The subject of the research in the article is the system of solid municipal waste management, the choice of a method of sorting and recycling waste to obtain finished products based on the material balance method. For the analysis of production systems, the material balance method is proposed, which allows you to estimate the quantity (mass) waste involved in sorting, processing and receiving finished products and the amount of finished products received at each of the above stages of the waste management system. One of such indicators may be the coefficient of effective waste processing Ƞ (KEPO) in the production of new consumer goods (similar to the coefficient of efficiency), taking into account the economic cycle for the processing of MSW, including the collection, sorting, recycling of waste and the production of new goods in one economic cycle, and the coefficient of waste generation µ (KOO) in the same business cycle, determined by the method of material balance.

The article discusses the process of applying a radio-absorbing coating to the surface of plastic. Vacuum plasma methods make it possible to effectively apply thin films to various surfaces. The main parameters affecting the quality and effectiveness of the properties of the applied coatings are considered.The result of the studied coatings obtained by the vacuum-plasma method showed that a sample coated with aluminum nitride, the transmission coefficient through which has not changed compared to the case of free space, is not shielding, and a sample coated with titanium metal, introducing additional attenuation of the order of 5 dB indicates the presence of absorption.
