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.
Your business may receive no-fee hazardous waste disposal up to four times a year if it is an eligible business.
Hazardous waste is accepted from eligible businesses at our four collection sites and travelling Wastemobile.
IMEX is a free listing service that helps your business locate useful materials or give away surplus materials and hazardous products.
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.
