    This depends on the plastic, actually. PVC is usually over 50% chlorine,
    and creates huge quantities of dioxin when heated to the 200 - 400 C range.
    Non-chlorinated plastics shouldn't create dioxin, unless there's another
    source of chlorine in the materials being burnt/heated. My guess is that if
    they are measuring dioxins from plastics recycling, it's because of PVC
    contamination of PET or HDPE plastics.
