According to 3, the efficiency of the steam turbine process is around 25–30%, meaning only a 1/4 of the waste heat is transformed into electrical energy in the cement industry. The thermal energy content of cooler waste gases was found to be 784 kJ/kg of clinker. However, only 435 kJ/kg of clinker can be utilized for power generation.
The cement industry is an energy intensive industry consuming about 4 GJ per tonne of cement produced. A thermodynamic analysis for cogeneration using the waste heat streams is not easily available. Data from a working 1 Mt per annum plant in India is used to obtain an energy balance for the system and a Sankey diagram is drawn.

frequently assumed to have no energy requirement for their manufacture and their feedstock energy (energy inherent to the material) is normally associated with the finished product not the used product. Hence, when alternate fuels that are typically disposed of in landfills are utilized as fuels they provide a source of "free" energy.
