Energy Use – Cement

For integrated cement plants, energy in the form of heat is required to raise the kiln temperature to over 1,450 degrees Celsius required to produce clinker. This heat is predominantly generated by coal and natural gas, and to a lesser extent by diesel oil. In total Australian cement producers used around 21 petajoules of thermal energy, up 3 per cent year-on-year and down 23 per cent since ...
