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.

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." 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.

Study Results Indicate the Need for Safer Packaging, Storage and Transportation of Used Fluorescent Lamps

Results of a recent study conducted by a research team at the University of Minnesota School of Public Health, Division of Environmental Health Sciences suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against mercury vapors emitted from broken lamps.

The study, published in the March 2009 issue of the Journal of the Air & Waste Management Association, found that of the five packages tested in the study, just one configuration—consisting of a zip-closure plastic-foil laminate bag layered between two cardboard boxes—minimized exposure levels below acceptable occupational limits, as defined by state and federal regulations and guidelines.

Based on the measurements of mercury vapor from single broken fluorescent bulbs, it was determined the need for additional research to quantify emissions from various types of packaging. The results indicate that emissions from packages not designed to contain mercury vapor represent a real health and safety concern.

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.

Where do Fluorescent Lamps Go After They are Recycled?

Recycled lamps are sent to a recycling facility via truck, UPS or FedEx® in bulk or in pre-paid shipping recycling boxes, such as the Waste Management® LampTracker® system, which is specifically designed to accommodate various sized lamps and effectively contain mercury vapor emitted from broken lamps.

Once received, the recycler crushes the lamps, along with other contaminated products, devices and debris, to safely exhaust the mercury vapor and extract and reuse the resultant mercury—ensuring mercury is not released into the environment. The remaining debris is then placed in 55-gallon drums and sent to a retort facility—where the drums are heated to high temperatures to eliminate any remaining mercury. Any remaining glass and aluminum is furthered recycled and reused.

This process reduces the potential dangers of mercury vapor emitted from used fluorescent lamps—effectively reducing environmental liability and protecting both handlers and consumers from potential safety hazards and health risks.

How Many Fluorescent Lamps are Recycled?

According to the EPA, recycling rates of fluorescent lamps are estimated 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. However, taking waste to a recycling center may not always be the most efficient solution. Consumers can use a recycling box to ship bulbs instead. If consumers choose this option, it is important to select a packaging configuration that effectively contains mercury vapor. A recent study conducted by the University of Minnesota tested the effectiveness of various packages in containing mercury vapor emitted from broken fluorescent lamps. The study found that many packages do not sufficiently contain mercury vapor, such as single-layer cardboard boxes (representing the original manufacturer’s box or container) as well as single layer boxes with a sealed plastic bag. Just one configuration—consisting of a zip-closure plastic-foil laminate bag layered between two cardboard boxes—minimized exposure levels below acceptable occupational limits, as defined by state and federal regulations and guidelines.

Fluorescent Lamp and CFL Disposal

Disposing of mercury-containing products, including fluorescent lamps and CFLs, is an important issue. It is important for consumers to realize that CFLs and fluorescent bulbs require special handling and disposal. Like all mercury-containing fluorescent lights, CFLs should be properly stored, transported and recycled to prevent these fragile bulbs from breaking and emitting hazardous mercury vapor. They cannot be thrown away in the trash, but should be taken to a recycling center or disposed of by using a proven recycling box.

However, taking them to a recycling center may not always be the most efficient solution. Consumers can use a recycling box to ship bulbs instead. If consumers choose this option, it is important to select a packaging configuration that effectively contains mercury vapor. A recent study conducted by the University of Minnesota tested the effectiveness of various packages in containing mercury vapor emitted from broken fluorescent lamps.

Fluorescent Lamp Recycling – Not a Common Act for Consumers

With incandescent lamps out and energy-efficient fluorescent lamps and CFLs in, it is important for consumers to understand all factors of using them; from the initial purchase to proper disposal procedures. Fluorescent lamps and CFLs are a more sustainable lighting option, providing four to six times more efficiency than their incandescent counterparts and emitting about the same amount of visible light, all while offering longer working life and saving significant energy costs. Although incandescent light bulbs may seem like the cheaper option at the counter, consumers will actually save money on CFLs in the long run since they last an estimated 8 to 15 times as long as an incandescent.

When it comes to proper disposal, we are falling short. 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. The consumer recycling rate has been estimated to be even lower—possibly at less than 2 percent. Due to their mercury content, this is a serious concern for the health of not only our environment but also for ourselves.
