search menu Household Hazardous Waste Household Hazardous Waste (HHW): Any unwanted household product labeled as flammable, toxic, corrosive, or reactive. Before you throw that chemical away, is there a better place for it than in your trash can or down the drain? Many common household chemicals can cause damage to the environment when they are not disposed of properly. We don't want hazardous waste in our landfills either. These are some of the items that require special "pitching" instructions. Some can be disposed of at local landfill while others can be recycled or disposed of through other local sources or at a Household Hazardous Waste (HHW) Event. The next Household Hazardous Waste (HHW) event in Pennington County is on Saturday, October 16, 2021.
