The SEC has processed a new filing that suggests Tesla may be at work on yet another new initiative. Specifically, the filing shows a $2 million investment in a months-old, Redwood City, Ca.-based company called Redwood Materials that describes itself at its site as focused on “advanced technology and process development for materials recycling, remanufacturing, and reuse.” The filing lists Tesla’s cofounder and CTO, JB Straubel, and Tesla’s head of special projects, Andrew Stevenson, as executive officers.
