Waste plastic homogenization is a restoring process to produce oil by heating and decomposing waste plastics in the reverse direction from manufacturing plastic products using the oil as material in petrochemical industry.

Low temperature pyrolysis is an endothermic system with indirect heating of the wastes by low temperature (350 ℃ ~ 450 ℃) under anaerobic or low oxygen atmosphere and forms unstable radicals with part of the weak adhesion being cut first or a similar structure to the bonding combination of the random torn.

Radical reaction is the main fature. Pro-environmental and excellent clean fuel with prominent value as a resource is produced by less generation of pollutant materials in the transformation process of becoming small molecular weight substances through continuous phenomenon of cutting up of the combination while the energy is being transformed into combining structure of the organics through persistent reactions.
