Closed to the public Wednesday

Free for Larimer County residents:

Typical household hazardous waste is accepted from Larimer County Residents for free.  All other waste, including waste from businesses, churches, landlords, local governments, non-profits, and other organizations is subject to approval through the business program.

We accept:

  • Paint
  • Lawn Chemicals
  • Automotive Fluids
  • Batteries
  • Cleaners 
  • And more -- check out the Accepted Items list below.

Know before you go:

  • The limit is 30 gallons per visit, measured by the size of the container (not how full it is), or about 4 medium-sized moving boxes.
  • Containers larger than 5 gallon capacity will not be accepted.
  • We will take up to 10 fluorescent bulbs per visit.
  • Bring your household chemicals in non-leaking, labeled containers. Keep chemicals in their original containers when possible.  
  • Please package waste upright in boxes to prevent spilling and mixing. Don't use trash bags or throw things in trash cans.
  • Remove trash like incandescent light bulbs, empty and dry paint cans, and soiled paint brushes from your load.
  • From out of county? We can only accept waste from Larimer County Residents. Find your county's HHW:

The HHW staff and manager reserve the right to refuse waste that is unacceptable, unsafe, or not a typical residential waste. If you have commercial waste, or other waste that's not from your personal use, please see the business waste section.

Drop N' Swap

Household hazardous waste (HHW) is any substance containing ingredients that could negatively affect your safety, health or the environment. Many products may be hazardous, including furniture polish, bleach, antifreeze, insecticides, paint, mothballs and much more.

How to identify Hazardous Waste:

Look for signal words on product packaging, including:

  • poison,
  • danger,
  • warning and 
  • caution. 

You can also look for indications of hazardous properties on the label. The Environmental Hazards Management Institute defines the following hazardous properties;

  • Toxic: can cause injury or death if swallowed, absorbed or inhaled
  • Flammable: easily catches fire and tends to burn rapidly
  • Corrosive: a chemical or its vapors that can cause a material or living tissue to be destroyed
  • Irritant: causes soreness or swelling of the skin, eyes, mucous membranes or respiratory system
  • Explosive: violently bursting when exposed to pressure or heat

Dumping unused portions of household hazardous wastes in the trash or down the drain can cause safety and environmental problems. If buried in the landfill, chemicals can react and cause explosions or make their way into the groundwater. While the county strictly monitors the landfill's groundwater and gas emissions, and acts quickly to rectify any problems found, it is much easier to prevent such problems from occurring in the first place by properly disposing of or recycling hazardous wastes.

Properly disposing of hazardous waste through the hazardous waste program also helps protect our County's lakes, streams, and ponds.

So please act responsibly! Bring your unwanted HHW to the county's hazardous waste collection facility at the landfill. It's free for all Larimer County residents.

Fluorescent Bulbs and Ballasts

  • We accept up to 10 florescent tubes per visit.
  • Please bundle bulbs without tape (use twine, rubber bands, or wire ties) or bring them in boxes. 
  • Handle bulbs with care. They contain mercury vapor that is released when they break. 
Ballast (Pictured): 
  • The ballast is inside of the fluorescent fixture and needs to be removed for proper disposal.
  • Ballasts make fluorescent lamps start and regulate the flow of electricity through bulbs.
  • Some ballasts contain hazardous substances, like PCBs or polychlorinated biphenyls. PCBs have been shown to cause cancer and other adverse health effects. 
  • Bring your ballasts to the HHW for recycling!
Fluorescent Fixtures:

We will not accept the entire fixture, just the bulbs and ballasts. Please disassemble them before you come. 

sharps container


  • Sharps are accepted from Larimer County Residents ONLY
