The European cement industry has steadily increased its use of alternative fuels a sevenfold increase since 1990 to over 7 million tonnes in 2010. Together with energy recovery, the fuel ashes are entirely used as raw material in cement production. To increase use of alternative fuels, access to waste and biomass must also increase.
Malawi. Switching to crop residues as an alternative energy source for energy-intensive industries such as cement manufacturing is hampered by uncertain-ties in crop residue availability, cost and quality. In this study, future demand for energy and availability of crop residues was assessed, based on data at the sub-national level.
May 09, 2012 Cement manufacturing is highly energy- and emissions-intensive because of the extreme heat required to produce it. Producing a ton of cement requires 4.7 million BTU of energy, equivalent to about 400 pounds of coal, and generates nearly a ton of CO 2. Given its high emissions and critical importance to society, cement is an obvious place to ...

Alternative Fuels in Cement Manufacturing. The use of alternative fuels in cement manufacturing, therefore do not only afford considerable energy cost reduction, but they also have significant ecological benefits of conserving non-renewable resources, the reduction of waste disposal requirements and reduction of emissions. 247 Live Chat
Sep 06, 2011 This report provides a comprehensive overview of the current literature on cement manufacturing with respect to emissions control and the use of alternative fuels. Its powerful synthesis is useful for both academic researchers and practitioners engaged with the cement industry or waste-to-energy efforts. Download the full 139-page Systematic ...
Cement manufacturing is an energy-intensive process that depends on carefully balanced chemistry and physics. Cement plants run continuously, typically 24 hours a day, seven days a week, and generating and maintaining kilns at the high temperatures required to create clinker involves the combustion of significant quantities of fossil or ...
