Turning PLASTIC back into oil

The final result is one of the highest energy costs (or perhaps the highest, I should check it out) in the EU.

Not quite Daiquiri, the champion is Holland, but Italy is the runner up.

An extremely interesting thread, would the principle also work for thermo-hardening plastics like polyester? Worth an experiment.

This is the company site (english page): http://www.blest.co.jp/seihin-english.html
It reads "Recyclable plastics are polypropylene (PP), polyethylene (PE) and polystyrene (PS)"

That's what I already feared: these are various hydrocarbons.
Polyester has a lot of oxygen in the molecules, heating it in a closed vessel may have surprising results.

This japanese machine, being a way of getting an apparently free fuel, could be seen as a revenue loss or tax evasion by our myopic governments (which means - a majority of them). Anyways, we'll see. The first news about this invention dates back to the summer 2010, I bet that the very next day the financial sharks were already working on getting the plans ready and exclusive rights for it's exploitation.

Yeah great PR.........

Nothing new, nothing was invented, not even developed. All old hats.

He just uses a pressurized uncontrolled depolymerisation. And the result is unpredictable in its properties.

The "pressureless catalytic depolymerisation" which I mentioned here several times now, is much more efficient, less costly and produces (due to the right catalyst) just plain Diesel fuel of the highest quality.

But as always it has other disadvantages. The raw material needs to be shred, for example.

Newbie needs cost estimate: woodgas people transporter
Mining the Great Pacific Garbage Patch
Diesel Boat Heaters
Getting Out Of The Box With Hot Air
Designing a plastic bottle island/floating platform

and so on....

These systems can be made to any size of course, but it is not very sensible to have a apparatus costing 12k $$$ and processing 0,8 ltr of unrefined (useless) fuel in two hours, while consuming the enrgy content of 1 ltr Diesel.

Having a plant of 14 mio $$$, and producing many tons a day, while consuming only 5% of the processed Diesel, that makes sense. (and profit)

And that is exactly what the Axiom Energy company* and the inventor Koch in Germany sell at present (and since ten years)

Interesting stuff about the chemistry involved and the problem of working this system with insufficient heat. There's a lot of really ugly compounds that can be released if done incorrectly I gotta wonder if that's not what happened to the other folks who developed similar systems.

I like it, but I think you would have to flash the plastic in a preheated compartment rather than let them be subjected to less than optimal temps for any length of time.

I wonder what happened to the rest of the people who had been doing this all along? Out of business? Why is this Japanese guy claiming to be the first. He's only the first in Japan.

And what happened with Axiom Energy?
Did they succeed in collecting the funds and actually built the installation? All web pages I found referred to the plans in 2005, no plant being built, test results, commercial figures etc.
