Electronic waste, e-waste, e-scrap, or Waste Electrical and Electronic Equipment (WEEE)
describes discarded electrical or electronic devices. There is a lack of consensus as to whether
the term should apply to resale, reuse, and refurbishing industries, or only to product that cannot
be used for its intended purpose. Informal processing of electronic waste in developing countries
may cause serious health and pollution problems, though these countries are also most likely to
reuse and repair electronics. Some electronic scrap components, such as CRTs, may contain
contaminants such as lead, cadmium, beryllium, or brominated flame retardants. Even in
developed countries recycling and disposal of e-waste may involve significant risk to workers
and communities and great care must be taken to avoid unsafe exposure in recycling operations
and leaching of material such as heavy metals from landfills and incinerator ashes. Scrap
industry and USA EPA officials agree that materials should be managed with caution, but many
believe that environmental dangers of used electronics have been exaggerated.

     Problems
     Rapid changes in technology, changes in media (tapes, software, MP3), falling prices, and
     planned obsolescence have resulted in a fast-growing surplus of electronic waste around
     the globe. Dave Kruch, CEO of Cash For Laptops, regards electronic waste as a "rapidly
     expanding" issue. Technical solutions are available, but in most cases a legal framework, a
     collection system, logistics, and other services need to be implemented before a technical
     solution can be applied. Display units (CRT, LCD, LED monitors), Processors (CPU
     chips, RAM), and audio components have different useful lives. Processors are most
     frequently outdated (by software) and are more likely to become "e-waste", while display
     units are most often replaced while working without repair attempts, due to changes in
     wealthy nation appetites for new display technology.

     An estimated 50 million tons of E-waste are produced each year[]. The USA discards 30
     million computers each year and 100 million phones are disposed of in Europe each year.
     The Environmental Protection Agency estimates that only 15-20% of e-waste is recycled,
     the rest of these electronics go directly into landfills and incinerators."EPA estimates for
     2006-7"..

     According to a report by UNEP titled, "Recycling - from E-Waste to Resources," the
     amount of e-waste being produced - including mobile phones and computers - could rise
     by as much as 500 percent over the next decade in some countries, such as India. The
     United States is the world leader in producing electronic waste, tossing away about 3
     million tons each year. China already produces about 2.3 million tons (2010 estimate)
     domestically, second only to the United States. And, despite having banned e-waste
     imports, China remains a major e-waste dumping ground for developed countries.

     Electrical waste contains hazardous but also valuable and scarce materials. Up to 60
     elements can be found in complex electronics.

     In the United States, an estimated 70% of heavy metals in landfills comes from discarded
     electronics.
While there is agreement that the number of discarded electronic devices is increasing,
there is considerable disagreement about the relative risk (compared to automobile scrap,
for example), and strong disagreement whether curtailing trade in used electronics will
improve conditions, or make them worse. According to an article in Motherboard,
attempts to restrict the trade have driven reputable companies out of the supply chain, with
unintended consequences.

Global trade issues


One theory is that increased regulation of electronic waste and concern over the
environmental harm in mature economies creates an economic disincentive to remove
residues prior to export. Critics of trade in used electronics maintain that it is too easy for
brokers calling themselves recyclers to export unscreened electronic waste to developing
countries, such as China, India and parts of Africa, thus avoiding the expense of removing
items like bad cathode ray tubes (the processing of which is expensive and difficult). The
developing countries are becoming big dump yards of e-waste. Proponents of international
trade point to the success of fair trade programs in other industries, where cooperation has
led creation of sustainable jobs, and can bring affordable technology in countries where
repair and reuse rates are higher.

Defenders of the trade in used electronics say that extraction of metals from virgin mining
has also been shifted to developing countries. Hard-rock mining of copper, silver, gold
and other materials extracted from electronics is considered far more environmentally
damaging than the recycling of those materials. They also state that repair and reuse of
computers and televisions has become a "lost art" in wealthier nations, and that
refurbishing has traditionally been a path to development. South Korea, Taiwan, and
southern China all excelled in finding "retained value" in used goods, and in some cases
have set up billion-dollar industries in refurbishing used ink cartridges, single-use
cameras, and working CRTs. Refurbishing has traditionally been a threat to established
manufacturing, and simple protectionism explains some criticism of the trade. Works like
"The Waste Makers" by Vance Packard explain some of the criticism of exports of
working product, for example the ban on import of tested working Pentium 4 laptops to
China, or the bans on export of used surplus working electronics by Japan.

Opponents of surplus electronics exports argue that lower environmental and labor
standards, cheap labor, and the relatively high value of recovered raw materials leads to a
transfer of pollution-generating activities, such as burning of copper wire. In China,
Malaysia, India, Kenya, and various African countries, electronic waste is being sent to
these countries for processing, sometimes illegally. Many surplus laptops are routed to
developing nations as "dumping grounds for e-waste". Because the United States has not
ratified the Basel Convention or its Ban Amendment, and has no domestic laws forbidding
the export of toxic waste, the Basel Action Network estimates that about 80% of the
electronic waste directed to recycling in the U.S. does not get recycled there at all, but is
put on container ships and sent to countries such as China. This figure is disputed as an
exaggeration by the EPA, the Institute of Scrap Recycling Industries, and the World
    Reuse, Repair and Recycling Association. Independent research by Arizona State
    University showed that 87-88% of imported used computers did not have a higher value
    than the best value of the constituent materials they contained, and that "the official trade
    in end-of-life computers is thus driven by reuse as opposed to recycling".

