Redwood Materials, founded by Tesla cofounder JB Straubel, is leading North America's biggest battery recycling operation in the Nevada desert.CAM (Cathode Active Material), a key component of EV batteries, is the focus of Redwood Materials' recycling efforts.The company recycles over 70% of lithium-ion batteries in North America and generates revenue by selling valuable raw materials.Redwood's goal is to create CAM, the 'new black gold,' through advanced recycling processes instead of mining.The company aims to produce 100 gigawatt hours of CAM per year to support the production of 1.3 million EVs annually.Redwood's circular battery value chain involves collecting used batteries from various sources and recycling them efficiently.The recycling process at Redwood significantly reduces energy consumption, CO2 emissions, and water usage compared to traditional mining.The company faces challenges in producing high-quality CAM that meets battery manufacturers' specifications.Northvolt's bankruptcy highlights the risks in the battery recycling industry, but incentives for US battery production may benefit Redwood.Redwood's innovative approach and focus on sustainability position it as a key player in establishing a secure US source of battery materials.
