Disposal of Lamps Containing Mercury
Mercury-added bulbs manufactured after November 30, 2003
will bear a label, which states, "Contains Mercury," or it will have the symbol "Hg" within a circle on the lamp (Hg is
the scientific symbol for mercury on the periodic table of elements). This signifies that the bulb contains mercury. Any mercury-containing
bulb, regardless of the amount of mercury, cannot be discarded in the trash. Bulbs containing mercury should
be handled as hazardous ("universal") waste, stored carefully prior to disposal to avoid breakage, and
properly disposed. Although fluorescent and HID bulbs contain mercury, they are more energy efficient than incandescent or halogen bulbs (for
more information on energy efficient lighting, visit Efficiency Vermont).
By requiring less energy, these bulbs reduce the amount of pollution from energy production, which includes the emission of mercury (from
coal combustion). The information provided below will:
Identifying Bulbs that Contain Mercury
The following types of bulbs contain mercury:
- Fluorescent, compact fluorescent, black lights.
- High intensity discharge bulbs (HID). These bulbs are commonly used in security, outdoor and warehouse lighting. HID lighting is becoming
popular for indoor use in commercial settings. The following are HID bulbs:
- mercury vapor
- metal halide
- high pressure sodium
- HID lighting is also used in vehicle headlamps. HID headlamps can be identified by their characteristic bluish-white tint when lit. Some
halogen bulb manufacturers are now applying a blue coating to their bulbs which makes them look like HID bulbs when lit, however, halogen
bulbs do not contain mercury (click here for more information on mercury use in automobiles).
- Ultraviolet bulbs
- Neon bulbs
For information on Mercury Use in Lightbulbs see:
There are no non-mercury fluorescent or HID bulbs available at this time. Green tip or low-mercury fluorescent lighting contains less mercury,
but still cannot be placed in the trash. For more information on energy efficient, non-mercury lighting, such as LEDs, please visit Efficiency Vermont's web site: www.efficiencyvermont.com.
Any mercury-containing bulb, regardless of the amount of mercury, should not be discarded in the trash and should be handled as a hazardous
("universal") waste and stored carefully to avoid breakage. Labeled mercury-containing products are banned
from landfills. Disposal options differ depending on whether the bulbs are from household use or business or other non-household use.
Mercury-containing bulbs cannot be placed in the regular trash. Many retailers of lighting products such as hardware stores, supermarkets, home improvement centers, and lighting stores offer recycling of fluorescent bulbs. Any number of CFLs will be accepted and there is a limit of ten or fewer of other bulbs (such as lineal tubes) per visit. So bring
in your burned-out fluorescent and other mercury-containing bulbs
today to a retail collection location.
If you don’t have a participating retailer in your area or if you have larger quantities of non-CFL bulbs, check with your local municipality or solid waste district for recycling options.
Small businesses may be able to dispose of smaller quantities of spent bulbs at retail collection locations or check with your local municipality or solid waste district for recycling options.
Small businesses may be able to dispose of spent bulbs at town
or solid waste district collection events. Businesses who handle
larger volumes of bulbs from change-outs or retrofits can contact
a local electrical wholesaler who offers
bulb recycling to their customers or contact a commercial
lamp recycler (a business that collects and recycles mercury,
glass and metal components) for disposal. If it is not possible
to use any of the previous disposal options, bulbs should be disposed
of through a licensed hazardous waste transporter. Additional information
is available in the Lamp Fact
Bulb Storage and Handling
- Store bulbs in an area and in a way that will prevent them from breaking, such as in boxes the bulbs came in or in boxes supplied by a
- Do not break or crush bulbs because mercury may be released.
If a bulb is accidentally broken, see Lamp
Fact Sheet for bulb breakage clean-up procedure.
