Harnessing waste heat to decarbonise cement and steel

That's a lot of heat… yet in many cement plants, much of it still disappears via flue gases and surface dissipation – as much as 40%-45% of what's put in. This is where waste heat recovery (WHR) comes in. The waste heat of the kiln and other areas of the plant can be reused, providing up to a third of the plant's power requirements.
