Household Hazardous Waste Overview


Household Hazardous Wastes (HHW) are leftover household products that can catch fire, react, or explode under certain circumstances, or that are corrosive or toxic. Typically, these items are labeled with terms like:

  • Corrosive
  • Caution
  • Combustible
  • Danger
  • Flammable
  • Poison
  • Toxic
  • Warning

While not regulated like Industrial Hazardous Waste, Household Hazardous Waste is just as dangerous to residents and the environment if not properly disposed of.

The HPC helps divert more than 150 tons of HHW a year from entering the Cinder Lake Landfill, and is the best solution for disposal of Household Hazardous Waste.

In order to utilize the HPC's services, please review the following requirements, guidelines, and limits. Small Businesses can refer to the Small Business Waste Program (SBWP) for information on Industrial Hazardous Waste.
