The Liquor and Cannabis Board (LCB) licenses cannabis businesses in Washington and regulates activities related to cannabis. A licensed cannabis producer may produce, harvest, trim, dry, cure, and package cannabis into lots for sale at wholesale to cannabis processor licensees and to other cannabis producer licensees. A licensed cannabis processor may process, dry, cure, package, and label usable cannabis, cannabis concentrates, and cannabis-infused products for sale at wholesale to retailers and other cannabis processors.
Cannabis Waste Disposal.
The LCB rules require solid wastes, liquid wastes, and wastewater generated during cannabis production and processing to be stored, managed, and disposed of in compliance with the LCB rules and applicable state and local laws and regulations. Methods of disposal are different based on the type of waste and whether the waste is designated as dangerous and must be disposed of pursuant to the Hazardous Waste Management Act (HWMA). The waste generator is responsible for evaluating their waste to determine if it is designated dangerous waste. Waste that must be evaluated against dangerous waste regulations include:
Cannabis waste that is not designated as dangerous waste must be rendered unusable prior to disposal by grinding and incorporating the waste with other specified ground materials so the resulting mixture is at least 50 percent noncannabis waste by volume. The LCB may approve other methods to render cannabis waste unusable. After the waste is rendered unusable, it must be properly disposed of at a permitted facility with approval of the jurisdictional health department, and a record must be kept of the final destination of the cannabis waste.
Hazardous Waste Management Act.
The HWMA requires dangerous waste generators to properly dispose of waste at approved dangerous waste management sites and facilities. Persons who generate dangerous waste are responsible for identifying their wastes as such, based on characteristics including the waste's corrosiveness, ignitability, toxicity, and reactivity. Dangerous wastes is defined as any discarded, useless, unwanted, or abandoned substances, including, but not limited to certain pesticides, or any residues or containers of such substances which are disposed of in such quantity or concentration as to pose a substantial present or potential hazard to human health, wildlife, or the environment. Hazardous waste is defined as all dangerous and extremely hazardous waste, including substances composed of both radioactive and hazardous components.
Cannabis Waste Disposal.
Cannabis waste is defined as solid waste that is generated during cannabis production or processing that has a tetrahydrocannabinol (THC) concentration of 0.3 percent or less and does not apply to hemp or industrial hemp.
A licensed cannabis producer and a licensed cannabis processor may sell cannabis waste to a person not licensed by the LCB if:
Cannabis waste not sold by a licensed producer or processor must be rendered unusable before leaving a licensed producer, processor, or laboratory.
The amended bill requires licensed cannabis producers and processors to comply with the following additional requirements to sell any cannabis waste. Licensed cannabis producers and processors must:
The amended bill also clarifies that nothing prohibits licensed cannabis producers and processors from selling cannabis waste to a person who is not licensed by the LCB if certain requirements for the transfer are satisfied.
(In support) It is in the best interest of cannabis producers and processors to extract out every bit of cannabinoids in cannabis waste, so the industry would not want to leave any cannabinoids in the waste. The industry is not going to be disposing of valuable cannabinoid products and an amendment to clarify that the product cannot be used to make THC products would be fine. Licensees should not be selling any cannabis below acquisition cost, but they currently must pay to dispose of this cannabis waste. It would be helpful to be able to give away cannabis waste rather than just being authorized to sell it. The Legislature passed a bill to divert 75 percent of organic material from landfills because it creates methane gas. According to wholesale revenues, cannabis is the fourth highest revenue crop in Washington, so there are a lot of farms that could benefit from this bill. Each producer generates between 500 to 1,000 pounds of green waste a week during harvest season. Currently, cannabis waste must be ground and then combined with kitty litter which just adds more waste to landfills. Changes should be made to get rid of this waste as easily as possible and get it to someone who may want to recycle it into hempcrete, hemp fiber, compost, or for other purposes. There is unanimous industry support of this legislation along with support from Zero Waste Washington. The plant material has been tested during harvesting and it always stays well below the 0.3 percent THC threshold. This material can be used for anything that hemp is used for in sustainable building materials.
(Opposed) None.
