Car biofuel from whisky by-products
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
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
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 yesterday.
"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
"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 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."
