Scottish firm wins £11m grant to make fuel from whisky waste

One of three biofuels producers to share in a £25 million funding pot awarded by the Department for Transport (DfT), the Edinburgh-based firm will use the cash to build a biofuel facility that will be operational by December 2018. The company claims that it will produce at least 1 million litres of biofuel - capable of powering cars - every year.

Prof Martin Tangney, the company’s founder and president, explained that the facility will be used to carry out or acetone-butanol-ethanol (ABE) fermentation.

This process uses bacterial fermentation to produce biofuels from carbohydrates such as starch and glucose. It was originally devised in the UK at the start of the last century to produce acetone for explosives used in the First World War, but was phased-out in the 1960s due to competition from the petrochemical industry.

“Our aim”, said Prof Tangney, “is to reintroduce that process but in a modern context which allows us to use the leftovers from the whisky industry to create a fuel source that contributes to the low carbon future we all want.”
