Exxon Mobil's 'Advanced' Technique for Recycling Plastic? Burning It (yahoo.com) 128
An anonymous reader shared this report from the Los Angeles Times:
In recent years — as longstanding efforts to recycle plastics have faltered — Exxon Mobil has touted advanced recycling as a groundbreaking technology that will turn the tide on the plastic crisis. But despite its seemingly eco-friendly name, the attorney general's lawsuit denounced advanced recycling as a "public relations stunt" that largely involves superheating plastics to convert them into fuel.
At Exxon Mobil's only "advanced recycling" facility in Baytown, Texas, only 8% of plastic is remade into new material, while the remaining 92% is processed into fuel that is later burned. [California attorney general Rob] Bonta's lawsuit seeks a court order to prohibit the company from describing the practice as "advanced recycling," arguing the vast majority of plastic is destroyed. Many environmental advocates and policy experts lauded the legal action as a major step toward ending greenwashing by Exxon Mobil — the world's largest producer of single-use plastic polymer... Advanced recycling, which is also called chemical recycling, is an umbrella term that typically involves heating or dissolving plastic waste to create fuel, chemicals and waxes — a fraction of which can be used to remake plastic. The most common techniques yield only 1% to 14% of the plastic waste, according to a 2023 study by the National Renewable Energy Laboratory.
Exxon Mobil has largely used reclaimed plastic for fuel production while ramping up its virgin plastic production, according to Bonta.
The executive director of California Communities Against Toxics complains Exxon Mobil's "advanced" recycling is "the same technology we've had since the Industrial Revolution... a blast furnace." (The article also quotes her as asking "How is that better than coal?") And a UCLA researcher who studied the issue blames misperceptions about plastic recycling on "an industry-backed misinformation campaign." He agrees that the reality is "having to burn more oil to turn that plastic back into oil, which you then burn."

Yes, that's the universal *political* definition of "recycling". But it's not what environemntalists mean by "recycling". The problem with the government definition is that it doesn't actually have any "cycle" in it -- i.e., there is no closed loop from which the matter in products never exit as pollution. Government and industry like the "turn into another product" definition because it allows them to greenwash questionable practices that don't affect the waste stream in a way you can say for sure is a good thing. Something qualifying "recycling" in the government sense says nothing about whether it's good or bad.
The environmentalists'' word for what the government calls "recycling" is "downcycling". I'm not as dismissive as environmentalists are of downcycling, but you have to look at the details of the processes to determine if they're beneficial. You can't just call them "recycling" and say that's a win.
Plastic-to-energy, either by converting it to fuel or simply burning it *as* fuel, is a good example. It's "recycling" in the government sense, and has two potential benefits: eliminating plastic waste and displacing carbon-emitting fossil fuels in energy production. The problem is, it actually generates slightly *more* CO2 than simply burning oil to generate the same amount of energy. And that's not a life-cycle analysis, that's just looking at what comes out of the smokestack. From a climate standpoint we're better of putting plastic in a landfill and burning oil instead, although in practical terms burning plastic *instead* of oil probably wouldn't increase our total emissions significantly. The elimination of plastic waste would unquestionably be a significant benefit.
So plastic-to-energy *could* be somewhat beneficial if we could do it on a large scale, but that's the real question. It's just like existing plastic recycling; that theoretically *could* be beneficial, but as long as virgin plastic is cheaper than recycled it will have no real impact -- not like aluminum steel, or even paper recycling where economics means those things *do* get recycled in meaningful amounts. If petroleum is cheaper than plastic-derived fuels, then plastic-to-fuel will be just another benchtop process with no economic application.
The thing that could certainly make a big difference right away without costing very much is simply to stop using so damned much plastic, especially in places where a functionally equivalent and environmentally superior alternative exists. Fifty years ago if you got take-out chinese food it came in a 100% recyclable, 99.9% biodegradable folding paper box with a steel wire handle. Today it comes in a non-recyclable plastic tray that will last a thousand years in a landfill, because that tray costs a nickel less than the paper box. Would you get upset paying twenty-five cents more on your $30 takeout order for containers you could chuck in the trash?

