Household Hazardous Waste Collection Options - Facilities - King County Solid Waste Division

Household hazardous waste collection options

The Solid Waste Division (SWD) operates two facilities that accept household hazardous waste from residents, the Wastemobile and the Factoria Household Hazardous Waste Drop-Off Service. Wastes collected at these sites will be recycled or disposed of properly.

Household hazardous wastes are products that contain ingredients that are toxic, flammable, reactive or corrosive. These include paint thinner, fluorescent lights, pesticides and car batteries. If disposed of improperly, these products can be harmful to humans, wildlife and the environment. Proper disposal prevents household hazardous waste from entering the environment; damaging soil, groundwater and streams; or causing harm to people and animals.

The Wastemobile and fixed facilities are funded through a surcharge on solid waste disposal and wastewater discharge and there is no direct fee to residents. The average disposal cost is over $75 per participant, however residents utilizing the facilities are not charged a fee on site. This cost premium underscores the importance of making waste prevention our top priority.


The Wastemobile is a mobile facility that travels to communities in King County and sets up in parking lots for three days at a time. Residents can bring their household hazardous waste to the Wastemobile when it is in their community. The dates, locations and hours of the Wastemobile are listed on the Wastemobile Schedule. The Auburn Wastemobile is open Saturdays and Sundays from 10 a.m. to 5 p.m. at The Outlet Collection (formerly SuperMall) – 1101 Outlet Collection Dr. SW external link . The Wastemobile is located in the northwest corner of the mall (near the Nordstrom Rack and loading docks). Watch a short video Youtube about the Wastemobile .

Created in 1989, the Wastemobile was the first program of its kind in the nation. In 25 years of operation, the program has collected nearly 15,000 tons of household hazardous waste from nearly 500,000 customers. In 21 collection events last year, the Wastemobile served more than 13,000 King County residents, collecting an average of 75 pounds of hazardous waste per customer (for a total of 506 tons).
