Researchers at Lund University in Sweden have made a significant breakthrough by converting textile waste cotton into sugar. This innovation could potentially reuse cotton waste, which is estimated to be around 100 million tons annually, for the production of spandex, nylon, or ethanol. The team used a method involving sulfuric acid treatment without using microorganisms or enzymes, overcoming the challenges of cotton's crystalline structure and protection chemicals and dyes. This discovery could significantly advance textile recycling.
