RaRE – Rare-Earth Recycling for E-Machines

In plain English

AI plain-English summary

A pilot plant in Birmingham will turn waste magnets from old electronics into new magnets for electric car motors, then build a complete motor to Bentley’s specifications. This matters because rare-earth magnets—used in everything from power steering to air conditioning compressors—rely on materials mined almost entirely in China. Recycling them avoids the environmental damage of mining and the geopolitical risk of a concentrated supply chain. Currently, almost no rare-earth magnets are recovered from end-of-life products in the UK. If the RaRE project succeeds, it will demonstrate the first recycled rare-earth motor ever built. The team will prove that recycled magnets can match virgin material in magnetic strength, mechanical durability, and corrosion resistance. Unipart will then design a flexible assembly line capable of producing 100,000 such motors per year. For electric vehicles, this could mean motors designed from the start for recycling, reducing the complexity of electrical systems and cutting the carbon footprint of each car. For the wider economy, it offers a domestic source of a critical material that currently has no UK supply chain at all.

RaRE will establish an end to end supply chain for recycled rare-earth ancillary motors. Building on work completed at the University of Birmingham to devise a method to extract magnets from waste electronics the process will be scaled and the material re-processed back into new magnetic materials at pilot scale by Hypromag to demonstrate the quality of material which can be produced in terms of its magnetic behaviour, mechanical performance and corrosion resistance which are key to the end user application. The recycled magnets will be built into an ancillary electric motor designed by Advanced Electric Machines Research to a Bentley Motors specification and focused on reducing the overall complexity of electrical systems in electric vehicles and designed with recycling in mind. This will be the first time that such a recycled motor will have been demonstrated. Unipart will take this motor design and use it as the core focus for the design of a flexible volume motor assembly line suitable for production volumes of 100,000 units p.a.
