  • Unused cannabis trimmings.
  • Unused cannabis.
  • Unused oils, extracts, other cannabis liquids.

Who Generates Cannabis Waste?

Primarily the cannabis waste regulation was initiated to reduce the amount of waste cultivators generate. For every 128.6 sq ft (of a cultivation site) approximately 8.4 lbs of waste is generated. In order to make sure that the soil, sponge, pebbles used to grow marijuana aren’t being dumped in a public trash receptacle the cannabis waste regulation was put in place.

Lawmakers also had a growing concern that when dumping any material(s) whether it’s packaging or leftover trimmings can be scraped and smoked. This concern led to requiring dispensaries and any cannabis related business to also properly manage and dispose of their waste.
