Introduction. The cement sector is responsible for about 7% global anthropogenic CO2 emissions (IEA, 2018). Two-third of the CO2 emission originate from calcination of limestone while one-third come from the combustion of fuel. It is, therefore, impossible to reach CO2 emission targets with fuel switching alone.
