Chemical recycling of polyester textile wastes: shifting towards sustainability
AI summary Read the abstract
This study examines the chemical recycling of polyester textile waste, with a focus on polyethylene terephthalate (PET) fibers, which account for half the global PET market. Researchers explore pathways toward circular sustainability by breaking PET textiles back into reusable chemical building blocks.
Amongst all synthetic polymers used in the clothing industry, polyethylene terephthalate (PET) is the most widely used polyester, its fibres representing half the total PET global market (in comparison bottle PET being less than a third).
