I'm probably missing something obvious.
> The world needs CaO for cement. We have a carbon neutral process for making it
vs
> We make synthetic limestone using atmospheric CO2, such that when it is used to make cement, the process is carbon neutral.
Do you make CaO or CaCO3?
- marcuslima 5y agoWe make CaCO3, I mention CaO here because that's what cement producers ultimately need. They heat up limestone (CaCO3) to make CaO
- coryrc 5y agoIs there a reason not to make quicklime instead of limestone?
