WASTE FROM Diageo’s whisky production at its Scottish factory will be turned into energy which powers the distillation process.

The anaerobic digestion plant is expected to generate 2 million cubic metres of biogas a year. Designed by Clearflue, it will convert the waste outputs from the distillation process - called pot-ale and draff - into thermal energy. This renewable heat can then be used to power further distillation, whilst reducing waste disposal costs.

 

The global drinks giant already uses Clearfleau technology at its Dailuaine malt distillery in 2013. However, a Clearfleau spokesperson said that without continued government support, projects which help energy intensive business sectors, such as the drinks industry, embrace the circular economy by adopting renewable energy generation could be at risk.
