ENVIRONMENTAL – Welcome to Dangote Cement Plc

Using these modern heat recycling systems in this way, we can heat the raw material to about 900oC before it enters the kiln, thus reducing its time in the kiln itself and the amount of fuel used to convert it into clinker. This is good for costs and good for the environment because of lower carbon emissions involved in the production of our cement and the natural resource efficiency.
