now, a company in scotland is exploring a solution that seems a little unusual. the bbc�*s tim allman has the story. there is apparently an old proverb that says "what whisky will not cure, there is no cure for". but, does its magical properties extend to saving the environment? well, maybe. here at the glengoyne distillery, they have been making whisky for almost 200 years. but it is what they throw away that could turn out to be so useful. from these malted barley grains, a biofuel is created that can power this car. this is made from living carbon, from the residues of an industry that is one of the most important industries in the scottish economy and we can take their residue and turn them into something that we need right now made from sustainable resources. what they end up with is acetone, butanol and ethanol, chemicals used in everything from fuel and food production to medicine and cosmetics.
