Much like Middle Eastern oil production in the 1970s, China today dominates the global refinement of critical metals that serve as the foundation of the United States economy. In the 1970s, America’s oil dependence led to shortages that slowed growth and brought huge spikes in prices. But in recent decades, U.S. fracking technology created a new way to extract oil, transforming the nation from one of the world’s largest oil importers to one of the largest exporters.

Today the U.S. needs another technological breakthrough to secure domestic supplies of metals like lithium, cobalt, copper, and rare earth elements, which are needed for everything from batteries to jet engines and electric motors. Nth Cycle thinks it has a solution.

The company was co-founded by MIT Associate Professor Desirée Plata, CEO Megan O’Connor, and Chief Scientist Chad Vecitis to recover critical metals from industrial waste and ores using a patented, highly efficient technology known as electro-extraction.

“America is an incredibly resource-rich nation — it’s just a matter of extracting and converting those resources for use. That’s the role of refining,” says O’Connor, who worked on electro-extraction as a PhD student with Plata, back when both were at Duke University. “By filling that gap in the supply chain, we can make the United States the largest producer of critical metals in the world.”
