What is Household Hazardous Waste & Electronic Waste?
Household hazardous waste (HHW) is any material (gas, liquid, or solid) from a home that may pose a health threat to people, animals, or the environment if handled or disposed of improperly. Common examples include chemicals labeled "poison," "toxic," "flammable," "corrosive," or "reactive," electronic devices, batteries, medical sharps, paint, motor oil, and products containing mercury (including fluorescent bulbs).
HHW should never be thrown into the trash or poured down the sink, sewer or storm drains. Improper disposal may injure refuse workers, pollute ground water, waterways, and the ocean, potentially destroying marine life. For these reasons, improper disposal is illegal.
How Do I Dispose of HHW?
If you would like to dispose of HHW and electronic waste, the City offers 8 free collection events each year for City of La Mesa residents. HHW can be dropped off by appointment only and there is a limit of 15 gallons, 125 pounds, or five monitors and/or TVs.
If you live within the city limits, please call EDCO at 619.287.5696 ext. 4270 or email to schedule an appointment. Be sure to include your name, address, and telephone number.
How To Properly Dispose of Lithium-Ion Batteries
Watch this EDCO video to learn about proper lithium-ion battery disposal, including the dangers of throwing lithium-ion batteries in curbside trash and recycling.
What are lithium-ion batteries?: A lithium-ion battery is a rechargeable battery that uses lithium ions to create and store energy. Lithium-ion batteries can be found in everyday electronics, such as smartphones, laptops, power tools, and toys.
What happens when lithium-ion batteries are improperly disposed of?: Lithium-ion batteries found in household electronics are often improperly placed in household trash or recycling bins, which poses a hazard to the community. When trash collection trucks and recycling facilities crush or jostle these batteries, they have a high potential to combust, leading to dangerous blazes. If located in a deep trash or recycling pile, everything can catch fire, creating a critical situation. Unlike typical fires, lithium-ion-fueled fires cannot be put out with water. Water does not deprive the oxygen of fire, it merely interacts with it. The batteries need to be isolated and given space for the fire to die down. To avoid putting truck drivers and community members at risk, DO NOT put lithium-ion batteries in curbside trash or recycling bins.
Since many electronics can be recycled, can they be put in the curbside recycling bin?: This is a common misconception. Electronics can be recycled, however, they cannot be placed in household trash and recycling bins. In California, it is illegal to dispose of them in this way. In addition to the fire hazard they pose, municipal waste and recycling facilities are not built to handle these types of batteries. Additionally, old lithium-ion batteries and electronics that end up in landfills can leach toxic, corrosive chemicals into the soil and water table, endangering human health and the environment.
How can lithium-ion batteries be properly disposed of?: All batteries and electronic waste must be properly disposed of at household hazardous waste facilities or events. They should NEVER be placed in trash or recycling collection containers.
