Within the framework of the concept of “green chemistry” and cyclic economy (economy of closed technological cycles) the extraction of chemical pollutants Cu2+, S2–, HS––ions from wastewater of various industrial productions was investigated. The research was integrated into a single technological cycle of obtaining new carbon-sulfurcontaining lubricants for special purposes. The loading and antifriction properties of the developed plastic lubricants were investigated. It was established that the antifriction properties (ffr) of the developed plastic lubricants are 1.25–1.45 times higher those of the Konstantin-1 industrial lubricant Konstantin-1 and can be used in the work of friction units of various machines and mechanisms. The tribotechnical results of the developed plastic oils in the “steel-aluminum” friction pair are justified, first of all, by the presence, of technical graphite brand LG-1 plastic oils, its modified forms of “pseudographite” and pyrocarbon, as well as sulfur-containing components CuSx and thiobenzaniline (TBA) in the composition.
