Minimize Safety, Health and Environmental Risks of Used Fluorescent Lamps: Transport

Fluorescent lamps release an estimated one ton of mercury into the air each year in the US alone, and transportation of used lamps may be a significant source of emissions. According to estimates derived from modeling, four percent of mercury air emissions from all products were from fluorescent lamps in 2005—with higher mercury emissions taking place during waste lamp transport than during disposal processes. (1) Measurements of mercury emissions from dumpsters and from transfer station activities support the evidence that transportation of used lamps results in significant mercury vapor emissions. (2)

According to these findings, many used lamps are broken en route to recycling facilities, negating environmental efforts before the lamps even arrive at their final destination. To prevent the release of mercury vapor during the often-rough treks to recycling facilities, lamps should also be transported in packages proven to contain mercury vapor.

Lighting the Workplace with Fluorescent Bulbs

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.

CFL Recycling Information Supplied by Manufacturers: Philips, TESCO and GE

Although consumer awareness of the health and safety risks associated with mercury vapor emitted from broken CFLs has increased, the Environmental Protection Agency (EPA) estimates recycling rates of possibly less than two percent. If not properly recycled, the emitted mercury vapor poses a significant threat to not only the health of consumers, but also to the health of our environment. Mercury-containing products, such as CFLs, need to be properly recycled to truly be considered truly green products. Yet according to a study conducted by Toxic Waste Facts (1), only one of the three top light bulb manufacturers displays significant recycling information on their packaging:

Philips: The packaging of a CFL from Philips contains no specific information on disposal or risks associated with mercury contained in the bulbs. The information on the packaging details the life expectancy, wattage, a recycling symbol and an A rating.

TESCO: The packaging of a CFL from TESCO includes handling and fitting safety instructions, as well as a list of states that ban CFL household waste disposal, with more information available in store or via the website recycle-more.co.uk. Packages also contain the A rating and the crossed-out wheeled bin symbol. However, they do not offer any instructions regarding breakage clean-up or health risks.

General Electric: The packaging of a CFL from General Electric contains no information on disposal, recycling or any risks associated with the bulb. The information on the packaging details the life expectancy, wattage and an A rating.

It is important that consumers are made aware of the risks associated with broken CFLs and other mercury-containing products, and manufacturers should change packaging to better detail risks, usage and disposal methods.

The End of an Era: Incandescent Light Bulb Factories Closing

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. According to recent news, the last major General Electric factory in the United States is closing this month, marking an end to a fixture that has been lighting homes since the 1870s. With incandescents out, fluorescent lamps and CFLs continue to grow in popularity, providing energy and greenhouse gas emission savings.

Many consumers are worried about the mercury levels contained in fluorescent lights and the potential health, safety and environmental issues caused by mercury vapor emitted from broken lamps. However, with proper storage, transportation and disposal, fluorescent lights can be a green and safe lighting solution. According to a recent study by the University of Minnesota, only one package design out of the five tested is effective in containing mercury vapor beyond permissible exposure levels. Find out more about this configuration, which includes a vapor resistant and zip seal bag.

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.

Part II: Analyzing the Environmental Impact of Different Waste Management Methods: Incineration and Crushing

Incineration is a waste treatment technology that involves the combustion of organic materials or substances.(1) Also known as "thermal treatment", incineration of waste materials converts the waste into incinerator bottom ash, flue gases, particulates and heat. In the past, many municipal waste combustors did not have special controls to reduce mercury emissions. The incineration of mercury-containing lamps, therefore, released up to 90% of the mercury to the air.(2) By the end of 2000, most incinerators were equipped with more stringent EPA-mandated mercury controls, dramatically reducing the amount of mercury that incinerators release from any mercury-containing product. According to the EPA, mercury emissions from municipal solid waste combustors declined from 42 tons of mercury in 1990 to 2 tons in 2001.(3) However, this amount of mercury release can be further reduced by recycling used fluorescent lamps.

Crushing lamps prior to transportation reduces the volume of waste, while utilizing mercury filters and other technology to limit mercury emissions. Crushing can significantly reduce transportation and storage costs for generators. However, the efficacy of lamp crushers is debated, and the practice has been banned by many state pollution control agencies.

Other recycling options, such as the services offered by Mercury Waste Solutions, should be applied to mercury-containing lamps to safely and effectively remove the mercury vapor. Their patented continuous flow retort oven has been designed to process up to 1,000 lbs per hour of flowable mercury-contaminated powders and other solids—effectively recovering mercury from contaminated products and reducing mercury pollution.

