A peg of scotch whisky can reduce carbon emission too as scientists in Scotland have developed a biofuel from the by-products of whisky which can be used to power cars.

Edinburgh Napier University has filed a patent for the biofuel which has been created in two years by the university's Biofuel Research Centre. The university now plans to create a "spin-out" company to take the fuel to the market, according to Daily Mail.

According to the researchers, two by-products from the whisky production process - "pot ale", the liquid from the copper stills, and "draff", the spent grains - are used to produce butanol which can be used as fuel.

Martin Tangney, who is leading the research and is director of the Biofuel Research Centre, said: "The new biofuel is made from biological material which has been already generated.

"This is a more environmentally sustainable option and potentially offers new revenue on the back of one Scotland's biggest industries. We've worked with some of the country's leading whisky producers to develop the process," Martin said.
