(Telegraph) Scientists say they have created a new biofuel made from whisky by-products which could be used to help power cars currently on the road.

Edinburgh Napier University has filed a patent for the product, which can be used in ordinary cars without any special adaptions, scientists said. The biofuel has been developed over two years by the university’s Biofuel Research Centre.

As part of the research the centre was provided with samples of whisky distilling by-products from Diageo’s Glenkinchie Distillery in Tranent, East Lothian.

The biofuel uses the two main by-products from the whisky production process – ”pot ale”, the liquid from the copper stills, and ”draff”, the spent grains, as the basis to produce the butanol that can then be used as fuel. READ MORE
