How is PVC recycled?
Feedstock recycling is more suitable for unsorted plastic mixtures and waste streams containing composite materials. These processes involve (usually) thermal treatment of the PVC waste stream with recovery of hydrogen chloride that can then be returned to the PVC production process or used in other processes.
How is PVC disposed?
Disposal in Incineration
When burned, PVC releases the gas form of highly corrosive hydrochloric acid. Incineration regulations state that this and other resultant toxins must be contained and neutralized, but troubling amounts have been found to leak into the atmosphere.
