How to produce power from plastic waste

@Arun‍ - Have you done any study of your own? Because providing the complete process of the conversion of plastic into power would be beyond the scope of this discussion. 

I'd encourage you to ask specific questions that you face while working on your project / studies, so that our fellow CEans can help you out. 

Many plastics are combustion resistant. If the plastic you are concerned with is combustible, then it can be treated like any other combustible material for power generation.

In the global sense, considering entropy increase one is better off recycling the plastic since quite a bit of power is saved by this .

to know about using plastic waste to useful thing, u can see youtube like one below
