Hazardous Waste Disposal and Special Programs
It is illegal to put hazardous waste into any dumpster or cart (landfill, recycle, or organics). This includes batteries, motor oil, paint, pesticides, cleaning chemicals, etc. Residents can drop off hazardous waste to the Central Contra Costa Sanitary District or drop off select items in their own community!
It is illegal to dispose of televisions, computer monitors and most other electronics in the garbage. The cathode ray tubes (CRTs) contain lead and could contaminate water supplies.
Your unwanted and obsolete electronic equipment and appliances are one of the fastest growing waste streams. When discarded in landfills, these items not only lock up components that contain valuable and reusable natural resources, they also contain toxic chemicals that can contaminate soil and groundwater.
- Residents: Residents can dispose of unwanted electronics (including monitors and table top-size televisions) curbside at no additional cost on their “Reuse” Day (see Residential Reuse and Cleanup Program for more information). Residents can also dispose of electronic items at no additional charge by calling us at (925) 685-4711 for an e-waste pickup.
- Multi-Family: Property managers can collect e-waste and call for a free e-waste pickup.
Another option is donating your equipment to a non-profit or school; you can claim it as a tax deduction.
Household Hazardous Waste
Household hazardous wastes should never be thrown into the trash or washed down the household or storm drains.
Hazardous chemicals, pesticides and paints can "pass through" treatment processes because wastewater treatment plants are not designed to remove hazardous chemicals from wastewater. Storm drains flow directly to the Bay without any treatment at all. Groundwater used for drinking or irrigation can be contaminated when household waste products are poured onto or seep into the ground.

Motor oil can be recycled using your curbside recycling collection:

- Pour used motor oil into the supplied disposal container and carefully seal the container.
- Place the sealed container next to your blue recycling cart.

- Place used filters in the bag provided by Republic Services and attach to the oil container.
Many auto service stations, auto parts stores and oil changers also accept used motor oil and oil filters for recycling. Call Contra Costa County's recycling hotline at 1-800-750-4096 for your nearest location.
