Many countries are laboring on controlling environmental pollution by plastic wastes by reducing plastics and plastic product's production, prohibition of excessive packaging, litter capture and recycling. Despite the fact that plastics are very useful in everyday life, the toxic chemicals used in the production need to be thoroughly monitored so as to ensure environmental and health safety. Polyvinyl Chloride (PVC), a type of heat-resistant polymer, is used for packaging fruit juice, cooking oil, etc. Table 2: Compounds generated during the incineration of polyvinylchloride and their harmful effects.