Part I: Analyzing the Environmental Impact of Different Waste Management Methods: Recycling Vs. Landfills

Recycling mercury-containing lights, such as fluorescent lamps and CFLs, provides many health, safety and environmental advantages. The main advantage of recycling used energy-efficient lights is in preventing mercury from entering the solid waste steam—where a portion of it is likely to be released into the environment. Another advantage is from the reuse of certain raw materials from mercury-containing lamps, including the mercury itself. Although the initial cost for recycling is higher than disposal to landfills, the cost is typically less than 1% of the electric savings allotted from the reduced energy use fluorescent lamps provide over traditional incandescent lights.(1)

Many consumers dispose of used fluorescent lamps in dumpsters, which eventually end up in landfills, where they may emit hazardous mercury vapor into the environment. A study of exposure to broken low-mercury lamps by the New Jersey Department of Environmental Protection entitled, "Release of Mercury from Broken Fluorescent Bulbs" demonstrated that "elevated airborne levels of mercury could exist in the vicinity of recently broken lamps, and "could exceed occupational exposure limits."(2) Collectively, the total amount of mercury released from lamp breakage adds to the overall mercury pollution in the United States, increasing health and safety hazards for consumers and waste handlers. Increased lamp recycling is recommended to further reduce mercury pollution.

What is the Lighting Industry Doing to Reduce Mercury Use?

The lighting industry has slowly reduced the amount of mercury used in fluorescent lamps over the past 20 years and, according to NEMA surveys, mercury use has been reduced dramatically over the last 7 years.(1) Since 1990, NEMA has conducted a number of surveys, which indicate the total amount of mercury contained in all lamps in the U.S. declined to 17 tons in 1994, 13 tons in 1999, 9 tons in 2001 and 7 tons in 2003—nearly a 90% reduction from previous years.(2) According to this trend, researchers believe this number will continue to decline in future years.

The lighting industry accomplished these dramatic reductions by collectively investing millions of dollars in new lamp manufacturing equipment and processes. However, fluorescent lamps must still be handled, stored and transported to recycling facilities with care. To ensure the safety of people who handle these lamps and the environment, there is a need for better regulations for packaging that controls the release of mercury vapor emitted from broken lamps.

Why Do Fluorescent Lamps Need Mercury?

Mercury is an essential component of energy-efficient fluorescent lamps, allowing them to produce light and provide a longer life in comparison to incandescent bulbs. A typical fluorescent lamp is composed of a phosphor coated glass tube with electrodes located at either end. The tube contains mercury, of which only a very small amount is in vapor form. When a voltage is applied, the electrodes energize the mercury vapor, causing it to emit ultraviolet (UV) energy. The phosphor coating absorbs the UV energy, causing the phosphor to fluoresce and emit visible light.(1)

The amount of mercury required is very small, typically measured in milligrams, and varies by lamp type, year of manufacture, manufacturing plant and manufacturer. Although it is a necessary component, mercury from fluorescent lamps still poses significant health and environmental issues, and lamps should be properly stored, transported and recycled in a packaging configuration proven to effectively contain mercury vapor.

CFL Usage and What You Should Do If a CFL Breaks in Your Home

As a result of a growing green movement and new government regulations—including an Act of Congress to cease the manufacture of incandescent lamps by 2013—the use of more energy efficient lights, such as CFLs, continues to increase. Like all fluorescent lights, CFLs contain hazardous mercury vapor, which is emitted when these fragile bulbs break and causes significant health and safety issues, as well as environmental concerns.

What should you do if a CFL breaks in your home? A Maine Compact Fluorescent Lamp Breakage Study found that mercury concentration in a room can exceed permissible exposure levels, even from the breakage of a single CFL.

The need for more stringent packaging regulations

The Environmental Protection Agency (EPA) is one of the organizations challenged with the task of simultaneously encouraging the use of energy-efficient fluorescent lamps, while also protecting the environment and people from harmful mercury vapor. The EPA permits common carrier shipment to recycling facilities, and the federal Universal Waste Rule requires packaging to be compatible with the contents of lamps, structurally sound and adequate to prevent breakage—but this rule does not specifically address mercury vapor release.

In 2005, a provision was added that requires packaging for mercury-containing products to be "reasonably designed to prevent the escape of mercury into the environment by volatilization or any other means." However, fluorescent lamps were excluded from this rule.

This may change. More recent federal regulations applicable to other mercury wastes (like switches, thermostats and thermometers) require management in packaging designed to prevent the loss of mercury vapor. Plus, a new law in the State of Washington requires that many lamps be managed in containers that prevent the loss of mercury vapors, and the State of Wisconsin recently considered language that would require mercury vapor containment for household lamps. Read more about new state legislation in my next post.
