Whisky helps replace petrol

A car has been fuelled by whisky for the first time!

Don’t worry, it’s not the alcoholic drink itself that is being used for this new project, just the leftover waste from the fermentation process.

Scottish Company Celtic Renewables has successfully fuelled a car using biobutanol – a biofuel made from draff. Draff is the sugar-rich kernels of barley which are soaked in water to facilitate the fermentation process for whisky. The fuel also uses pot ale, a yeasty liquid that is left over after distillation.

With 750,000 tonnes of draff and 2 billion litres of pot ale being produced in Scotland every year, it sounds like a great idea.

Professor Martin Tangney, the company’s founder and President, said: “This is the first time in history that a car has ever been driven with a biofuel produced from whisky production residues.

“It is fitting to do this historic drive in Scotland, which is famous not just for its world-renowned whisky but also for being a powerhouse for renewable energy.”

The downside of this of course is that if this scheme becomes a big success, we will all have to drink more whisky in order to make enough waste products to run all of our cars! Oh well…
