Cost-Saving Benefits of CFLs and Fluorescent Lamps

CFLs and fluorescent lamps save significant costs in electricity expenses, right? According to recent articles, many people are in doubt about this claim, and refuse to believe these bulbs are actually saving them money by using less energy. Furthermore, the higher initial cost of the bulbs is preventing many consumers from making the switch. However, tests have shown that CFLs can save households money even under the least ideal conditions.

CFLs and fluorescent lamps give off the same amount of light as their traditional incandescent counterparts, but they require considerably less electricity, which in turn reduces the damaging effects electric power generation causes to the environment. Incandescent light bulbs actually require four times the amount of energy to produce equivalent light in a fluorescent lamp. Fluorescent lamps are four to six times more efficient than incandescent lamps, reducing the power demand from local utilities. Because most power stations use coal as a source for electrical generation, they are large emitters of both greenhouse gas and mercury, which is naturally occurring in most coal that is used today.

One Broken Bulb: The Health and Safety Risks

One broken four-foot fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the OSHA mercury exposure eight-hour limit—posing significant health and safety risks to handlers and consumers. Plus, mercury vapor can be emitted for weeks after a single bulb is broken, continually polluting the air in consumers’ homes. When carelessly handled or improperly disposed of, mercury can get into drinking water, lakes, rivers and streams, posing a critical threat to human health, as well as the environment. Recent studies have linked mercury exposure to increased risk of heart attack in men, to mental retardation and neurological disorders in children, and dangerous levels of mercury in the blood of women of childbearing age.

Despite these health concerns, the EPA estimates that approximately 75 to 80 percent of fluorescent lamps are not recycled and are usually placed in dumpsters or trash containers, presenting a considerable risk. One study found that mercury is "strongly and persistently" emitted from dumpsters that contain broken fluorescent lamps.(1) Broken fluorescent lamps need to be properly recycled to prevent the release of mercury vapor. Learn how to clean up a broken bulb or how to safely package and recycle fluorescent lamps by reading our Layers of protection: Packaging used fluorescent lamps post.

Origins of the Phrase “Mad As a Hatter”

Mercury has long been known to be toxic. The phrase "mad as a hatter" refers to the 19th-century occupational disease that resulted from prolonged contact with the mercury used in the manufacture of felt hats. Along with felt hats, mercury has been taken out of many manufacturing processes and products—as the dangers of mercury exposure become more well known.

Most mercury pesticides have been withdrawn from the U.S. market, and many countries banned ocean dumping of mercury and other pollutants in 1972. Production of mercury-containing interior and exterior paints in the United States was phased out in 1991. Mercury, which has been used in medicines for hundreds of years, continues to be used in various folk remedies that can cause mercury exposures. The use of mercury in dental amalgam for tooth fillings has stirred escalating controversy in recent years. Most other medical uses have been banned or are being phased out.

Despite these changes, some workers today, especially laboratory technicians, nurses, and machine operators, continue to be exposed to mercury on the job. Elemental mercury (the silver liquid familiar in thermometers) is a common occupational source of exposure. Fragile fluorescent lamps and compact fluorescent lamps if broken represent another mercury exposure risk as they are handled by manufacturers, transporters, distributors, retailers, consumers and installers, as well as recycling or waste handlers. There are currently no universally enforced packaging standards designed to protect these people. There now exists a proven packaging design with a vapor resistant and zip seal bag that should be mandated to protect people who work with or near fluorescent lamps, as well as for protecting the surrounding environment.

How Do Incandescent Lights Result in More Mercury Pollution Than Fluorescents?

In addition to carefully recycling products that contain mercury, we can reduce mercury pollution by reducing our energy consumption. Because mercury is a byproduct of burning coal, coal-fired power plants are one of the largest sources of mercury pollution. Because incandescent bulbs use several times more electricity over their lifetimes, they require far more power generation and, ultimately, result in more mercury emission than fluorescents. With the coming “maximal achievable technology” clean air standards, it is fully expected that mercury emissions will have to be severely reduced in order to stop this proliferation. Fluorescent lights are four to six times more efficient than incandescent lamps, significantly reducing the power demand from local utilities. The reduced demand for electricity in turn reduces both greenhouse gas and mercury emissions.

