Study: Nth Cycle’s Critical Mineral Refining Technology Verifies 92% Reduction in Refining Emissions

Nth Cycle, the innovative metal refining technology company, announced independent verification of its low-emissions refining technology, called electro-extraction. According to the independent study, the Boston-area company offers refining capabilities that are 92% lower emissions than traditional mining and refining processes and 44% lower emissions than more modern critical minerals recycling technologies.

“With the passing of the Inflation Reduction Act, there’s now a growing gap between supply and the extraordinary demand for critical minerals to build lithium ion batteries,” said Megan O’Connor, co-founder and CEO of Nth Cycle. “We cannot rely on emissions-intensive refining processes from overseas vendors to meet our demands. This independent validation proves our ability to create a sustainable path to a sustainable planet right here at home.”

Nth Cycle’s first product is a mixed hydroxide precipitate (“MHP”), which contains nickel and cobalt. Production of MHP through laterite ore refining is growing in popularity as a precursor chemical for battery cathode manufacturers. However, 81% of today’s MHP supply is refined in Indonesia, by Chinese companies, through a carbon-intensive hydrometallurgy refining process called HPAL (high pressure acid leaching). This HPAL-based supply of MHP is harmful to the environment and as a foreign supply, is not a compliant supply of critical minerals for domestic battery manufacturing under the recently passed Inflation Reduction Act.

With this independent verification, Nth Cycle customers can have confidence in a domestic supply of MHP that meets compliance standards for EV tax credits under the Inflation Reduction Act while dramatically reducing the carbon footprint of domestic refining.

Nth Cycle’s unique, modular electro-extraction technology supports refiners, miners and battery recyclers as an alternative or enhancement to older, emissions-intensive hydrometallurgical and pyrometallurgical processes. Nth Cycle’s technology transforms the outputs of metal scrap, electronics recycling, untapped mining resources, and waste from existing mines into high-purity critical minerals ready to be used in new production.

Nth Cycle is hiring and has open positions in engineering, business, and the sciences.
