Thermal energy in cement plant

Cement manufacturing requires raw materials to be heated to 1450C and is thus rather energy intensive, even if thermal energy only accounts for approximately 35% of the cement industrys CO 2 emissions Continuous improvements to production facilities have almost halved our energy use since the 1960s
