Alternative Fuel Use in Cement Manufacturing
Alternative Fuel Use in Cement Manufacturing 6 Emissions from cement production More than 50% of the total CO2 from cement production results from the chemical reaction that converts limestone into clinker, the active ingredient in cement. This chemical reaction accounts for approximately 540 kg CO2 per tonne of clinker.

ERNEST ORLANDO AWRENCE BERKELEY NATIONAL .
The production of cement is an energyintensive process. Annually the cement industry spends over 1 billion energy purchases. The production of cement results in the emission of carbon dioxide from both the consumption of fuels and from the calcination of limestone. This report briefly describes the various stages in the cement production process.
