A Japanese inventor has found a way to convert plastic grocery bags, bottles and caps into usable petroleum.

Plastic bags are, of course, made from petroleum to begin with, but it is not the same kind of petroleum that is used in fuel. In order to turn home waste into home power the machine heats up the waste plastic and traps the vapors created in a system of pipes and water chambers. Finally, the machine condenses the vapors into crude oil, that can be used for heating on the home level

via New invention can turn your plastic bags into fuel at home.
