Spent Grains from Whisky and Beer Production Potential Source of Biofuel to Power Scottish Cars

If anyone can turn whisky into gasoline it's the Scots. With the help of a grant researchers at Abertay University are examining how to make biofuel from spent grain.

The researchers hope to find a way to reuse the residue from whisky and beer production. The Scottish scientists hope to find an economical way to create bioethanol, which burns cleaner than petroleum based fuel.

Professor Graeme Walker will lead the year-long study, which has to overcome challenges in converting spent grain into fuel. The process is more difficult than producing bioethanol from virgin materials. Currently spent grain from stills is either used for animal feed or discarded.
