Cement accounts for 83% of total energy use in the production of nonmetallic minerals and 94% of CO2 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process.
