Aqua Metals Secures Additional Patent for AquaRefining Devices and Method
Australia Approves Patent for Smelterless Recycling of Lead Acid Batteries

ALAMEDA, Calif., Aug. 08, 2017 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ:AQMS), (“Aqua Metals” or the “Company”), which is commercializing a non-polluting electrochemical lead recycling technology called AquaRefining™, today announced it has secured another patent: Australia Patent No. AU2014353227, "Devices and Method for Smelterless Recycling of Lead Acid Batteries." The Company believes that AquaRefining is more efficient and cost effective than conventional lead recycling while producing a higher quality product.

The patent was issued by the Australian Patent Office, a division of IP Australia, which is an agency of the Department of Industry, Innovation and Science.  According to the Australian Battery Recycling Initiative (ABRI), over nine million lead acid batteries are purchased each year in Australia.  

"This Australian patent is the second of several international patents we expect to be issued," said Dr. Stephen Clarke, Chairman and CEO of Aqua Metals. "Australia is a significant future opportunity for us given that the government is committed to recycling programs. We are proud of the efforts of our team and believe this latest achievement is yet another notable milestone in the path to commercializing our cutting-edge lead recycling technology."

The Company’s IP Strategy includes planned filings for more than 20 patents, organized into several families covering "matter," "devices" and "processes" in up to 20 different regions.

About Aqua Metals
Aqua Metals, Inc. (NASDAQ: AQMS) is reinventing lead recycling with its patented and patent-pending AquaRefining ™ technology. Unlike smelting, AquaRefining is a room temperature, water-based process that is fundamentally non-polluting. These modular systems allow the Company to vastly reduce environmental impact and scale lead acid recycling production capacity both by building its own AquaRefineries and licensing the AquaRefining technology to partners. This meets growing demand for lead to power new applications including stop/start automobile batteries which complement the vehicle’s main battery, Internet data centers, alternative energy applications including solar, wind, and grid scale storage. Aqua Metals is based in Alameda, California, and has built its first recycling facility in Nevada’s Tahoe Reno Industrial Complex.
