Craft beer brewer BrewDog announced today the commissioning of a £12 million green gas plant, which will use brewing waste to power the production of over 176 million pints of beer annually, and provide fuel for delivery vehicles.
At full capacity, the new facility at BrewDog’s Ellon, Scotland headquarters will reduce emissions by 7,500 tons, forming the centerpiece of the company’s £50m investment plans to slash carbon emissions per hectolitre of beer by 35% versus its baseline in 2019.
Sarah Warman, BrewDog’s Director of Sustainability, said:
“Our number one sustainability goal is to reduce emissions, and we want to lead the way for the entire brewing industry. We want all our teams to feel like the work they do supports our mission to protect the planet.”
The new plant uses wastewater from brewing with spent yeast and hops to be digested by bacteria to make biomethane. The anaerobic digester will support the company to recycle most of the 200 million liters of wastewater produced every year in the beer-making process and generate bio-methane to power its boilers. When fully operational, the digester will create 200 cubic meters of biomethane per hour, equivalent to 23,000 MWh of energy per year.
Surplus green gas produced will be used to power delivery vehicles and will be sold back to the grid. The company also plans to use the CO2 created by the digester to carbonate its beer.
“We’re not just here to make great beer – we’re making great beer that doesn’t cost the Earth. Our ambition is nothing short of making BrewDog beer the most planet-friendly beer on Earth, and we’ve taken giant strides towards that goal with our new bio-energy plant.”
