Cyclic Materials™ is building a resilient circular supply chain for rare earth elements and other critical materials. Through our proprietary MagCycle℠ and REEPure℠ processes, we recover rare earths from end-of-life products and transform them into high purity materials used in the production of permanent magnets. These materials are critical to the contemporary economy, including the production of electric vehicles, electronics, AI infrastructure, wind turbines, defense, and advanced manufacturing technologies.

Founded in 2021, Cyclic Materials has rapidly progressed from technology development to commercialization. We currently operate facilities in Ontario and Arizona, with a new expansion underway in South Carolina. Backed by US$75 million in Series C financing led by T. Rowe Price, alongside strategic investors including Microsoft, Amazon, Hitachi Ventures, BMW i Ventures, Jaguar Land Rover’s InMotion fund, Energy Impact Partners, ArcTern Ventures, and Fifth Wall, we are scaling to meet growing global demand for a secure and sustainable rare earth supply.

We have established commercial partnerships with global industry leaders such as Solvay, Vattenfall, Lime, and VACUUMSCHMELZE, enabling the deployment of recycled rare earth materials into real world supply chains. In 2025, Cyclic Materials was named one of the Top 10 Climate Tech Companies to Watch by MIT Technology Review.

We are growing quickly and building the industrial backbone required for a circular rare earth economy. Joining Cyclic Materials means working on complex and exciting challenges at scale, alongside a team committed to executing and delivering measurable impact.



If you are motivated by building critical infrastructure and advancing the circular economy, join us and help accelerate the growth of rare earth recycling.
