CNBM Group decarbonised its cement plants by recovering waste heat to generate power that is then used in cement plants, which is called the WHR system. The total capacity of all WHR systems within CNBM’s cement business is 2,150 MW in 2020, and generated 9.04 billion KWH power a year, which means it is reducing 2.91 million tonnes CO2 emission in the year.
