Many businesses in Washington must arrange for organic materials collection, as required by the 2022 and 2024 organics management laws expanding organics management and collection in the state.
By July 1 each year we are required under RCW 70A.205.545 to determine and post on our website areas in Washington where businesses must arrange organics management services to reduce their organic material waste. These Business Organics Management Area or BOMA determinations are valid for the following calendar year beginning January 1.
This map identifies the expanded organics collection areas that are in effect for the 2026 calendar year. Areas in blue indicate the active collection areas.
A BOMA represents those parts of the state where we have determined both qualifying conditions exist:
Businesses have access to year-round curbside food waste and organic materials collection, and these materials are delivered to an organics management facility such as a compost facility or anaerobic digester for processing
Capacity exists at these facilities to accept increased volumes of organic materials from businesses
To make this determination, we consulted with local governments, haulers, and compost facilities. We also solicited public comment on a preliminary draft of the BOMA map through our E-comments portal. The map reflects what we learned through this process.

Requesting exclusion for jurisdictions
To request an exclusion from a Business Organics Management Area, a jurisdiction must submit their request in writing to us at organics@ecy.wa.gov. Please refer to the Exclusion Request Focus Sheet for instructions.
If you are a business with questions about whether you are exempt from this law, please refer to the FAQ section below.
Organics collection requirements timeline for businesses
Only businesses located in a BOMA and dispose of a certain volume of organic materials will be impacted. You can see if a particular business is in a BOMA by using the address search bar in the top left corner of the BOMA map.
Businesses are required to comply with the following timeline:
Jan. 1, 2024 – Businesses generating at least eight cubic yards of organic material waste per week must arrange for organic materials management service.
Jan. 1, 2025 – Businesses generating at least four cubic yards of organic material waste per week must arrange for organic materials management service.
Jan. 1, 2026 – Businesses generating at least 96 gallons of organic material waste per week must arrange for organic materials management service.
These requirements also apply to businesses arranging for gardening and landscape work. Following the schedule above, they must ensure that an organics management facility will process the organic materials taken off site.
Frequently asked questions for businesses
The timeline for businesses to comply with organics collection requirements has changed. In 2026, business collection requirements have changed from four cubic yards of solid waste to 96 gallons of organic material waste. This means that the requirements will only apply to the organic materials generated by the business, not solid waste.
The business must adjust collection services to account for seasonal variability. If they exceed the minimum amounts in any period, then the businesses must subscribe to the appropriate service levels.
The term “business” in the 2022 Organics Management Law is defined as a for-profit (private or public) or nonprofit entity including, but not limited to, a partnership or corporation that is organized as a for-profit or nonprofit entity.
Businesses include restaurants, hotels, retail stores, grocery stores, food processors, distribution centers, event stadiums, museums, recreational facilities, correctional facilities, government buildings, and assisted living facilities. This definition also includes nonprofit organizations, such as schools, animal shelters, places of worship, and hospitals.
“Business,” under this definition does not include multifamily residential buildings, such as apartments, condominiums, and townhomes.
Organic materials are defined as "any solid waste that is a biological substance of plant or animal origin capable of microbial degradation.” This includes manure, yard debris, food waste, food processing waste, wood waste, and garden waste.
More specifically, food waste includes waste from fruits, vegetables, meats, dairy products, fish, shellfish, nuts, seeds, grains, and similar materials that result from the storage, preparation, cooking, handling, selling, or serving of food for human consumption.
To be in compliance, a business cannot dispose of organic material above the required threshold.
Your business must arrange for collection if, in January 2024, it generates eight cubic yards of organic material. In January 2025 businesses that generate four cubic yards of organic material must arrange for collection. By January 2026, businesses that generate four cubic yards of solid waste must arrange for organics collection.
Businesses may also be exempt from organics collection requirements in the following conditions:
Organic materials are managed onsite.
Organic materials from growing food or fiber are used offsite by a business for growing food or fiber.
Organic materials are sold or donated to another business for offsite use.
Organic materials are generated from a natural disaster.
Organic materials are self-hauled to an organic materials management facility.
Businesses are primarily responsible for determining if the requirements apply to them. To do this they will need help from their haulers, local governments, and others to learn about the law, if it applies to them, and how to comply.
We will provide resources to help identify what businesses may be impacted by the law and options to comply.
In 2024, only a small subset of all businesses will be impacted. As they are identified, technical assistance can be initially focused on helping them. This will include providing information on options other than organics collection to meet the requirements in the law. These other options include implementing food waste prevention systems and participating in food rescue programs.
Jurisdictional health departments may enforce the requirement that businesses must arrange for organics materials management services if they are located in the BOMA map,
The jurisdiction must issue two written notices prior to issuing penalties, and they must not charge businesses a fee associated with the administration and enforcement of these requirements.
