Cement Industry
China produces nearly one-half of all cement in the world. With so much energy being expended, there is a comparable high potential for energy savings: 2.5 to 3 EJ per year may be saved (28–33% of all energy consumed in this sector) by various means, including waste energy recovery.

Energy and Cost Analysis of Cement Production Using the Wet and Dry
cement production is as low as $6 per tonne in China as opposed to $30 per tonne in Nigeria; this has contributed largely to the high and persistent rise in unit cost of ce- ment production. There is thus the need for the adoption of energy efficiency in cement production in Nigeria. Recently, there has been an increasing interest in using
