Hazardous Household Waste

There are products in our homes that are highly toxic and extremely hazardous to the environment. These items cannot be easily recycled or disposed of in the landfill due to the risk of contamination of our drinking water, soil and air. Additionally, there are environmentally-friendly options for the proper disposal or recycling of these materials.  The State of Hawai‘i Department of Health also has an Office of Hazard Evaluation & Emergency Response which lists various fact sheets on managing hazardous substances, pollutants or contaminants. For more information on electronic waste see our electronic waste page.

Customers should first inquire if manufacturers, producers and retailers of hazardous materials offer take-back options for unused material or products that need disposal.  Consumers should also purchase safer, more environmentally-friendly alternative products such as LED light bulbs or rechargeable batteries to reduce the amount of hazardous materials generated.

Household Hazardous Waste

The County of Hawai‘i promotes proper Hazardous Waste Recycling & Disposal through various program and private efforts.  Select the topic from the list below to learn more.


Please visit our Business, Farm & Agency Hazardous Waste page.

Buy only what you need and properly use it all, there will be less chance your business will need to dispose of leftover hazardous materials.  By law the County of Hawai‘i cannot accept hazardous waste from businesses, agencies, farms and non-profits.

Safety Rules For Household Hazardous Waste (HHW) Collection Events

These rules are for your safety and the safety of the staff conducting these events.  Please kōkua and thank you for doing your part to keep these events safe for all participants.

      • Remain in your vehicle unless directed by authorized personnel.  Please advise staff, when they approach your vehicle, what you want them to collect to make sure they know what to unload.
      • Prior to arriving at the event, place your HHW items in your trunk or truck bed.  Make sure your trunk can be unlocked or opened remotely, practice doing so at home.  If you don’t have a trunk or truck bed, preferably place your materials in unlocked unoccupied backseat area.
      • No container returns.  Due to infection transmission hazard all containers brought to the event will not be returned and should be disposable.  If you want to keep your container transfer the material into a safe disposable container prior to the event.
      • To minimize interactions, please label your HHW items (if possible) and make sure that your HHW items are easily distinguishable and separate from anything else in your trunk or truck bed.  Hiding HHW items under or amongst regular garbage only slows the process and may result in missed items.
      • Six (6) foot physical distancing is recommended.
      • If you are under government ordered quarantine or isolation, feeling ill or showing symptoms of illness please consider postponing your participation in our event or designate someone else to drop off your materials.
      • You may pull over to the side of the event area safely after the drop-off area to check that your trunk/tailgate is closed properly or if the staff may have inadvertently missed an item.

If you cannot make it to one of our events or if you have something that is not acceptable at our events there are private companies that can service your needs for a fee. Please refer to the Business, Farm & Agency Hazardous Waste page for immediate disposal options.
