This is a list of all household hazardous waste accepted items for disposal. Please review when sorting through your hazardous waste.

Hazardous Waste Recyclable Items

Antifreeze ~ Engine Coolant

Residents may drop-off used or unwanted antifreeze / engine coolant at the HHW Collection Facility.

Antifreeze or engine coolant contains ethylene glycol has a sweet taste that if accidentally ingested can have serious and harmful effects.  Symptoms of antifreeze poisoning include severe diarrhea and vomiting.  Coolant containing ethylene glycol should not be disposed of in a way that will result in it being ingested by animals, because of its toxicity. Many animals like its sweet taste. As little as a teaspoonful can be fatal to a cat, and four teaspoonfuls can be dangerous to a dog. 


Batteries can contain lead, mercury, cadmium, lithium, nickel, zinc chloride and other harmful heavy metals and materials.  Many of these metals are recovered in the recycling process.

Disposing of any type of battery in the garbage is illegal and batteries are banned from the trash.  This includes all batteries: AAA, AA, C, D, button cell, 9-volt, and all others, both rechargeable and single use.

Lead-acid batteries,  such as car, motorcycle and marine batteries are also banned.

Fats, Oil & Grease (FOG)

Thinking of frying a turkey?

- Do you know what to do with leftover used cooking oil and grease?

Never wash cooking fats, oil or grease (FOG) down the drain, as they can cause the sewer line to back up into your home. If the drain clogs and causes a sewer line blockage it may cause the back up to flow onto the street and into the storm drains which flow to the Bay.  This material is harmful to the Bay and the creatures that live there.

Recycle it Instead!

The West Contra Costa Integrated Waste Management Authority provides a free residential FOG drop-off program.  Most cooking fats will be turned into bio diesel.  Please do NOT mix with automotive waste (no auto oils or lubricants) – these cannot be separated.  No restaurants will be serviced.  Maximum fifteen (15) gallons per person (three 5-gallon containers please).

Used Oil for Bio-Diesel

West Contra Costa County residents may take their FOG to the West County HHW Collection Facility.

There are numerous locations in West County that accept used cooking oil for use as bio-diesel.  Visit to see an online search engine with a directory of used cooking oil drop-off locations.


Fluorescents Lamps & Tubes

(FREE Drop-off at HHW facility)

Residents may, for free, safely and properly dispose of any and all types of lamps and lights at the West County HHW Collection Facility, including fluorescent tubes, compact fluorescent lamps (CFLs), metal halide lamps, and sodium vapor lamps.

Fluorescent lamps and tubes contain mercury* – a harmful heavy metal.

These lamps and tubes are banned from the trash.

*Mercury is extremely toxic and should generally be handled with care; in cases of spills involving mercury (such as from a broken fluorescent lamp or tube) specific cleaning procedures are used to avoid toxic exposure.  Use extreme caution when cleaning up a broken lamp.  It can be inhaled and absorbed through the skin and mucous membranes.  Mercury can cause both chronic and acute poisoning.

(FREE CFL Drop-off at Home Depot)

Home Depot also collects CFLs – At each store, customers can simply bring in any expired, unbroken CFL bulbs.  CFLs in plastic bags are to be deposited into a collection receptacle located on the front end of the store near the entrance, by the Returns desk or near the exit doors inside the store.

Pharmaceuticals Now Present in the Environment

**News Release May 2012 - Look Below for Additional Drop Off Locations for Pharmaceuticals**

Pharmaceuticals are now being detected in water and soil by scientists worldwide.  A 2002 U.S. Geological Survey (USGS) study found pharmaceutical and personal care product contaminants in 80 percent of 139 streams sampled in 30 states.

Pharmaceuticals enter wastewater treatment plants through either excretion or flushing of unused medications. These pharmaceuticals may not be completely degraded or removed at the wastewater treatment plant. Regardless of the level of treatment, most conventional wastewater treatment cannot effectively eliminate pharmaceutical compounds.

Concern about Pharmaceuticals in the Environment

Researchers suspect that hormones and pharmaceutical compounds in the water may be responsible for effects on wildlife including feminization of male fish, sluggish activity or reduced appetite.  Short and long term human health effects are currently unknown.

In addition, pharmaceutical use in the general population is growing, so more unwanted drugs are generated and being improperly disposed and thus creating increased environmental concerns.

**Announcing Four New Locations to drop off Pharmaceuticals - May 2012**

San Pablo and Pinole Police Departments and the West County Wastewater District office are new drop-off locations for unwanted and expired home-generated pharmaceuticals.  These new convenient locations allow West Contra Costa County residents to properly dispose of old pharmaceuticals and keep them out of the water supply and garbage.  Controlled substances are not allowed in the collection bins per State and Federal Laws.

