Dutch Brewery, Grolsch (part of Asahi Europe & International), is moving closer to its carbon neutrality goal after kickstarting plans to produce biomethane using HoSt technology.
By the end of 2022, more than two-thirds of Grolsch's heat demand will be met by sustainable heat from waste management company Twence, delivered through a new underground pipeline. With this heat supply, not all of Grolsch's biogas can be used directly for its own heat demand anymore and so the biogas produced will be upgraded to biomethane in a newly built biogas upgrader on the brewery's site.
The new technology, which will be installed by Dutch bioenergy company HoSt, will take the biogas from the Grolsch wastewater treatment plant and will produce over 1 million Nm3 of biomethane annually - equivalent to the gas needs of approximately 700 households.
Susan Ladrak, Sustainability Manager at Grolsch, said: “With the arrival of the heat pipeline, it is necessary to give the biogas another use, in which it is still optimally utilised: biomethane is a sustainable, proven efficient application.
“We are very proud of this step as part of our energy transition, in combination with the projects of our sustainable heat purchase and 100% green electricity choice. All of these initiatives bring us a big step closer to our goal of being a carbon neutral brewery by 2025!"
