Abstract. Cement manufacturing is an energy and carbonintensive industry. The cement industry contributes approximately 5% of the global manmade carbon dioxide (CO2) emissions and is thus becoming the second largest CO 2 contributor in industry after power plants. A wide range of options are available to considerably reduce CO 2 emissions.
