I posted this in the science community but I think it could be relevant here too. If its not or I shouldn’t have posted it twice let me know and I’ll remove it! Curious to hear more opinions.

You mean like algae?
Nope! These microbes eat CO2 and poop rocks. Algae like other plants take in CO2 but I believe it gets released back into the environment after the plant dies. Bring stored in a rock is a pretty big difference
But what about when the rock dies?
We make more rocks and bury the dead rocks in the new rocks
The great circle of life.
Rock will never die. 🤘
algae releases oxygen, but then consumes the oxygen again latter when the energy is needed. There is just a surplus that isn’t consumes - everything that makes up the cell isn’t recombined, also oils and such may result as well. Sometimes this surplus rots/burns thus converting back to CO2, but other things can happen (sink to the bottom of the sea where there isn’t spare oxygen to recombine with). Not all recombining is perfect either, sometimes you get coal as a result. The vast majority is recombined, but there is a lot of algae and so just a little bit of difference makes for a massive amount that isn’t. (not near enough to make up for all the fuel humans are burning - but overall the earth seems to have been slightly net negative in CO2 before humans started burning fossil fuels for energy)
Interesting, I had no idea.
Sounds a little too good to be true.
Yeah I hear ya, I’m trying to be optimistic.
even if it is, the polluting wont stop, or emissions from our industries.
Gotta be honest, that’s pretty slick. Making concrete is one of the biggest culprits when it comes to adding CO2 to the atmosphere. Concrete has a very high carbon footprint. If we can find a way to make concrete carbon neutral, or even carbon negative… That would be truly transformative.
Unfortunately using calcium carbonate (CaCO3) from this process to make calcium oxide (CaO) for concrete would release whatever carbon dioxide (CO2) you sequestered in the process.
As you can see, to get CaO from CaCO3 you have to remove a C and two O’s. or properly put, a CO2. Doing this would actually release more CO2 than you sequestered originally because to get that CaO you’d have to heat up the calcium carbonate to a few thousand degrees again, burning more coal or whatever to create the heat.
Paywall.
Weird, I’m able to view it without paying anything.
Thats wild I haven’t had that pop up and I’ve looked at several articles there today. Sorry!
Fuck me in particular, I guess.
Save this site, it can display archived versions of paywalled articles

Or OP could post archived links.
are you using a content blocker? ublock etc
No
that’s your real problem. why, though?
Lazy
Most pay walls can be deleted with archive.md
You should tell OP to post links using that
It got banned on much of lemmy cos apparently it was acting as a Russian ddos tool
Then maybe we shouldn’t use that
Its fine imo but don’t use it if ya don’t want to
