The company said it has installed fuelling stations at its Dufftown distillery in north-eastern Scotland which use technology developed by its parent company William Grant and Sons. It will convert its production waste and residues into an Ultra-Low Carbon Fuel (ULCF) gas that produces minimal carbon dioxide and other harmful emissions.
Glenfiddich said the transition to using fuel made from the distillery’s waste product is part of a “closed-loop” sustainability initiative.
