How to Dispose of CFL Bulbs Safely

CFL (compact fluorescent lamp) bulbs contain a small amount of mercury — typically 3–5 milligrams per bulb. This makes them hazardous waste that cannot go in regular household trash in most US states. Here's how to dispose of them safely, where to recycle them for free, and what to do if one breaks before you can get it to a recycling location.

Why CFL Disposal Matters

Mercury is a potent neurotoxin. While the amount in a single CFL is small, millions of improperly disposed CFLs in landfills leach mercury into soil and groundwater over time. The EPA estimates that if all CFLs sold in the US were recycled rather than landfilled, it would prevent hundreds of pounds of mercury from entering the environment annually.

The good news: recycling CFLs is free and easy — major retailers accept them at no charge.

Where to Recycle CFL Bulbs (Free)

Retail Drop-Off Locations

Home Depot: Accepts CFLs at in-store recycling bins near the entrance or customer service area. No purchase required. Accepts any quantity.
Lowe's: Accepts CFLs at in-store recycling collection points. No purchase required.
IKEA: Accepts CFLs at store recycling stations.
Batteries Plus Bulbs: Accepts CFLs and other bulb types for recycling.

Municipal Programs

Hazardous waste collection events: Most counties hold periodic household hazardous waste (HHW) collection days where CFLs are accepted. Check your local government or county website for dates.
Permanent HHW facilities: Some counties have year-round drop-off facilities for hazardous household materials including CFLs.

How to Prepare CFLs for Transport

CFLs are fragile and contain mercury vapor. Handle them carefully when transporting to a recycling location:

Keep CFLs in their original packaging if possible — the cardboard provides cushioning and contains any breakage
If you don't have the original packaging, wrap each bulb individually in newspaper
Place wrapped bulbs in a cardboard box or paper bag — don't let them roll around loose
Keep the box upright during transport
If a bulb breaks during transport, seal the pieces in a plastic bag before continuing

What to Do If a CFL Breaks

A broken CFL releases mercury vapor. The amount is small but the room should be ventilated before cleanup. Follow the EPA's recommended procedure:

Immediately After Breaking

Open windows and doors in the room — ventilate for at least 15 minutes
Leave the room during ventilation — keep people and pets out
Turn off central air conditioning or heating to prevent mercury vapor from spreading through the HVAC system

Cleanup

Put on rubber or latex gloves before touching any pieces
Scoop up large glass pieces with stiff cardboard — do not use your bare hands
Use damp paper towels to pick up remaining small pieces and powder
Use tape (duct tape or packing tape) to pick up fine particles from hard surfaces
On carpet: cut out and remove the affected section if possible; otherwise use tape to lift particles
Do not use a vacuum cleaner — it spreads mercury-containing powder through the air and contaminates the vacuum

Disposal of Cleanup Materials

Place all cleanup materials (glass, paper towels, tape, gloves) in a sealed plastic bag
Place that bag inside another sealed plastic bag (double-bag)
Take to a Home Depot, Lowe's, or municipal hazardous waste facility — do not put in regular trash

After Cleanup

Continue ventilating the room for several hours if possible
Wash hands thoroughly with soap and water
The first time you vacuum the area after cleanup (next day or later), remove the vacuum bag immediately and seal it in a plastic bag for disposal

CFL Disposal by State

Rules vary by state:

California: CFLs are classified as universal waste — disposal in regular trash is prohibited. Recycling is required.
Maine, Minnesota, Vermont, Washington: Similar prohibitions on CFL landfill disposal.
Most other states: Household disposal in trash is technically permitted but strongly discouraged. Commercial/business disposal is more strictly regulated.

Regardless of local rules, recycling is always the right choice.

Frequently Asked Questions

How much mercury is in a CFL bulb?

Modern CFLs contain 3–5 milligrams of mercury — about the size of the period at the end of this sentence. Older CFLs (pre-2007) may contain up to 15mg. For comparison, old mercury thermometers contained about 500mg. The amount in a CFL is small but still warrants proper disposal.

Is it dangerous to have a CFL in my home?

No — an intact CFL poses no mercury risk. The mercury is sealed inside the glass tube. The risk only occurs if the bulb breaks. Handle CFLs carefully to avoid breakage, and dispose of them properly when they burn out.

Can I mail CFLs for recycling?

Yes — mail-in recycling programs exist for CFLs. Search for "CFL mail-in recycling" or check LampRecycle.org for current programs. Mail-in is more convenient if you don't have a nearby drop-off location, though it typically involves a small fee for the prepaid shipping kit.

What if my local Home Depot or Lowe's doesn't have a recycling bin?

Ask at customer service — some stores keep the collection bin in a less visible location. If the store genuinely doesn't participate, use Earth911.com to find the next nearest option, or save CFLs until your county's next hazardous waste collection day.
