Pretty cool machine this guy invented. Plastic is made from oil so why not turn it back into oil.
I was looking for the term ,you mention, it looks promisingthat system probably needs as much fuel/energy to run as it gets out in usable oil.
the better systems use a catalyst to crack the hydrocarbons do a search for
"catalytic depolymerization" some fun with an 80% net energy return sest of all you can rug wood, plastic tires dead animals anything with hydrocarbons