Which States Are Raising Awareness of the Dangers of Mercury Vapor?

As fluorescent lamps and CFLs increasingly become businesses and consumers’ primary lighting choice, more states are taking action to address the health and safety issues associated with their use. While fluorescent lamps are considered as a more energy-efficient bulb than traditional incandescent bulbs, these lamps are fragile and, upon breaking, release mercury vapor that can be detrimental to handlers' health—from those involved with handling new bulbs to people involved with storing, packaging and shipping used lamps.

To address the potential dangers of unsafe packaging and transportation of used fluorescent lamps and mercury containing devices, many states are taking a stand to increase awareness by enforcing their own legislation. In March 2010, Washington took the first step in creating a law that requires lights and other mercury-containing devices to be packaged and shipped in material that will minimize the release of mercury into the environment. The law also states that packages should include mercury vapor barrier materials if lamps are transported by the United States postal service or a common carrier or collected via curbside programs and mail-back businesses.

Additional states have addressed this health issue with their own, more specific regulations regarding lamp disposal, including Wisconsin, Minnesota, Massachusetts, California, Vermont, New York, Connecticut, Maine, New Hampshire, Florida and Rhode Island. To read about these laws and find out more information regarding state regulations, read our "Additional State Regulations" post.

EPA Packaging Regulations

Shipping, packaging, and handling of fluorescent lamps is a major concern because of the harmful mercury vapor emitted when the lamps are broken, which commonly occurs during shipment. To lessen the health and environmental risks associated with mercury vapor, national laws--sometimes supplemented by more rigorous state laws--exist to encourage proper recycling of fluorescent lamps. EPA encourages recycling of these lamps by allowing common carrier shipment to recycling facilities. To protect people who handle fluorescent lamps, EPA instructs that packaging should be designed to protect against breakage. While the rules mandate that lamps be packaged in structurally sound packages, the federal laws don't explicitly address mercury vapor release.

EPA Estimates Just 20-25% of Fluorescent Lamps are Recycled

While the new legislation in Washington—addressing the dangers of unsafe packaging and transportation of used fluorescent lamps and mercury-containing devices—shows growth in the right direction, there is still a long way to go in protecting people and the environment from mercury vapor emitted from broken lamps.

The EPA estimates recycling rates of fluorescent lamps at only 20 to 25 percent, leaving the majority to be placed in dumpsters and eventually end up in landfills—where they may emit hazardous mercury vapor into the environment. The consumer recycling rate has been estimated to be even lower—possibly at less than 2 percent.

Mercury-containing waste that isn’t properly recycled poses a serious environmental and health concern. Safe recycling facilities exist, but should be encouraged by new rules and regulations. New legislation should also ensure that used fluorescent lamps are packaged in configurations proven to effectively contain mercury vapor emitted from broken lamps.

Why is it Important to Recycle Used Fluorescent Lamps?

According to EPA estimates, only 20% to 25% of used fluorescent lamps are recycled, These lamps are commonly sent to a recycler in bulk or in pre-paid shipping recycling boxes. The 75% to 80% of fluorescent lamps that are not recycled usually end up in dumpsters or trash containers and, ultimately, in landfills. One study indicates dumpsters that contain broken fluorescent lamps “strongly and persistently” emit mercury.(1) Another study on mercury release from broken fluorescent lamps found that between 17% to 40% of the mercury in broken low-mercury fluorescent lamps is released to the air during the two-week period after breakage.(2) Of this mercury, one-third of the release takes place during the first eight hours following breakage, potentially exposing personnel in the vicinity to unsafe levels of mercury vapor. Using this estimated release rate and an estimated 620 million lamps discarded annually in the United States, broken used fluorescent lamps release approximately two to four tons of mercury each year into the environment.

