Maybe the only thing more worrisome than microplastics everywhere is unstoppable plastics eating organisms everywhere, eating through all plastics everywhere.
Usually these bioengineered yeasts need pretty specific growth conditions in order to eat in this case ethylene glycol, not raw finished plastic. In this case they say "plastic-derived substrates" which means they're pre-processing the waste plastic.
Timescale is the important bit. If organisms degrade plastics in a few hundred years then what plastics are uniquely valuable for will be quite fine indeed.
Perhaps soon you'll be needing to apply stains or sealants to your outdoor plastic items. Maybe even purchase treated plastic products that we worry leach toxic chemicals into their surroundings.

there was a time in history before fungus came along and ate trees so there were just a huge amount of trees around that couldn't decay. (which is why we have coal actually) this could be something akin to that.
Is there any of this ”bacteria converting plastic to fuel/food/neutral stuff“ actually applied anywhere at scale under economically reasonably conditions?
In 2011 researchers identified a fungus named pestalotiopsis microspora. It gained widespread attention because it can digest polyurethane plastic and survive entirely in anaerobic conditions, making it a prime candidate for deployment at the bottom of landfills.
I for one look forward to serving this underground deity.
you, yes you, area "biomass compound", well maybe not quite yet, but soon, as these things go, but most definitly every last putrid smelly horrible thing is a "biomass compound", and when you add in plastic we are talking about most of the stuff found in millions of dumpsters, and most of the stuff actualy in dumps, or sewers.
This then solves the whole issue of what is allowed to go in which can or bin, which is anything you cant get money for or find someone who will hall it away for free.
I am very very sure that volunteers will soon show up wishing to "return to the great nutrient cycle"
but there is nothing to worry about as I am positive that everything will be tested and cynicly proven to be safe for human consumption
Honestly at this point I think the way to go may be to stop using plastics where they're not absolutely required, and to subsequently burn what goes into landfill while producing electricity and reclaiming heat. Better that than this.
I think the legitimate answer was groundwater contamination, but that should be solved for other things we bury. I'm on board for non-biodegradable plastic trash sequestration

Good thing microorganisms are famous for their slow rate of change in dynamic environments…
I'm not sure what this adds. The yeast here is chomping ethylene glycol for carbon, and tons of soil bacteria can already do that.
Reminds me of the Taumoeba escaping the Xenonite enclosures.

Why is that worrisome? Might give the fish a chance whose bellies are filling up with plastic rubbish
for all the reasons in the book/movie/television show 'The Andromeda Strain'.
There’s a fantastically silly but fun book about this the name of which eludes me.

No wikipedia page, but goodreads has it here:

That wasn’t it; I just found it, it’s called Ill Wind by Kevin J Anderson
Not plastic, but 'Cats Cradle' by Kurt Vonnegut has something kind of like that.
Such as in The Andromeda Strain?

If you don't eat your biomass compound goo, you can't have any PlastiYum bacterial sludge

There was a Doomwatch episode on his subject with airliners falling out of the sky bcause all the plastic had been eaten away.
https://en.wikipedia.org/wiki/Doomwatch#Series_One
Didn't that happen in Andromeda Strain? The de-polymerized polymer?
And that episode was stretched out into a novel which I linked to above - https://www.goodreads.com/book/show/99852816-mutant-59

soilent goo, again!

How do you define 'not absolutely required'?
Burn it? With all the talk of carbon capture? Recall that plastic literally consists of a mass of hydrocarbons. Why not bury it?

And here I thought we were going to be fed insects when we hit final-stage capitalism
you are ... plastic insects.
