**2.1 Incineration and landfilling (pyrolysis processes waste disposal)**

Incineration is a waste treatment process which includes the combustion of waste for recovering energy [8]. Landfills occupy space and are therefore unsustainable. Pyrolysis is a tertiary recycling technology because chemical degradation results in the creation of products with a higher added value than the raw material that undergoes pyrolysis. Pyrolysis is defined as the cracking process in the absence or in poor content of oxygen. By mass, 67 percent of plastic waste may be converted into fuel, gasoline oil, or diesel [8].
