03 Apr Safely dispose of oil-based paints, pesticides and more: HHW Collection Season begins
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 time to clean out the garage again. Teton County’s Household Hazardous Waste collection season begins Wednesday, April 15, with appointments available for all 2026 collection dates through October. Collection takes place twice a month by appointment only at the HHW facility located behind the Recycling Center at 3270 S. Adams Canyon Road.
Household Hazardous Waste includes materials that are toxic, corrosive, ignitable or reactive — such as oil-based paints, solvents, pesticides and certain cleaning products — and require special disposal.
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. That’s where the HHW program comes in.
What You Can Bring
The HHW facility accepts a wide range of items, including:
- Oil-based paints, stains and turpentine,
- Automotive fluids like anti-freeze and dirty motor oil,
- Pesticides and herbicides,
- Flammable solvents and turpentine,
- Mercury thermometers, pool chemicals and toxic cleaning products,
- Fluorescent bulbs (not LED or incandescent), aerosols and more.
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.

Community Support Makes It Possible
