Abstract

The present invention relates to methods for integrating CO<2>-mediated mineral carbonation and/or activation in a cement production facility and methods for producing low-carbon-footprint cement, comprising withdrawing at least part of the exhaust gas generated cement production, conditioning it by modifying one or more of temperature, pressure, CO<2> concentration and humidity, subjecting an activatable solid feedstock to a size-reduction operation in a size-reduction apparatus distinct from the raw mill and cement mill, and producing low-carbon-footprint cement by mixing the CO<2>-activated material with the cement wherein mixing is performed feeding the CO<2>-activated material to the cement mill or a distinct mixing apparatus.
