August 29, 2025: Ace Green Recycling said on August 20 it would deploy a new grid metallics processing system to support antimony recovery and boost sustainability in lead battery recycling.

The firm claimed its proprietary GMPS system would allow recyclers to recover clean alloy metal directly from their battery-breaking systems, “bypassing the need for a smelting furnace”.

GMPS, which Ace said operates at room temperature, produces high-quality lead alloys more efficiently and helps recyclers debottleneck their operations, enabling them to process more lead battery paste without increasing existing smelting capacity.

The system is being deployed in key markets where the firm’s lead recycling technology is in operation, including Armenia (Mel Metals), Taiwan (ACME Metal Enterprises), India (Raj Metal Industries) and Thailand (IPP Lead and Metals).

Ace did not give a detailed technical breakdown of GMPS’s capabilities, but said it expects that its solution can enable lead battery recyclers to increase their throughput by up to 25%, by freeing up smelting capacity.

CTO and co-founder Vipin Tyagi said the system makes smelting capacity more efficient by processing grid metallics separately. “It also prevents the loss of valuable alloying elements that are typically burned off during high-temperature smelting.”

Tyagi claimed Ace is seeing significant commercial interest in GMPS from emerging markets and the firm planned to explore new markets for the system soon.

ACE claims its existing GreenLead technology replaces the smelting furnace, operates at room temperature, runs on electricity and has zero Scope 1 greenhouse gas emissions (direct GHG emissions such as those made while running boilers and vehicles) and reduces solid waste by more than 85%.

Batteries International reported last June that the firm had agreed a master offtake deal for lead battery material in Australia with Perth-based Enecell.