    Guiyu in the Shantou region of China, Delhi and Bangalore in India as well as the
    Agbogbloshie site near Accra, Ghana have electronic waste processing areas.
    Uncontrolled burning, disassembly, and disposal causes a variety of environmental
    problems such as groundwater contamination, atmospheric pollution, or even water
    pollution either by immediate discharge or due to surface runoff (especially near coastal
    areas), as well as health problems including occupational safety and health effects among
    those directly and indirectly involved, due to the methods of processing the waste.
    Thousands of men, women, and children are employed in highly polluting, primitive
    recycling technologies, extracting the metals, toners, and plastics from computers and
    other electronic waste. Recent studies show that 7 out of 10 children in this region have
    too much lead in their blood. Proponents of the trade say growth of internet access is a
    stronger correlation to trade than poverty. Haiti is poor and closer to the port of New York
    than southeast Asia, but far more electronic waste is exported from New York to Asia
    than to Haiti. Thousands of men, women, and children are employed in reuse,
    refurbishing, repair, and remanufacturing, unsustainable industries in decline in developed
    countries. Denying developing nations access to used electronics may deny them
    sustainable employment, affordable products, and internet access, or force them to deal
    with even less scrupulous suppliers. In a series of seven articles for The Atlantic,
    Shanghai-based reporter Adam Minter describes many of these computer repair and scrap
    separation activities as objectively sustainable.

    Opponents of the trade argue that developing countries utilize methods that are more
    harmful and more wasteful. An expedient and prevalent method is simply to toss
    equipment onto an open fire, in order to melt plastics and to burn away unvaluable metals.
    This releases carcinogens and neurotoxins into the air, contributing to an acrid, lingering
    smog. These noxious fumes include dioxins and furans. Bonfire refuse can be disposed of
    quickly into drainage ditches or waterways feeding the ocean or local water supplies.

    In June 2008, a container of electronic waste, destined from the Port of Oakland in the
    U.S. to Sanshui District in mainland China, was intercepted in Hong Kong by
    Greenpeace.Concern over exports of electronic waste were raised in press reports in India,
    Ghana, Ivory Coastand Nigeria.



Ewaste management

Recycling
Today the electronic waste recycling business is in all areas of the developed world a large and
rapidly consolidating business. Part of this evolution has involved greater diversion of electronic
waste from energy-intensive downcycling processes (e.g., conventional recycling), where
equipment is reverted to a raw material form. This diversion is achieved through reuse and
refurbishing. The environmental and social benefits of reuse include diminished demand for new
products and virgin raw materials (with their own environmental issues); larger quantities of pure
water and electricity for associated manufacturing; less packaging per unit; availability of
technology to wider swaths of society due to greater affordability of products; and diminished
use of landfills.

Audiovisual components, televisions, VCRs, stereo equipment, mobile phones, other handheld
devices, and computer components contain valuable elements and substances suitable for
reclamation, including lead, copper, and gold.

One of the major challenges is recycling the printed circuit boards from the electronic wastes.
The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base
metals as copper, iron, aluminum, etc. Conventional method employed is mechanical shredding
and separation but the recycling efficiency is low. Alternative methods such as cryogenic
decomposition have been studied for printed circuit board recycling, and some other methods are
still under investigation.

n developed countries, electronic waste processing usually first involves dismantling the
equipment into various parts (metal frames, power supplies, circuit boards, plastics), often by
hand, but increasingly by automated shredding equipment. A typical example is the NADIN
electronic waste processing plant in Novi Iskar, Bulgaria -- the largest facility of its kind in
Eastern Europe. The advantages of this process are the human's ability to recognize and save
working and repairable parts, including chips, transistors, RAM, etc. The disadvantage is that the
labor is cheapest in countries with the lowest health and safety standards.

In an alternative bulk system, a hopper conveys material for shredding into an unsophisticated
mechanical separator, with screening and granulating machines to separate constituent metal and
plastic fractions, which are sold to smelters or plastics recyclers. Such recycling machinery is
enclosed and employs a dust collection system. Some of the emissions are caught by scrubbers
and screens. Magnets, eddy currents, and trommel screens are employed to separate glass,
plastic, and ferrous and nonferrous metals, which can then be further separated at a smelter.
Leaded glass from CRTs is reused in car batteries, ammunition, and lead wheel weights, or sold
to foundries as a fluxing agent in processing raw lead ore. Copper, gold, palladium, silver and tin
are valuable metals sold to smelters for recycling. Hazardous smoke and gases are captured,
contained and treated to mitigate environmental threat. These methods allow for safe reclamation
of all valuable computer construction materials. Hewlett-Packard product recycling solutions
manager Renee St. Denis describes its process as: "We move them through giant shredders about
30 feet tall and it shreds everything into pieces about the size of a quarter. Once your disk drive
is shredded into pieces about this big, it's hard to get the data off".

