| Abstract: | The status of recycling of waste poly（ ethylene terephthalate） （PET） was reviewed. Main methods for chemical recycling at home and abroad were introduced which included hydrolysis, methanolysis, and thermal cracking etc. Hydrolysis methods included acidic hydrolysis, alkaliline hydrolysis, and neutral hydrolysis. Alcoholysis methods included atmospheric methanolysis, pressure methanolysis, supercritical alcoholysis, ethanolysis, and glysis, etc. The result showed that chemical depolymerization was an effective means for recycling of waste PET. |
