Researchers tinkering with bio-fuel (UK)

Scottish researchers are tinkering with bio-fuel � by adding waste from Scotch whisky to the mix.

The researchers have produced a type of fuel from distilled Scotch whisky, from Diageo's Glenkinchie Distillery.

The fuel uses "pot ale" � the liquid deposit from copper stills � and "draff" or leftover grain. Scientists claim it can be used in ordinary cars without altering the engines. Observers say the whisky bio-fuel has "earned a toast" from ecologists.

The fuel can also be used to make other green renewable biochemical�s, such as acetone, the main ingredient in most nail polish removers.

Supporters of the bio-fuel resulting from whisky byproducts say it could offer a new supply of revenue for one of Scotland's biggest industries, as well as helping to ease reliance on foreign oil.