Used fluorescent lamps need to be properly handled during shipping and recycling. Safe packaging reduces the threat of mercury vapor emitted from broken lamps.

Workplace Lighting

Many businesses strive to keep management expenses low, ensure energy efficiency and provide a safe work environment for employees. When it comes to selecting lighting, all of these aspects must be factored in. Fluorescent lamps have long been the best lighting option for small to large businesses, due to their significant energy savings—providing four to six times higher efficiency than incandescent lights—and long working life. However, these lamps contain hazardous mercury and, from installation to disposal, they must be carefully handled, stored and transported.

While the amount of mercury used in an individual fluorescent bulb has decreased over the past years, one broken four-foot fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the OSHA mercury exposure eight-hour limit—posing a significant occupational health risk. Plus, mercury vapor can be emitted for weeks after a single bulb is broken. In their lifetime, fragile fluorescent lamps are handled by manufacturers, transporters, distributors, retailers, consumers and installers, as well as recycling or waste handlers. Although the lamps could break anywhere down this line and expose workers and the environment to hazardous mercury vapors, there are no universally enforced packaging standards designed to protect these people. Recent legislation has begun to address the issue of safe packaging for fluorescent lamps and other mercury-containing products, and businesses must work to not only comply with these regulations, but also ensure the safety of all personnel in addition to protecting the environment.

What Mercury?

While the amount of mercury used in an individual fluorescent bulb has decreased over the past years, one broken 4-foot fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the OSHA mercury exposure 8-hour limit—posing a significant occupational health risk. Plus, mercury vapor can be emitted for weeks after a single bulb is broken.

In their lifetime, fragile fluorescent lamps are handled by manufacturers, transporters, distributors, retailers, consumers and installers, as well as recycling or waste handlers. Although the lamps could break anywhere down this line and expose workers and the environment to hazardous mercury vapors, there are no universally enforced packaging standards designed to protect these people.

While some steps have been taken to encourage safe recycling and disposal of fluorescent lamps, this fact remains: although a variety of containers are marketed for transportation of fluorescent lamps, many don't provide necessary levels of protection against mercury vapor in the occurrence of breakage. Using a proven packaging design with a vapor resistant lining is vital to ensuring the safety of persons who work with or near fluorescent bulbs, as well as for protecting the surrounding environment, especially as fluorescent lighting continues to grow in popularity and practicality. Currently, only one package design, which includes a vapor resistant and zip seal bag, has proven effective in containing mercury vapor.

Shipping Fluorescent Lamps

A suitable mercury storage or shipping package can effectively contain vapors emitted by broken fluorescent lamps and compact fluorescent lamps (CFLs), but those vapors can reach dangerously high levels inside of the package. A study by NUCON International, Inc. recently tested mercury vapor levels inside and outside containment packaging and found a need for an adsorbent technology that could capture vapor before it escaped from the inside of the package. NUCON broke 40 fluorescent lamps in a mercury-safe containment bag and measured vapor levels outside of the package for leakage, and inside the bag for vapor concentrations. The tests from outside of the packaging showed the vapor was being contained, with only slight leakage that was well within safety limits. However, results from inside the containment bag yielded extremely high and unsafe vapor readings of 150 to 300 times the OSHA 8-hour personal exposure limit (PEL).

It is important to be aware that while mercury vapor can be contained in specific packages, if that package is perforated or opened, vapor levels could be dangerously high inside the bag and seep out. The need for capturing mercury vapor to prevent seepage can be achieved by including an adsorbent technology in the containment packaging. The NUCON study found that a new, patent-pending adsorbent can reduce vapor levels by nearly 60 percent in 15 minutes, and after 12 hours levels are reduced by over 95 percent. Recently announced at the Air & Waste Management Association’s Conference & Exhibition, this adsorbent technology can capture the mercury vapor in the package, protecting users against dangerously high vapor levels resulting from incidental exposure during the accumulation, storage and transportation of lamps. Additionally, a small consumer-size recycling bag, now available, features this technology and allows people to safely store three to four used lamps at home before taking them to a retailer or municipality that accepts CFLs for recycling.

