Metal-free glycolysis of PET/cotton fabrics using ammonium bicarbonate
Researchers at the University of Copenhagen reported a metal-free catalytic glycolysis route for PET and PET/cotton fabrics using ammonium bicarbonate, which decomposes to ammonia, carbon dioxide, and water. The process recovered high-purity BHET suitable for PET repolymerization while enabling cotton recovery, and demonstrated processing at a comparatively large laboratory scale.
