- Аннотация: In the modern world, the environmental problem is one of the most important. The amount of plastic waste increases sharply every year. The recycling of such waste is complicated by a large number of types of plastic and the difference in their structure. Polyethylene terephthalate (PET) is widely used in everyday life, as well as polyethylene and polypropylene, but in contrast to them, PET contains esters groups. Thus, this plastic can be recycled with various polar reagents, such as water, alcohols, glycols, and so on. This paper describes a method for the depolymerization of PET using the main byproduct of biodiesel production-crude glycerol. waste PET and crude glycerol, a raw material containing potassium salts of fatty acids, which were formed during alkaline catalysis of the biodiesel production reaction, were used as raw materials. Complete PET conversion can be achieved in 90 minutes at 190-195° C and at atmospheric pressure. As a result of the recycling of PET and biodiesel wastes, valuable products such as the potassium salt of terephthalic acid, its esters with glycerol and glycol as well as fatty acids glycol esters can be isolated.
