Household Hazardous Waste

FREE service for all Walla Walla County residents!

The Household Hazardous Waste Facility provides citizens of Walla Walla County a way to properly manage their household hazardous waste. Examples of household hazardous waste include: paint, pesticides, and motor oil. If you have a question about what the HHW Facility will accept, please refer to the specific lists below or give us a call.

This waste, if improperly disposed of - such as thrown in the trash, poured in storm drains, sewers, or on the ground -could contaminate streams or creeks, expose children and pets to dangerous materials or poisons, and harm the environment.



Poison Prevention Week is March 20 - 26

 Poison Prevention Week focuses on educating the public about the potential for accidental poisoning from chemicals that are commonly found in homes. More than 2 million poisonings are reported to poison centers in the United States each year with more than half of the reported cases being children under 6 years old. More information on Poison Prevention Week can be found at


LightRecycle Offers Free Disposal of Mercury Containing Lights

A new program designed to collect and properly dispose and recycle mercury containing lights went into effect on January 1, 2015. The Sudbury HHW facility is participating in this program as well as Batteries+Bulbs. Please see the LightRecycle website for program details.


E-Cycle Washington Offers Free Disposal of Select Electronics

Do you have old electronic devices that you'd like to recycle? Remember that Washington State offers free recycling of old televisions, computers, monitors, laptops, e-readers, and portable DVD players. Check the E-Cycle Washington webpage for free recycling locations in Walla Walla County. (Please note: the Sudbury Landfill HHW Facility does not participate in E-Cycle and charges for disposal of electronics).

Christmas is right around the corner and with gifts come lots of batteries. What should you do with all those batteries when they are dead? The HHW facility will accept batteries from households free of charge. So when those toys and gadgets need new batteries, remember to properly dispose of your batteries by bringing them to the HHW facility. When certain types of batteries are disposed of in the garbage they can potentially cause a fire in a garbage truck or in the landfill when they are crushed.

Contact the manufacturer of your smoke detector for additional information on the safe disposal of this product. Asbestos must be properly bagged as a hazardous material before disposal at Sudbury Landfill.

Proper disposal of medications is also important, but not offered at the HHW facility. Please contact your local law enforcement agency to inquire about sponsored take-back events. Never flush unused medications down the drain or toilet as it can impact the ability of the Wastewater Treatment Plant to properly treat sewage. Here are some more tips on how to properly dispose of medications.

Less Toxic Alternatives

Proper management of household hazardous waste begins by eliminating many of those toxic products to begin with. Looking for safer cleaning products for your home? Here are some great recipes for creating your own cleaning products that are safer and cheaper.


Non-Residential Moderate Risk Waste Disposal
