The Environment

Burning coal used to produce a lot of carbon dioxide and sulfur emissions that polluted the air. By removing the sulfur and other impurities from coal, it burns cleaner today and is better for our environment.

Today, mining companies look for low-sulfur coal to mine.

Coal-fired power plants now have equipment installed called scrubbers. Scrubbers remove most of the sulfur from the smoke that is produced by burning coal so it does not get into the air.

The ash that is left over from the burned coal is also recycled. In earlier years the ash was used for landfills, but now it is being used to make materials to build roads and cement products. Today the ash is also being used to make ocean reefs for marine animal habitats.

Because we have such a large supply of coal here in the United States, researchers are busy working on ways to remove even more carbon dioxide and sulfur from the emissions. This will make getting energy from coal even cleaner for our environment.
