The main data on the production volume of bottles from polyethylene terephthalate (PET) in the world are presented. The main ways of handling used PET bottles as one of the hazardous types of waste for the environment, but promising from the point of view of using their properties, are analyzed. The main methods of handling used PET bottles are considered and a critical analysis of each of them is given. Particular attention is paid to the methods of recycling PET bottles, which made it possible to efficiently use recycled PET raw materials directly for their intended purpose. The features of physical, chemical, biological and combined processing methods are also considered, in particular, combustion, gasification, pyrolysis, plasma decomposition of PET bottles, as well as their decomposition under the influence of microorganisms. The main ways of solving the problem of used PET bottles are proposed. Bibl. 84, Fig. 1.
