Treasource Project: How the Nordics Are Reshaping the Circular Economy Through Used EV Batteries

Opening: The New Economic Logic Behind an Old Battery

While global attention is focused on the growth of electric vehicle sales, a more disruptive question is emerging in the Nordic region: where should batteries from end-of-life electric vehicles go? The answer concerns not only environmental protection, but also future resource security and industrial competitiveness. The EU-funded Treasource project is turning second-hand EV batteries and recycled materials into "local resources" in the Nordic region. This initiative may seem pragmatic, but it actually points to a brand-new economic growth paradigm.

Background: The Treasource Project and Unlocking Nordic Resources

The Treasource project is part of the EU's Circular Economy and Resource Efficiency Innovation Initiative (CCRIEurope). Its goal is to help the Nordic region unlock the potential value of local resources. The project focuses on two directions: first, giving retired EV batteries a "second life" (such as in energy storage applications); second, reducing dependence on primary resources through recycled materials. This is not an isolated R&D project, but a convergence point where EU industrial policy meets Nordic regional practice.

Underlying Logic: Why "Second-hand Batteries" Rather Than "New Batteries"?

The key to shifting from a linear economy to a circular economy lies in redefining "waste." When an EV battery's capacity decays to around 80%, it no longer meets automotive requirements, yet it still possesses considerable energy storage capacity. The Nordic countries have abundant renewable energy (such as wind power and hydropower), but there is strong demand for grid peak shaving and distributed energy storage. Second-hand batteries, as a low-cost energy storage option, happen to fill this gap.

Behind this phenomenon are three driving forces:

• Resource pressure: Europe is highly dependent on imports of critical raw materials such as lithium, cobalt, and nickel. Geopolitical volatility has prompted the EU to accelerate resource recycling.
• Technological maturity: The costs of battery diagnostics, reconfiguration, and cascade utilization technologies have fallen significantly over the past five years, making a "second life" economically feasible.
• Policy catalyst: The EU Battery Regulation and the Circular Economy Action Plan have set specific targets for member states on recycling rates and the use of recycled materials.

Understanding the Nordic System: Why Did It Emerge in the Nordics First?

The Nordics are not the center of European battery production, yet they have become a testing ground for the circular utilization of second-hand batteries. This is no coincidence; it stems from the structural advantages of the Nordic innovation system.

1. High Social Trust and Cross-Sector Collaboration

The Treasource project involves energy companies, automakers, recycling enterprises, research institutions, and local governments. The Nordic "culture of cooperation"—low power distance, high social trust—enables different stakeholders to quickly reach agreements around common goals. In more fragmented business environments, such cross-value-chain collaborations often fall through due to excessive transaction costs.

2. Robust Digital Governance and Traceability CapabilitiesCircular economy presupposes precise material flow information. The Nordic countries are at the global forefront in digital identity, product passports, and supply chain traceability. The electronic waste management systems of Sweden, Finland, and Denmark provide transparent infrastructure for the flow of batteries from the "vehicle end" to the "energy storage end."

3. First-Mover Advantages in the Energy Transition

The share of renewable energy in the Nordic power grid is among the highest in the world. As the share of wind and solar power rises, the grid's demand for flexibility increases sharply. The commercial pilots of second-life battery energy storage systems in Norway, Sweden, and Finland directly serve the Nordic energy transition goals. This ecosystem, where problems and solutions emerge simultaneously, makes Nordic companies more willing to accept early-stage technological risks.

4. Education System and Public Awareness

Nordic engineering and environmental education emphasize systematic thinking. Both consumers and engineers tend to embrace the values of "repair, reuse, upgrade" rather than "disposable." This cultural foundation makes it easier for circular economy innovations to gain social license and market support.

Global Significance: The Circular Economy from "Slogan" to "Infrastructure"

The Treasource project reveals an important trend: the circular economy is no longer a marginalized environmental proposition but is becoming a core element of national competitiveness. By transforming second-hand batteries into local resources, the Nordic countries have reduced their dependence on external supply chains while creating new employment and industrial opportunities.

This model offers three major lessons for the world:

• National strategy for resource security: For any country dependent on imported critical raw materials, treating urban mining as a strategic reserve is an inevitable choice. The Nordic countries have proven the feasibility of this path.
• Synergy between policy and market: EU regulations provide clear targets, while Nordic practice demonstrates how regulatory requirements can be transformed into business opportunities through an innovation ecosystem.
• Value shift from products to services: Batteries are no longer single-use products but assets that can circulate multiple times. This mindset requires synchronous upgrades in financial instruments, insurance mechanisms, and digital platforms.

Long-Term Trend Outlook: The Next 5–15 Years

In the next five years, the cascade use of second-hand batteries will move from pilots to scale. The Nordic countries are likely to take the lead in establishing a "Battery Passport+" system, where the complete lifecycle data of each battery becomes the basis for transactions and regulation. By 2030, as European battery recycling capacity comes online, recycled materials (such as regenerated lithium and regenerated cobalt) will enter mainstream supply chains, and the cost of second-life battery energy storage is expected to be lower than that of pumped hydro storage.

By 2040, the circular economy will not be limited to the battery sector. Nordic practices may extend to more critical components such as wind turbine blades, solar panels, and rare earth magnets. By then, resource recycling will become the basic operating system of economic activity, just as the Internet is today.

Conclusion: A Social Contract Under Experiment The Treasource project appears to be a technical project, but its deeper significance lies in redefining the boundaries of "resources." Nordic people regard waste as "misplaced resources," which reflects a sober awareness of ecological limits and confidence in technological rationality. This awareness is turning the Nordics into a laboratory for the future circular society. For the world, what deserves attention is not just the circulation of second-hand batteries, but how the Nordics, through institutional design, social consensus, and market innovation, are turning circularity from metaphor into reality.
