The review deals with the hydrolysis of polyvinyl chloride waste in media of alkalis and
organic bases and with the treatment of chlorine-containing waste in critical media (water,
ammonia, methanol, carbon dioxide). The principles and mechanisms of the
hydrodechlorination and hydroconversion of polyvinyl chloride/vacuum gas oil mixtures and
of the gasification of polyvinyl chloride waste and municipal chlorinated plastic waste are
described. Procedures for joint hydrothermal treatment and gasification of polyvinyl chloride …

An increase in the level of production and consumption of polyvinyl chloride leads to the
formation of a large volume of chlorinated waste, mostly as a component of municipal
plastics waste. Incineration of such waste to produce energy results in emission of toxic
gases (SO 2, NO x) and of heavy metals and solid particles with flue gases, and also in
formation of polychlorinated dibenzodioxins and dibenzofurans and of other aggressive
chlorinated organic compounds. Therefore, recycling of waste containing chlorinated …
