- Ford's successful durability testing of rotors made from 100% recycled rare earth magnets marks a significant advancement in sustainable electric vehicle technology.
- The project highlights the critical role of recycled materials in mitigating supply chain vulnerabilities exacerbated by geopolitical tensions, particularly China's export controls on rare earth elements.
- Future production plans hinge on securing funding for a commercial plant, which could significantly scale up the recycling of rare earth materials in the UK automotive sector.
The successful testing of rotors built with 100% recycled rare earth magnets by Ford is a pivotal moment for the electric vehicle (EV) industry, particularly as it grapples with supply chain vulnerabilities. The recent export controls imposed by China on rare earth materials have underscored the fragility of Western automotive supply chains, making the development of a circular economy for these critical materials not just advantageous but essential. Ford's validation of recycled magnets demonstrates that high-quality, sustainable alternatives can meet rigorous commercial standards, potentially reshaping the landscape of EV manufacturing.
The project, executed by a UK consortium, involved a comprehensive end-to-end supply chain for recycling NdFeB magnets. Ionic Technologies played a crucial role by converting scrap magnets into rare earth oxides, which were then processed into metal and alloy by Less Common Metals. GKN manufactured the finished magnets, which Ford subsequently tested at its Halewood e-motor plant. The results were promising; the recycled magnets performed comparably to those made from mined materials, showcasing the viability of recycled inputs in high-performance applications.
The purity levels achieved in the recycling process were impressive, with neodymium oxide, dysprosium oxide, and terbium oxide produced at high percentages from 100% recycled feedstock. This not only meets but exceeds the minimum batch requirements set by Less Common Metals, indicating a robust recycling process. The ability of the recycled alloy flakes to behave identically to virgin materials during magnet manufacturing further solidifies the case for integrating recycled materials into the production of EV components.
Looking ahead, the project is still in its early stages, with Ionic Technologies pursuing a Final Investment Decision for a commercial plant in Belfast, which aims to produce 400 metric tonnes of rare earth oxides annually. The UK government’s support through the CLIMATES initiative and potential funding for the new plant signals a commitment to bolstering domestic capabilities in rare earth recycling. Additionally, the follow-on project CirculaREEconomy, funded through the Advanced Propulsion Centre UK’s DRIVE35 programme, indicates a growing momentum towards sustainable practices in the automotive sector. This strategic shift not only addresses immediate supply chain concerns but also positions the UK as a leader in the circular economy for rare earth materials in the long term.
