- Аннотация: The need for polyethylene terephthalate recycling is associated with the formation of signifi cant amount of its waste, which should be reprocessed due to the growth of polymer production and consumption of plastic products used in light, chemical, medical industries, in mechanical engineering and instrument making. The main share of polyethylene terephthalate (PET) recycling processes is chemical methods through which various monomers are generated. After purifi cation and modifi cation of these monomers, valuable petrochemical raw materials can be yielded. The review describes the principles and mechanisms of polyethylene terephthalate degradation upon pyrolysis. The infl uence of the heating rate during pyrolysis (fast, slow), type of raw material (pure polymer, polymer waste), additives (modifi ers, stabilizers, fi re retardants), type of reactor in the process (horizontal, vertical, fi xed bed reactor, fl uidized bed reactor, conical tip reactor, rotating dc arc plasma reactor) is considered, as well as the eff ect of processing conditions such as temperature, amount of raw material, pressure, atmosphere, and presence of catalyst on the quantitative and qualitative composition of oxygen-containing compounds formed in the gas fraction, pyrolysis oil, and semi-coke. The infl uence of additives of various polymers in a mixture with polyethylene terephthalate on the formation of products (gas fraction, pyrolysis oil, and semi-coke), additives of plant biomass, and food waste is demonstrated. The eff ect of microwave radiation on the polyethylene terephthalate pyrolysis is considered
