From memory when we distilled in the lab with my friend. We had applied the T° rise curves of classic hydrocarbons which were fairly gentle heating. We did not have a condenser at negative T° (we could just fill it with ice) so we still had a good fraction of gases which were blocked from the atmosphere at the start of the distillation. Then we had two choices: either to separate the different condensates in FCT of the evolution of the condenser T° or to distill everything at once with the condenser T° which rose gradually then do a 2nd distillation or we worked in such a way to release 2 or three products: a "gasoline" with a 0° flashpoint (our gasoline was not great but it still worked (tried in a chainsaw) a "Kero" cup and a third diesel...

We had the same experiences with frying oils, it did it too, some do it with waste oils, it's even easier...

The easiest plastics to distill are Plystyrene, HDPE, and ABS. PVC doesn't work and PET gave us strange reactions in the still... It was emulsified and clogged everything...

What the Dutchman does is interesting, but too DIY / not “refined” enough if I dare say.

Different processes compete, here it is gentle heating.

Why not, but in dedicated stationary installations equipped with non-condensable gas treatment. Why not backed by refineries, even if I doubt that that would interest the oil companies.

Do you think they waited for our advice?

And what interests us... on the Grandpuits site undergoing conversion:
biofuels

The production of biofuel will be made from fat: the supply will consist mainly of used cooking oils. This will be TotalEnergies' third site for this activity, after the Mède and Oudalle platform. Annual production of 170 t of sustainable aviation fuel, 000 t of road fuel and 120 t of naphtha is expected in 000.
Plastic recycling

An activity of chemical recycling of plastic wastes must process 15 t/year from the end of 000. This will be the first site in France to apply this method, which consists of degrade polymers by pyrolysis8.

In September 2023, TotalEnergies reveals its plans for the installation of the mechanical plastic recycling unit in Grandpuits9. Scheduled to be operational in 2026, the factory will produce 30 tonnes of compounds, containing up to 000% recycled plastic materials50.

There is (much) more energy in the CH connections than in the CC connections...the gasifier burned CO...a very poor gas...
It took 100 kg of wood for 100 kg...

In other words, going with a resource that contains H (like plastic) is better.

Otherwise, I'm not sure that gasifiers were tolerated long after the war... It was a crisis solution (ah, aren't we in crisis?)...

15000t/year of plastics.
The Total refinery in Gonfreville (near Le Havre) processes around 12Mt of crude per year.
