Development of an Efficient Procedure for Sustainable Low Carbon Cement Manufacturing Process
Abstract:
The consumption of Portland cement for the production of concrete is rapidly increasing because of the remarkable growth in the construction worldwide. Cement production is an energy intensive process. The energy consumption by the cement industry is estimated to be about 5% of the total global industrial energy consumption. Manufacturing process of cement consumes enormous quantities of raw materials from limited natural resources at a high rate and leads to their depletion. Due to the dominant use of carbon intensive fuels such as coal, the cement industry is a major emitter of carbon dioxide and other air pollutants. The cement industry contributes about 6 % of global carbon dioxide emissions which is the primary source of global warming. In addition to carbon dioxide emissions, significant amount of nitrogen oxides, sulphur dioxide, carbon monoxide, hydrocarbons and volatile organic compounds are emitted during cement manufacturing and causes severe environmental issues. In this regard, effective control techniques for reduction in carbon dioxide emissions from modern cement industry and an efficient procedure to achieve sustainable cement manufacturing process are discussed in this paper.
