Plastic Pyrolysis

Plastic Pyrolysis

The true challenge in large scale pyrolysis is to ensure safety and manufacture high-quality fuels and petrochemicals. With over a decade of expertise in pyrolysis, APChemi has mastered plastic, tyre & biomass pyrolysis.

What is Plastic Pyrolysis

What is Plastic Pyrolysis?

Pyro = heat. Lysis = break down.


Plastic Pyrolysis is a chemical reaction. This reaction involves the molecular breakdown of larger molecules into smaller molecules in the presence of heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc.


At any given temperature the molecule is in vibrating stage. This is called molecular vibration. The frequency at which molecules vibrates is directly proportional to the temperature of molecules. During pyrolysis, the object’s molecules are subjected to very high temperatures leading to very high molecular vibrations. At these high molecular vibrations, every molecule in the object is stretched and shaken to such an extent that molecules start breaking down into smaller molecules. This is pyrolysis.


The simplest example of pyrolysis is food cooking. When you cook food the temperature of food increases leading to higher molecular vibrations and breakdown of larger complex molecules into smaller and simple molecules. After cooking larger food molecules are pyrolyzed into smaller in simpler molecules which are easy to digest.
