Brewing Sustainably: Pure Project Recaptures Over 74,500 Pounds of CO2 with On-Site CO2 Recovery System

SAN DIEGO, CA: Pure Project Brewing has taken another major step in its commitment to environmental stewardship with the installation of a new CO2 recapture system from Dalum Beverage Equipment, a Denmark-based pioneer in craft-scale carbon recovery technology. The state-of-the-art equipment allows the brewery to capture biogenic CO2 produced naturally during fermentation, which is then cleaned, condensed, and reused on-site for producing and serving beer.

Since installing the equipment in February 2026, Pure Project has recaptured and reused 34,000 kg (over 74,500 lbs) of CO2 gas, which would have otherwise been released into the atmosphere. To put this impact in perspective, the reduction is equivalent to the emissions from burning nearly 3,850 gallons of gasoline.

To celebrate this sustainability milestone, Pure Project has teamed up with Dalum and fellow San Diego craft brewery Societe Brewing Company to create Closed Loops, a collaborative hazy IPA brewed with recaptured CO2. The launch of Closed Loops coincides with Societe's successful integration of Dalum’s CO2 recapture equipment into its own brewing facility, laying the groundwork for a meaningful craft brewing partnership centered on sustainable innovation.

“We're proud to see our CO2 recovery technology playing a role in a collaboration like this between two staple San Diego breweries," said Ashley Hanes, U.S. Sales and Service Representative at Dalum Beverage Equipment. "It's especially rewarding when sustainability work shows up in a beer people are excited to drink. Pure Project and Societe have been great partners in putting the technology to work, and we're glad to celebrate this release alongside them."

The shared commitment to environmental technology inspired the collaboration behind Closed Loops hazy IPA. By recapturing the CO2 on-site, both breweries significantly lower their dependence on commercially produced CO2, further reducing emissions from freight transport and creating a closed-loop system directly inside each brewery's brewing facility.

"When we started this project, we knew we wanted to do better for the environment, but recapturing over 74,500 pounds of CO2 in such a short window has really shown us what is possible in making brewing operations more sustainable," said Winslow Sawyer, Co-Founder and Brewer at Pure Project. "Running a true closed-loop system in our own brewery has been a long-time goal of ours, and sharing this moment and win for the planet with local peers at Societe makes it that much more rewarding."

Closed Loops stands as a liquid celebration of this milestone. Crafted using Tropical Fusion, Mosaic, and Strata Cryo hops, this hazy IPA pours a murky pale yellow color and delivers vibrant notes of grapefruit rind, cherry, and lemongrass, balanced by a soft mouthfeel and a smooth, clean finish.

Closed Loops is now available on draft and in 4-packs to go at all five Pure Project taprooms in San Diego County and at select retailers.
