Waste from distilling alcohol can now be converted into renewable energy.
Scotland is known for its rich culture and history of malt whiskey, and now scientists are discovering ways to turn the by-products of this alcoholic beverage into usable fuel. Celtic Renewables, an innovative start-up company in Scotland, has developed a “next generation biofuel” by reusing ingredients like draff and pot ale that are often considered as waste when brewing whiskey.
Celtic Renewables hopes this new bio-butanol fuel will reduce oil consumption and carbon emissions. The company has already received the support of the Scottish Whiskey Association and the government in Scotland to commercialize the process in producing the bio-butanol.
