Researchers in Scotland develop whisky-based biofuel

Daily Mail : Scientists at Edinburgh Napier University have developed a new biofuel made from whisky byproducts. It uses the two main byproducts from whisky distillingâmdash;pot ale (the liquid from the copper stills) and draff (the spent grains)âmdash;to produce butanol. Although the fuel could be used in its pure form, the most likely use will be as a blend with gasoline or diesel. As whisky is one of Scotland’s biggest exports, creation of the new biofuel would use up the copious waste products and reduce the environmental impact of whisky production.
