Flowr, a cannabis production company located outside of Toronto, recently reached out to Green Mountain Technologies (GMT) to find an affordable option for processing their cannabis waste, and one that complies with regulations. They also were on a tight timeline.

U.S. and Canadian cannabis growing operations face stringent regulations for disposal of cannabis plant waste, including the requirement to shred plant waste and mix it with an inert substance like cat litter, sand, plastic waste, or sawdust until it's deemed "unrecognizable and irrecoverable."  

According to Green Mountain Technologies (GMT) this adds extra labour costs, doubles disposal costs and is not environmentally sustainable. 

The GMT solution for efficiently managing cannabis waste at Flowr 's operations is a 32-foot refurbished custom steel vessel called Earth Flow. The composter includes a computer-controlled auger and a continuous flow design, allowing growers to add new material every day and harvest finished product every seven days. The entire process from unloading to discharging the final product takes between 14-21 days. 

According to GMT, this is a highly efficient model for composting compared to other methods and allows customers to use the fertile compost created by the process as a soil amendment right away. 

Since their installation of the GMT Earth Flow system, Flowr says they cut down on costs and manufacturing time significantly, and they now have access to a nutrient-rich, pathogen-free soil that is available as a substrate for continued growing operations. Plus, they have eliminated the need to buy new soils and fertilizers. Flowr estimates that they will pay off their investment in less than a year.
