Typical household hazardous waste is accepted from Larimer County Residents at no charge.  All other waste is subject to approval through the business program.

Household hazardous waste (HHW) is any substance containing ingredients that could negatively affect your safety, health or the environment. Signal words found on hazardous products include poison, danger, warning and caution. They can be found on a wide range of products, including furniture polish, bleach, antifreeze, insecticides, paint, mothballs and much more.

Also look for indications of hazardous properties on the label. Such properties are defined by the Environmental Hazards Management Institute as follows:

  • 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
  • Explosive: violently bursting when exposed to pressure or heat
  • Irritant: causes soreness or swelling of the skin, eyes, mucous membranes or respiratory system

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.

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!

How to prepare for your visit:

  • Our limit is 30 gallons of waste at a time, based on container size, and 10 fluorescent bulbs per load
  • Package your household chemicals in non-leaking, labeled containers. Keep chemicals in their original containers when possible.  It's best to drop off items in containers that can be left at the facility.
  • Pack your waste upright in boxes. Do not bring waste in garbage bags or large containers such as trash cans. Waste packaged this way is at risk for leaking and mixing, posing a hazard to you and to HHW Staff.
  • Review our list of accepted materials and sort out what we will not accept.
    • Containers must be 5 gallons or smaller.
    • Remove ballasts and fluorescent bulbs from fixtures. How to remove a ballast from a fluorescent fixture.
    • Make sure sharps are in acceptable containers.
    • Remove trash like incandescent light bulbs, empty and dry paint cans, and soiled paint brushes from your load.

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.

The Drop 'N' Swap is a favorite among County residents. Through the Drop 'N' Swap, we offer usable products under our "Buy none, get one free" policy.

Here's how it works: Say you need about half a gallon of latex paint, a little bit of copper cleaner, just enough herbicide to kill a pesky patch of weeds, and camp stove fuel to get through the weekend. Chances are we have all these items and more. Just stop by the Hazardous Waste Facility, pick up what you want, and let us thank you on the way out.

About 30,000 pounds of hazardous household products are reused through the Drop 'N' Swap program each year, keeping them out of the landfill and out of groundwater. The best way to dispose of chemicals is to use them up as they were originally intended to be used, which is just what this program does. And, of course, it's free!

The Drop 'N' Swap is open Tuesday and Thursday from 9 am - 3:20 pm by appointment only. Read the new shopping procedures and make an appointment. Do not leave any items on the ground or outside the building when the facility is closed.
