Pollution From Cement Industry

a review on environmental and health impacts of cement,cement industry is potential anthropogenic source of air pollution. it has estimated that cement production originates about 5% of global manmade co 2 emissions [13]. the typical gaseous emissions to air from cement production include nox, sox, co, co 2, h 2 s, vocs, dioxins, furans and particulate matters [14], [15], [16]. these major pollutants can be classified in.cement industry challenges pollution cuts that would save,the portland cement association (pca) has filed a lawsuit challenging the u.s. environmental protection agency’s decision to cut toxic air pollution from cement kilns. according to the epa, these cuts would avoid up to 2,500 premature deaths every year and result in.laying the foundation for a zero-carbon cement industry,the cement industry alone is responsible for about a quarter of all industry co 2 emissions, and it also generates the most co 2 emissions per dollar of revenue (exhibit 1). about two-thirds of those total emissions result from calcination, the chemical reaction that occurs when raw materials such as limestone are exposed to high temperatures..making cement production less polluting,large amounts of carbon dioxide and nitrous oxides are produced in manufacture of cement. della m roy of the materials research laboratory of pennsylvania state university estimates 30 per cent of limestone used in cement production becomes carbon dioxide..
