One For The Road: Glenfiddich Uses Whisky Waste To Fuel Trucks

Glenfiddich said it has installed fuelling stations that converts its production waste and residues into an Ultra-Low Carbon Fuel gas that produces minimal carbon dioxide and other harmful emissions.

Scotch whisky maker Glenfiddich has begun converting its delivery trucks to run on low-emission biogas made from waste products from its own whisky distilling process as part of a "closed loop" sustainability initiative, it said on Tuesday. Glenfiddich said it has installed fuelling stations at its Dufftown distillery in north-eastern Scotland that use technology developed by its parent company William Grant & Sons to convert its production waste and residues into an Ultra-Low Carbon Fuel (ULCF) gas that produces minimal carbon dioxide and other harmful emissions. Stuart Watts, distillery director at family-owned William Grant & Sons, said traditionally Glenfiddich has sold off spent grains left over from the malting process to be used for a high-protein cattle feed. But through anaerobic digestion - where bacteria break down organic matter producing biogas - the distillery can also use liquid waste from the process to make fuel and eventually recycle all of its waste products this way.
