Commercial organics diversion

Learn about your business or commercial property’s options for diverting food and yard waste.

King County businesses can save money and reduce waste by diverting food and yard waste from the landfill. Organics collection is often less costly than garbage disposal. Materials can be donated or turned into earth-friendly compost at a local facility.

What are organic materials? What can be composted in my area?

Materials Compostable?
Food scraps, such as produce, dairy, grains, meat, bones, and eggshells


Food-soiled paper and boxes that do not have a waxy/shiny coating


Plants, flowers, yard waste, and untreated wood


NO pet waste or diapers


NO fats, oil, or grease


Help create nutrient-rich compost by checking what goes in the organics bin and what stays out. Compost is used on our local landscapes to maintain a healthy environment for plants, animals, and people. See more at Compost Right.

2022 Organics Management Law (OML)

Beginning in 2024, certain businesses throughout the state of Washington will be required to divert organic waste from the garbage by donating edible food, establishing curbside collection, self-hauling to a transfer station that accepts the waste, and/or composting on site.

  • January 1, 2024 - Businesses generating at least eight cubic yards of organic waste per week must arrange for organic materials management.
  • January 1, 2025 – Businesses generating at least four cubic yards of organic waste per week must arrange for organic materials management.
  • January 1, 2026 – Businesses generating at least 96 gallons of organic waste per week must arrange for organic materials management

How do I know if my business is required to comply with the law?

Conducting a “waste audit” is a great way to start. Evaluate how often your outdoor garbage containers fill up and about how much is food/yard waste. Estimates are OK! Determine what size your containers are and how often they are serviced by a hauler. If you are near the law’s threshold for the year, reach out to a waste hauler or explore ways to reduce your organic waste.

Only businesses in geographic areas designated by the Department of Ecology will be required to comply. These areas will be updated every year in July. As of 2024, the majority of western King County is included. To verify if your business address is included, please visit Ecology’s interactive map: 2024 Business Organics Management Areas (BOMA).

Establish curbside collection

Some cities may already hold a contract that covers organic waste collection for your business. Check with your city’s recycling coordinator or solid waste lead. For businesses not covered by a city contract, there are a variety of organic waste haulers in King County you may choose to work with, such as:

  • Cedar Grove
  • Commercial Waste Reduction and Recycling (CWRR)
  • Recology
  • Republic Services
  • Waste Management

For temporary container service, many other providers are available. Visit the What do I do with…? site and search for food or yard waste.
