  • Emissions from the Cement Industrylumbia.edu

    To produce cement, limestone and other clay-like materials are heated in a kiln at 1400°C and then ground to form a lumpy, solid substance called clinker; clinker is then combined with gypsum to form cement. Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it.
