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. 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.

Businesses, Government Agencies & non-Profits

For more information on proper disposal of hazardous waste from businesses (including farms), government agencies & non-profits please visit our Business Resources page. Additional information is available at the State of Hawai‘i DOH Hazardous Waste Section website, click for a listing of Hazardous Materials Management companies (it is the “Haulers & Recyclers List” or the “Permitted Used Oil Transporters/Processors” list). For fact sheets on disposal or clean ups of hazardous substances, pollutants or contaminants visit the State of Hawai‘i Department of Health Office of Hazard Evaluation & Emergency Response.

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.