My personal favourite recycled product is "plastic wood". It's insanely expensive, maybe 4 times the cost of the equivalent wood product, but it's amazing stuff. It's a great way to create a damp proof course/membrane at the bottom of a wooden structure (which also is immune from woodworm) - in the olden days you might use a sacrificial bit of batten which you'd heavily treated, but now there's no need - a bit of plastic wood and you're good for decades. The stuff you buy is properly quality controlled and you can get it with structural ratings if you want too, so it's not "a cheapo shoddy product" by any means.
Ultimately though, this is a chicken and egg problem. Plastic wood (IMHO) has its place in a lot of construction - and could replace a few uses of uPVC and the like (ie. stop making new plastic, and re-use some old stuff). However, the price needs to be much lower and the availability needs to be much better too (right now you can only buy it from a couple of specialists, so shipping is ruinously expensive). When it starts appearing in the average builders merchant, then it'll get used.
Even if it is used in all construction though, it'll probably only still use up maybe 1% of all plastic waste :-(

That's nice to say, but you have to think about what the goal actually is with plastic products.
Take food packaging, for example. Why does a box of cereal come packaged in thick plastic bags inside the cardboard box, or granola bars in aluminized plastic wrappers, or whatnot? The answer is gas permeability. How long your food lasts is directly proportional to how much access oxygen and water vapour have to them. The polymers (sometimes multilayered) that are used have *extremely* low permeability, and thus, allow food to last far longer without quality degradation. This prevents food waste on a massive scale and significantly lower costs and increase available options to consumers. Trying to come up with a biopolymer that matches these properties, maintains them through the point of sale, but then quickly breaks down as soon as you throw it in the landfill without any special treatment, is a really big ask. I'm not going to say "impossible", but it's certainly not something we have today.
Okay, well, what about structural plastics? To this, I'd say, exactly what sort of structural plastics do you want breaking down on you? How is a buried plastic sewage pipe supposed to know the difference between "being in the ground and handling your sewage" and "being in a landfill"? Do you really want all of your plastic pipes, fittings, casings, etc breaking down due to warmth and moisture?
There are certain categories of things, like grocery bags, that one can get away with having a polymer that steadily degrades upon exposure to moisture, etc. But this not most plastic uses.

That's fine for thermoplastics and it's fine so long as you don't care about eg what colour it is. Not all plastics respond to heat by melting (there are quite a wide variety of plastics that undergo polymerisation with heat, so heating them makes them more solid, not less), but the big problem of this kind of direct-use recycling is that it only works if you can first sort the plastic into all the different types and colours. There are only a middle-sized handful of basic plastic types, but there are a dizzying array of small variations for different purposes. If all you care about the material properties is that they can go through a 3D printer and make something that's solid enough when you overengineer it to a degree then that's fine; if you care about cutting every last penny from the cost of producing things and about making things that are "just right" then it's not going to cut it.
You also need to be able to effectively remove all the labels and any residue of foodstuffs etc. That's easy enough to do on a small scale for your household recycling but it's labour intensive; it's quite difficult to do very cheaply and at a large scale.

Plastics are a feedstock that is immensely diverse, varying impure, and whose products have generally chemically degraded since their production. Depolymerizing them (and then using the product liquids and gases in whatever is most economically efficient at the time, whether that's new polymers, vehicle fuels, heating fuels, lubricants, etc etc) is usually going to be the best option.

