News It’s a Match – Breweries and Cannabis Growers Share CO2

It’s a perfect marriage of sorts. Commercial cannabis growers using the CO2 that brewers emit naturally during fermentation and normally vent into the air, adding a greenhouse gas to the atmosphere..

The State of Colorado and three Colorado business, Earthly Labs, Denver Beer Co., and The Clinic have started a pilot program to establish the first commercial exchange of recovered carbon dioxide. The pilot program captures and stores excess carbon dioxide produced during the beer fermentation process for later reuse by cannabis cultivators that require carbon dioxide to stimulate plant growth during cultivation.

Denver Beer Co., Colorado’s seventh-largest craft brewery by volume, is testing technology to capture carbon dioxide into a refrigerator-sized device which purifies and chills it into a liquid. The recovered CO2 is taken to an indoor cannabis grow where it is released to speed photosynthesis.

Sounds like a good collaboration beer idea!

    I’m amazed, I have to admit. Seldom do I encounter a blog that’s both equally educative and entertaining, and let me tell you, you’ve hit the nail on the head.

    The problem is something not enough people are speaking
    intelligently about. I am very happy that I came across this during my hunt for something relating to this.

    Hi, I’m interested in the chilling system. Do you have any information about it? If it is fridge-sized, I’d be interested in incorporating one into my next brewery project. I am quite in love with the idea of small scale CO2 recovery. Cheers.

    Buddies of mine grew their own in college in a dorm room! The repurposed a couple co2 fire extinguishers by adding dry ice to water inside the extinguishers then waited for the pressure to build then would release it into the room with their plants and wow. They produced some good shit for the 70s.
