[60] [61] PET bottles lend themselves well to recycling (see below). In many countries PET bottles are recycled to a substantial degree, [60] for example about 75% in Switzerland. [62] The term rPET is commonly used to describe the recycled material, though it is also referred to as R-PET or post-consumer PET (POSTC-PET). [63] [64]
Polyethylene terephthalate can be depolymerized partially or completely to yield the constituent oligomers or the monomers, MEG and PTA or DMT. The main processes are glycolysis, methanolysis or hydrolysis. [22] [23] After purification, the oligomers or monomers can be used to prepare new recycled polyethylene terephthalate ("r-PET"). The ester ...
