FREE Household Hazardous Waste (HHW) Collection Events

Stack of hazardous waste products

What is HHW?

Household hazardous waste (HHW) is any substance containing ingredients that could negatively affect your safety, health (or that of a pet/animal) or the environment when disposed of incorrectly.

HHWs are found in everyday products and can be poisonous, corrosive, flammable, explosive or reactive. Signal words on packaging may include poison, toxic, danger, warning and/or caution.

Disposing of HHW can be tricky and these free events help take out the guesswork.

Most HHWs Are Accepted:

  • household batteries
  • pesticides and fertilizers
  • cleaners and bleaches
  • fluorescent light bulbs
  • pool and hot tub chemicals
  • vitamins and supplements
  • painting products (stain, solvent, spray paint)
  • automotive products (virtually all fluids)
  • personal care products (shampoo, lotion, nail polish remover)
  • mercury-containing items (thermostats, button-shaped batteries)

Year-Round HHW Disposal Opportunities

Did you know about 50% of the items collected at our bi-annual HHW events can be disposed of at the City's TRC Hard-to-Recycle Yard? The TRC accepts antifreeze, household batteries, motor/cooking oil and paint, free of charge year-round.

Visit for local disposal options for non-accepted items and other non-HHW household items.

Also, Larimer County’s Household Hazardous Waste Facility accepts most HHWs year-round.

Handle With Care

The risk of fire, explosion and spills exists when transporting HHW. Please prepare items safely for transport, following these rules:

  • store items upright in boxes or tubs, not loose bags
  • keep similar items together (do not stack)
  • seal containers tightly and ensure they are not leaking
  • separate acids and oxidizers 
  • keep items away from children and pets

Prescription Drug Take-Back Programs Help Protect Our Community and Waterways

Do NOT flush your old or leftover prescription drugs or other pharmaceuticals/medications down the drain. Wastewater treatment plants are not designed to remove these chemicals and compounds, and they can pass through to local waterways and have harmful effects on animals, humans and the environment.

Safe disposal practices for unused prescription and over-the-counter medications are important to keep pharmaceuticals out of water bodies. 

Fort Collins Police Services offers a free and anonymous Daily Prescription Drug Take-Back Program. Items not accepted include intravenous solutions, injectables, syringes, mercury (thermometers), oxygen containers, chemotherapy/radioactive substances, pressurized canisters and illicit drugs. Learn more.
