(New York Times 12-24-08) - What may be the nation’s largest spill of coal ash lay thick and largely untouched over hundreds of acres of land and waterways Wednesday after a dam broke this week, as officials and environmentalists argued over its potential toxicity.
(Science Centric 11-26-08) Each year, coal-burning power plants, steel factories and similar facilities in the United States produce more than 125 million tons of waste, much of it fly ash and bottom ash left over from combustion. Mulalo Doyoyo has plans for that material. An assistant professor in Georgia Tech's School of Civil and Environmental Engineering, Doyoyo has developed a new structural material based on these leftovers from coal burning.
(Power Engineering 4-06) One man’s trash is another man’s treasure. Although the by-products created during the coal combustion process are not exactly trash, coal-fired power plant owners must find either a viable use for them or a place for their disposal. In many cases, these by products can be used by other industries, making them at least a valuable resource.
(Science Daily 3-5-06) Filling mines with the residues of coal combustion is a viable way to dispose of these materials, provided they are placed so as to avoid adverse health and environmental effects, says a new congressionally mandated report from the National Academies' National Research Council.