New Locations:

San Pablo Police Station: 13880 San Pablo Avenue, San Pablo
Pinole Police Station: 880 Tennent Avenue, Pinole
Richmond Police Station: 1701 Regatta Blvd, Richmond

West County Wastewater District Office: 2910 Hilltop Drive, Richmond


Other locations  accepting unwanted pharmaceuticals:
West County Permanent HHW Collection Facility:  101 Pittsburg Avenue, Richmond
El Cerrito Recycling + Environmental Resource Center:  7501 Schmidt Lane, El Cerrito

Mercury Containing Items


There are devices and products that we often use that contain mercury*. 
Mercury is harmful to humans and the environment.  Many of these materials are common and seem safe, but if ingested, absorbed into your skin, or inhaled serious and harmful health effects will result.  

All mercury containing devices and items are banned from the trash.

  • Electrical switches and relays
    – These typically contain about 3.5 grams of mercury each. Mercury switches can be
    found in some chest freezers, pre-1972 washing machines, sump pumps, electric space
    heaters, clothes irons, silent light switches, automobile hood and trunk lights, and ABS brakes.
  • Thermostats that contain mercury
    – There is mercury inside the sealed glass "tilt switch" of the old style thermostats (not the newer electronic kind).
  • Pilot light sensors
    – Mercury-containing switches are found in some gas appliances such as stoves, ovens, clothes dryers, water heaters, furnaces, and space heaters.
  • Mercury gauges
    – Some gauges, such as barometers, manometers, blood pressure, and vacuum gauges contain mercury.
  • Mercury thermometers
    – Mercury thermometers typically contain about a half gram of mercury. Many health clinics, pharmacies and doctor's offices have thermometer exchange programs that will give you a new mercury-free fever thermometer in exchange for your old one.
  • Mercury-added novelties
    – Examples include greeting cards that play music when opened; athletic shoes (made before 1997) with flashing lights in soles; and mercury maze games.

*Mercury is extremely toxic and should generally be handled with care; in cases of spills involving mercury (such as from a broken fluorescent lamp or tube) specific cleaning procedures are used to avoid toxic exposure.  Use extreme caution when cleaning up a broken lamp.  It can be inhaled and absorbed through the skin and mucous membranes.  Mercury can cause both chronic and acute poisoning.

(FREE Drop-off at HHW facility)

Residents may, for free, safely and properly dispose of any and all types of mercury containing items at the West County HHW Collection Facility.

Needles, Syringes & Lancets = “Sharps”

Why You Should Be Careful with Sharps Improper disposal of used or unwanted “sharps” (needles, syringes, lancets and other sharps items) can cause a serious injury and pose health risks to the public and waste workers. Waste workers are exposed to potential needle stick injuries and potential infection when inappropriate containers break open inside garbage trucks or sharps become exposed when sent to recycling facilities. Housekeepers and janitors may also be injured when loose sharps poke through trash bags. Used needles can also cause painful infections and transmit serious diseases, such as HIV and hepatitis.  The LawBeginning on September 1, 2008, State law made it illegal to dispose of home-generated sharps waste in the trash or recycling containers, and requires that all sharps waste be transported to a collection center in an approved bio-hazard sharps container.The California Health and Safety Code defines "home-generated sharps waste" as hypodermic needles, pen needles, intravenous needles, lancets, and other devices that are used to penetrate the skin for the delivery of medications derived from a household, including a multifamily residence or household.Residents can visit the California Department of Resources Recycling and Recovery (CalRecycle) website to find out if the pharmaceutical manufacturer has a free sharps container available. Senate Bill 486, passed in October 2009, required that by July 1, 2010:“…all pharmaceutical manufacturers that sell or distribute a medication in California that is usually intended to be self-injected at home through the use of a hypodermic needle, pen needle, intravenous needle or any similar device, to 1) submit a plan describing their actions to support or provide for the safe collection and proper disposal of the waste devices, and 2) educate consumers about safe sharps management and collection opportunities.”The CalRecycle website that lists the manufacturers who have turned in a plan is residents need more containers they can ask the pharmacy where they get their medications. For further information about obtaining biohazard containers you may contact:  1)     Barnett Medical Services: www.barnettmedservices.com2)     Sharps Compliance Inc.: www.sharpsinc.com3)     Stericycle: www.buysharpsonline.com4)     www.xmeddisposal.com5)     Waste Management: www.thinkgreenfromhome.com6) also has additional informationMost of these companies charge a fee for the containers and are a mail-back system.We do not endorse any of these companies and do not intend this to be a complete list.Thank you for your cooperation.
