Every summer the Salt Lake County Health Department hosts Household Hazardous Waste Collection Events throughout the county. At these events Salt Lake County residents can bring their hazardous garbage that you are not supposed to put into your regular trash cans. Things like pharmaceuticals, electronics, fuels, chemicals, and batteries. And it's free! I'll post a link to their site and the flyer with the event info below. If you can't make it to the event, you can take these items to the landfill for free anytime during the year.
