Pyrolysis treatments are interesting regarding the aforementioned plastic refuse makeup. Other successful treatments for feedstock recycling of condensation polymers (PET, ABS, etc.), that allows for the depolymerization and recovery of their constituent monomers (e.g. hydrolysis, alcoholysis, methanolysis, etc.), cannot be applied for polyolefin plastics recycling. In contrast, pyrolysis of polyolefins yields valuable hydrocarbon mixtures of

Thermal and catalytic treatments of plastic wastes present meaningful differences. In terms of mechanism, thermal degradation proceeds according to a radical chain reaction 

The following advantages can be envisaged for catalytic cracking processes compared with simple thermal treatments
