The Denver Beer Company in Colorado is working with the marijuana industry to launch a program to sell excess carbon dioxide to the cannabis company The Clinic in order to fertilize their marijuana crops. The exchange is part of the Carbon Dioxide Reuse Pilot Project announced by the governor of Colorado and the Department of Public Health and Environment (CDPHE). The program fixes a closed loop economic model where CO2 is normally purchased through outside sources and recovery does not normally factor into the equation. The Marijuana industry uses CO2 to stimulate plant growth and achieve higher yields.

The Denver beer Co. can capture 100,000 lbs. per year by implementing the innovation while saving money on purchasing CO2 and avoiding the emissions resulted from shipping in CO2 from outside sources altogether. If implemented throughout the alcohol and cannabis industries, massive amounts of Carbon would be saved from entering the atmosphere.

The company Earthly Labs, based in Austin, TX, developed the turn-key system to capture CO2 emitted from the brewing process. The captured gas can then be used in a variety of ways including pouring beverages on site or sold to others who use CO2 for their business but focusing on the marijuana industry and other breweries. The new program aims to reduce the impact that the two large industries have in the state of Colorado but could be used in other states where legal marijuana exists like California, Oregon, and Washington.
