Proprietary Zero Emission and Room Temperature Recycling Processes For Used Lead Acid Batteries (ULABs) and Lead Bearing Smelting Slag

ACE Green Recycling (ACE) has developed a zero emissions electrochemical processes to recycle ULABs and lead bearing smelting slag. Both technologies are modular and operate at room temperature.

For the last 24 months ACE has been operating a commercially viable pilot plant facility in India where it recovers more than 99% of the lead contained in ULABs, using low cost machinery with competitive operating costs  making the overall process more efficient and profitable when compared to the traditional pyro-smelting processes.

The lead slag treatment technology allows ACE to recover more than 95% of the lead and other metallic content contained the slag and reduces the final solid waste by more than 65%.

ACE is currently in the process of obtaining permits in various countries across Southeast Asia and the Middle East. The company expects to start commercial scale production in up to 3 facilities during 2022. ACE is also working closely with the industry under Joint Venture and Licensing models for both ULAB recycling and lead slag treatment technologies. The modular nature of ACE’s technology allows it to deploy flexible operating capacities which can be optimized for relevant geographies.

The speaker will introduce the recycling processes, their benefits compared to smelting and share the latest updates.
