of scientific results, while providing an effective and scalable approach to applying these results, ensuring replication across Europe.

TREASoURcE will contribute to improving regional, national, and EU-level policies by producing concrete, scientifically validated examples co-created with relevant stakeholders, leading to regional and EU-level policy recommendations. Rather than imposing new restrictions, the focus is on safe enabling, expanding, and reinforcing existing best practices through incentives that span rural-urban boundaries and local value chains. This approach improves profitability while enhancing environmental quality.

All tools and demonstrations are developed in partnership, ensuring that the practical knowledge and perspectives of stakeholders are incorporated, thus leveraging their expertise. TREASoURcE will produce CE policies that can help address regional inequalities and unemployment. 

The transition to a circular economy within the EU faces several bottlenecks across the plastics, battery, and bio-based side and waste stream value chains due to challenges in regulatory frameworks. For plastics, a significant bottleneck is the lack of design for recycling, material transparency, and traceability, which complicates the recycling process and impacts the management of recycled product quality. Current regulations struggle to support the feasibility of implementing recycled plastic content requirements due to inconsistent batch quality and safety issues. Furthermore, complex and sometimes conflicting regulations concerning food-contact plastics hinder the effective recycling and utilisation of recycled plastics, adding to the overall difficulty in achieving circularity in this sector.

In the battery value chain, although the EU Battery Regulation sets specific recycling targets, it does not adequately address the reuse and repurposing of EV batteries, which could significantly extend their lifecycle. Moreover, the regulatory environment for second-life batteries and large Battery Energy Storage Systems (BESS) is still underdeveloped, lacking clear guidelines and standards for ecodesign, safe installation, and operation, which slows down the deployment of second-life battery applications in BESS.

For bio-based side and waste streams, bottlenecks are primarily related to the complexity and variability of regulations across different sectors. The sector’s diverse nature means the regulatory framework is highly fragmented, with different rules applying to different materials and end uses. This complexity is further compounded by the rapidly evolving regulatory landscape, which creates uncertainty and hinders investment in innovative bio-based products. Additionally, strict regulations, such as those in the Fertilising Products Regulation and the Animal By-Products Regulation – particularly concerning pollutant limits and nutrient content – impose high compliance costs that discourage the use of bio-based waste streams in fertilisers. This lack of regulatory support for innovative uses of bio-based materials, combined with the high costs associated with meeting stringent safety standards, presents significant barriers to advancing the circular economy in this sector.

The transition toward a circular economy in the EU is being driven by several key regulatory initiatives across the plastics, battery, and bio-based side and waste stream value chains. In the plastics sector, a critical driver is the concept of ecomodulation of Extended Producer Responsibility (EPR) fees. Ecomodulation involves adjusting the fees that producers pay based on the environmental impact of their products, particularly their recyclability and reusability. This incentivises producers to design products with better end-of-life management in mind, thus promoting the use of recyclable materials and reducing the overall environmental impact of plastic products. Another significant driver is the implementation of separate waste collection systems within the Waste Framework Directive across the EU, which has enhanced the efficiency and effectiveness of plastic recycling by ensuring better sorting and processing of plastic waste. Furthermore, the Ecodesign Directives play a pivotal role in promoting the design of plastic products with improved recyclability, durability, and resource efficiency, ensuring that products are easier to recycle and have a longer lifecycle.

In the battery value chain, the EU Battery Regulation is a central driver, setting specific targets for recycling materials from batteries. The regulation also promotes the recovery and reuse of valuable materials in the production of new batteries, thus supporting the circular economy. Additionally, the introduction of the Digital Product Passport through the new Ecodesign for Sustainable Products Regulation is a significant driver in the battery sector. This passport is designed to provide detailed information on the composition and history of each battery, greatly enhancing traceability and transparency throughout the battery’s lifecycle. Furthermore, international and national standards for the safe installation and operation of large Battery Energy Storage Systems (BESS) are beginning to take shape, providing a more comprehensive regulatory framework that supports the deployment of second-life batteries in stationary energy storage.

