Metastable Materials, a Bengaluru-based startup focused on lithium-ion battery recycling, is looking to ramp up operations and establish a new factory in the coming two years. The company uses a chemical-free technology to extract valuable materials from used batteries, including copper, cobalt, nickel, and lithium. The company claims that this method leads to a high recovery rate of over 90 per cent, positioning itself as a potentially sustainable solution to the growing electronic waste problem.
