TECHNO-NEWS * USA - Rice Concrete Can Cut Greenhouse Emissions
TX,USA -Discovery News Channel, by Michael Reilly -7 July 2009: -- Rice husks, which are rich in the important concrete ingredient silicon dioxide, could help generate a boom in environmentally friendly construction thanks to a new way of processing the husks for concrete use. Researchers including Rajan Vempati of Texas' ChK Group have found a way to make rice husk ash that is nearly carbon-free by heating the husks to 800 degrees Celsius in an oxygen-free furnace... "The process emits some CO2, but it's carbon neutral. Any that we emit goes back annually into the rice paddies," Vempati said... According to Jan Olek of Purdue University, who did not take part in the study. "I think the reason rice husk ash has had difficulty making it into mainstream applications is it typically comes with quite a high carbon content. If properly prepared, it could be a very useful, good material for efforts to limit emissions of carbon dioxide in the concrete industry"... This is a great green alternative to traditional cement mixtures, and it’s the perfect way to help developing countries construct sustainable buildings. But the idea of reusing rice has been around for a while... (Photo from ricegeneral)
