New PET chemical recycling process was developed and demonstrated in the 15kg/hr pilot testing, which can recover the terephthalic acid and ethylene glycol from post-consumer PET bottles. The developed process consists of aikaline depolymerization of PET to monomers and crystalization and purification of TPA. Through the pilot testing, it was confirmed that the recycled TPA can be used for food-container according to the FDA analysis evaluation and economical feasibility study of the commercial plant showed the competitiveness to conventional material recycling plants.
