The cement industry is actively seeking to increase the use of alternative fuels for cement production. Both to decrease energy dependence on conventional fossil fuels and to mitigate negative environmental impact. One of these alternatives is waste-to-energy. Many cement plants generate energy through incineration of waste. Hazardous waste can ...

Methods of Manufacturing Process of Cement. At present Portland Cement is manufactured by two processes, Dry Process, and Wet Process. The main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.

Cement is the largest man-made material in the world. With the global population set to hit 8 billion soon, the demand for cement is about to skyrocket to unprecedented levels. However, cement manufacturing is linked inexorably to the ongoing phenomenon of climate change. Greenhouse gases like CO2 trap the sun's heat and cause the average temperature to increase in the world.
