Redwood Materials, the electric vehicle (EV) battery recycling corporation founded by Tesla co-founder JB Straubel, has been making serious moves as it bolsters its foothold in the zero-emission car business. It recently struck a deal with General Motors (GM) to recycle production scrap and component material for GM's Ultium cells. The announcement came on May 23, and Redwood will collect materials from GM's Warren, Ohio, and Spring Hill, Tennessee, facilities.
