Glenfiddich uses own whisky waste to fuel trucks:

Scotch whisky maker Glenfiddich has announced that it will convert its delivery trucks to run on low-emission biogas made from waste products from its own whisky distilling process.

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. Stuart Watts, distillery director at William Grant, said traditionally Glenfiddich has sold off spent grains left over from the malting process to be used for a high-protein cattle feed.

However, through anaerobic digestion – where bacteria break down organic matter, producing biogas – the distillery can also use the liquid waste from the process to make fuel and eventually recycle all of its waste products this way.

[...] Last year, the Government announced a £10m fund to assist UK distilleries with transitions to low-carbon fuels, such as hydrogen and biomass.
