Some products we use every day contain hazardous materials and cannot be thrown away in the trash.
Common items may be hazardous because they have one or more of the following properties:
- They are toxic: poisonous when ingested, inhaled or touched (such as rat poison or bleach).
- They are flammable: Easy to ignite (such as lighter fluid and paint removers).
- They are corrosive: eats away materials and living tissue by chemical action (such as oven cleaner).They are reactive: creates an explosion or generates deadly vapors (such as bleach mixed with ammonia
See below for free and safe disposal options for residents.

Batteries contain toxic materials and it is a violation of State law to throw them away in the trash. Some batteries retain a residual charge even after they can no longer properly power a device--their power has not been completely used up and they can combust or spark, causing a fire or other safety incident. Recycle them safely by following the steps below:
- Bag it or tape it. Place each battery in its own clear plastic bag before placing it in a storage container. If a bag isn’t available, you can tape the terminals with clear packing, non-conductive electrical or duct tape (do not use masking, painter or Scotch tape). Make sure the battery label is visible.
- Store the batteries in a cool, dry place. Incidents can occur when batteries (or the devices they power such as a cellphone or tablet) are exposed to moisture or warm temperatures. Store them in a plastic container, not metal or cardboard.
- Keep an eye out for damaged batteries. If you see a swollen or bulging battery, immediately put it in sand or kitty litter in a cool, dry place and bring it to the County household hazardous waste drop-off program as soon as possible.
- Drop them off within six months. Old batteries should never be stored longer than six months before bringing to one of the locations listed below for recycling:
- Davis Ace Hardware at 3rd & G Sts.
- Davis Food Co-Op, 620 G Street
- Davis Senior Center, 646 A Street

State law has made it illegal to dispose of home-generated sharps waste in the trash and requires that all sharps waste be transported to a collection center in an approved sharps container.
Home-generated sharps waste includes 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 or multifamily residence.
The following are some of the disposal options available to you for disposal of sharps waste:
Yolo County Household Hazardous Waste (HHW) Drop-off Days
During HHW drop-off events, home generated sharps in approved sharps collection containers are accepted for free and safe disposal. Place sharps waste in a red sharps container or a rigid plastic container, such as bleach or detergent bottles. The lid of the container should be tightly closed and taped shut with “Sharps Waste” written on the outside of the container.
Drop-Off at Recology Davis
Recology Davis accepts sharps waste for free drop-off at their CRV redemption center during buyback hours, Monday through Friday from 9:30 a.m. to 2:00 p.m. and Saturday 8:00 a.m. - 4:00 p.m. Sharps are only accepted during the CRV redemption hours and may not be dropped off after hours. Place sharps waste in a red sharps container or a rigid plastic container, such as bleach or detergent bottles. The lid of the container should be tightly closed and taped shut with “Sharps Waste” written on the outside of the container. Recology Davis employees will receive the sealed sharps container and place it in their sharps kiosk for proper disposal.
Other options for safely disposing of used sharps are available on the California Department Of Public Health webpage. These options include the following:
- Mail-Back Service: There are some companies that offer pre-paid sharps containers that can be mailed-back when full for safe disposal.
- Hospital Take Back: Some hospitals might take back needles (sharps) from those patients who go to the hospital for regular outpatient services.
Sharps Disposal Containers
Home generated sharps must be placed in an approved red sharps container. The sharps container is puncture-resistant and, once sealed, cannot spill. This container is considered full when it has been filled to three quarters of its capacity. At this point, the container should be permanently sealed and returned to a disposal location as soon as possible (see the list above for sharps disposal options). At that time a new container should be obtained. Sharps containers may be purchased at most pharmacies and drug stores. Residents can also use a metal or a rigid plastic container, that has a tight fitting lid--such as a coffee can or detergent bottles. The lid of the container should be tightly closed and taped shut with “Sharps Waste” written on the outside of the container.

How often do you need to change your motor oil?
Χ a) 3,000 miles
Χ b) 3 months
✓ c) check your owner's manual
Needing to change your car’s oil at 3,000 miles is a myth. Auto makers now are recommending oil changes at 5,000, 7,000 or even 10,000 miles. Following the 3,000 mile myth generates millions of gallons of waste oil every year which can pollute California’s natural resources.
USED OIL FACTS
- Each year, millions of gallons of used oil are illegally poured down drains, sewers or disposed in the trash.
- One gallon of used motor oil can pollute one-million gallons of drinking water
- Used motor oil can be RE-REFINED into new oil that is just AS GOOD AS NEW.
- Before it is drained, an oil filter can contain over a pint of used oil.
- Oil filters containing oil SHOULD NOT be thrown into the trash. Remember to recycle!
- It takes one gallon of used oil to produce 2.5 quarts of re-refined oil.
- If all used motor oil generated by the public was collected and re-refined, it would provide enough oil for more than 5 million cars each year.
- State agencies are now mandated to use re-refined oil, and have reported no problems resulting from its use.
- The CA Highway Patrol spends about $110,000 on 22,000 gallons of re-refined engine oil and maintains 3,800 enforcement vehicles that drive more than 110 million miles per year.
- Extensive laboratory testing and field studies show re-refined oil is equivalent to virgin oil.
- Used oil can contain such contaminants as lead, magnesium, copper, zinc, chromium, arsenic, chlorides, cadmium, and chlorinated compounds. Oil poured down drains or onto the ground or put in the garbage can work its way into our ground and surface waters and cause serious pollution.
