During the last decades, the emission of dust from cement factories has been increasing alarmingly due to expansion of more cement plants to meet the growing requirement of cement materials for construction of buildings.

Air Pollution Aspects of Emission Sources: Cement

The intensity of atmospheric air pollution with cement dust in the vicinity of the cement plant exceed the dust intensity found in the inhabited region; it was 3-4 times as great as the limit of allowable dust concentration in at- mospheric air. Atmospheric air pollution with the cement plant discharges was detected 2000 m from the plant.

Guidance for reducing and controlling emissions of mercury

Plant-specific objectives for mercury emissions levels and reductions should be set based on the lowest level indicated by the following: • Local regulatory requirements • BAT/BEP guidance for the specific plant technology • Overall company targets • Plant-specific criteria. 2. Control of mercury emissions from the cement industry 1

US Cement Plant Using SCR Pollution Control Device

Sep 28, 2015 EPA has released the results of the first test of a full-scale Selective Catalytic Reduction (SCR) unit on a US cement plant and the numbers look good.. As many of you know, SCR is just an industrial-sized version of the catalytic converter in your car. It can capture up to 90% or more of the smog-forming pollution from a cement plant. In use on cement kilns since 2001, there are at least a

Cement Plant Pollution Harms Health < Moms Clean Air Force

Mar 08, 2012 The EPA estimates reducing fine particle pollution from cement plants will save up to 2,500 lives each year. The cement industry is fighting these rules. They say regulations would cost billions and force closures of some plants. However, federal regulator’s numbers are far lower than the industries numbers.

Environmental impact of concrete Wikipedia

Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne @ density of 2
