UK consortium has secured funding through the Battery Innovation Programme to develop a localized recycling pathway aimed at retaining critical battery materials within the national economy.
The initiative, known as ReCAM, brings together the UK Battery Industrialisation Centre, Watercycle Technologies, Recyclus Group, and Polaron. Delivered by Innovate UK and supported by the Department for Business and Trade, the project forms part of a broader £452 million national effort to strengthen battery supply chains and support industrial decarbonization.
The core challenge addressed by ReCAM is structural rather than technological. While the UK is building capacity in battery manufacturing and electric mobility, it remains dependent on exporting intermediate recycling outputs, particularly black mass, for further processing abroad. This material contains high concentrations of lithium, nickel, cobalt, and manganese, all of which are essential to battery cathode production. The absence of domestic refining capacity not only limits value capture but also introduces additional emissions and supply chain dependencies.
ReCAM proposes a shift in process architecture. Instead of conventional hydrometallurgical or pyrometallurgical routes that separate black mass into individual metals through multiple stages, the project focuses on a short-loop refining method that converts the material directly into cathode active material. This approach reduces process complexity and, in principle, lowers both energy consumption and operational costs. The system is designed as a modular unit capable of processing approximately 250 kilograms per hour, allowing deployment closer to waste generation points and reducing the need for long-distance transport.
From a systems perspective, the ability to reintroduce cathode materials directly into battery production addresses a key bottleneck in circular supply chains. However, technical feasibility alone does not guarantee market adoption. Recycled materials must meet stringent performance and consistency requirements to be integrated into commercial battery manufacturing. This is where Polaron’s role becomes critical, using artificial intelligence to model the relationship between processing conditions, microstructure, and electrochemical performance. By accelerating validation cycles, the consortium aims to reduce the time required for recycled materials to reach battery-grade standards.
The emphasis on zero-waste operation and lithium recovery reflects growing regulatory and economic pressure to maximize resource efficiency. Lithium, in particular, has become a strategic material, with demand growth closely tied to electric vehicle deployment. Retaining this material within domestic supply chains could improve resilience against price volatility and geopolitical supply risks.
Yet, scaling remains a central challenge. While the modular design supports distributed deployment, achieving meaningful impact will require integration across collection, preprocessing, and manufacturing stages. The UK’s projected 94,000 tonnes of annual black mass by 2040 implies a need for multiple processing units operating at scale, alongside coordinated logistics and market demand for recycled cathode materials.
The project also highlights a broader shift in industrial policy. By linking funding mechanisms to circular economy objectives, the UK is attempting to move beyond linear supply chains toward more integrated resource systems. The involvement of UK Research and Innovation underscores the role of public funding in de-risking early-stage technologies that may not yet be commercially viable without support.
