The US state of Colorado has announced the successful conclusion of a pilot program to use waste carbon dioxide (CO2) from beer brewing to grow cannabis.
The Denver Beer Company captured CO2 during the fermentation process, then supplied it to cannabis grower The Clinic to stimulate plant growth.
The pilot revealed the Denver Beer Company was able to keep the equivalent of around 93 trees’ worth of CO2 from the atmosphere, while fulfilling The Clinics’ CO2 needs for a 16-week harvest, 15 per cent cheaper than commercial CO2.
The plants met all their key growth milestones and The Clinic’s natural, CO2-powered cannabis product “93 Hoppy Trees” is now available in bud form online. The companies plans to expand the partnership and offer the product year-round.
