Conventional primary metal production relies on pyrometallurgical smelting, which consumes large amounts of fossil fuel, generates high CO₂ emissions, and cannot efficiently process heterogeneous feedstocks such as end‑of‑life batteries or mixed industrial scrap. The inability to recycle these complex streams limits resource recovery and increases waste disposal costs. Boston Metal offers a high‑temperature electrochemical processing platform that replaces carbon‑intensive smelting with electrically driven reduction reactions.
