Manufacturing process | Home : Lafarge - Cement

Why does the manufacture of cement produce CO2? Cement manufacturing is the source of 5% of global CO2 emissions. The cement industry is a natural producer of CO2: 60% of emissions are due to the transformation of raw materials at high temperatures (the "decarbonation" of limestone), 40% result from the combustion required to heat the cement kilns to 1500°C. Kiln reliability . Ensuring a good ...
