Plastic, a widely used material in modern society, poses a significant challenge to the environment when it becomes waste. Landfill and plastic material recovery have been widely used as the way of waste plastic management. There is a problem with landfill, as it can take up to 450 years for plastic to break down (to biodegrade), which cannot really solve the plastic pollution problem.

Pyrolysis is a thermal decomposition process in which large molecules are broken down into small molecules, has emerged as a promising solution to handle plastic waste. But what happens to plastic after pyrolysis?

As we know, plastics are the derivatives of petroleum products and are usually made up of hydro-carbon polymers, in other words, plastic is made from crude oil obtained from the oil well. 5% of extracted oil from under the ground is used for the production of plastic materials, 90% of which form part of 5 types of plastics such as PE(polyethylene), PP(polypropylene), PVC(polyvinyl-chloride), PET(Polyethylene terephtalate ) and PS (polystyrene ). Since plastic has similar components with crude oil, so we can turn plastic back into fuel oil again through pyrolysis. In the process of plastic pyrolysis, long chain hydrocarbon polymer is broken down into smaller chains of hydrocarbon gas and pyrolysis oil.

Recycling plastic into fuel oil will be a better solution to waste plastic management and it is also the one with best economical benefit. Plastic in its raw state is made up of a range of hydro-carbon polymers, after thermal pyrolysis process, the plastic polymers can be broken into smaller carbon chain which is fuel oil. This oil can be used as fuel, such as heavy oil generators, boiler heating, gypsum plants, glass plants, brick plants, steel plants, cement plants, etc. After further refinery, plastic fuel oil can be converted into plastic diesel as a diesel substitute used for industrial heating, heavy machine and generators,etc.

Another important product is carbon black. It has applications in various industries, such as the production of tires, pigments, and inks, construction. Additionally, syngas, a mixture of carbon monoxide and hydrogen, is also generated, while combustible gas can be utilized as an energy source to fuel the pyrolysis process itself, reducing the overall energy consumption.