Dangers of Mercury Vapor

Mercury vapor can be detrimental to consumers’ and handlers’ health—from those involved with handling new fluorescent bulbs to people involved with storing, packaging and shipping used and broken lamps. Vapor released from shattered lamps can be contained in specifically designed mercury storage packages, but concentrations inside this packaging can remain dangerously high, creating a risk if the package is opened or perforated. The vapors can be captured within mercury-safe packages with the inclusion of a new, patent-pending adsorbent technology that effectively reduces vapor levels over periods of time.

A Study by NUCON International, Inc., a world-wide leader in providing gas, vapor and liquid phase adsorption solutions, found the adsorbent showed an immediate reduction of mercury vapors by nearly 60 percent after 15 minutes. After 12 hours, the reduction can reach more than 95 percent. This technology, recently announced at the Air & Waste Management Association’s Conference & Exhibition, provides consumers and transporters who come into contact with used CFLs a safe way to handle them. With the vapor contained and captured in safe packaging, consumers’ and handlers’ risks of vapor leaks or seepage are greatly reduced. Also, a small consumer-size recycling bag, available soon, will feature this technology and allow people to safely store three to four used lamps at home before taking them to a retailer or municipality that accepts CFLs for recycling.

Mercury Vapor: Transitioning from Containment to Capture for Safe Fluorescent Lamp Disposal

The popularity of fluorescent lamps and compact fluorescent lamps (CFLs) are steadily growing in the industrial, commercial and residential markets, due to their sustainability, energy efficiency and recent federal legislation banning the manufacture of incandescent light bulbs starting in 2012. Fluorescent lamps and CFLs are four to six times more efficient than incandescent bulbs and emit about the same amount of visible light, all while offering a longer working life and significant savings in energy costs. While there are many positive reasons to employ fluorescent lamps, they can also be potentially dangerous because of their mercury content.

Since exposure to mercury vapor can lead to significant safety and health risks for handlers of fluorescent lamps, it is important to take the necessary precautions when handling, storing or transporting used or broken lamps to protect against any potential harm from released mercury vapor.

Recent efforts to protect consumers and handlers against the inherent dangers of mercury vapor exposure from broken lamps have centered around containing the mercury vapor in the storage and shipping container. However, this traditional method does not protect against vapor exposure if the container is opened or leaks with broken lamps inside. New developments demonstrate a method to actually adsorb and capture the mercury vapor within the container mitigating the risks of vapor exposure.

Read the full white paper here.

The Mercury Debate: Is the CFL Bulb the Right Choice?

The 2007 energy conservation measure passed by Congress set standards to essentially ban incandescent lights by 2013, requiring households to make the switch to more energy efficient lights. However, many consumers are raising the question, whether or not CFLs and fluorescent bulbs are really the more efficient lighting choice. Due to their mercury content, many consumers are wary about placing them in their homes.

However, incandescent bulbs actually result in more mercury pollution than fluorescents. Because mercury is a byproduct of burning coal, coal-fired power plants are one of the largest sources of mercury pollution. Because incandescent bulbs use several times more electricity over their lifetimes, they require far more power generation and, ultimately, result in more mercury emission than fluorescents. With the coming “maximal achievable technology” clean air standards, it is fully expected that mercury emissions will have to be severely reduced in order to stop this proliferation. Fluorescent lights are four to six times more efficient than incandescent lamps, significantly reducing the power demand from local utilities. The reduced demand for electricity in turn reduces both greenhouse gas and mercury emissions.

Furthermore, consumers can safely use energy efficient bulbs if they are properly handled and disposed of when broken or burned out. Learn how to safely clean up a broken bulb or safely package a used bulb to send to a recycling facility.

Layers of Packaging Help Protect Used Fluorescent Lamps

Many customers repurpose the packages fluorescent lamps are sold in—to store used lamps and eventually transport these lamps for disposal or recycling. However, the recent University of Minnesota study I conducted with my team of researchers found that these packages do not contain mercury vapor below permissible workplace exposure levels, as defined by state and federal authorities.

