An estimated 50 million tonnes of electronic waste is generated globally each year
Scientists led by Nanyang Technological University (NTU) have developed a novel method of using fruit peel to turn old batteries into new ones, the university said in a statement on Wednesday (Aug 26).
Through the method, fruit peel waste is used to extract and reuse precious metals from spent lithium-ion batteries in order to create new batteries.
The team has, for example, used orange peel to recover precious metals from battery waste efficiently, and then made functional batteries from these recovered metals, creating minimal waste in the process.
