Scientists at TU Wien have developed a non-toxic “deep-eutectic” solvent that separates blended fabrics — like cotton-polyester mixes — within minutes. Cotton stays intact and polyester is recovered almost fully, offering a near-complete recycling method for textiles that were once nearly impossible to reclaim.
