This process involves thermal degradation of waste plastic into fuel range hydrocarbon i.e. petrol, diesel and kerosene etc. A thermal cracking process in which waste plastic were melted and cracked in the absence of oxygen and at very high temperature, the resulting gases were cooled by condensation and resulting crude oil was recovered. From this crude oil various products petrol, diesel and kerosene etc. can be obtained by distillation. This process mainly consists of four units i. reacting vessel or reaction chamber ii. condensation unit iii. receiving unit iv. distillation unit. More specifically the degradation of waste plastic except polyvinyl chloride (PVC) and polyethylene terephthalate (PET), respectively, was studied in a semi-batch reactor. Also the effect of temperature variation was studied on the formation of liquid hydrocarbons. The best results were obtained when the temperature was constant at 400°C and after this temperature the somewhat liquid conversion decreases and gas conversion is increased. Furthermore alternate method for disposal of waste plastic is also studied. And the results of this process are found to be better than other alternate methods which are used for the disposal of waste plastic.
