Chemical-free, low-carbon lithium-ion battery recycling through its proprietary Integrated Carbothermal Reduction technology is the specialty of Metastable Materials, a pioneering company. Based in Bengaluru and founded in 2021, it reaches over 90% material recovery with zero waste, extracting metals such as lithium, cobalt, and nickel in commodity-grade forms for uses from steel to new battery cells, while its multi-layered, heat- and fire-resistant packaging keeps hazardous battery waste safe to handle. With a recycling capacity of about 1 GWh, it serves EV manufacturers, battery producers, and recycling partners, cutting water use to 3 liters per kg of waste and advancing a circular economy. Its sustainable approach to critical energy-transition materials has earned recognition including the Karnataka Startup Award 2024.
