Come visit a Hazardous Waste disposal facility

Don’t stew over your hazardous waste. Bring it to one of our disposal facilities.  

You’ve likely heard that the Hazardous Waste Management Program in King County has four hazardous waste collection sites, each offering free disposal services for residents and small businesses in King County. But have you ever wondered what the actual process is like to drop off your hazardous waste? 

Read on to learn more about the drop off process and check out the series of videos we’ve put together that walk through the visit from start to finish.  

How does it work? 

First, gather your hazardous waste, including items like batteries, cleaning supplies, and herbicides/pesticides. A full list of accepted products and quantities is available on the Haz Waste Program’s website. Next, safely secure your items in your vehicle – away from the passenger compartment. 

You can take your items to one of the following disposal locations:

Home collection for eligible King County residents 

For King County residents who are 65 years or older or who have a disability, you may qualify for the home collection program. 

To schedule a home pick-up with the Haz Waste Program, call the Haz Waste Help Line at (206) 296-4692 (Open Monday – Saturday 9 a.m. - 5 p.m. except holidays).  

All you have to do is provide your name, address, telephone number, and specify the types and amounts of waste you have for collection.
