Firestone Walker unveils advanced CO2 recovery system

By Paso Robles Press · Tue Nov 04 2025

PASO ROBLES — Firestone Walker Brewery has launched a state-of-the-art carbon dioxide (CO2) recovery system as part of its ongoing “Brewing for Tomorrow” sustainability initiative, capturing four million pounds of CO2 emissions annually. The system recycles CO2 generated during fermentation, purifying it for reuse in tank purging, packaging, and beer carbonation instead of releasing it into the atmosphere.

Constructed at a dedicated $1 million facility, the $1.8 million system was built by Pentair, a global leader in beverage production technology.

“We are always looking for new ways to brew great beer while taking care of the world around us,” said Nick Firestone. “The new CO2 recovery system is the next step in that journey, and it’s another way for us to cut emissions, conserve our resources, and make a difference for our environment and community.”

The system is part of Firestone Walker’s broader sustainability efforts, which include on-site solar arrays covering 60% of energy needs, recycling 20 million pounds of spent grains to local livestock annually, treating 40 million gallons of water for reuse, and repurposing or recycling equipment, cardboard, glass, and aluminum.

The brewery has set ambitious goals of achieving 50% carbon neutrality by 2030 and 100% carbon neutrality by 2050, addressing emissions across all operations including suppliers and transportation.

“Sustainability is built into how we run the brewery,” said Brewmaster Matt Brynildson. “Every little thing adds up. Carbon neutrality is a big target, but we’re making progress one system at a time.
