Pyrolysis of plastic waste

What is pyrolysis:

Pyro = heat. Lysis = break down.
Pyrolysis is chemical reaction. This reaction involves molecular breakdown of larger molecules into smaller molecules in presence of heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc.

Pyrolysis of plastic waste to oil machine


Plastic pyrolysis is: the process of converting waste plastic into industrial fuels like Pyrolysis Oil, Carbon Black and Hydrocarbon Gas.

Plastic pyrolysis involves subjecting plastic to high temperature of 400 to 450 degree Celsius, in absence of oxygen. In case of oxygen is present plastic will start burning. During pyrolysis plastic breaks down into smaller molecules of pyrolysis oil, pyrolysis gas and carbon black. Pyrolysis is great a way of recycling waste plastics. This plant can also used for waste tire recycling.
