With growing concerns at GAIACA regarding environmental and public safety, we have decided to take some drastic actions. This month we have installed a 150,000-gallon pond, lined with heavy-duty polyvinyl chloride (PVC) to control potential harsh liquid runoff and protect the environment.
The purpose of the compost liner and retention pond is to capture any potential contaminants that may leech from commercial cannabis composting. Little to no research has been done on the impact that cannabis constituents (THC, CBD, CBN, etc.) may have on our environment and public health. In addition to this, harsher contaminants from cultivation and manufacturing practices (pesticides, fertilizers, and solvents) may reside within the composted cannabis.
Although compost containment is not yet required by law, and the environmental impacts may be negligible or even non-existent, we at GAIACA hold ourselves to the highest standard when it comes to safety and protection of the environment.
If you are interested in the specifics, the pond liner is a 1/2-acre plot that is permitted for commercial composting activity, contained with a low-permeability, synthetic geomembrane liner to control fluid migration. The liner is 30 millimeters in thickness, constructed out of polyvinyl chloride (PVC) and is set approximately 4 feet in depth, below a French drain. Any water flow (i.e. rain, intentional wetting, leachate, etc.) will be captured by the liner and funnel into a drain on the lowest end. A retention pond stands adjacent to the compost area, to accept any diverted water flow. The pond is also lined with similar geomembrane liner, however, it is 36 millimeters in thickness, constructed out of polypropylene, designed to sustain UV exposure. The pond is approximately 150,000 gallons, built to withstand a minimum 10-year storm.
The environment comes first for us, and we want to make sure that our current actions, though they have good intentions, will not affect future generations to come. All our commercial cannabis composting activity is conducted in a controlled environment where water runoff can be captured and tested for treatment, therefore mitigating any potential harm to the environment and public health.
