Aqua Metals, Inc. is engaged in metals recycling with its AquaRefining technology. It is focused on commercializing sustainable lithium-ion battery recycling that is non-polluting and closes the loop on critical minerals for clean energy technologies. It is focused on building and operating its lithium battery recycling facility, utilizing electricity to recycle instead of intensive chemical processes, fossil fuels, or high-temperature furnaces. Its flagship lithium battery recycling campus - the Sierra ARC (AquaRefining Campus) is a sustainable lithium battery recycling center in North America and commercial-scale deployment of its Li AquaRefining technology. Its process allows for recovery and conversion into high-purity nickel carbonate. It provides equipment and licensing of its lead acid battery recycling technologies in an enabler model. Its process produces high purity metals and alloys that can be returned into the battery manufacturing supply chain or sold into metals markets.
