"We use electricity, and our plant operates at room temperature, and that's why there's zero-emission of gases and effluents from our plant," Dhruvendra Kumar Tyagi, ACE Green's general manager, told Reuters about the firm's replacement of the traditional smelting furnace.
Luminous Power Technologies, owned by France's Schneider Electric and one of India's largest auto battery manufacturers, provides ACE Green with more than 200 tonnes per month of used batteries, which ACE said it turns into 120-130 tonnes of lead and sells back to the firm.
ACE Green has also signed an agreement with Altus Asia Group in Singapore to licence its technology to recycle 5,000 tonnes per year of used lead-acid batteries in the first half of 2022, with the potential to double that capacity in 2023, its Managing Director David Leong said.
The investment for this plant will be $5 million which Leong expects to raise via private equity and private partners. "(The technology) basically solves all the problems of running a traditional lead recycling smelter," said Leong, adding that the company plans to also set up plants in Malaysia, Vietnam and South Korea using this technology.
ACE Green says it has inked licensing and joint-venture deals to recycle 90,000 tonnes per year of used lead-acid batteries with four commercial recyclers in 11 countries, which would produce a total of about 55,800 tonnes per year of lead. It is also planning a 12,000 tonnes per year used lead-acid batteries recycling plant in Australia which would produce 7,440 tonnes per year of lead.
All of that would be equivalent to 1 per cent of the world's recycled lead.
