Fluorescent lamp crusher

Last updated

A fluorescent lamp crusher is a device that crushes and stores spent fluorescent lamps prior to processing at a recycling facility, while controlling the release of mercury vapor emissions. [1] Also known as drum-top crushing, this lamp disposal method is designed to reduce the storage, labor, and shipping costs of recycling lamps over other methods, as well as decrease the likelihood of mercury release during transport to a recycling facility. [2] Fluorescent lamp crushers are designed for use primarily in commercial and institutional facility management contexts. [3]

Operation

A fluorescent lamp crusher consists of a vacuum-sealed container, often a 55-gallon steel drum, in which glass fragments collect after passing through an entry tube and crushing mechanism. The mercury content of the lamp is contained by the vacuum and trapped in a filter arrangement, which must be replaced periodically. Spent fluorescent lamps are typically hand-fed into the entry tube, rapidly drawn into the drum by the vacuum seal and crushed in the motorized crushing assembly. Once the storage container is full, it is replaced and shipped to a recycling facility for processing. [4] Several companies manufacture fluorescent lamp crushers, including Dextrite, Air Cycle Corporation, and Resource Technologies. [5]

Regulations

Drum-top lamp crushing is regulated at the state level in the United States. State regulations must adhere to mercury emission standards developed by the U.S. Environmental Protection Agency. [6] Some states prohibit crushing except by permit in belief that lamp crushers emit levels of mercury vapor higher than those established by the U.S. EPA. [7] However, most states allow lamp crushing as treatment of either hazardous or universal waste. [8]

Hazardous waste is waste that must be handled properly to avoid damaging human health or the environment. Waste can be hazardous because it is toxic, reacts violently with other chemicals, or is corrosive, among other traits. As of 2022, humanity produces 300-500 million metric tons of hazardous waste annually. Some common examples are electronics, batteries, and paints. An important aspect of managing hazardous waste is safe disposal. Hazardous waste can be stored in hazardous waste landfills, burned, or recycled into something new. Managing hazardous waste is important to achieve worldwide sustainability. Hazardous waste is regulated on national scale by national governments as well as on an international scale by the United Nations (UN) and international treaties.

<span class="mw-page-title-main">Fluorescent lamp</span> Lamp using fluorescence to produce light

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp, but is less efficient than most LED lamps. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficiency of an incandescent bulb may only be 16 lumens per watt.

<span class="mw-page-title-main">Chemical waste</span> Waste made from harmful chemicals

Chemical waste is any excess, unused, or unwanted chemical. Chemical waste may be classified as hazardous waste, non-hazardous waste, universal waste, or household hazardous waste, each of which is regulated separately by national governments and the United Nations. Hazardous waste is material that displays one or more of the following four characteristics: ignitability, corrosivity, reactivity, and toxicity. This information, along with chemical disposal requirements, is typically available on a chemical's Safety Data Sheet (SDS). Radioactive and biohazardous wastes require additional or different methods of handling and disposal, and are often regulated differently than standard hazardous wastes.

A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.

Municipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog. Although the waste may originate from a number of sources that has nothing to do with a municipality, the traditional role of municipalities in collecting and managing these kinds of waste have produced the particular etymology 'municipal.'

<span class="mw-page-title-main">Construction waste</span> Unwanted material produced directly or incidentally by the construction industries

Construction waste or debris is any kind of debris from the construction process. Different government agencies have clear definitions. For example, the United States Environmental Protection Agency EPA defines construction and demolition materials as “debris generated during the construction, renovation and demolition of buildings, roads, and bridges.” Additionally, the EPA has categorized Construction and Demolition (C&D) waste into three categories: non-dangerous, hazardous, and semi-hazardous.

There is no national law in the United States that mandates recycling. State and local governments often introduce their own recycling requirements. In 2014, the recycling/composting rate for municipal solid waste in the U.S. was 34.6%. A number of U.S. states, including California, Connecticut, Delaware, Hawaii, Iowa, Maine, Massachusetts, Michigan, New York, Oregon, and Vermont have passed laws that establish deposits or refund values on beverage containers while other jurisdictions rely on recycling goals or landfill bans of recyclable materials.

<span class="mw-page-title-main">Battery recycling</span> Process

Battery recycling is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. Batteries contain a number of heavy metals and toxic chemicals and disposing of them by the same process as regular household waste has raised concerns over soil contamination and water pollution. While reducing the amount of pollutants being released through disposal through the uses of landfill and incineration, battery recycling can facilitate the release of harmful materials from batteries to both the environment and the workers recycling batteries.

<span class="mw-page-title-main">Household hazardous waste</span>

Household hazardous waste (HHW) was a term coined by Dave Galvin from Seattle, Washington in 1982 as part of the fulfillment of a US EPA grant. This new term was reflective of the recent passage of the Resource Conservation and Recovery Act of 1976 in the US. This act and subsequent regulations strengthened the environmental protection requirements for landfills, in Subpart D, and created a "cradle to grave" management system for hazardous wastes, in Subpart C. From RCRA 1976 the US EPA promulgated rules in 1980 which explicitly excluded any wastes from household origins from regulation as a hazardous waste at the federal level. Most US states adopted parallel regulations to RCRA 1976 but were allowed to be more stringent. California took advantage of this allowance and chose to not exempt household origin wastes from their state hazardous waste laws. HHW products exhibit many of the same dangerous characteristics as fully regulated hazardous waste which are their potential for reactivity, ignitability, corrosivity, toxicity, or persistence. Examples include drain cleaners, oil paint, motor oil, antifreeze, fuel, poisons, pesticides, herbicides and rodenticides, fluorescent lamps, lamp ballasts containing PCBs, some smoke detectors, and in some states, consumer electronics. Except for California, most states exclude HHW from their hazardous waste regulations and regulate the management of HHW largely under their solid waste regulatory schemes.

Biomedical waste or hospital waste is any kind of waste containing infectious materials generated during the treatment of humans or animals as well as during research involving biologics. It may also include waste associated with the generation of biomedical waste that visually appears to be of medical or laboratory origin, as well research laboratory waste containing biomolecules or organisms that are mainly restricted from environmental release. As detailed below, discarded sharps are considered biomedical waste whether they are contaminated or not, due to the possibility of being contaminated with blood and their propensity to cause injury when not properly contained and disposed. Biomedical waste is a type of biowaste.

The California Department of Resources Recycling and Recovery is a branch of the California Environmental Protection Agency that oversees the state's waste management, recycling, and waste reduction programs. CalRecycle was established in 2010 to replace the California Integrated Waste Management Board. It is known for administering the California Redemption Value (CRV) program, among other responsibilities.

<span class="mw-page-title-main">Waste</span> Unwanted or unusable materials

Waste are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero.

Solid waste policy in the United States is aimed at developing and implementing proper mechanisms to effectively manage solid waste. For solid waste policy to be effective, inputs should come from stakeholders, including citizens, businesses, community-based organizations, non-governmental organizations, government agencies, universities, and other research organizations. These inputs form the basis of policy frameworks that influence solid waste management decisions. In the United States, the Environmental Protection Agency (EPA) regulates household, industrial, manufacturing, and commercial solid and hazardous wastes under the 1976 Resource Conservation and Recovery Act (RCRA). Effective solid waste management is a cooperative effort involving federal, state, regional, and local entities. Thus, the RCRA's Solid Waste program section D encourages the environmental departments of each state to develop comprehensive plans to manage nonhazardous industrial and municipal solid waste.
