The team demonstrated their concept using orange peel, which recovered precious metals from battery waste efficiently. They then made functional batteries from these recovered metals, creating minimal non-toxic waste in the process. Credit: NTU Singapore ============================================================================ Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed a novel method of using fruit peel waste to extract and reuse precious metals from spent lithium-ion batteries in order to create new batteries. The team demonstrated their concept using orange peel, which recovered precious metals from battery waste efficiently.
