Aqua Metals, Inc. — Investor Relations & Filings
Aqua Metals, Inc. specializes in sustainable metals recycling using its patented hydrometallurgical technology, AquaRefining™. This water-based, closed-loop process operates at ambient temperatures to recover high-purity metals from sources like spent batteries. The technology is designed as a clean alternative to traditional high-temperature smelting, eliminating the associated greenhouse gas emissions and hazardous waste. Initially commercialized for recycling lead-acid batteries, the company now primarily applies its technology to the lithium-ion battery market. The core focus is on creating a cost-efficient, circular supply chain for critical minerals such as lithium, cobalt, and nickel, which are essential for electric vehicles and energy storage systems.
