When it comes to biofuels, most people think of ethanol obtained from crops or biodiesel made out of fat and other natural oils. But using only crops to create biofuel won’t cut it and we should also turn to creating waste into the liquid that powers our lives. One such wastes is the draff coming out of the whiskey distillery.
Edinburgh-based startup company Celtic Renewablesfound a way create biobutanol out of draff and pot ale. The alternative fuel can be used to power pretty much every internal combustion engine without modifications, or can be blended with regular fuels.
The company’s CEO Mark Simmers expects to start commercial scale production in 2015, as it’s currently working with the Tullibardine whisky distillery in Blackford, Scotland.
