Well, no, we don’t know that & that’s prob false, it’s just all plastics.
Tire microplastics just get circulated faster bcs they get grinned to a fine powder as part of their initial use (& that float gets flushed away with water). And the stat is stated for water or air.
Which is a problem, I’m just saying that we are producing a much larger scale of this problem that we can currently detect (and detecting microplastics is still in it’s infancy even in lab conditions).
But sooner or later all petroleum based (non-biodegradable) plastics get to be microplastics, we just won’t be around to see it.
Microplastics are the sedimentary boundary that will mark the current extinction event in rocks.
You can weigh new tires and compare them to weights of replaced tires. That would give you the low end estimate environmental tire microplastics deposited based on tire sales. I can’t imagine its not a massive number.
Yes, it is. But compared to all plastics production it’s not a third. Much like clothes aren’t a third either.
But they both release microplastics directly into the air & water, so they enter the circulation quicker. The printer that is gonna end on a landfill will be in the balls of creatures millennia from now.
Supposedly you can recycle them, but normally they will be confined to a a small section of landfill. While “on a landfill” is not a good answer, it’s much better than “in the environment “
You could even argue that leachate is “good” in that it pulls all these contaminants out of the landfill to a concentrated place where they could in theory be removed (and placed in a landfill 🤪)
Landfills at least in the us absolutely are designed to encapsulate waste, to minimize leachate and to control runoff. The whole point is to bury it in a way that it will tend to stay buried.
There is evidence of paper not decomposing because it doesn’t get enough oxygen or water for microbes to do their thing

That printer is not “micro”, it won’t shed detectably, and it will be confined to one part of a landfill
Toner is basically bulk microplastic.

You can’t recycle them (very poorly at best, with extra harmful byproducts).
And landfills are not built like nuclear waste storage facilities.
Everything around us is ‘the environment’.
