Currently, the problem of recycling polymer waste materials is becoming relevant not only due to environmental protection but also due to the shortage of polymer raw materials. From 1 kg of waste (polyethylene terephthalate, polypropylene, low-density polyethylene, high-density polyethylene), 0.8 kg of secondary raw materials are obtained. The popularity of plastic is explained by its lightness, economy, ease of use. Also, the production of plastic requires 21% less energy than the production of glass.