This is literally what they do. It's thermal decomposition. With traditional burning of plastic waste, you add air and get out a mixture of CO2, H2O, and a lot of pollutants (fly ash, nitrogen compounds, chlorinated compounds, etc). With thermal decomposition, you use little or no oxygen (depending on the process there may be other gases added, such as H2) and get what's predominantly a mix of oil, natural gas or syngas, and coke, with water vacuum-stripped; the goal is specifically to NOT oxidize the carbon, and to NOT get rid of the gas (although there is some oxygen present in the feedstocks themselves). At this point it is basically the same sort of mixtures that you find in fossil feedstocks, and are blended into existing fossil feedstocks. These then go through various refining / separation processes as usual to yield the desired mixtures for end products or feedstocks for new production processes. There is no ash, no nitrogen oxides, and chlorine for example forms HCl which reacts with caustic to form NaCl (salt). Industrial salt is often used in the chlor-alkalai industry, though if sufficiently purified it can also be used as road salt.

I'm really happy to finally see this technology being done at scale. It's taken a long time to get to this point, to get the process efficient enough to be practical.
Cannot we dump plastic in plates subduction zones? (Score:1)
Seems like win-win:
1. we get rid of the plastic
2. we get rid of carbon
Long term it might be a problem as we may need carbon but short term it looks like some kind of a solution...

Sure. If you can a) wait a few millennia and b) dig _really_ deep. Might be more feasible and eco-friendly to shoot it to the moon...
Are oil companies inherently evil or something? (Score:5, Informative)

My guess is that after deciding to lie about climate changes in the 1970, they lost all inhibitions and morality. Understandably, if you do something _this_ fundamentally evil, most other things you can do, including the one discussed in the story here, are small things.

It looks that way, yes. No idea what caused that. Too easy to get rich if you already have no morals?

Why not just get a nuclear plant and depolymerize? (Score:2)
I've wondered about these companies that has so much plastic, what is wrong with setting up a gigawatt nuclear power plant near some coastal area, and using thermal depolymerization to boil all the waste stuff into mineral oil, which can be used for all kinds of things. Yes, this is energy intensive, but doing it this way gets it completely out of the environment, and once set up, nuclear is relatively inexpensive, or if that isn't feasible, solar/wind. At least this gets it out of the environment.

There are probably ways that involve fractional distillation and are no more energy intensive than the processing of petroleum.
Plastic to fuel processes cause cancer (Score:2)
EPA just revoked their permission to manufacture fuel from plastic after a journalist investigation found that the process creates several cancer causing chemicals.

Making something into fuel is not exactly "just burning it."

Yea, I'd draw a distinction between just burning a pile of trash, versu running an incinerator-generator and hydrocracking or other plastic-to-fuel chemistry. I think it's reasonable want to convert the significant amount of unrecycable plastic into energy. Skim all that ocean plastic and throw it into an incinerator, get a little energy to fund the project and start addressing a serious ecological problem. Medical waste is almost entirely plastic, and if you want to crack it into engine oil, then by all me

Synthetic lubricants and hydraulic fluids are hydrocarbons cracked from either crude oil or natural gas. They can be re-refined back into lubricant stock indefinitely, but the sludge that remains is more difficult to get anything useful from. It's got copper, iron, zinc, phosphorous, sulfur, but also all the other chemical modifiers that get added in to the motor oil blends. I have no idea what happens to that sludge. Some of the volatiles vacuumed out of the distilling phase are burned to heat the refinery

At the iron foundry I used to work at, we had to pack the slag and ship it to a dump. But we also would just clean the slash off gear with water and hoses and let it flow out to the pond (this was how things have been for the foundry for about 100 years). Which ended up getting picked up into the superfund project for clean up. Lots of nasty stuff in the left over crap. Everything from lead to strontium. It's nuts.
Plastic "recyclying" has always been a lie (Score:2)
I don't recall the industry telling the truth about it, ever.
And their copying of the recycling symbol numbering scheme was just that - a scheme, or a scam.
Also why are we still using so much black plastic, which all goes straight to landfill?
It's still used extensively for food containers, for restaurant & food court takeaway and for frozen meals.
Again, why??
