Household Hazardous Waste:

Household Hazardous Waste Household hazardous wastes (HHW) are common household items that contain corrosive, toxic, ignitable, or reactive ingredients and should be handled, stored, and disposed of properly.
  • Corrosive - Eats away substances - cloth, metals and skin.
    Acids and caustics - Battery acid, Pool chemicals, Toilet/drain cleaners
  • Flammable - Ignites easily.
    Gasoline - Lighter fluids - Motor oil, Paint thinner, Propane cylinders
  • Reactive - Creates explosion or deadly fumes.
    Ammonia and Bleach mix, Chlorine - Fertilizers, Cyanides
  • Toxic - Poisonous or lethal when swallowed, touched or inhaled.
    Antifreeze - Pesticides, Rat poison - Weed killers

Cleaners, batteries, paint, oils, electronics, and fluorescent lights are examples of HHW. When used or disposed of improperly these products are a source of potential harm to our bodies and/or the environment. Contaminants from HHW can include cadmium, mercury, lead, benzene, ethylene glycol, and polychlorinated biphenyls (PCBs).

Warning labels, such as poison, danger, and caution, identify products that are hazardous when used improperly. However, there are many products in our homes that do not have warning labels that may contain hazardous materials when broken or disposed of improperly. For example, fluorescent lights, thermostat and appliance switches, batteries, children’s shoes that light up, and thermometers all contain mercury. Electronics contain many heavy metals that can contaminate the groundwater or air if illegally dumped or burned.

The local hazardous waste management program in King County, Washington has developed an extensive list of household hazardous products available at their website. The rollover information describes how to dispose of these items in their community and the link on each product provides information on potential hazards and safer alternatives.

Contaminants of Concern:

Contaminants of concern will be specific to the household hazardous waste product. Batteries are a particularly significant source of metal contamination. Even after 80% of lead-acid automotive batteries are recovered for recycling, the remaining 20% are estimated to contribute 66% of the lead in municipal solid waste nationally. Household batteries account for approximately 90% of the mercury, though that level has been declining greatly as manufacturers remove mercury from alkaline batteries. Nickel-cadmium batteries may be responsible for up to 52% of the cadmium. Another study has estimated that 27% of the lead and 9% of the cadmium are contributed by consumer electronic goods.

Implementing Solutions:

Inform your community about the dangers associated with HHW with the intention to reduce, recycle, and dispose of HHW properly.

Use safer alternatives to hazardous household cleaning products. Many resources such as Alaska Community Action on Toxics' Green Cleaning Guide and Recipe Book are available online.

Set up a Reuse/Exchange Center for Household Hazardous Waste to ensure products are used up instead of being disposed of.
