What is household hazardous waste?
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
Why can't I just throw HHW away with the trash?
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!

Drop 'N' Swap
The Drop 'N' Swap is a favorite among County residents. Through the Drop 'N' Swap, we offer usable, low-toxicity 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 pesticide 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 MONDAY, Tuesday, Thursday, Friday and Saturday 8:00 a.m. - 4:30 p.m. Do not leave any items on the ground or outside the building when the facility is closed.
The Household Hazardous Waste Collection Facility offers tours to the public. Schools, boy/girl scout troops, businesses, or anyone else who may be interested in finding out more about the operation may call (970) 498-5773 to set up a tour of the facility.