An ideal electronic waste recycling plant combines dismantling for component recovery with
increased cost-effective processing of bulk electronic waste.
Reuse is an alternative option to recycling because it extends the lifespan of a device. Devices
still need eventual recycling, but by allowing others to purchase used electronics, recycling can
be postponed and value gained from device use.

Benefits of recycling

Recycling raw materials from end-of-life electronics is the most effective solution to the growing
e-waste problem. Most electronic devices contain a variety of materials, including metals that
can be recovered for future uses. By dismantling and providing reuse possibilities, intact natural
resources are conserved and air and water pollution caused by hazardous disposal is avoided.
Additionally, recycling reduces the amount of greenhouse gas emissions caused by the
manufacturing of new products. It simply makes good sense and is efficient to recycle and to do
our part to keep the environment green.

Electronic waste substances




Several sizes of button and coin cell with 2 9v batteries as a size comparison. They are all
recycled in many countries since they contain lead, mercury and cadmium.

Some computer components can be reused in assembling new computer products, while others
are reduced to metals that can be reused in applications as varied as construction, flatware, and
jewelry.

Substances found in large quantities include epoxy resins, fiberglass, PCBs, PVC (polyvinyl
chlorides), thermosetting plastics, lead, tin, copper, silicon, beryllium, carbon, iron and
aluminium.

Elements found in small amounts include cadmium, mercury, and thallium.[40]

Elements found in trace amounts include americium, antimony, arsenic, barium, bismuth, boron,
cobalt, europium, gallium, germanium, gold, indium, lithium, manganese, nickel, niobium,
palladium, platinum, rhodium, ruthenium, selenium, silver, tantalum, terbium, thorium, titanium,
vanadium, and yttrium.

Almost all electronics contain lead and tin (as solder) and copper (as wire and printed circuit
board tracks), though the use of lead-free solder is now spreading rapidly.

EFFECTS ON ENVIRONMENT AND HUMAN HEALTH
Disposal of e-wastes is a particular problem faced in many regions across the globe. Computer
wastes that are landfilled produces contaminated leachates which eventually pollute the
groundwater. Acids and sludge obtained from melting computer chips, if disposed on the ground
causes acidification of soil. For example, Guiyu, Hong Kong a thriving area of illegal e-waste
recycling is facing acute water shortages due to the contamination of water resources.

This is due to disposal of recycling wastes such as acids, sludges etc. in rivers. Now water is
being transported from faraway towns to cater to the demands of the population. Incineration of
e-wastes can emit toxic fumes and gases, thereby polluting the surrounding air. Improperly
monitored landfills can cause environmental hazards. Mercury will leach when certain electronic
devices, such as circuit breakers are destroyed. The same is true for polychlorinated biphenyls
(PCBs) from condensers. When brominated flame retardant plastic or cadmium containing
plastics are landfilled, both polybrominated dlphenyl ethers (PBDE) and cadmium may leach
into the soil and groundwater. It has been found that significant amounts of lead ion are
dissolved from broken lead containing glass, such as the cone glass of cathode ray tubes, gets
mixed with acid waters and are a common occurrence in landfills.

Not only does the leaching of mercury poses specific problems, the vaporization of metallic
mercury and dimethylene mercury, both part of Waste Electrical and Electronic Equipment
(WEEE) is also of concern. In addition, uncontrolled fires may arise at landfills and this could be
a frequent occurrence in many countries. When exposed to fire, metals and other chemical
substances, such as the extremely toxic dioxins and furans (TCDD tetrachloro dibenzo-dioxin,
PCDDs-polychlorinated dibenzodioxins. PBDDs-polybrominated dibenzo-dioxin and PCDFs-
poly chlorinated dibenzo furans) from halogenated flame retardant products and PCB containing
condensers can be emitted. The most dangerous form of burning e-waste is the open-air burning
of plastics in order to recover copper and other metals. The toxic fall-out from open air burning
affects both the local environment and broader global air currents, depositing highly toxic by
products in many places throughout the world.

Table I summarizes the health effects of certain constituents in e-wastes. If these electronic items
are discarded with other household garbage, the toxics pose a threat to both health and vital
components of the ecosystem. In view of the ill-effects of hazardous wastes to both environment
and health, several countries exhorted the need for a global agreement to address the problems
and challenges posed by hazardous waste. Also, in the late 1980s, a tightening of environmental
regulations in industrialized countries led to a dramatic rise in the cost of hazardous waste
disposal. Searching for cheaper ways to get rid of the wastes, "toxic traders" began shipping
hazardous waste to developing countries. International outrage following these irresponsible
activities led to the drafting and adoption of strategic plans and regulations at the Basel
Convention. The Convention secretariat, in Geneva, Switzerland, facilitates and implementation
of the Convention and related agreements. It also provides assistance and guidelines on legal and
technical issues, gathers statistical data, and conducts training on the proper management of
hazardous waste.

