Hazardous Waste


Toxic household materials like motor oil/oil filters, anti-freeze, paints, solvents, cleaners, and old batteries are too hazardous to throw in the trash.  These products cannot be put into your residential trash because they cannot be disposed of in the landfills without risking contamination to groundwater and they cannot be dumped into storm drains without contaminating our oceans. They also cannot be dumped into the sewers as they kill the beneficial bacteria needed to treat sewage.

OCWR Battery Collection 2

Important Notification about Batteries (issued on July 28, 2023): OC Waste & Recycling (OCWR) is issuing an alert to remind all county residents and businesses of the importance of proper disposal of hazardous waste, especially batteries. Improperly disposed batteries continue to be the leading cause of fires in the waste system, which endangers lives, causes expensive damage and disrupts waste services. "Batteries can become compacted and punctured when thrown into ordinary bins and subsequently landfills, causing them to easily explode and cause fires," said Tom Koutroulis, Director of OC Waste & Recycling. "With the fire season and high temperatures upon us, the proper disposal of batteries and hazardous waste is critical to minimizing these dangers." 

When visiting any of the four Household Hazardous Waste Collection Centers to dispose of unwanted household hazardous waste, ask for a FREE battery collection recycling bucket - available while supplies last. For more information on the proper disposal of household hazardous waste visit OCLandfills.com/hazardous-waste or follow @OCWaste on social media.

Proper Disposal 

It is dangerous and illegal to discard household hazardous waste into the trash, a storm drain, or down the sewer drain. Instead, use up the product as intended or take the unused portion to a Household Hazardous Waste Collection Facility. Uncontaminated used oil, oil filters, antifreeze, and automotive batteries may also be taken to a local certified collection center throughout the County, including most auto parts stores and gas stations.
