Household Hazardous Waste

Many household products contain chemicals that can be hazardous to you, your family, and the environment if not handled properly. These items are considered household hazardous waste (HHW) and are usually labeled with words like caution, warning, danger, poison, flammable, volatile, caustic, or corrosive.

Common HHW products include cleaners, paints, automotive products, pesticides, and garden products.

Preparing to Use UnderTheSink

Follow these recommendations when packaging and transporting your items:

  • Use Original Containers.
  • Clearly Label. Add a handwritten label to unmarked containers with the name of the product if known.
  • Tighten Lids. If missing a lid, pour the chemical into a replacement container made out of the same material as the original package (e.g., metal or plastic) and label it with the name of the product. Attach the empty, original container to the replacement container.
  • Place in a Box. Ensure containers remain upright in a box and line it with plastic or newspaper.
  • Prevent Leaks. Put leaking or damaged containers inside a heavy plastic bag (one bag per leaky container). Then place bags in a plastic bucket or tub.
  • Do Not Mix. Combining chemicals is dangerous.
  • Go Directly to the Facility. Do not leave HHW in your vehicle while completing other errands.

If you do not follow preparation steps carefully, your products may not be accepted at UnderTheSink.
