What is household hazardous waste (HHW)?

HHW is the hazardous material from a home — products that can catch fire, react, corrode, or poison people and waterways if they are landfilled or poured away.

Typical HHW

• Paint and paint-related products
• Motor oil and other automotive fluids from the home
• Household batteries and bulbs
• Cleaning chemicals, solvents and similar household chemicals
• Household chemicals you are told not to pour down a drain or put in trash

That list is a guide to the category, not a promise that a specific product will be taken on a specific day — confirm accepted items at CleanLA or LASAN before you go.

Where it goes in LA County

• One-day county HHW / e-waste events — weekly, usually Saturdays, free to LA County residents.
• City of Los Angeles S.A.F.E. Centers — generally Saturday–Sunday, 9am–3pm, with per-center exceptions.
• LA County permanent centers in Palmdale and Signal Hill — check the official schedule for hours.

Transport limit: 15 gallons or 125 lbs per trip.

Not accepted

Solar panels are not accepted at county HHW events or permanent centers. Pasadena’s own city e-waste / shredding days also do not include HHW — HHW needs a county event or a permanent center.

Never do this

• Never put HHW in curbside trash or a curbside bin.
• Never mix different chemicals together.
• Never pour oil, paint or chemicals into a storm drain.
