Green Technology Converts Waste Ash from Power Stations into Minerals
Two British scientists, John Watt and Philip Michael, have launched technology that will convert the controversial tonnes of waste-ash from Britain's coal-fired power stations into valuable minerals useful to industries including cement, car and aviation manufacturers.The first plant for RockTron, which is now finished and on-line in Fiddlers Ferry coal-powered station in Cheshire, UK, will transform 800,000 tonnes of ash per year into five valuable minerals. It will also cut the cost of dumping the ash in land-fill sites.
The most significant of the so called eco-minerals are solid glass spheres called aluminio-silicates that could reduce CO2 emissions in cement making - one of the dirtiest processes - by an estimated 400,000 tonnes a year in Britain alone. Another by-product are hollow glass spheres that can be used by automotive and aviation industries to make lighter cars and planes.
