In the modern world the responses has changes quickly due to the need of person and requirements.

Because Plastics have woven their way into our daily lives and now pose a tremendous threat to the environment For minimizing hazardous effect of this on environment so many steps has been taken by the scientist and research has going on in the support of that i am going to introduce a technique of pyrolysis by the help of which we can convert the plastic and polythene waste in a useful fuel. The waste plastics are subjected to distillation, pyrolysis, thermal cracking and de-polymerization distillation to obtain different value added fuels such as petrol, kerosene, and diesel, lubricating oil etc and use as a normal fossil fuels in the vehicle.
