How to Dispose of Old Light Bulbs

How to Dispose of Old Light Bulbs

Not all light bulbs can go in the regular trash. Some contain hazardous materials like mercury that require special handling. Here's exactly how to dispose of every common bulb type safely and responsibly.

Quick Reference: Disposal by Bulb Type

Incandescent and Halogen Bulbs

Incandescent and halogen bulbs contain no hazardous materials and can go in regular household trash in most areas. However, the glass can break and injure sanitation workers, so wrap them before disposal:

1. Let the bulb cool completely before handling
2. Wrap in the original packaging, newspaper, or a paper bag
3. Place in a sealed plastic bag for extra protection
4. Put in the regular trash

Some areas have glass recycling programs that accept incandescent bulbs — check with your local recycling program.

LED Bulbs

LED bulbs contain no mercury and are not classified as hazardous waste. They can go in regular trash when wrapped safely. However, LEDs do contain small amounts of metals (lead, arsenic, nickel) in the circuit board components, so recycling is the more responsible option when available.

Disposal options for LED bulbs:

• Regular trash: Wrap in original packaging or newspaper, seal in a plastic bag
• Retailer recycling: Home Depot and Lowe's accept LED bulbs for recycling at in-store collection bins
• Municipal recycling: Some areas have electronics recycling programs that accept LED bulbs — check Earth911.com for local options

CFL Bulbs (Compact Fluorescent)

CFL bulbs contain mercury — typically 3–5 milligrams per bulb. This is enough to contaminate groundwater if bulbs are landfilled in large quantities. Most US states prohibit CFL disposal in regular trash.

How to dispose of CFLs:

• Home Depot: Accepts CFLs for free recycling at in-store collection bins — no purchase required
• Lowe's: Also accepts CFLs at in-store recycling bins
• IKEA: Accepts CFLs at store recycling stations
• Municipal hazardous waste: Most counties hold periodic hazardous waste collection days — check your local government website
• Earth911.com: Enter your zip code to find the nearest CFL recycling location

If a CFL breaks before disposal: Do not put broken CFLs in regular trash. Place the pieces in a sealed plastic bag and take to a recycling location. Follow the EPA cleanup procedure for broken CFLs (ventilate the room, use damp paper towels to collect fragments, do not vacuum).

Fluorescent Tubes (T8, T12, T5, Circline)

Fluorescent tubes contain more mercury than CFLs — typically 5–15 milligrams per tube depending on age and type. They require the same special disposal as CFLs.

How to dispose of fluorescent tubes:

• Home Depot and Lowe's: Accept fluorescent tubes at in-store recycling bins
• Municipal hazardous waste collection: Most counties accept fluorescent tubes
• LampRecycle.org: Find mail-in recycling programs for fluorescent tubes
• Earth911.com: Local recycling finder by zip code

Transporting fluorescent tubes: Tubes are fragile and contain mercury. Transport carefully — keep them in their original packaging or wrap in newspaper. If a tube breaks during transport, seal the pieces in a plastic bag before disposal.

Disposing of Bulbs in Bulk

If you're replacing many bulbs at once (switching a whole house to LED), you may have a large quantity of old bulbs to dispose of:

• Collect all old bulbs in a cardboard box lined with newspaper
• For incandescent and halogen: regular trash pickup or a single trip to a glass recycling drop-off
• For CFLs and fluorescent tubes: take to Home Depot, Lowe's, or a hazardous waste collection event — most accept any quantity
• Call ahead for very large quantities (commercial quantities may require a different process)

State-by-State Rules

CFL and fluorescent tube disposal rules vary by state:

• California, Maine, Minnesota, Vermont, Washington: Strict prohibition on CFL/fluorescent disposal in regular trash — recycling required by law
• Most other states: Strongly recommended but not always legally required for households
• Businesses: Commercial generators of fluorescent lamps are subject to stricter regulations in all states — consult your state environmental agency

When in doubt, recycle — it's always the right choice regardless of local rules.

Frequently Asked Questions

Can I put LED bulbs in the regular trash?

Yes — LED bulbs contain no mercury and are not classified as hazardous waste. Wrap them in newspaper or the original packaging before putting in the trash. Recycling is preferred when available — Home Depot and Lowe's accept LEDs at in-store bins.

Where can I recycle CFL bulbs near me?

Home Depot and Lowe's are the most convenient options — they accept CFLs at in-store recycling bins at no charge. You can also find local options at Earth911.com by entering your zip code and searching for "compact fluorescent bulbs."

What happens if I put CFL bulbs in the trash?

In states where it's prohibited, it's technically illegal. More importantly, CFLs in landfills can leach mercury into groundwater over time. The mercury in a single CFL is small, but millions of improperly disposed CFLs add up to a significant environmental problem. Recycling takes 5 minutes and is free at most retailers.

Do I need to do anything special to transport CFLs to a recycling location?

Keep them in their original packaging if possible, or wrap individually in newspaper. Place in a box or bag so they can't roll around and break. If a CFL breaks during transport, seal the pieces in a plastic bag before continuing.
