Overview
Aqua Metals describes itself as building a domestic, closed-loop battery materials platform. According to its website, it is the only company to have demonstrated a commercially proven, sustainable, closed-loop metals recycling process capable of producing some of the world's highest-purity battery materials. Its Innovation Center develops and scales AquaRefining™ technologies designed to produce high-purity battery materials while reducing emissions, minimizing waste, and improving worker safety. The company's water-based, closed-loop approach returns critical metals to the domestic manufacturing supply chain without the furnaces, high temperatures, or toxic byproducts associated with conventional smelting and refining.
