Please note: Automotive, motorcycle, and industrial batteries are not accepted at the community battery disposal bins but can be dropped off at the City’s HHW Facility.

Warning: Lithium button batteries are very dangerous to children and pets. Improper handling or storage may result in death or injury. Batteries are also fire hazards. Click here to read about 9 Volt battery safety.

FREE Oil Change Kit

If you’re a Do-It-Yourselfer and like to change your own oil and filter, pick up a FREE Oil Change Kit from the Household Hazardous Waste facility. This kit contains everything you need to safely change and transport your used oil and filters to a Certified Used Oil Collection Center.

Recycle Used Oil

Did you know that used motor oil can be cleaned and used again and again? Used motor oil and filters can be dropped off at Certified Used Oil Collection Centers for proper recycling and disposal. Click here to find the closest centers to you in the Thousand Oaks area to drop off. You can also make an appointment to drop off oil and filters. The following things should be kept in mind when planning to dispose of used oil and filters: 

• Call centers for hours of operation, quantity limits, and to find out whether filters are accepted. Up to 5 gallons of oil per day, per resident, are usually accepted, but this can vary from center to center.
• $0.40 cents per gallon reimbursement is available.
• Place oil in five-gallon (or smaller) containers that have tight seals and are pourable. 
• For those locations that accept filters, drain and place in a plastic bag.
• It is illegal to leave oil after business hours.
• It is illegal to dispose of used oil in the trash, on the ground, or in the storm drain system.
• Do not contaminate oil by mixing it with any other automotive or household products- it will not be accepted.

Using up a product for its intended use or giving the material to someone who can is the best practice for any household product and the principle behind the City's Material Reuse Program. This program takes useable household products collected at the City's weekly Household Hazardous Waste (HHW) Collection events and makes them available to the public FREE of charge, saving the City disposal costs in addition to saving residents on the costs of purchasing new products.
