BrewDog AD facility plans recommended for approval

BrewDog’s plans to build an anaerobic digestion (AD) facility, water treatment plant, CO2 recovery plant and associated energy generation centre have been recommended for approval.

According to the Evening Express, the idea behind the proposal is to help BrewDog, a multinational brewery and pub chain, to become the ‘world’s most sustainable drinks firm’ and become carbon neutral by 2022.

Aberdeenshire Council’s report on the plans said: “The application seeks full planning permission for the erection of an AD plant, a water treatment plant, an associated energy generation centre, and a CO2 recovery plant at site 8 BrewDog, Balmacassie Commercial Park, Ellon.

“The purpose of the proposed development is for the treatment of organic processed liquid (OPL) to supply on-site energy while cutting disposal costs and the business’s carbon footprint.

“Liquid feedstock comprising wash-waters and OPL are currently hauled off-site for land application. It is now proposed that the liquid feedstock would be transferred as it is produced from the brewery via local pump stations to existing and new proposed balance tanks. These would feed two new anaerobic reactors, which are also fed by a heat exchanger and chemicals and nutrients to aid bio-growth.

“There are only three outputs from the process: biogas to be upgraded for grid entry (CO2 removed from the gas would be used to replace imported CO2), clean water that would be discharged to the River Ythan or recycled for reuse on-site, and stable, nutrient-rich biosolids that can be applied as nutrients on land used to supply grain to the distillery.”
