Chlorinated plastics like PVC / CVPC have incredibly useful physical properties.
However, when they are burned they release a plume of incredibly persistent, carcinogenic, fat soluble chemicals. Dioxins and furans. These are truly evil compounds.
There is no way to burn these cleanly outside of a massively hot, controlled and regulated industrial facility. And even these struggle.
Personally I would not burn plastics unless it was an extreme emergency. There are too many unknowns, and too much that can go wrong. My 2c.
