One for the road: Whisky waste to help develop biofuel for cars

Thursday, 19 August 2010

19 August 2010;dailypioneer.com:London:Whisky lovers have another excuse to enjoy a dram — scientists in Scotland have unveiled a biofuel to help power cars developed from the by-products of the distillation process. Researchers at Edinburgh Napier University have developed the biofuel and filed a patent for the product, which they said could be used to fuel ordinary cars without any special adaptations. The biofuel, which has been developed during a two-year research project, uses the two main by-products from the whisky production process. These are “pot ale”, the liquid from the copper stills, and the spent grains called “draff”, as the base to produce butanol which can then be used as fuel. “The new biofuel is made from biological material which has been already generated,” Martin Tangney, who is leading the research said on Tuesday. “Theoretically it could be used entirely on its own but you would have to find a company to distribute it.” He added the most likely way the biofuel would be used was by blending five or 10 per cent of the product with petrol or diesel. “Five or 10 per cent means less oil which would make a big, big difference,” he said. The biofuel “potentially offers new revenue on the back of one of Scotland’s biggest industries,” added Tangney. Richard Dixon, the Scotland director of environmental campaign group WWF, praised the new product, saying unlike other biofuels it could be made without causing “massive environmental damage to forests and wildlife. “Whisky-powered cars could help Scotland avoid having to use those forest-trashing biofuels.”
