Coal The NEED Project

2021-4-26  Coal companies look for low-sulfur coal to mine. They work hard to remove sulfur and other impurities from the coal. Power plants install machines called scrubbers to remove most of the sulfur from coal smoke so it doesn’t get into the air. Other by-products, like the ash that is left after coal is burned, once were sent to landfills.
