the pollution of the air around us. Air pollution is a concern to almost all people today, especially those who live in the metropolitan areas. Air pollution does not respect boundaries-state or nation. It affects people and plant far from its source and hence, a case of severe environmental consequences. The cement industry of the 21st century is confronted with disparate goals that …

Cement milling is the largest user of electric power on a cement plant, and because they can easily be started and stopped, it often pays to operate cement mills only during "off-peak" periods when cheaper power is available. This is also favourable for electricity producers, who can negotiate power prices with major users in order to balance their generating capacity over 24 …

liquid wastes, and the balance from natural gas, fuel oils, and used cement plants typically install air pollution control technologies called "scrubbers" to trap such pollutants in their exhaust gases. In addition, the limestone used to produce cement has "self-scrubbing" properties, which enable the industry to handle high-sulfur fuels. NEI estimates that, in 2022, the

the specific production processes, cement plants cause emissions to air and land (as waste). In specific rare cases, emissions to water may occur. Additionally, the environment can be affected by noise and odours. The key polluting substances emitted to air are dust, nitrogen oxides and sulphur dioxide. Carbon oxides, polychlorinated dibenzo-p-dioxins and dibenzofurans, total …
