Why is the complete combustion of Polyvinyl Chloride (PVC) a concern?

The concern regarding the complete combustion of Polyvinyl Chloride (PVC) primarily stems from the production of hydrogen chloride (HCl) during the process. When PVC is burned, it undergoes a chemical reaction that results in the release of HCl gas, which can be highly corrosive and poses significant health risks. Inhalation or exposure to HCl can lead to respiratory issues and irritation to the skin and eyes.

The environmental implications of HCl are also considerable, as it can contribute to acid rain when it is emitted into the atmosphere, leading to further ecological damage. Therefore, the generation of hydrogen chloride during the complete combustion of PVC is a critical issue that underscores the need for careful management of PVC waste and consideration of alternative disposal methods that do not harm human health or the environment.
