A simple yet unique process for converting plastic waste into high-value petroleum fuel

Two scientists working with Indian Oil Corporation (IOC) have developed a simple yet unique process for converting plastic waste, including polyethylene into high-value petroleum fuel, as per Assam Tribune. The duo - Dr Punyabrata Chakraborty and Pradyut Rajkhowa, used a simple technique of de-polymerization which involves breaking of the long chain of polyethylene into smaller parts under certain reaction condition. “Depending upon the number of ethylene molecule in the broken chain, it gets converted into gas, naphtha, kerosene, diesel and soft wax-type material. All the products can be used in different types of machines and to convert into energy,” Rajkhowa told The Assam Tribune. The duo has also moved the authorities concerned for patenting the technique. “Polyethylene is the polymer of ethylene - a gas. Lakhs of ethylene molecules combine together to form a very big chain of molecules to form a polyethylene molecule and become solid. This polymerization reaction takes place under certain reaction condition and in presence of certain catalysts. This polyethylene is used to make carry bags and other household items, and is in very high demand," Rajkhowa who is currently with Barauni Refinery, said.