MANAGEMENT OF E-WASTES

It is estimated that 75% of electronic items are stored due to uncertainty of how to manage it.
These electronic junks lie unattended in houses, offices, warehouses etc. and normally mixed
with household wastes, which are finally disposed off at landfills. This necessitates
implementable management measures.

In industries management of e-waste should begin at the point of generation. This can be done by
waste minimization techniques and by sustainable product design. Waste minimization in
industries involves adopting:

       inventory management,
       production-process modification,
       volume reduction,
       recovery and reuse.

Inventory management

Proper control over the materials used in the manufacturing process is an important way to
reduce waste generation (Freeman, 1989). By reducing both the quantity of hazardous materials
used in the process and the amount of excess raw materials in stock, the quantity of waste
generated can be reduced. This can be done in two ways i.e. establishing material-purchase
review and control procedures and inventory tracking system.

Developing review procedures for all material purchased is the first step in establishing an
inventory management program. Procedures should require that all materials be approved prior
to purchase. In the approval process all production materials are evaluated to examine if they
contain hazardous constituents and whether alternative non-hazardous materials are available.

Another inventory management procedure for waste reduction is to ensure that only the needed
quantity of a material is ordered. This will require the establishment of a strict inventory tracking
system. Purchase procedures must be implemented which ensure that materials are ordered only
on an as-needed basis and that only the amount needed for a specific period of time is ordered.

Production-process modification

Changes can be made in the production process, which will reduce waste generation. This
reduction can be accomplished by changing the materials used to make the product or by the
more efficient use of input materials in the production process or both. Potential waste
minimization techniques can be broken down into three categories:

i) Improved operating and maintenance procedures,

ii) Material change and

iii)Process-equipment modification.

Improvements in the operation and maintenance of process equipment can result in significant
waste reduction. This can be accomplished by reviewing current operational procedures or lack
of procedures and examination of the production process for ways to improve its efficiency.
Instituting standard operation procedures can optimise the use of raw materials in the production
process and reduce the potential for materials to be lost through leaks and spills. A strict
maintenance program, which stresses corrective maintenance, can reduce waste generation
caused by equipment failure. An employee-training program is a key element of any waste
reduction program. Training should include correct operating and handling procedures, proper
equipment use, recommended maintenance and inspection schedules, correct process control
specifications and proper management of waste materials.

Hazardous materials used in either a product formulation or a production process may be
replaced with a less hazardous or non-hazardous material. This is a very widely used technique
and is applicable to most manufacturing processes. Implementation of this waste reduction
technique may require only some minor process adjustments or it may require extensive new
process equipment. For example, a circuit board manufacturer can replace solvent-based product
with water-based flux and simultaneously replace solventvapor degreaser with detergent parts
washer.

Installing more efficient process equipment or modifying existing equipment to take advantage
of better production techniques can significantly reduce waste generation. New or updated
equipment can use process materials more efficiently producing less waste. Additionally such
efficiency reduces the number of rejected or off-specification products, thereby reducing the
amount of material which has to be reworked or disposed of. Modifying existing process
equipment can be a very cost-effective method of reducing waste generation. In many cases the
modification can just be relatively simple changes in the way the materials are handled within
the process to ensure that they are not wasted. For example, in many electronic manufacturing
operations, which involve coating a product, such as electroplating or painting, chemicals are
used to strip off coating from rejected products so that they can be recoated. These chemicals,
which can include acids, caustics, cyanides etc are often a hazardous waste and must be properly
managed. By reducing the number of parts that have to be reworked, the quantity of waste can be
significantly reduced.

Volume reduction

Volume reduction includes those techniques that remove the hazardous portion of a waste from a
non-hazardous portion. These techniques are usually to reduce the volume, and thus the cost of
disposing of a waste material. The techniques that can be used to reduce waste-stream volume
can be divided into 2 general categories: source segregation and waste concentration.
Segregation of wastes is in many cases a simple and economical technique for waste reduction.
Wastes containing different types of metals can be treated separately so that the metal value in
the sludge can be recovered. Concentration of a waste stream may increase the likelihood that the
material can be recycled or reused. Methods include gravity and vacuum filtration, ultra
filtration, reverse osmosis, freeze vaporization etc.

For example, an electronic component manufacturer can use compaction equipments to reduce
volume of waste cathode ray-tube.

Recovery and reuse

This technique could eliminate waste disposal costs, reduce raw material costs and provide
income from a salable waste. Waste can be recovered on-site, or at an off-site recovery facility,
or through inter industry exchange. A number of physical and chemical techniques are available
to reclaim a waste material such as reverse osmosis, electrolysis, condensation, electrolytic
recovery, filtration, centrifugation etc. For example, a printed-circuit board manufacturer can use
electrolytic recovery to reclaim metals from copper and tin-lead plating bath.

However recycling of hazardous products has little environmental benefit if it simply moves the
hazards into secondary products that eventually have to be disposed of. Unless the goal is to
redesign the product to use nonhazardous materials, such recycling is a false solution.

