We have put forward two proposals that reflect different approaches to managing the disposal of coal ash and are inviting public comments on these two options.
 

From Waste to Efficiency

(Business Lexington 4-20-2010) For decades, fly ash, one of the residues generated in the burning of coal, especially at coal-fired power plants, was released into Kentucky's skies.

Recycling Transforms Fly Ash Into Eco-Minerals

(Engineering Live 4-27-2010) RockTron's new plant at Fiddler's Ferry in Widnes, Cheshire, UK (Fig. 1), can recycle 800,000 tonnes of fly ash a year. It is designed to process both fresh and stockpiled fly ash, effectively solving the problems of large-scale waste storage and removal, site remediation and conservation of natural resources. This GGBS, or CEM I (Portland cement (PC)) substitution proposition, allows companies to cut their costs, increase their margins and maintain their bottom line. RockTron is currently negotiating new plants in the US, Malaysia and Russia.
