What happens to items collected from HHW?

  • Used motor oil, antifreeze and vehicle batteries are recycled by companies specializing in recycling each commodity.
  • Unusable hazardous materials will be disposed of properly by a hazardous waste contractor.
  • Appliances are recycled as scrap metal after the removal of refrigerants.
  • Tires are recycled into crumb rubber.
  • Non-hazardous materials are sorted and recycled as possible and/or disposed of as municipal solid waste.

Alternative methods to dispose of HHW

You can also check out the ​Re​cycle Wizard to determine the safest way to dispose hazardous waste​. 


Alkaline and carbon-zinc batteries are non-hazardous. Typically batteries in sizes A, AA, AAA, C and D, should be bagged and tied and placed in your garbage container.

Rechargeable batteries that are nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), lithium ion (Li-ion), or small, sealed lead batteries, weighing less than two pounds can be recycled through the HHW program or a battery vendor. Do not place batteries in your recycling container. 

Latex Paint

Allow small amounts of latex paint to dry and harden. Place open can of dried paint in the garbage container. Place lid in container separately. Large amounts of latex paint can be solidified with an agent found in the hardware store or mix in equal amounts of kitty litter. Once the paint is solid you can place it in the garbage container.

Motor Oil and Car Batteries

Motor oil and car batteries may be taken to some local auto parts stores for free. Call the auto parts store first to confirm. 

City disposal facilities accept car batteries, up to five (5) gallons of motor oil per residence, household appliances, and up to five (5) tires (no oversized tires) per residence per year. Bring your current Phoenix Municipal Services bill and matching I.D.


Use or burn up propane in small (1 lb) canisters. Take cylinders or tanks to a propane dealer or scrap metal recycler for recycling.
