Fuel from waste plastics

[BFG Central]

After the SHTF oil/fuel will be in short supply.
Almost every product you touch is made from some sort of plastic.
Carpets, clothes, tv housings, furnature etc.
Plastic is made from oil and this process can be reversed using a method called Pyrolysis.
Basically its heating the waste plastic in an oxygen free environment. (metal container)
Whats given off is a gas and oil vapor that is condensed in water and the once running the gas that the Pyrolysis produces is used to keep the system running.
They are doing the same thing with old tyres.
A simple setup could be made at home if your hands on.
