JACKSON, Wyo. — Last summer, Teton County residents kept nearly 24 tons of hazardous waste out of the landfill, waterways and ecosystem — from 11,700 mercury-containing fluorescent bulbs to nearly 1,300 gallons of flammable paint, along with hundreds of gallons of pesticides, herbicides and antifreeze. Now, it’s that time of year again. Spring cleaning means taking stock in the garage and disposing of unwanted items the right way.

Teton County’s Household Hazardous Waste collection season began April 15, with appointments available for all 2026 collection dates through October. Collection takes place twice a month by appointment only at the household hazardous waste (HHW) facility located behind the Recycling Center at 3270 S. Adams Canyon Road.

“Appointments fill early, so it helps to plan ahead,” said Cindy Harger, Waste Diversion Outreach Coordinator. 

Household Hazardous Waste (HHW)

HHW includes materials that are toxic, corrosive, ignitable or reactive, and require special disposal. The HHW facility accepts a wide range of items, including:

  • Oil-based paints
  • Solvents
  • Pesticides
  • Certain cleaning products
  • Automotive fluids like anti-freeze or dirty motor oil
  • Herbicides
  • Flammable solvents
  • Turpine
  • Mercury thermometers
  • Pools chemicals
  • Fluorescent bulbs (not LED or incandescent)
  • Aerosols
  • Others

When these substances are poured down drains, onto soil or into stormwater systems, they can make their way into creeks and groundwater, impacting fish, wildlife and the broader ecosystem, according to Teton County Integrated Solid Waste and Recycling officials. Improper disposal in the trash can also contaminate entire loads and pose serious risks to sanitation workers, including exposure to harmful chemicals, fires and explosions. 

Latex (water-based) paint is not accepted but can be dried with kitty litter and placed in the trash. The facility also cannot accept ammunition, explosives, asbestos, medical or radioactive waste, or containers larger than five gallons. 

Appointments and what to bring

Appointments are required and can be made online at TetonCountyWY.gov/HHW. Call (307) 733-7678 for specific materials questions or assistance with the scheduling app. 

Collection days for 2026 are: April 15 and 29; May 13 and 27; June 10 and 24; July 15 and 29; August 12 and 26; September 9, 16 and 23; and October 7, 16 and 21.

To prepare for the appointment:

  • Bring materials in their original containers or clearly labeled.
  • Make sure lids are tightly sealed.
  • Turn off engine at the drop-off site.
  • Remain in the vehicle — staff will assist with unloading items. 
  • No smoking or cell phone use at the facility. 

Community support makes it possible

HHW collection for Teton County residents is subsidized through generous support from the Brinson Foundation, Teton Conservation District and the Teton County Weed and Pest District. These contributions help reduce costs for residents and local businesses. 

A schedule of fees is posted on the Teton County website. For more information, call Teton County Integrated Solid Waste and Recycling at (307) 733-7678 or visit TetonCountyWY.gov/HHW.
