Residential Household Hazardous Waste


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

  • Acid
  • 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 diverts more than 100+ tons of HHW a year from entering the Cinder Lake Landfill, and is the best solution for disposal of Household Hazardous Waste.
