Cyclic Materials

Cyclic Materials is a Kingston, Ontario cleantech company founded in 2021 that is building a circular supply chain for rare earth elements and other critical materials. It recovers neodymium-praseodymium (NdPr), samarium, gadolinium, terbium and dysprosium from end-of-life magnet-containing products — electric-vehicle motors, wind-turbine generators, MRI machines and e-waste — using its proprietary MagCycle magnet-separation and REEPure refining processes, and supplies recycled mixed rare earth oxide (rMREO) and recycled copper back into automotive, data-centre, defence and energy manufacturing. The company operates a REEPure commercial demonstration plant and a MagCycle pilot in Kingston, with a Centre of Excellence under construction there and campuses planned in Arizona and South Carolina. It is a materials producer, not a software vendor: it publishes no API, SDK, developer portal or machine-readable specification, and its only public application surface is an Auth0-gated supplier portal for recyclers, aggregators and core buyers.

Cyclic Materials is profiled on the APIs.io network. Tagged areas include Company, Rare Earth Elements, Critical Minerals, Recycling, and Circular Economy.

Cyclic Materials’ developer surface includes engineering blog and 8 more developer resources.

  detail: Cyclic Materials sells recycled rare earth oxide and copper, not software — its entire public presence is an 85-page
    Webflow marketing site with no /api, /developers or /docs route, and its only application surface, portal.cyclicmaterials.earth,
    is an Auth0-gated supplier portal for scrap sellers whose /api/* routes are Next.js auth plumbing rather than a published
    API.
