Alkemio Raises $2 Million to Deploy Modular Rare‑Earth Refinery Cutting Emissions 70 Percent

Rare earth elements power electric‑vehicle motors, wind‑turbine generators, smartphones and defense systems. Yet 90 % of the world’s refining capacity sits in China, forcing miners to ship raw concentrates overseas. The geographic bottleneck leaves most deposits unprocessed and adds carbon‑intensive transport.

Alkemio, a three‑year‑old startup based in Buenos Aires, plans to flip that model. Its technology replaces the traditional 500‑step chemical cascade with a single organic‑based unit that can be installed at a mine site. The modular design targets a 100‑kilogram pilot plant in the United States, scaling from a laboratory prototype. By processing ore on location, the company says it can lower capital expenditure by up to 80 % and eliminate the toxic solvents used in conventional plants.

The $2 million round brings together cleantech investors Dalus Capital, VU Venture Partners, Amplifica Capital, VX Ventures and Epic Angels. Maaike Doyer of Epic Angels, whose fund is making its first Argentine investment, emphasized the urgency: “The world urgently needs the ability to refine rare earths sustainably and reliably, wherever the deposits are.”

Alkemio’s first commercial focus is dysprosium, a heavy rare earth essential for high‑performance electric‑vehicle motors and wind‑turbine generators. The company already holds pilots and letters of intent with miners across Latin America, the United States and Canada. If the technology lives up to its claims, it could enable regions with modest deposits to capture more value locally, reducing dependence on Chinese processing and cutting supply‑chain emissions.

The move adds to a growing wave of startups rethinking critical‑mineral processing. Companies such as Canada’s Cyclic Materials and Italy’s RarEarth are pursuing recycling routes, while REEgen uses engineered microbes for low‑heat extraction. Alkemio’s on‑site, solvent‑free approach offers a complementary path that could accelerate the diversification of rare‑earth supply.

What to watch: successful scale‑up of the U.S. pilot, subsequent funding rounds, and the signing of commercial contracts that could shift rare‑earth refining from centralized hubs to distributed, low‑emission facilities.
