Cement production, responsible for about 8 % of global carbon dioxide (CO 2) emissions [2], has widely been identified as a primary target for progressive decarbonisation efforts. In the conventional cement production process, CO 2 emissions primarily result from the production of clinker, the main component of Portland cement [3].
Alternative Fuels in Cement Manufacturing | IntechOpen
In 1995 the world production of cement was about 1420 million tonnes (Cembureau, 1997). Cement production is an energy-intensive process consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced, which accounts for 30 – 40 percent of production costs (Giddings et al., 2000; EC, 2001). Worldwide, coal is the …
