Nearly a century ago, most research into biofuels related to alcohol distilling was abandoned due to Prohibition. So instead of fueling cars with the byproducts of booze production, we’re still driving on dead dino juice. Now drunk Scots scientists at the Biofuel Research Center at Edinburgh Napier University have created a new butanol biofuel from the two most common by-products of Scottish whisky production. (Yes, I spelled it “whisky” on purpose, because it’s Scottish.)
The biobutanol is 30% more efficient than ethanol and is made from the pot ale (fluid leftover in the copper stills) and the draff (leftover grain husks). Both of these would otherwise be used in animal feed. Delicious. The Scottish malt whisky industry produces 1,600 million liters (422.6 million gallons) of pot ale and 187,000 tons of draff every year. DailyMail caught up with the lead researcher, Martin Tangney, who said they would be trying to distribute the biofuel by mixing it with petrol or diesel, with the butanol accounting for five to ten percent of the total.
Finally, a nexus between whisky and driving that won’t get me arrested.
