This Discovery Changes Everything—Scientists Find Cobalt Can Be Harvested from Urine

Scientists have found a safe, low-energy way to extract cobalt from used batteries using urine and vinegar. Developed by Linnaeus University and IIT Madras, the method recovers up to 97% of cobalt with fewer emissions and no toxic chemicals. It aligns with U.S. clean tech policy and could transform battery recycling. The process is scalable and under pilot testing—bringing sustainable, circular chemistry into real-world manufacturing.
