The Environmental Protection Agency (EPA) designed the waste manifest to ensure the safe transportation and disposal of non-hazardous and hazardous waste.

All cannabis operators (cultivators, manufacturers, distributors, retailers, testing laboratories, and events) generate cannabis waste. Depending on the type of operation, operators may generate both hazardous and non-hazardous waste. These are the ‘generators’.

Cannabis waste adds another layer of complexity to waste manifesting. If the cannabis waste is not yet rendered “unusable and unrecognizable” and is being transported to a processing facility, it also requires a cannabis distribution (transport) license. This applies to both non-hazardous and hazardous waste.

For hazardous waste in general, in order to transport hazardous waste, the transporter company must be approved and licensed by the state. If you are generating hazardous waste, it’s important to ensure your transporter services are licensed and compliant. These are the ‘transporters’.

The waste manifest system tracks waste from the time it leaves the generator facility to the time it reaches an off-site waste management facility. The waste management facility can store, treat and render the waste into either non-hazardous waste (oftentimes, compost) or securely and properly dispose of the remaining hazardous matter. The final destination is the ‘designated facility’.

There are two types of manifests – non-hazardous and hazardous. Non-hazardous waste manifests are more loosely regulated. Hazardous waste manifests are more strict and are provided by the state with identification numbers. Both are required in the waste removal process, and both require documentation of name, location, date, weight, and type. They also require a signature from the generator, transporter and the designated facility.

The hazardous waste manifests have six (6) copies: one for the generator, one for the transporter and three for the waste disposal facility. Once the waste has been dropped off, the waste disposal facility sends a completed waste manifest to the waste generator and to the state. This way the generator and waste disposal facility can prove to the state they are conducting compliant waste disposal practices.

GAIACA’s cradle-to-grave full-service cannabis waste management approach ensures that all operators are compliant and also sustainable. GAIACA sends waste manifests to the state on a monthly basis to demonstrate your compliance. If your municipality requires a copy of your waste manifests, we can arrange to report to them as well.
