Pollution and environmental change are the present problems in our daily lives because of a growing population and industrial growth. Plastic waste causing server damage to human health also. Due to these changes happening in the environment only because of plastic we need to take some measures. The recycling and disposal of plastic are causing environmental pollution. So I think the pyrolysis process is the best way to dispose of plastic waste. Presently we are short of fuels and in the future if fuels completely don’t exist that would be a great tragedy to humans. So we have chosen the alternative resource called pyrolysis. In this research we have mentioned that how the process is taken place that the converting of plastic waste to fuel. This pyro lytic oil can be directly poured into the engines. These fuels can reduce combustion and even reduces the internal loss to the engines which occurred by combustion. The vehicles which emit more smoke can be reduced by using pyro lytic oil. Due to this slight reduction in combustion the pollution in the environment can be decreased.
