Plastic to fuel “recycling “ slowly coming on line

Given enough time, money, effort and energy input you can get any hydrocarbon you want from any hydrocarbon source.

This is pretty much what Darren Woods said - and I figure companies currently making plastic from natural gas would know how to recycle at various levels. But when sued and trashed by the media who trust lawyers more - where do you go. People and local agencies are not being responsible - so blame the deep pockets. I’m still PO’d that our county stopped - they even used the inmates who could work off time sorting the bins …
 
Somewhere remote, I'd like to say North Dakota, there's an oil company using methane they can't bottle or pipe to run generators to make crypto. Be cool if they had the logistics to do this plastic stuff.

Pablo,
back in the day (while I was still rpetty ative here), there was a New Zealander who had his own column in his back yard and made his own fuel....

He was pretty active, and we interacted a fair bit...I've used the search function, and can't find it...

The user name was Excalibur, don't depend on my spelling to be 100% accurate on New Zealand English.

I've heard of getting oil out of tires and recycling the steel belts, but how do you get diesel out of plastic? Can you get jet-A as well since it's a lighter petroleum product and is pulled of higher up in the hydrocracking stage?

Tires are easy to recycle. Burn them and magnet up all the steel.

With free tires everywhere and oil usually staying over $70 a barrel how is this not a thing?

Sulphur, and heavy metals

Tires already are, Understand there supposedly are massive numbers of used tires consumed by industry everyday and that’s we’re the so called recycled tires go, asphalt, playground and ground cover, cement makers (oddly) and a variety of other industrial uses.

Why they aren’t used for consumer gasoline…
while “most” plastics have minimal sulphur and will pyrolyse cleanly in an air free environment around 500 degrees with minimal gas output and lighter hydrocarbons ,
tires don’t completely give up the ghost until 1000 with partial decomposition starting around 700ish.
Once you do because tires are much more complex you get lots of nasty chemistry experiments going on during pryolisis which damage the oil/heavy diesel you get out of the process (more chaostic, acidic and sulphur filled) and tires make a lot more very noxious gas output that stinks up the neighborhood than most normal plastics which are nearly single chemical items.

This isn’t to say a big calcium pile and water bubbler couldn’t greatly reduce the most obvious stench but the extra heat energy, chemical additives and complexity makes it more expensive to clean up the hydrocarbons you get out as compared to acid free sulphur free plastic outputs

I love the rubber mulch but now it’s harder to find for me …

The caps and bottles need separating.

This is an interesting subject. Some plastic bottles say to put the cap back on and recycle, but many recycling centers want the caps removed. I once worked with a guy whose "community service" time was spent in a county recycling center. He said he was instructed to send any bottles with caps to the landfill. I usually just play it safe and remove the cap anyway.

Crosslinking is not easy to overcome.

Nothing odd about cement makers using tires. They toss tires into the kiln and the energy from the tires off sets natural gas use and they already have to scrub the exhaust because of chloride vapors and the same scrubbers scrub sulfur dioxide.

Years ago before single stream they wanted the little ring on bottles cut and thrown in the trash, labels removed and no bags allowed .
 
I think the short answer is power. Fuel gives the poorer population the ability to produce at a highly productive rate.

The 'powers' need a reason to say fuel is bad and they use environmentalism to tax and fee people to levels where the powerful keep the means of production in their hands and a steady flow of revenue in their pockets. They don't actually care about the environment.

This is the short answer but I am sure their is much more to it.