Sustainable product design

Minimization of hazardous wastes should be at product design stage itself keeping in mind the
following factors*

       Rethink the product design: Efforts should be made to design a product with fewer amounts of
       hazardous materials. For example, the efforts to reduce material use are reflected in some new
       computer designs that are flatter, lighter and more integrated. Other companies propose
       centralized networks similar to the telephone system.
       Use of renewable materials and energy: Bio-based plastics are plastics made with plant-based
       chemicals or plant-produced polymers rather than from petrochemicals. Bio-based toners, glues
and inks are used more frequently. Solar computers also exist but they are currently very
       expensive.
       Use of non-renewable materials that are safer: Because many of the materials used are non-
       renewable, designers could ensure the product is built for re-use, repair and/or upgradeability.
       Some computer manufacturers such as Dell and Gateway lease out their products thereby
       ensuring they get them back to further upgrade and lease out again.

Responsibilities of the Government

(i) Governments should set up regulatory agencies in each district, which are vested with the
responsibility of co-ordinating and consolidating the regulatory functions of the various
government authorities regarding hazardous substances.

(ii) Governments should be responsible for providing an adequate system of laws, controls and
administrative procedures for hazardous waste management (Third World Network. 1991).
Existing laws concerning e-waste disposal be reviewed and revamped. A comprehensive law that
provides e-waste regulation and management and proper disposal of hazardous wastes is
required. Such a law should empower the agency to control, supervise and regulate the relevant
activities of government departments.

Under this law, the agency concerned should

           o   Collect basic information on the materials from manufacturers, processors and importers
               and to maintain an inventory of these materials. The information should include toxicity
               and potential harmful effects.
           o   Identify potentially harmful substances and require the industry to test them for adverse
               health and environmental effects.
           o   Control risks from manufacture, processing, distribution, use and disposal of electronic
               wastes.
           o   Encourage beneficial reuse of "e-waste" and encouraging business activities that use
               waste". Set up programs so as to promote recycling among citizens and businesses.
           o   Educate e-waste generators on reuse/recycling options

(iii) Governments must encourage research into the development and standard of hazardous
waste management, environmental monitoring and the regulation of hazardous waste-disposal.

(iv) Governments should enforce strict regulations against dumping e-waste in the country by
outsiders. Where the laws are flouted, stringent penalties must be imposed. In particular,
custodial sentences should be preferred to paltry fines, which these outsiders / foreign nationals
can pay.

(v) Governments should enforce strict regulations and heavy fines levied on industries, which do
not practice waste prevention and recovery in the production facilities.

(vi) Polluter pays principle and extended producer responsibility should be adopted.

(vii) Governments should encourage and support NGOs and other organizations to involve
actively in solving the nation's e-waste problems.
(viii) Uncontrolled dumping is an unsatisfactory method for disposal of hazardous waste and
should be phased out.

(viii) Governments should explore opportunities to partner with manufacturers and retailers to
provide recycling services.

Responsibility and Role of industries

       1. Generators of wastes should take responsibility to determine the output characteristics
       of wastes and if hazardous, should provide management options.

       2. All personnel involved in handling e-waste in industries including those at the policy,
       management, control and operational levels, should be properly qualified and trained.
       Companies can adopt their own policies while handling
       e-wastes. Some are given below:

                      Use label materials to assist in recycling (particularly plastics).
                      Standardize components for easy disassembly.
                      Re-evaluate 'cheap products' use, make product cycle 'cheap' and so that it
                       has no inherent value that would encourage a recycling infrastructure.
                      Create computer components and peripherals of biodegradable materials.
                      Utilize technology sharing particularly for manufacturing and de manufacturing.
                      Encourage / promote / require green procurement for corporate buyers.
                      Look at green packaging options.

       3. Companies can and should adopt waste minimization techniques, which will make a
       significant reduction in the quantity of e-waste generated and thereby lessening the
       impact on the environment. It is a "reverse production" system that designs infrastructure
       to recover and reuse every material contained within e-wastes metals such as lead,
       copper, aluminum and gold, and various plastics, glass and wire. Such a "closed loop"
       manufacturing and recovery system offers a win-win situation for everyone, less of the
       Earth will be mined for raw materials, and groundwater will be protected, researchers
       explain.

       4. Manufacturers, distributors, and retailers should undertake the responsibility of
       recycling/disposal of their own products.

       5. Manufacturers of computer monitors, television sets and other electronic devices
       containing hazardous materials must be responsible for educating consumers and the
       general public regarding the potential threat to public health and the environment posed
       by their products. At minimum, all computer monitors, television sets and other
       electronic devices containing hazardous materials must be clearly labeled to identify
       environmental hazards and proper materials management.
Responsibilities of the Citizen

Waste prevention is perhaps more preferred to any other waste management option including
recycling. Donating electronics for reuse extends the lives of valuable products and keeps them
out of the waste management system for a longer time. But care should be taken while donating
such items i.e. the items should be in working condition.

