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.
