BrewDog to cut carbon emissions with £12 million bio-energy plant

BrewDog has commissioned a £12 million green gas plant that will power the production of over 176 million pints of beer each year, which would result in 7,500 fewer tons of carbon emissions annually when the facility in Ellon, Aberdeenshire, is running at full capacity.

The company will combine wastewater with spent yeast and hops from its brewing process at the plant, which will be 'digested' by bacteria and converted to biomethane. BrewDog intends to carbonate its beer with CO2 produced by the digester in the coming years.

The anaerobic digester will allow the craft beer maker to recycle the majority of the 200 million liters of wastewater generated each year during the brewing process while also producing bio-methane to power the brewery's boilers.

Sarah Warman, BrewDog’s director of sustainability, commented that their ambition is to make their beer the most planet-friendly on Earth, and they’ve taken giant strides towards that goal with their new bio-energy plant.
