Changing World claims an 80% efficiency. The nat gas produced in the
process is used to power the next cycle, since the cost to transport
the gas is not cost effective

Old news. :) I've heard about veggie-plastics for a number of years. A
prof at my university was researching converting garbage into a fuel.
Damn, I should look him up and see what he's doing now. My question is
has anybody found a way to de-polymerize a plastic back into a
pre-plastic state such that the hydrocarbons can be recovered and
converted into a useable fuel. We can recycle plastics by powdering
them and forming the powder into pellets for re-use, but can that
powder be further broken down into basic components?
Hmm...I'm struggling to recall my high school chemistry here, but if I
remember right, polymerization is usually an exothermic reaction.
Presumably even if you could depolymerize the plastic somehow, you'd
have to add all that energy back in to do it. Burning the resulting
fuel might not give you a net energy gain.
