Recycled polymer materials

Nowadays the problem of recycling of secondary polymeric materials is of topical importance, first of all from the point of view of environmental protection, but also from the fact that in conditions of polymeric raw materials deficit plastic wastes become a powerful raw material and energy resource. Therefore, the utilisation of polymer waste is an urgent task. At present there are several ways of utilisation of waste polymeric materials, in particular burial in soil, incineration, thermal methods, creation of biodegradable polymers. But all these methods have significant disadvantages. In the monograph on the example of polymer industry wastes, in particular polyethylene and its wastes by chemical modification (chlorination, amination, etc.) new products are obtained, polymer-polymer systems are created, which were reapplied in the polymer industry, thus offering waste-free, low-tonnage technologies.
