4. MATERIALAND ENERGY BALANCE

Most of the balance is lost from the process as carbon dioxide emission to air in the calcination reaction (CaCO3 → CaO + CO2). The cement industry is an energy intensive industry with energy typically accounting for 30-40% of production costs (i.e. excluding capital costs). Various fuels can be used to provide the heat required for the process.
