Marketing coal ash, slag, and sludge

Investigates the selling of by-products of coal-fired power generation--fly ash, bottom ash, boiler slag, and scrubber sludge--by utilities for use in highways, parking lots, cement, roofing, bricks, and blocks. Points out that the EPA has drafted tough new regulations for solid-waste storage, transportation, and disposal that may soon cost power plants $25-$40 a ton to dispose of wastes. Reports that the EPRI is studying high-volume by-product applications that have low technology requirements (e.g. fly ash for use in highways, parking lots, and utility construction) and medium-volume, medium-technology applications (e.g. by-products used for cement manufacture, asphalt, blocks, bricks, roofing granules, and wallboards). Reveals that EPRI plans to eventually identify a representative set of perhaps half a dozen basic fly ashes, characterize them, do proportion studies of existing concrete mixes (including those with fly ash in them), and then develop guidelines for fly ash proportions in concrete.
