plants’ cleanup may create side-effect (AP)


The Omaha Public Power District's coal-fired power plant is seen in Nebraska City, Neb., Wednesday, Aug. 22, 2007. Scrubbers at the new plant being built on the site will inject chemicals to reduce airborne pollutants, but by doing so will change the composition of the ash produced in the process, and cut the ash's usefulness. The ash will end up in a landfill because it could not be used in cement, for example, because the interaction of the chemicals may keep the concrete from hardening. (AP Photo/Nati Harnik)AP – As the nation’s coal-fired power plants work to create cleaner skies, they’ll likely fill up landfills with millions more tons of potentially harmful ash.
