Cannabis Waste

Compost (Yard Trimmings) Cart Facility Drop-Off

Cannabis businesses can drop off cannabis waste at the Napa Recycling & Composting Facility (fee is the same as that for yard trimmings) – you will receive a cannabis waste weight tag for your chain of custody requirements.  Please remove non-compostable packaging and use compostable materials (yard trimmings, leaves, shredded paper, sawdust, etc.) when rendering it “unusable” for transportation. 

Vape pen batteries can cause dangerous fires when not disposed of properly – they must be recycled separately and never disposed of in the trash, recycling or compost.

Only Cannabis Plant Parts Belong in the Compost

Leaves, flowers, and other parts from a cannabis plant can be composted as long as they do not contain or are combined with any hazardous or toxic materials. Cannabis wrapped in a cigar wrapper, cigarette rolling paper, or any other toxic materials must be disposed of in the landfill.
