Why would concrete producers buy carbon dioxide? It is a waste product of calcining limestone, no? Cement is not supposed to contain any carbonate at the end of the process.

Companies like CarbonCure and Solidia are doing new work on technology that allows concrete producers to inject CO2 into concrete, which makes the concrete stronger. It's really exciting technology, and they've already got plants operating around the country.
