Industrial Baghouse Filter Bags for the Cement Industry | Gore

Emissions control is a hot topic in the cement industry. Cement plants are driven by throughput, but if they fail to comply with the new NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations, production could be stopped immediately, introducing a slew of cost factors that affect plants' bottom line.

Q&A: Why cement emissions matter for climate change ...

If the cement industry were a country, it would be the third largest emitter in the world. In 2015, it generated around 2.8bn tonnes of CO2, equivalent to 8% of the global total – a greater share than any country other than China or the US.. Cement use is set to rise as global urbanisation and economic development increases demand for new buildings and infrastructure.

How Cement Is Made

Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