For bio-based side and waste streams, regulatory frameworks are increasingly supporting the use of these materials across various sectors, including agriculture and energy. New fertiliser regulations facilitate market entry and trade of bio-based products, incentivising the substitution of fossil-based materials with bio-based alternatives. Further policies that encourage the recycling of bio-based materials, such as promoting recycled fertilisers and the use of sewage sludge in agriculture, are potential facilitators for the circular economy.

This stage is still in progress. There is nothing to report at this stage.

The project focuses on improving circularity, efficiently managing and valorising local resources, reducing GHG emissions, supporting natural ecosystems, and, most importantly, increasing climate-neutral and circular practices among citizens, communities, consumers, and businesses.

TREASoURcE territories share an important natural ecosystem, the Baltic Sea, which is impacted by unnecessary logistics, such as the export and shipment of plastic waste due to inadequate waste management infrastructure. In WP7, special attention is given to fostering biodiversity within systemic CE solutions. Proper management of bio-based side and waste streams and the circulation of nutrients is crucial for protecting the Baltic Sea from eutrophication, a significant environmental issue in this marine ecosystem.

TREASoURcE aims to optimise nutrient recirculation and flows, raw material use, and to limit the need for land and energy consumption connected to its approach in both production and waste management as well as in circular business models.

GHG emission reduction is a priority throughout the entire project in SE and KVC-DEMOs. TREASoURcE’s approach addresses streams that are currently not circulated, focusing on producing value-added materials and products for new loops. The emphasis is on urban-rural regions within the TREASoURcE territory, where these streams could be circulated but are often produced in decentralised locations. These streams consist of highly consumed and produced materials and products. For instance, plastic materials are an essential part of daily life, as evidenced by the fact that more plastic waste is generated in households than general mixed waste, with no decrease in global consumption of plastics. Typical consumer goods producers estimate that 95% of their CO2 footprint results from material extraction, processing, and production. GHG emissions will be reduced through project activities and further mitigated through the widespread adoption of project DEMOs and other practices.

Plastics: WP3 will support decoupling from virgin fossil resources by recycling plastics into new feedstock for products such as new polymers and industrial solvents and will promote chemical and mechanical recycling as alternatives to plastic incineration. Production from virgin fossil resources and incineration of plastic waste are significant sources of GHG emissions. TREASoURcE aims to increase the recyclability of targeted non-circulated plastic waste streams from nearly 0 to 90%, mitigating a substantial portion of the associated environmental impact. A plastic waste collection and separation campaign will be organised for citizens, businesses, and those who generate agricultural plastics.

Batteries: WP4 will demonstrate the use of second-life electric vehicle (EV) batteries as energy storage systems, supporting the transition away from fossil-based resources and the production of first-life batteries. TREASoURcE will comprehensively assess 2–3 on-grid and mobile solutions, providing concrete examples for replication. Reusing EV batteries to meet peak electricity demand can achieve a 56% reduction in CO2 emissions compared to natural gas. Additionally, substituting raw material extraction and processing brings substantial environmental benefits. For example, extracting 1 ton of lithium requires mining 250 tons of mineral ore or 750 tons of mineral-rich brine, as well as 1 900 tons of water.

Bio-based side and waste streams: WP5 will promote the use of recycled nutrients and biogas, for example in transport, to replace fossil-based fuels (petrol, gasoline) for both citizens and businesses. WP5 will also encourage the collection of biowaste and bio-based side streams for bio-gasification through value chain building, the development of an e-marketplace, and campaigns. These tools will especially support European farmers in addressing climate change and protecting the environment. Proper collection and processing of bio-based side and waste streams will reduce landfilling and piling of waste, thereby preventing the formation of harmful methane emissions. Waste streams are often not properly separated, and mixtures are incinerated, though municipal waste frequently includes recyclable materials like biowaste and plastics. One of the main challenges is changing consumer behaviour (among both businesses and citizens) to support the collection, proper separation, and use of circular nutrients and biogas products, such as vehicle fuel. Biomethane-based GHG emissions from passenger cars can be 50–80% lower than those from conventional fuels. TREASoURcE will organise campaigns to promote the collection and use of circular products.

