“…As for anything on the earth, PET products also become waste after their useful life is over in addition to the waste produced in its manufacture 2 Due to its nonbiodegradable nature, the major concern about this huge PET waste is the development of a recycling process.…”

Glycolysis of polyethylene terephthalate waste fibers was carried out using excess ethylene glycol in the presence of different simple chemicals, namely, glacial acetic acid, lithium hydroxide, sodium sulfate, and potassium sulfate. Good yields (Ͼ 60%) of the monomer bis(2-hydroxyethylene terephthalate) were obtained using these chemicals as depolymerization catalysts. The purified monomer was characterized by elemental analysis, melting point, IR spectroscopy, and nuclear magnetic resonance. The qualitative and quantitative yields of the monomer obtained using these catalysts are most comparable with the conventionally used heavy metal catalysts such as zinc acetate and lead acetate. The chemicals used, being cheap and comparatively less harmful to the environment, offer further advantages in chemical recycling of polyester waste fibers.