Reuse, in addition to being an environmentally preferable alternative, also benefits society. By
donating used electronics, schools, non-profit organizations, and lower-income families can
afford to use equipment that they otherwise could not afford.

E-wastes should never be disposed with garbage and other household wastes. This should be
segregated at the site and sold or donated to various organizations.

While buying electronic products opt for those that:

            o   are made with fewer toxic constituents
            o   use recycled content
            o   are energy efficient
            o   are designed for easy upgrading or disassembly
            o   utilize minimal packaging
            o   offer leasing or take back options
            o   have been certified by regulatory authorities. Customers should
                opt for upgrading their computers or other electronic items to the
                latest versions rather than buying new equipments.

NGOs should adopt a participatory approach in management of e-wastes

  • 1. Electronic waste, e-waste, e-scrap, or Waste Electrical and Electronic Equipment (WEEE) describes discarded electrical or electronic devices. There is a lack of consensus as to whether the term should apply to resale, reuse, and refurbishing industries, or only to product that cannot be used for its intended purpose. Informal processing of electronic waste in developing countries may cause serious health and pollution problems, though these countries are also most likely to reuse and repair electronics. Some electronic scrap components, such as CRTs, may contain contaminants such as lead, cadmium, beryllium, or brominated flame retardants. Even in developed countries recycling and disposal of e-waste may involve significant risk to workers and communities and great care must be taken to avoid unsafe exposure in recycling operations and leaching of material such as heavy metals from landfills and incinerator ashes. Scrap industry and USA EPA officials agree that materials should be managed with caution, but many believe that environmental dangers of used electronics have been exaggerated. Problems Rapid changes in technology, changes in media (tapes, software, MP3), falling prices, and planned obsolescence have resulted in a fast-growing surplus of electronic waste around the globe. Dave Kruch, CEO of Cash For Laptops, regards electronic waste as a "rapidly expanding" issue. Technical solutions are available, but in most cases a legal framework, a collection system, logistics, and other services need to be implemented before a technical solution can be applied. Display units (CRT, LCD, LED monitors), Processors (CPU chips, RAM), and audio components have different useful lives. Processors are most frequently outdated (by software) and are more likely to become "e-waste", while display units are most often replaced while working without repair attempts, due to changes in wealthy nation appetites for new display technology. An estimated 50 million tons of E-waste are produced each year[]. The USA discards 30 million computers each year and 100 million phones are disposed of in Europe each year. The Environmental Protection Agency estimates that only 15-20% of e-waste is recycled, the rest of these electronics go directly into landfills and incinerators."EPA estimates for 2006-7".. According to a report by UNEP titled, "Recycling - from E-Waste to Resources," the amount of e-waste being produced - including mobile phones and computers - could rise by as much as 500 percent over the next decade in some countries, such as India. The United States is the world leader in producing electronic waste, tossing away about 3 million tons each year. China already produces about 2.3 million tons (2010 estimate) domestically, second only to the United States. And, despite having banned e-waste imports, China remains a major e-waste dumping ground for developed countries. Electrical waste contains hazardous but also valuable and scarce materials. Up to 60 elements can be found in complex electronics. In the United States, an estimated 70% of heavy metals in landfills comes from discarded electronics.
  • 2. While there is agreement that the number of discarded electronic devices is increasing, there is considerable disagreement about the relative risk (compared to automobile scrap, for example), and strong disagreement whether curtailing trade in used electronics will improve conditions, or make them worse. According to an article in Motherboard, attempts to restrict the trade have driven reputable companies out of the supply chain, with unintended consequences. Global trade issues One theory is that increased regulation of electronic waste and concern over the environmental harm in mature economies creates an economic disincentive to remove residues prior to export. Critics of trade in used electronics maintain that it is too easy for brokers calling themselves recyclers to export unscreened electronic waste to developing countries, such as China, India and parts of Africa, thus avoiding the expense of removing items like bad cathode ray tubes (the processing of which is expensive and difficult). The developing countries are becoming big dump yards of e-waste. Proponents of international trade point to the success of fair trade programs in other industries, where cooperation has led creation of sustainable jobs, and can bring affordable technology in countries where repair and reuse rates are higher. Defenders of the trade in used electronics say that extraction of metals from virgin mining has also been shifted to developing countries. Hard-rock mining of copper, silver, gold and other materials extracted from electronics is considered far more environmentally damaging than the recycling of those materials. They also state that repair and reuse of computers and televisions has become a "lost art" in wealthier nations, and that refurbishing has traditionally been a path to development. South Korea, Taiwan, and southern China all excelled in finding "retained value" in used goods, and in some cases have set up billion-dollar industries in refurbishing used ink cartridges, single-use cameras, and working CRTs. Refurbishing has traditionally been a threat to established manufacturing, and simple protectionism explains some criticism of the trade. Works