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…
