New approach suggests path to emissionsfree cement MIT News
Sep 16, 2019 · A variation of this process can be used to convert calcium carbonate (CaCO 3) into calcium hydroxide (Ca(OH) 2), which can then be used to make Portland cement without producing any greenhouse gas emissions. Cement production currently causes 8 percent of global carbon emissions.

Dry Process for Manufacturing of Cement
The pellets are baked hard in a preheating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process.

The cement kiln Understanding Cement
Wet process kilns. The original rotary cement kilns were called ''wet process'' kilns. In their basic form they were relatively simple compared with modern developments. The raw meal was supplied at ambient temperature in the form of a slurry. A wet process kiln may be up to 200m long and 6m in diameter.