The aim of TREASoURcE is to bring different stakeholders closer to the project demonstrations and replications by not only engaging with them but by further involving them in co-development activities. Stakeholder identification, collaboration, and involvement will be delivered through dedicated stakeholder engagement to ensure a fair and sustainable transition to a circular economy (CE).

TREASoURcE CE models will connect environmental policies with social justice to support a just transition. WP2 promotes the implementation of CE practices in everyday life and business, contributing to sustainable human development, environmental sustainability, job creation, and social inclusion. The aim is to build knowledge and capacity among stakeholders, ensuring they understand the benefits of CE and can actively participate in its implementation at various levels.

Project activities will lead to increased circular and climate-neutral practices among citizens, encouraging their participation and educating communities and consumers to seek sustainable alternatives. These actions create positive social impact and improve well-being by fostering active participation and a sense of fulfilment in addressing climate change, improving waste management, adopting circular solutions, and reducing excess consumption. SE-DEMOs help transform individuals’ climate and eco-anxiety (especially among youth) into positivity by showing them how they can influence and be part of sustainable systemic solutions.

The project focuses on supporting European industrial sustainability, leadership, competitiveness, resource independence, and value chain security, with widespread replication supported by policy recommendations and circular business models.

TREASoURcE’s systemic CE solutions establish effective and sustainable CE business models that serve as a foundation for sustainable growth across economies, sectors, and regions. Circulating targeted side and waste streams will enhance value chain security and minimise investment and business risks by ensuring a local supply of raw materials. TREASoURcE will develop CE-smart public procurement schemes to support sustainable businesses, providing a competitive advantage over non-sustainable options. The deployment and implementation of TREASoURcE activities will generate economic benefits both immediately and over the long term, as systemic solutions in key value chains, multidisciplinary demonstrations, and sequenced replication scenarios are put in place. Funding and investment opportunities will be explored to support the implementation of systemic CE-related business plans, with an investment pipeline plan creating a pathway toward circularity. TREASoURcE will also aim to support events in implementing sustainable CE practices.

TREASoURcE’s CE business opportunities and new employment will support Europe’s future wealth and competitiveness, helping to rebound from the effects of COVID-19. Local and regional economies and actors play a significant role in TREASoURcE, as demonstrations will establish new value chains and business opportunities across urban-rural settings.

New jobs will be created across TREASoURcE’s key value chains, including in design and business models, digitalisation, research and development, logistics, waste management and recycling, services, industry and production, reuse and refurbishment, thereby creating new business opportunities. Rural regions, where unemployment may be higher or job diversity is limited, could experience the most significant impact from CE-related job creation, helping to reduce unemployment. The establishment of new value chains in rural-urban settings is expected to create jobs across the value chain, with a particularly high impact on the logistics sector.

The net job effects of TREASoURcE can be demonstrated on economy-wide, sectoral, and regional levels. Most importantly, these effects will be visible across the entire value chain of the targeted key sectors. The project anticipates that new jobs will be created in logistics – a critical component of the targeted value chains – as well as in digitalisation. Establishing facilities and infrastructure to enable material circulation will provide long-term jobs. The shift towards sustainability is expected to create new opportunities for innovation, competitiveness, and job creation. CE practices in the events DEMO will support job development in the event sector. Events are a growing livelihood that provide employment and value to society, communities, and citizens. Events have direct employment effects, as well as indirect effects on supporting businesses (e.g., catering, logistics, accommodation) and additional employment effects in the event region. The event sector has been severely impacted by COVID-19, and new, innovative, and sustainable solutions will provide additional marketing benefits.

The project focuses on supporting European industrial sustainability, leadership and competitiveness, resource independence, and value chain security. Widespread replication will be supported by developed policy recommendations and circular business models.
