RabbitWho writes "It gives a whole new meaning to the phrase 'one for the road.' Whisky, the spirit that powers the Scottish economy, is being used to develop a new biofuel which could be available at petrol pumps in a few years. This biofuel can be produced from two main by-products of the whisky distilling process – 'pot ale,' the liquid from the copper stills, and 'draff,' the spent grains. Copious quantities of both waste products are produced by the £4bn whisky industry each year, and the scientists say there is real potential for the biofuel, to be available at local garage forecourts alongside traditional fuels. It can be used in conventional cars without adapting their engines. The team also said it could be used to fuel planes and as the basis for chemicals such as acetone, an important solvent."
