Nah man, that's just toxic hurtful criticism. Let people brainstorm and just let go of the gavel.

Why did you write that? What do you gain or anyone reading from that comment? Who are you performing for? Where is the audience? Are you bored and I'm your little punching bag? If you know, contribute and tell us if and why I am wrong and I will welcome it, if you don't or it is not worth the effort, just stfu, nobody needs your shit snark.
There was the scientific article and the abstract in the body of the post if you wanted to read it, wtf more do you want?
When emissions are in the trillions of tons, I wonder if it would even be measurable.
emission of what? There aren't trillions of tons of Chlorine in the stratosphere (that's what interferes with O3) being pumped into the atmosphere. Are you thinking of CO2?
I doubt anybody can give a confident answer today about the value of the effect that a kg of Al2O3 can have per ton of atmosphere at ozone layer height, because that would involve not just doing what they did in the paper, but also figuring out what "shape" the Al2O3 particles have to know what their adsorption surface would be, for e.g. zeolites this can be 16m2 per gram. e.g. https://www.sciencenews.org/article/earth-extraterrestrial-space-dust-weight-meteorite but maybe it can be simply extrapolated from analogous metallic meteorite dust samples :/
I was just worried about Kessler syndrome and just felt relaxed that their orbits were low enough to naturally decay and never become a permanent problem. What this research seems to show is that the aluminum oxide dust does not settle in days/weeks, but it is fine enough to stay there for decades :/
heh, yea, the satellites are not just wood for sure, they goofed. But it's less metals, which helps.
I was actually reviewing the O3 depletion process https://en.m.wikipedia.org/wiki/Chlorine_monoxide and Cl only stops reacting with O3 when it ends up as ClO2, but that is rare, because ClO usually is too short-lived to react with another Cl into Cl2O, so it may be possible that a catalyst like Al2O3 could actually clean up Cl interfering with the ozone layer along with the effect of speeding up the nefarious reaction with O3 :D
Magnesium oxides can also serve as a catalyst for lots of reactions, but I'm not sure if it will have the same effect in this specific context, I'd guess it would.
That's why I added the link to the wooden satallites, that also reduces the metal debris somewhat and reduces other effects like radio interference.
The point here is not that aluminum oxide "pollutes" on its own, it is that it "speeds up" the harmful reaction between ozone and any chlorine (like CFC) "pollutants" up there without being consumed, so it keeps acting over 30 years. It makes all the pollutants you mention "more effective" at depleting ozone.
U talkin' to me??
Yea, it's awesome, especially if local government helps set up distributed instances for their citizens https://freediverse.com/w/9ey947PwENGf9BnYTX1jkV
