Initial Testing of Aqua Metals’ Li AquaRefining Shows Potential for More Than 95% Reduction in Carbon Footprint Over Other Lithium-ion Battery Recycling Methods

Li AquaRefining pilot installation on track to recycle high value minerals from black mass in Q4

RENO, Nev., Oct. 25, 2022 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ: AQMS) ("Aqua Metals" or the "Company"), a leading innovator in metals recycling with its AquaRefining™ technology, today shared three significant updates:

  • The comparative environmental figures (fig. 1) indicate the superiority of Li AquaRefining at current scale vs. current Lithium-ion Battery recycling technologies regarding CO2 emissions and sodium sulfate waste streams
  • The on-schedule production of lead (Pb) at AQMS partner ACME Metal Enterprise in Taiwan using Pb AquaRefining
  • The near-term launch of the company’s U.S.-based Li AquaRefining pilot plant currently on schedule to meet the company’s goal of producing high purity metals in Q4 2022

This progress is a testament to Aqua Metals’ standing as a breakaway recycling innovator in the rapidly growing, high-demand critical battery minerals industry. In fact, AQMS is the first LiB recycling company on track to recover all critical minerals from spent lithium-ion batteries and return them into the battery supply chain within the U.S. This positions AQMS to support EV and battery manufacturers’ initiatives to meet the tax credit requirements of the electric vehicle (EV) production of the Inflation Reduction Act of 2022, which requires 40% of all battery materials, by value, to be produced in the U.S. by 2023, increasing to 100% by 2029.

Quantifying Success: AquaRefining’s Environmental Superiority

Aqua Metals recently conducted and released an environmental comparison using competitor data derived from EverBatt, a closed-loop battery recycling cost and environmental impacts model from Argonne National Laboratory. The initial results indicate that AquaRefining has a cleaner approach to LiB recycling, producing far less CO2 waste streams than the two evaluated primary processes currently on the market: pyro-based (smelting) and other hydro recycling methods in development.

“Aqua Metals recycles the minimal amount of chemicals we use in our closed loop process, resulting in relatively little waste stream compared to other commercial processes,” said David Regan, VP of Commercial at Aqua Metals. “Aqua Metals’ unique recycling process puts us on a path to achieving net zero emissions, and positions us as the best recycling partner for companies that need to recycle lithium-ion batteries while lowering their carbon footprint.”        

Taiwan Pb AquaRefining Pilot Program

In September 2022, Aqua Metals delivered on its agreement with ACME Metal Enterprise to deploy AquaRefining technology at its facility in Keelung, Taiwan. A successful commissioning of AquaRefining equipment and lead production followed in October. “This installation meets Aqua Metals’ visionary goal of creating ultra-pure lead through the only proven green method for recycling it in the APAC region, the largest and fastest growing lead market in the world,” said Ben Taecker, Chief Engineering and Operations Officer of Aqua Metals.

U.S.-based Li AquaRefining Pilot Plant Progress

Aqua Metals’ fully integrated pilot system, located at the company’s Innovation Center in the Tahoe-Reno Industrial Center in Nevada, is on schedule to meet the company’s goal of producing high value minerals in Q4 2022 and will host potential strategic partner visits in Q4 and into Q1 2023. This puts AQMS on pace to reach its goal of becoming the first company in North America to recycle battery minerals from black mass and sell them in the U.S. and positions the company as the first LiB recycler in North America to align with the U.S. government’s goal of retaining strategic battery minerals within the U.S.

“Aqua Metals is at an inflection point. In the coming weeks, we intend to demonstrate something truly innovative: an economically viable and sustainable battery recycling operation,” said Steve Cotton, President and CEO of Aqua Metals.

The Right Recycling Technology at the Right Time

It is predicted by the International Energy Agency that there will be approximately 140 million EVs globally by 2030, creating a massive demand for LiBs and the critical minerals used to make them. In addition to higher costs, geopolitical risks, human rights abuses, and environmental issues associated with mining some of the metals used in lithium-ion batteries, mining alone cannot meet the demand of this exponentially growing market.

Recycling the more than 15 million tons of LiBs that are expected to retire between now and 2030 needs to be done sustainably to meet the carbon reduction objectives that the U.S., EU governments and major corporations have set for themselves. Recycling also enables the retention of these strategic minerals within the U.S., helping to defend against the at-risk supply chain for lithium-ion battery manufacturing.

In conclusion, noted David Regan: “With lithium-ion battery technology serving as the foundation of the ongoing clean energy and EV transition, how the minerals used to make batteries are sourced and recycled is vital to meeting global emissions targets. There is already a large and rapidly growing supply of spent LiBs, making it imperative to build a cost-effective, scalable recycling infrastructure that is environmentally sustainable from inception.”
