Whisky by-products used to create biofuel
Researchers at Edinburgh Napier University have filed a patent for a new biofuel made from whisky by-products.
Funded by Scottish Enterprise's Proof of Concept programme, the two-year project created the biobutanol fuel using by-products from Diageo's Glenkinchie Distillery.
The scientists claim that the fuel gives 30 per cent more output power than ethanol and can be used in vehicles without any adaptation.
Components of the fuel include pot ale - liquid harvested from the copper stills - and draff, which is spent grains.
Professor Martin Tangney, director of the Biofuel Research Centre at Edinburgh Napier University, said that the researchers are taking a new approach to biofuels by not growing crops specifically for fuels.
"This is a more environmentally sustainable option and potentially offers new revenue on the back of one Scotland's biggest industries," he added.
The UK is committed to producing ten percent of transport energy from biofuels by the year 2020 under the European Renewable Energy Directive. This will help contribute to the target of a 20 percent cut in emissions in the next decade.
