Use of Alternative Fuels in Indian Cement Industry: A Review

Abstract

The making of Portland cement is an energy concentrated process. It produces significant pollution and uses huge amounts of non-renewable energy. With growing pressures to cut greenhouse gas emissions due to cement manufacture, research and expansion of fuel alternatives and their effect on the manufacturing process have become an industry focal point. The intrinsic properties of sintering cement in a rotary kiln allows for a large number of fuels to be cooked which are normally forbidden for use as fuel in other processes. As world population increases, daily trash generated by human beings too goes up. Cement industry has a main role in solving garbage issues. It offers to keep fossil fuels and helps to shield environment by using different wastes as optional fuels. Hence, eliminating high energy wastes by using them as alternative fuels has been an extensive method in cement industries in nearly all developed countries. The most important energy used in cement industry is coal. Cement manufacturing releases a bunch of emissions such as carbon dioxide (CO2) and nitrogen oxide (NOx). It is projected that 5 percent of global carbon dioxide emissions creates from cement production. Make use of alternative fuels in cement manufacturing, therefore do not only give considerable energy cost reduction, but they also have major ecological profit of conserving non-renewable resources. The study report consist of usage of alternative fuel and its impact on environment, cement, clinker and process.
