Some products we use every day contain hazardous materials and cannot be thrown away in the trash.

Common household items may be hazardous because they may be toxic, flammable, corrosive or reactive.  

See below for free and safe disposal options for residents.

Household Hazardous Waste Disposal Guide

Other items that cannot be thrown away in the trash:

Used tires: When buying new tires, most dealers will take back your old tires. Used tires can be taken to the Yolo County Central Landfill. Fees may apply.

Refrigerators and microwaves: These can be recycled at the Yolo County Central Landfill. Fees may apply. 

The California Department of Toxic Substance Control website has information on other toxic products, including treated wood, lighting, packaging and cadmium and lead in jewelry.

Batteries

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 household batteries safely by following the steps below:

1. 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.
2. 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.
3. 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.
4. 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, 815 3rd Street
• Davis Food Co-Op, 620 G Street
• Davis Senior Center, 646 A Street
• CVS Pharmacy, 1550 E. Covell Blvd.
• CVS Pharmacy, 1471 W. Covell Blvd.
• Nugget Market, 1414 East Covell Blvd.
• Nugget Market, 409 Mace Blvd.
• Recology Davis Recycling Center, 2727 2nd Street (during buyback hours only: Monday – Friday: 9:30 a.m. – 2 p.m. and Saturday: 8 a.m. – 4 p.m.) 
• Rite Aid, 655 Russell Blvd.

Per State law, rechargeable batteries can be recycled at any store that sells a rechargeable battery.  In addition, the Yolo County Central Landfill also takes rechargeable batteries for recycling. For locations where you can recycle rechargeable batteries and cell phones, visit Call2Recycle.org.

Americans purchase approximately three billion household batteries each year, or about ten batteries per person. Household batteries contain metals that are potentially toxic, including cadmium, zinc, lithium, and nickel.  Help us reduce toxic waste--switch to rechargeable batteries!

More information on batteries. 

Car Batteries: Automotive batteries can be taken to the Yolo County Central Landfill Recycling Center for free drop-off daily during normal business hours. State law requires stores to accept your old battery upon the purchase of a new battery.

Residents can dispose of fluorescent bulbs for free at these locations:

• Ace Hardware, 1350 E Main St., Woodland
• Home Depot, 1860 E Main St., Woodland (CFLs only)

Pesticides

If you have pesticides (liquid or solid) that you no longer need, they must be disposed of properly so that they do not harm you or the environment. Any leftover pesticides must be taken to the Yolo County Household Hazardous Waste Facility. Do NOT recycle OR rinse empty pesticide containers. Residents may place empty pesticide containers in the trash.

Medications

To prevent environmental contamination, prescription and over-the-counter medication should never be flushed down a toilet or thrown in the trash. Fortunately, there is a state-wide program that is paid for by the pharmaceutical industry to safely collect and dispose of medications.

If you have unwanted, unused and/or expired over-the-counter or prescription medicines you can bring them to the locations listed below. Contact each location for hours. More information on safe medication disposal drop-off and accepted items. Free mail-back options are also available.

Sharps

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. Fortunately, there is a state-wide program that is paid for by the pharmaceutical industry to safely collect and dispose of used sharps.

In addition to the programs through the Med-Project, there are other local options available:

• Yolo County Household Hazardous Waste (HHW) Drop-off Days. During HHW drop-off days, 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.

OIL CONTAINERS:  When possible, keep waste in its tightly sealed original container. Label any material that is not in its original container. Do not use leaking containers. If a container is leaking, place the entire contents into a tightly sealed, labeled plastic container.

TRANSPORTING WASTE:  Keep containers upright while transporting to prevent spills. Transport in the trunk of your car or secured in your truck bed. Do not transport more than 125 pounds or 15 gallons.

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.

For more information, visit CalRecycle's website and the CalRecycle Check Your Number database to find the manufacturer-recommended oil change intervals for most vehicles (2000-2020).

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.
