Improving Energy Efficiency

Cement production requires a great deal of both thermal and electric energy.

Energy efficiency, defined as the total thermal energy consumed per tonne of clinker produced and as the total electric energy consumed per tonne of cement produced, is almost entirely a function of the technology applied in the production process.

Significant improvement in energy efficiency result from investments made in modern equipment and technology, as well as from the closure of old kilns that required very substantial amounts of energy.

Besides reducing production costs, improving energy efficiency also results in lowering greenhouse gas (CO2) emissions generated by fuel combustion, as well as by electric energy production in thermo power plants.
