Bounties attract serious brainpower to the challenge.

CO2 capturing plants are already cleaning the air of it. But the current technology actually produces "waste" with Mineral carbonation putting it down into the ground.

What if instead, they would be able to shape the mineral carbonation into bricks or other things and build houses or even roads with it?

Increased cost of artificial carbonation

Shubhankar Kulkarni

Shubhankar Kulkarni Feb 22, 2021

The idea might not be viable due to the extremely high cost of artificial carbonation. The currently used alternatives (wood, brick, cement) are very cheap and cannot be replaced by a relatively tremendously costly material.

Also, natural carbonation takes a long time and, therefore, makes it reliable for use.

Shubhankar Kulkarni As I understand the author suggests using the "waste" material of the carbon sequestration technology that is already in operation. This is not about aiming to replace the usual building materials coming from natural sources, just to make use of that waste material, if that's feasible.

Povilas S Ahh! I get it. In that case, what is the quantity (a ballpark figure) of the waste that is produced? Darjan Hren

it seems we will have to sequester carbon either way. Plants alone might not be able to cope with the rate at which we release it into the air.

Looks like it could be done https://youtu.be/bmJkNwEpYLU
The video is from 2013. I wonder how far they have taken it by now and why this is not in use everywhere yet

Darko Savic There's quite some companies doing it, but not sure about their cleaning output is. Elon also said he'd give $100mil price for the best carbon capture tech so things are developing slowly in that area.
