British multinational alcoholic beverage company Diageo yesterday (17 August) began operating an anaerobic digestion (AD) facility at its Glendullan distillery in Speyside, Scotland.
The move follows completion of a high-rate AD facility at the Dailuaine malt distillery (also in Speyside) in 2013. Diageo then commissioned AD company Clearfleau to build the second facility at its Glendullan plant. It uses co-products from the distillation process as well as receiving feedstock from other distilleries in the Dufftown area, fed to the plant in a recently completed pipeline to reduce local truck movements.
