About Wyoming programs
Wyoming has no statewide household hazardous waste collection; cities, counties and solid waste districts run their own. Cheyenne, Casper, Gillette, Laramie, Sheridan and Rock Springs take household hazardous waste year-round, some by appointment. Teton and Fremont counties collect only during part of the year, and many counties have no program.
Many Wyoming counties have no household hazardous waste program, and some collect only on a few days a year. Where we list no current program, call your county landfill or solid waste office about local options.
State rules and programs
- Local programs: Wyoming has no state household hazardous waste program; each city, county or solid waste district decides what it takes and when.
- Residents only: most Wyoming programs serve only residents of the city or county that runs them, and several are free for residents. Business waste is usually not accepted or carries a fee.
- Appointments: Laramie (Albany County) and Sheridan take household hazardous waste by appointment only; call ahead.
- Paint: Wyoming has no PaintCare program, so stores are not required to take leftover paint. Several sites we list take oil-based paint; Cheyenne, Gillette and Laramie say to dry out latex paint and put it in the trash. See the paint guide.
- Car batteries: Wyoming law bans throwing lead-acid batteries in the trash and requires stores that sell them to take used ones back.
Batteries in Wyoming
The law: Wyoming law says no one may put a used lead-acid battery in mixed household trash or dispose of it except by delivering it to a battery retailer or wholesaler, an authorized collection or recycling facility, or an EPA-permitted secondary lead smelter. A store that sells lead-acid batteries must accept used ones from customers, at least as many as the new batteries it sells each year, and must post a notice saying so.
Stewardship program: Wyoming has no battery stewardship program for household batteries. Some household hazardous waste sites take rechargeable or car batteries; Casper’s landfill recycles rechargeable batteries free. Check each listing for the kinds it accepts.
Where to take them: 3 Wyoming programs we list accept batteries. Some take only certain kinds, so check each listing. Programs that list batteries include Casper Regional Solid Waste Facility Household Hazardous Waste, Campbell County Landfill Household Hazardous Waste and City of Laramie Landfill Household Hazardous Waste. Pick your county above for every program.
