Chemical recycling of waste poly(ethylene terephthalate) (PET) is an effective way to save energy and protect the environment. In this work, calcined sodium silicate was adopted as a novel solid base catalyst for methanolysis of PET for the first time. The effects of various parameters on the conversion of PET and the yield of dimethyl terephthalate (DMT) in the methanolysis process of PET were investigated.
