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.”