like "The Waste Makers" by Vance Packard explain some of the criticism of exports of working product, for example the ban on import of tested working Pentium 4 laptops to China, or the bans on export of used surplus working electronics by Japan. Opponents of surplus electronics exports argue that lower environmental and labor standards, cheap labor, and the relatively high value of recovered raw materials leads to a transfer of pollution-generating activities, such as burning of copper wire. In China, Malaysia, India, Kenya, and various African countries, electronic waste is being sent to these countries for processing, sometimes illegally. Many surplus laptops are routed to developing nations as "dumping grounds for e-waste". Because the United States has not ratified the Basel Convention or its Ban Amendment, and has no domestic laws forbidding the export of toxic waste, the Basel Action Network estimates that about 80% of the electronic waste directed to recycling in the U.S. does not get recycled there at all, but is put on container ships and sent to countries such as China. This figure is disputed as an
  • 3. exaggeration by the EPA, the Institute of Scrap Recycling Industries, and the World Reuse, Repair and Recycling Association. Independent research by Arizona State University showed that 87-88% of imported used computers did not have a higher value than the best value of the constituent materials they contained, and that "the official trade in end-of-life computers is thus driven by reuse as opposed to recycling". Guiyu in the Shantou region of China, Delhi and Bangalore in India as well as the Agbogbloshie site near Accra, Ghana have electronic waste processing areas. Uncontrolled burning, disassembly, and disposal causes a variety of environmental problems such as groundwater contamination, atmospheric pollution, or even water pollution either by immediate discharge or due to surface runoff (especially near coastal areas), as well as health problems including occupational safety and health effects among those directly and indirectly involved, due to the methods of processing the waste. Thousands of men, women, and children are employed in highly polluting, primitive recycling technologies, extracting the metals, toners, and plastics from computers and other electronic waste. Recent studies show that 7 out of 10 children in this region have too much lead in their blood. Proponents of the trade say growth of internet access is a stronger correlation to trade than poverty. Haiti is poor and closer to the port of New York than southeast Asia, but far more electronic waste is exported from New York to Asia than to Haiti. Thousands of men, women, and children are employed in reuse, refurbishing, repair, and remanufacturing, unsustainable industries in decline in developed countries. Denying developing nations access to used electronics may deny them sustainable employment, affordable products, and internet access, or force them to deal with even less scrupulous suppliers. In a series of seven articles for The Atlantic, Shanghai-based reporter Adam Minter describes many of these computer repair and scrap separation activities as objectively sustainable. Opponents of the trade argue that developing countries utilize methods that are more harmful and more wasteful. An expedient and prevalent method is simply to toss equipment onto an open fire, in order to melt plastics and to burn away unvaluable metals. This releases carcinogens and neurotoxins into the air, contributing to an acrid, lingering smog. These noxious fumes include dioxins and furans. Bonfire refuse can be disposed of quickly into drainage ditches or waterways feeding the ocean or local water supplies. In June 2008, a container of electronic waste, destined from the Port of Oakland in the U.S. to Sanshui District in mainland China, was intercepted in Hong Kong by Greenpeace.Concern over exports of electronic waste were raised in press reports in India, Ghana, Ivory Coastand Nigeria. Ewaste management Recycling
  • 4. Today the electronic waste recycling business is in all areas of the developed world a large and rapidly consolidating business. Part of this evolution has involved greater diversion of electronic waste from energy-intensive downcycling processes (e.g., conventional recycling), where equipment is reverted to a raw material form. This diversion is achieved through reuse and refurbishing. The environmental and social benefits of reuse include diminished demand for new products and virgin raw materials (with their own environmental issues); larger quantities of pure water and electricity for associated manufacturing; less packaging per unit; availability of technology to wider swaths of society due to greater affordability of products; and diminished use of landfills. Audiovisual components, televisions, VCRs, stereo equipment, mobile phones, other handheld devices, and computer components contain valuable elements and substances suitable for reclamation, including lead, copper, and gold. One of the major challenges is recycling the printed circuit boards from the electronic wastes. The circuit boards contain such precious metals as gold, silver, platinum, etc. and such base metals as copper, iron, aluminum, etc. Conventional method employed is mechanical shredding and separation but the recycling efficiency is low. Alternative methods such as cryogenic decomposition have been studied for printed circuit board recycling, and some other methods are still under investigation. n developed countries, electronic waste processing usually first involves dismantling the equipment into various parts (metal frames, power supplies, circuit boards, plastics), often by hand, but increasingly by automated shredding equipment. A typical example is the NADIN electronic waste processing plant in Novi Iskar, Bulgaria -- the largest facility of its kind in Eastern Europe. The advantages of this process are the human's ability to recognize and save working and repairable parts, including chips, transistors, RAM, etc. The disadvantage is that the labor is cheapest in countries with the lowest health and safety standards. In an alternative bulk system, a hopper conveys material for shredding into an unsophisticated mechanical separator, with screening and granulating machines to separate constituent metal and plastic