Glenfiddich converts whisky residue into biogas fuel



Glenfiddich has launched a new sustainable transport model, making it the first spirits brand to convert its whisky waste into fuel for its fleet.

Parent company William Grant & Sons launched the closed system at the Glenfiddich distillery at Dufftown, converting the residues from its distilling process into a biogas.

The technology converts production waste into an ultra-low carbon fuel (ULCF) gas that produces minimal carbon dioxide and other harmful emissions.

Fuelling stations have been installed at the distillery and the biogas is now powering specially converted trucks that handle the transportation of the Glenfiddich spirit at all stages of its production, through to bottling and packaging – a journey that covers four sites in central and western Scotland.

William Grant & Sons now plans to scale-up the decarbonising benefits of the closed-loop process across its entire transport fleet and its supply chain.

It is also planning to make the technology available across the Scottish whisky industry to support the decarbonisation of transport, in line with UK and Scottish Government’s net zero targets.

William Grant & Sons’ distilleries director Stuart Watts said: “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 biogas fuel to power its trucks, and finally to be the first to install a biogas truck fuelling station supplied by our on-site renewable energy facility.”

He claimed the biogas will help reduce its carbon dioxide emissions by more than 95% and other harmful particulates and greenhouse gas emissions by up to 99%, compared to diesel and petrol trucks.

“Each truck should displace up to 250 tonnes of carbon dioxide annually, which has the same environmental benefit as planting up to 4,000 trees every year – the equivalent of displacing natural gas, a fossil fuel, from 112 households.”
