There are many ways that energy consumption in a cement plant can be reduced. However, if the plant is already running the solutions may be difficult to implant retrospectively. The best time to Improve energy efficiency is at design phase. A thorough knowledge of the entire production process is needed and it would also be necessary to carry out a very detailed cost benefit analysis of the design options as some of them may cost more than the energy saved.

Modern cement plants should recirculate as much of the heat produced by the clicker burning process as possible to improve energy efficiency. Some is used to preheat the raw materials and some can be used to generate electricity which can help run the motors in the plant.
