“…Its growing production and extending application field (housebuilding, health care, transport, agriculture, information technologies, and textile manufacture) [ 1 , 2 , 3 ] make the utilization of PVC wastes a pressing problem [ 3 , 4 , 5 , 6 ]. Chloropolymer solid wastes cannot be treated by thermal-oxidative methods or pyrolysis like other polymers [ 3 , 5 , 7 , 8 , 9 , 10 ], because in the temperature range of 500–1200 °C high-toxic substances are formed; in particular, polyaromatic compounds, benzo(a)pyrenes, and dioxins (2,3,7,8-tetrachlorodibenzo-p-dioxin and a large group of structurally and toxicologically related compounds) [ 1 , 5 , 7 , 11 ]. Given this connection, it is necessary to develop methods for the removal of covalently bound chlorine from PVC at relatively low temperatures (below 500 °C) [ 12 ].…”
