Introduction
Single-use batteries like AA alkaline cells power many everyday devices, from remotes to flashlights. But when they run out of juice, how should we dispose of them? In Washington State, improper disposal isn’t just bad for the environment — local and state rules are changing to make battery recycling easier, safer, and more consistent for residents.
Why Battery Disposal Matters
Though alkaline batteries manufactured after the 1990s no longer contain mercury, they still include metals and chemicals that can:
- Leach into soils and groundwater,
- Cause fires in landfills or waste collection systems, and
- Harm recycling workers and the environment.
Because of these risks, counties, cities, and the state are pushing safer handling and recycling options.
Current Rules (2026): What You Need to Know
1. Don’t Throw Them in the Trash
In many Washington cities (including Seattle), batteries are banned from household garbage. This includes AA, AAA, C, D, and 9-volt batteries.
General rule of thumb:
- Do NOT toss batteries in your regular trash or curbside recycling bin.
- Even if solid waste staff don’t fine you, improper disposal is dangerous and environmentally harmful.
2. Household and County Disposal Options
Residents in King County and other jurisdictions are encouraged to bring household batteries — including alkaline — to dedicated Household Hazardous Waste (HHW) collection sites.
These sites accept:
- Alkaline household batteries,
- Rechargeable batteries (nickel-metal hydride, lithium-ion),
- Button cells,
- Car/lead-acid batteries (at appropriate facilities).
Note: Some county programs ask that you bag batteries and bring them in limited quantities, and damaged batteries may need special handling.
3. Recycle Through Retail and Partnership Programs
You can also recycle batteries through:
- Call2Recycle locations at participating stores,
- E-Cycle Washington drop-off programs,
- Local hazardous waste events.
These options provide safe, accessible ways to hand off old batteries for proper processing.
The New Washington Battery Recycling Law (Statewide EPR)
What’s Changing — Producer Responsibility
Washington State passed a landmark battery stewardship law (part of RCW 70A.555 and related rules in WAC 173-905) that will transform how batteries are handled statewide.
Key Points:
- Battery manufacturers and producers must fund and operate a statewide battery recycling system — not residents.
- Portable batteries (which include AA alkaline) will be covered beginning January 1, 2027.
- Medium-format batteries (like those in e-bikes) will follow in January 2029.
- Producers must have an Ecology-approved stewardship plan before selling in Washington, or retailers will be barred from selling those batteries.
This kind of law — often called Extended Producer Responsibility (EPR) — shifts costs and logistics from consumers and governments to the companies that profit from selling battery-powered products.
Effective Timeline
| Date | What Happens |
|---|---|
| Jan 1, 2027 | Portable batteries must be included in stewardship plan collection sites. |
| July 1, 2027 | Retailers can only sell covered batteries from participating producers. |
| Jan 1, 2029 | Medium-format batteries enter the program. |
| Jan 1, 2030 | Marking requirements (chemistry, crossed-out trash bin symbol) take effect. |
This timeline means that by 2027, residents should see more collection sites, free recycling services, and clearer guidance on dropping off used batteries.
Practical Steps for Residents
- Store old batteries safely — keep terminals covered with tape to prevent shorting.
- Locate a drop-off site — use HHW facilities, Call2Recycle partners, or special waste events.
- Recycle regularly — don’t accumulate large piles; a hazard can develop.
- Follow the evolving statewide program as 2027 approaches for broader options and convenience.
Conclusion
Washington State’s approach to battery disposal is shifting from “do your best locally” to a coordinated, statewide system backed by battery producers. For residents today, that means never throwing AA alkaline batteries in the trash and using designated recycling programs. By 2027, a formal statewide battery stewardship program will make recycling cleaner, easier, and more consistent across the state.
Frequently Asked Questions
Can I throw alkaline AA batteries in the trash in Washington?
In many areas, no. Many Washington jurisdictions ban batteries from garbage due to fire risks. Recycling is recommended statewide.
Are AA batteries considered hazardous waste?
They are not classified the same as older mercury batteries, but they still pose environmental and fire risks and should be recycled.
When does the new Washington battery law take effect?
Portable batteries like AA alkaline batteries are covered beginning January 1, 2027.
Final Thoughts
If you’re holding onto old AA alkaline batteries, the best option in Washington State is:
✔ Recycle them at an approved drop-off location
✔ Never place them in trash or curbside recycling
✔ Watch for expanded statewide recycling options starting in 2027
Washington is moving toward a cleaner, safer battery recycling system — and residents play an important role.
