Whisky Maker Delivers with RNG
Glenfiddich is turning its own Scotch whisky waste into renewable natural gas for use in its delivery trucks.

You may know Glenfiddich for its award-winning single malt Scotch whisky. What you may not know is its commitment to greenhouse gas emission reductions. The fleet is using waste from the whisky-making process to produce its own renewable natural gas and use it in its delivery trucks.
Glenfiddich is leading a sustainability initiative to address the Scotch Whisky Association’s climate change targets of net zero GHG emissions by 2040. To obtain these reduction levels, Glenfiddich is using RNG derived from its production waste residues to power its fleet of delivery trucks, equipped with Hexagon Agility’s ProRail compressed natural gas fuel systems.
The technology was developed by its parent company William Grant & Sons.
“It has taken more than a decade for Glenfiddich to become the first distillery to process 100% of its waste residues on its own site, then to be the first to process those residues into RNG fuel to power its trucks, and finally to be the first to install an RNG truck fueling station supplied by our on-site renewable energy facility,” said Kirsty Dagnan, William Grant & Sons’ Dufftown Site Leader.
“We are proud to have achieved these renewable energy breakthroughs in our industry, and to be working with a pioneering partner such as Hexagon Agility as we scale up the de-carbonizing benefits of this closed-loop process across our entire transport fleet.”
RNG, made from organic waste, is a pipeline quality gas fully interchangeable with CNG. The RNG produced by Grissan will reduce GHG emissions up to 95% when compared to diesel and other fossil fuels.
“We congratulate Glenfiddich in becoming the first whisky distillery to process 100% of its waste residues into RNG to power its trucks,” said Eric Bippus, Hexagon Agility’s senior vice president of global sales and marketing. “RNG is a game-changer, not only for whisky distilleries but also for the heavy-duty trucking industry looking for the lowest-emission fuel available today.”
