It's just dry pyrolysis. You can buy a complete plant if you want: (In the US: http://www.polymerenergy.com/; In europe: http://207.57.92.209/wordpress/?page_id=7) Ozmotech's claim to fame is that they spent a couple of years making the resultant oil suitable for on-the-road use in 1st world environments. Like gasification, it sounds like something which is trivially easy to accomplish in rough form, but very tricky to do correctly. If water/steam is added to the pyrolysis mix, there is a variant: http://en.wikipedia.org/wiki/Thermal_depolymerization If you take the numbers from the table "Average TDP Feedstock Outputs<http://en.wikipedia.org/wiki/Thermal_depolymerization#cite_note-7>" TDP would seem to produce 70% oil, 16% gasses, 6% solids, and 8% steam. No idea what is produced from dry pyrolysis. Probably depends on the conditions of pyrolysis. This guy's gizmo seems like it may be a good fit for village level plastic-to-energy, particularly in places that mainly use the oil for generators or are not encumbered by 1st world environmental regulations. The big question is: is it affordable to the people who can make use of it?
