The Chemical Revolution: A Breakthrough in Textile Recycling

The fashion industry, a realm of creativity and trends, is also plagued by its massive waste. Millions of tons of clothing are discarded each year, with only a small fraction effectively recycled. This not only results in resource waste but also imposes a heavy burden on the environment. About one-third of the microplastics in the ocean come from clothing.

Traditional recycling methods mostly rely on physical means to separate waste into raw materials. However, the diverse composition of textiles has pushed mechanical recycling technology to its limits. Blends of different materials like cotton and polyester make separation and reuse extraordinarily difficult.

To address this challenge, engineers at the University of Delaware have pioneered a groundbreaking technology: microwave-assisted glycolysis. This technology transforms the traditional physical recycling model into chemical decomposition, utilizing heat and catalysts to break down polymer macromolecular chains into smaller units.

This technology exhibits exceptional performance in handling textiles with various composition. For pure polyester fabrics, the method can convert 90% of the polyester to BHET (bis(2-hydroxyethyl) terephthalate) molecules. BHET can be directly recycled for the production of new polyester fabrics. For polyester and cotton blends, the technology can simultaneously decompose polyester and recover cotton.

Research results show that spandex is decomposed into MDA (3,3-dimethylbenzidine) molecules. Notably, nylon and cotton can be extracted intact. The entire chemical decomposition process takes only 15 minutes, showcasing its efficiency and significant economic benefits.

Researchers believe that with further technological optimization, the reaction time will be further shortened. Eventually, 88% of global clothing waste will be recyclable, paving a sustainable path for the fashion industry.
