Cement Manufacturing: Ways to Reduce CO2 Emissions

Feb 11, 2020  Cement is the largest man-made material in the world. With the global population set to hit 8 billion soon, the demand for cement is about to skyrocket to unprecedented levels. However, cement manufacturing is linked inexorably to the ongoing phenomenon of climate change. Greenhouse gases like CO2 trap the sun’s heat and cause the average temperature to increase in the world.

Emissions from the Cement Industry

May 09, 2012  Indirect emissions from burning fossil fuels to heat the kiln can be reduced by switching to alternative fuels, including natural gas, biomass and waste-derived fuels such as tires, sewage sludge and municipal solid wastes.
