An advantage of plastic incineration is the recovery of energy from the plastic wastes [30]. 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. There are four main categories of recycling which are: primary (which involves the mechanical reprocessing of plastics into a new product with equivalent properties), secondary (which involves the mechanical reprocessing of plastics into a product with lower properties), tertiary (which involves the recovery of the chemical constituents of the plastics) and quaternary (which involves energy recovery from the plastics). This led around 200 countries to completely stop the production of CFCs in the next 7 years and 30 other dangerous chemicals. Regulation of the Ministry of Agriculture on waste incineration, which allow for only licensed plastic waste incineration plants to incinerate plastics, while all other forms of burning plastic waste are banned [37].
