Household hazardous waste (HHW) includes household items that usually carry words like caution, warning, danger, corrosive, poison, flammable, combustible, and explosive. HHW can be dropped off free of charge at the Spokane County Regional Solid Waste Disposal sites. Household Hazardous Waste is accepted on Saturday and Sunday only at the Spokane County Transfer Stations. The City of Spokane's Waste to Energy (WTE) Facility provides 7-day HHW drop-off; visit the City of Spokane's HHW Page for more information. Please view the Solid Waste Department HHW Guide for a more detailed list of acceptable HHW items at the Spokane County Transfer Stations. Need to know where to take a specific HHW item?
