We help eligible King County businesses access resources to safely dispose of hazardous waste. Find a convenient disposal location, visit the traveling Wastemobile, or list surplus items on the Industrial Materials Exchange (IMEX). These disposal services are provided at no additional fee.
Visit our product list for businesses to find out what types of hazardous waste we accept. If your business exceeds the noted limits, it may require disposal service via a private hazardous waste management firm. We can help! For questions or more information, call 206-296-4692.
Your business may receive no-fee hazardous waste disposal up to four times a year if it is an eligible business.
This program is for King County businesses that generate less than 220 lbs of hazardous waste monthly and less than 2.2 lbs of certain Extremely Hazardous Wastes, and are Conditionally Exempt Small Quantity of Generators under Washington State Department of Ecology Dangerous Waste Regulations (WAC 173-303).
If the label includes the words danger, poison, warning, or caution, it's hazardous waste.
