Chemical recycling of postconsumer poly(ethylene-terephthalate)bottles
Poly(ethylene-terephthalate), PET, waste bottles was chemically recycled by glycolysis process. The glycolysis reaction was carried out at three temperatures 170, 180 and 190 °C in different time intervals (1, 3, 6 hours) with a weight ratio of ethylene glycol (EG) to PET 1:18 and the zinc acetate as a transesterification catalyst. The glycolysis reaction leads to formation of bis(2- hydroxyethyl)terephthalate (BHET) monomer and various types of PET oligomers. Depolymerization products were further characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). From the results it can be seen that remaining PET products i.e. oligomers are thermally very stable and they are suitable to obtain other polymers.
