Household Hazardous Waste

Many of the products we use every day in our homes can be hazardous to people and the environment if they are used or disposed of incorrectly.  Read product labels carefully and look for the words: danger, warning or caution. These signal words are required by federal law to be placed on products with any of the following properties:

  • Flammable/Combustible: Can be easily set on fire or ignited
  • Explosive/Reactive: Can detonate or explode through exposure to heat, sudden shock or pressure, or readily reacts with other products or chemicals
  • Corrosive/Caustic: Can burn and destroy living tissue on contact
  • Toxic/Poisonous: Capable of causing injury or death through ingestion, inhalation or absorption
  • Radioactive: Can damage or destroy cells and chromosomal material

If you have unwanted products that are  labeled with any of these terms, you have HHW. It is important to dispose of HHW responsibly in order to minimize the risk of causing damage to yourself, others or the environment.

Disposal Instructions

You may safely dispose of HHW at the Household Hazardous Waste Facility. Before bringing your HHW to the Facility, please follow the instructions below:

  1. DO NOT MIX CHEMICALS TOGETHER! Keep chemicals separate, preferably in their original, labeled containers. If chemicals are not in their original containers, please print the chemical name (if known) on the container.
  2. Place your HHW in a sturdy cardboard box lined with newspaper. Wrap any leaking container in a clear plastic bag. Place the box in the trunk of your car or bed of a pickup truck where it can be easily reached.

Paint Disposal

Household Hazardous Waste is expensive to dispose of properly, but you can help us keep costs down! If you have old paint, please follow these simple suggestions first:

Throw Dried Paint out with Trash

Once paint has dried, it is virtually harmless to the environment. Open all paint cans and check the paint inside. If it is dried, throw the can (with the lid removed) directly into your household trash.

Recycle Good Paint

Open the paint and give it a stir. If the paint stirs into a lumpy consistency or if the liquid and pigment remain separated after stirring, your paint is bad. If it stirs into a smooth, even consistency, your paint is good. Please check with organizations such as Habitat for Humanity or Sojourners Alliance to see if they could use your paint. Good paint may also be brought to the HHW Facility.

Solidify and Dispose of Bad Latex Paint

If your water-based paint has gone bad, please help keep HHW collection costs down by solidifying and disposing of the paint on your own. To solidify water-based paint, mix clumping kitty litter into the paint until it solidifies into one mass. Once latex paint has been solidified in this manner, it can be treated the same way you would treat dried paint–leave the lid off the can and throw it into your regular trash.

Bring Wet Oil-Based Paint to HHW Facility

Oil-based paints pose a greater environmental hazard than water-based paints, so if you have oil-based paints that are not dried out, bring them to the HHW collection facility DURING HOURS OF OPERATION (see above) to be processed with other hazardous materials.
