You may have read the news we shared earlier this year where Tröegs had begun construction on a new 15,000 square foot space to house their canning line, as well as the addition of new parking. But the construction doesn’t stop there. The central PA brewery has also been working hard on CO2 self-sufficiency.
In the latest Tröegs blog the brewery shared that the installation of “new tanks will allow us to become ‘CO2 self-sufficient'” and that “all of the CO2 needed in our processes will be produced by our beer fermentation.”
If you have visited the brewery recently, you may have noticed these tanks being installed toward their outdoor mural.
As the report from the brewery states the completion of this project is set to happen in three phases. Phase one was a thorough analysis of all CO2 needs used in the brewing process. “We started last year by looking at every way we use CO2 and asked ourselves if we could maintain the same quality standards while using less CO2,” says brewmaster John Trogner of the initial phase. Coupled with installing a Nitrogen Generation system, phase one resulted in a 25-30% reduction in CO2 needs.
The setup and arrival of the new tanks is the start of phase two. These tanks, once operational, will allow Tröegs to store 50 tons of CO2. “That equates to about a month of our CO2 use,” says Trogner about the brewery’s usage.
As of this writing, the brewery is working towards phase three which is the installation of a carbon capture system. As the brewery shares, their fermentation produces roughly one million pounds of CO2 annually. The goal will be to harness this production and store it for future use. “This should be enough to cover our yearly needs and make us self-sufficient,” says Trogner.
The expectation is for the project to be completed and online by the end of Quarter 2 in 2023. You can follow the brewery’s blog online, or on Facebook, Instagram, and Twitter to keep up with all of their latest news.
