How Tennent's Brewery Now Collects & Recovers Its Own CO2
Tennent’s Brewery, a Scottish-based brewery, relied on purchasing CO2, which can pose challenges, such as the environmental impact of transporting CO2 to the brewery and, depending on the CO2 merchant market, volatile market prices and supply risks.
Tennent’s required a fully end-to-end CO2 collection and recovery system, allowing them complete autonomy over recovering their CO2 and the capability to utilize it back into the beer production process.
The Solution: Pentair, a process-oriented solution provider with a substantial worldwide footprint in carbon recovery solutions, supplied a complete package that included the collection, recovery, vaporization, and storage of CO2.
Results: Recovers over 4,200 tonnes of its own CO2, repurposing 95% of this CO2 back into its brewing processes and eliminating the need to source CO2 from third-party sources[1].

Alasdair Hamilton, Engineering Manager, C&C Group, Tennent’s Brewery, comments, “As an environmentally conscious brewery, it was a natural decision to utilize the CO2 generated in our fermentation process and incorporate it back into our brewing.
Thanks to Pentair's expertise, we could implement the technology. From start to finish, our experience with Pentair was exceptional. They recommended a comprehensive system that allows us to recover our CO2 and reintroduce it back into our brewing process through a collection capability. With this system in place, we can avoid the fluctuations of the CO2 market and focus on consistent and reliable operations.
