Redwood Materials

Redwood Materials is an American company founded in 2017 by J.B. Straubel, a former Tesla co-founder. Based in Carson City, Nevada, the company focuses on creating a sustainable supply chain for lithium-ion batteries. It specializes in recycling end-of-life batteries and manufacturing scrap to recover critical materials, significantly reducing the need for newly mined resources. The company processes a variety of lithium-ion batteries, including those from electric vehicles and consumer electronics. Redwood recovers over 95% of valuable metals like lithium, nickel, and cobalt, and refines these materials into essential components for new battery manufacturing. By integrating recycling and materials production, Redwood aims to establish a closed-loop system that supports a domestic supply chain and lowers environmental impact. Redwood collaborates with major industry players, including automakers like Ford and Volvo, and battery manufacturers such as Panasonic. The company is expanding its operations with a new facility in South Carolina, aiming to recycle and produce enough battery materials to support millions of electric vehicles by 2030. With a growing workforce and significant investments, Redwood Materials is committed to advancing sustainability in the battery industry.
