Hazardous Waste Program’s 2025 Wastemobile Season Recap

Wastemobile staff sorting items from customer drop off

As we get ready to kick-off the upcoming Wastemobile season in a couple weeks, we want to take one final look back at how successful the past year was. More than 10,000 residents across King County used the Hazardous Waste Program’s Wastemobile to safely and conveniently dispose of their hazardous waste in 2025.

Last year’s attendance was slightly lower than 2024 when 11,407 customers visited the Wastemobile. However, we saw more people use the Program’s permanent collection sites than in 2024.

The Wastemobile gives residents and businesses a safe and easy way to dispose of hazardous products from their homes and workplaces by hosting events in communities across the county each year. These events are designed to supplement the three collection sites in South Seattle, North Seattle and Factoria.

Year in Review

During the 2025 season, the Wastemobile:

  • Visited 12 cities
  • Hosted 21 events
  • Served 10,048 customers
  • Collected 502,874 pounds of hazardous waste

The Wastemobile made stops in Bothell/Woodinville, Kent/Covington, Redmond, Vashon Island, Kirkland, Enumclaw, Snoqualmie, Des Moines, Sammamish, Carnation/Duvall, Burien, and Renton, helping ensure people across King County had access to safe disposal options.

What We Collected

The Wastemobile collects many types of hazardous materials from residents and businesses. The most common or highest-volume items included:

  • Oil-based paint
  • Automotive oil
  • Flammable liquids
  • Liquid pesticides
  • Batteries
  • Bases
  • Antifreeze

Looking Ahead to 2026

Beyond continuing to improve access to disposal services, we are working to raise awareness about the risks of keeping hazardous products in homes and garages.

While the 2026 Wastemobile season is still a couple weeks away, safe disposal options are available year-round. Many common household hazardous items, including oil-based paint, batteries, stains, household cleaners and pesticides are accepted at our permanent collection sites. Visit our product library to learn more.

We’re looking forward to coming to a community near you for another season of helping King County residents safely dispose of hazardous waste.