We also tested packaging configurations that enhance this single cardboard layer with a plastic bag, as well as packages that add a second layer of cardboard to the design—with the bags positioned between the two cardboard layers. The latter group contained two package varieties: a double-box with a thicker, tape-sealed plastic bag, and a double box with a foil-plastic laminate bag containing a zip closure. Both of these packages performed better than the other configurations. Yet, only the double box with the foil-plastic laminate bag delivered the necessary levels of protection.

This study indicates that all three layers of the last packaging configuration are critical in the effective containment of mercury vapor. The first cardboard layer provides structure to the configuration and protects contents from outside elements. The bag—which should feature a suitable material and tight seal—contains the mercury vapor, and the inner layer of cardboard prevents broken glass from puncturing the bag and rendering it ineffective.

How To Minimize Health & Safety Risks of Used Fluorescent Lamps: Storage

One broken 48-inch fluorescent lamp in a small room or vehicle can release enough mercury vapor to exceed the Federal Occupational Health and Safety Administration (OSHA) permissible exposure limit (PEL). This means that mercury vapor concentrations could exceed occupational exposure levels when working with or near broken bulbs, especially when multiple bulbs are stored or shipped in bulk to recycling facilities.

Often, maintenance workers at small to large facilities store used lamps for a period of time until numerous lamps are collected for transportation to recycling facilities. Stored lamps may be bumped around and broken, so maintenance workers should package used lamps in a configuration proven to contain mercury vapor emissions. A recent study from the University of Minnesota indicates that three layers of packaging are necessary to provide sufficient containment of mercury vapor. An outer cardboard layer provides structure to the configuration and protects contents from outside elements. A bag positioned between two cardboard layers should feature a suitable material and tight seal—such as a unique zip closure foil-plastic laminate bag—to contain the mercury vapor. Finally, an inner layer of cardboard prevents broken glass from piercing the bag.

How To Minimize Health & Safety Risks of Used Fluorescent Lamps: Handling

Following the proper clean-up and disposal policies is necessary in ensuring the safety of people who handle fluorescent lamps, as well as those in close proximity to them. However, proper disposal of used lamps is not as simple as dropping them in a recycling bin. Lamps must be carefully removed and handled, as well as stored and transported in a package proven to contain mercury vapor. Specific precautions should be taken during each of the following steps: Handling, Storage, Transport, Recycling and Breakage.

Handling:

Mercury vapor—which can get into water, contaminating fish and entering the human food chain—can cause neurological damage to adults, children and fetuses. To avoid these issues, lamps should be carefully installed and uninstalled by maintenance professionals. Anyone handling a fluorescent bulb should take caution, as these lamps are fragile and can shatter easily.

What Happens When the Bulb Breaks?

When a fluorescent lamp breaks, it emits mercury vapor, which can cause severe health and safety risks. Mercury vapor, which can be absorbed through the skin or inhaled, can cause neurological damage to adults, children and fetuses. It is considered a persistent bioaccumulative toxic chemical, since it doesn't degrade in the environment. When mercury vapor gets into water, it is converted to methyl mercury and can enter the food chain through fish.

To avoid both health and environmental risks associated with mercury vapor emissions from broken fluorescent lamps, they should be packaged, stored and transported to recycling facilities in a configuration that is specifically designed to contain mercury vapor—and proven to be effective. To learn more about this configuration, read our Layers of protection: Packaging used fluorescent lamps post.

The First Waste Container

Universal waste containers that could be transported by common carrier were first introduced in 1998. The first containers were primarily used to ship fluorescent lighting. Initially, these containers were simple corrugated boxes, with some including a plastic bag inside the box. Since the contents were made of glass, they were designed primarily to contain the contents within the shipping container. However, since mercury begins to vaporize at 70 degrees F, packaging improvements were needed to address the issue of potential mercury vapor release in the event of breakage during accumulation and transport. Read more about packaging designed to contain mercury vapor.
