Household Hazardous Waste

Household Hazardous Waste (HHW) can be dropped off free of charge at the Spokane County Regional Solid Waste Disposal sites. Materials that are considered HHW include:
  • Any products that may be labeled "danger", "warning", or "caution"
  • Automotive products (oil, antifreeze, gasoline, etc.- limit 5 gallons per visit)
  • CFL and fluorescent light bulbs (limit 10 bulbs per visit)
  • Paints (limit 15 gallons per visit)
  • Batteries
  • Cleaning products
  • Herbicides, pesticides
  •  Needles/syringes/sharps
  •  Out-of-date prescription medications
  • Solvents (limit 5 gallons per visit)
  • Thermostats or thermometers that contain mercury

The waste needs to be in containers that are five gallons or less. Use the original container with the label intact whenever possible.

Recycling and Disposal of Empty Containers


A container is empty when all contents have been removed by normal means, such as inverting and draining, shaking, scraping, or scooping. After all common methods are used, the container is considered empty when the following conditions are met: 

•Small containers (less than 119 gallons), are empty when no more than one inch or 3 percent of container volume remains.
•Large containers (greater than 119 gallons), are empty when no more than 0.3 percent of container volume remains. 

Aerosol Cans are a special kind of empty container because the contents are under pressure. Containers holding compressed gases are empty when the pressure inside the container is equal or nearly equal to atmospheric pressure. 
Once product has been removed you may rinse the container. Keep rinse water to a minimum. Containers which held acute hazardous waste or extremely toxic waste must be triple rinsed before they are disposed, reused, or recycled. Do not dump product or rinse water on the ground or down the drain. All hazardous waste mixed with rinse water must be put in a container, labeled then taken to a Hazardous Waste Area at the Transfer Stations or the Waste to Energy Facility for disposal. Once the containers are empty of the hazardous waste they can be recycled if the container material is normally accepted in single stream recycling.
