Comment on A building material that lives and stores carbon

Where does the CO2 go when it dies?
Look…man…the whole thing about carbon is the carbon cycle, right?
Well we are breaking that cycle by digging up long-sequestered carbon (in the form of long-chain hydrocarbons aka “fossil fuels”) and burning them up in alarming quantities.
At absolute best, this material will be carbon neutral.
We need more phytoplankton…when that consumes CO2 and dies, most of it sinks to the ocean depths forever, instead of coming up to the atmosphere.

I’d heard a fairly novel idea about farming trees and burying them as pulp in old mines, I’m sure it’s just ASKING for some kind of wild underground mine fire but … similar concept

I think that wouldn’t work unless the mine is perfectly sealed.
The pulp would still get eaten and digested microorganisms and carbon released to air.
The reason why we have fossil fuels is because of the carbon that didn’t get released to the atmosphere. It got trapped in a hypoxic water/swamps where bacteria and microorganisms couldn’t decompose it.