fractions, which are sold to smelters or plastics recyclers. Such recycling machinery is enclosed and employs a dust collection system. Some of the emissions are caught by scrubbers and screens. Magnets, eddy currents, and trommel screens are employed to separate glass, plastic, and ferrous and nonferrous metals, which can then be further separated at a smelter. Leaded glass from CRTs is reused in car batteries, ammunition, and lead wheel weights, or sold to foundries as a fluxing agent in processing raw lead ore. Copper, gold, palladium, silver and tin are valuable metals sold to smelters for recycling. Hazardous smoke and gases are captured, contained and treated to mitigate environmental threat. These methods allow for safe reclamation of all valuable computer construction materials. Hewlett-Packard product recycling solutions manager Renee St. Denis describes its process as: "We move them through giant shredders about 30 feet tall and it shreds everything into pieces about the size of a quarter. Once your disk drive is shredded into pieces about this big, it's hard to get the data off". An ideal electronic waste recycling plant combines dismantling for component recovery with increased cost-effective processing of bulk electronic waste.
  • 5. Reuse is an alternative option to recycling because it extends the lifespan of a device. Devices still need eventual recycling, but by allowing others to purchase used electronics, recycling can be postponed and value gained from device use. Benefits of recycling Recycling raw materials from end-of-life electronics is the most effective solution to the growing e-waste problem. Most electronic devices contain a variety of materials, including metals that can be recovered for future uses. By dismantling and providing reuse possibilities, intact natural resources are conserved and air and water pollution caused by hazardous disposal is avoided. Additionally, recycling reduces the amount of greenhouse gas emissions caused by the manufacturing of new products. It simply makes good sense and is efficient to recycle and to do our part to keep the environment green. Electronic waste substances Several sizes of button and coin cell with 2 9v batteries as a size comparison. They are all recycled in many countries since they contain lead, mercury and cadmium. Some computer components can be reused in assembling new computer products, while others are reduced to metals that can be reused in applications as varied as construction, flatware, and jewelry. Substances found in large quantities include epoxy resins, fiberglass, PCBs, PVC (polyvinyl chlorides), thermosetting plastics, lead, tin, copper, silicon, beryllium, carbon, iron and aluminium. Elements found in small amounts include cadmium, mercury, and thallium.[40] Elements found in trace amounts include americium, antimony, arsenic, barium, bismuth, boron, cobalt, europium, gallium, germanium, gold, indium, lithium, manganese, nickel, niobium, palladium, platinum, rhodium, ruthenium, selenium, silver, tantalum, terbium, thorium, titanium, vanadium, and yttrium. Almost all electronics contain lead and tin (as solder) and copper (as wire and printed circuit board tracks), though the use of lead-free solder is now spreading rapidly. EFFECTS ON ENVIRONMENT AND HUMAN HEALTH
  • 6. Disposal of e-wastes is a particular problem faced in many regions across the globe. Computer wastes that are landfilled produces contaminated leachates which eventually pollute the groundwater. Acids and sludge obtained from melting computer chips, if disposed on the ground causes acidification of soil. For example, Guiyu, Hong Kong a thriving area of illegal e-waste recycling is facing acute water shortages due to the contamination of water resources. This is due to disposal of recycling wastes such as acids, sludges etc. in rivers. Now water is being transported from faraway towns to cater to the demands of the population. Incineration of e-wastes can emit toxic fumes and gases, thereby polluting the surrounding air. Improperly monitored landfills can cause environmental hazards. Mercury will leach when certain electronic devices, such as circuit breakers are destroyed. The same is true for polychlorinated biphenyls (PCBs) from condensers. When brominated flame retardant plastic or cadmium containing plastics are landfilled, both polybrominated dlphenyl ethers (PBDE) and cadmium may leach into the soil and groundwater. It has been found that significant amounts of lead ion are dissolved from broken lead containing glass, such as the cone glass of cathode ray tubes, gets mixed with acid waters and are a common occurrence in landfills. Not only does the leaching of mercury poses specific problems, the vaporization of metallic mercury and dimethylene mercury, both part of Waste Electrical and Electronic Equipment (WEEE) is also of concern. In addition, uncontrolled fires may arise at landfills and this could be a frequent occurrence in many countries. When exposed to fire, metals and other chemical substances, such as the extremely toxic dioxins and furans (TCDD tetrachloro dibenzo-dioxin, PCDDs-polychlorinated dibenzodioxins. PBDDs-polybrominated dibenzo-dioxin and PCDFs- poly chlorinated dibenzo furans) from halogenated flame retardant products and PCB containing condensers can be emitted. The most dangerous form of burning e-waste is the open-air burning of plastics in order to recover copper and other metals. The toxic fall-out from open air burning affects both the local environment and broader global air currents, depositing highly toxic by products in many places throughout the world. Table I summarizes the health effects of certain constituents in e-wastes. If these electronic items are discarded with other household garbage, the toxics pose a threat to both health and vital components of the ecosystem. In view of the ill-effects of hazardous wastes to both environment and health, several countries exhorted the need for a global agreement to address the problems and challenges posed by hazardous waste. Also, in the late 1980s, a tightening of environmental regulations in industrialized countries led to a dramatic rise in the cost of hazardous waste disposal. Searching for cheaper ways to get rid of the wastes, "toxic traders" began shipping hazardous waste to developing countries. International outrage following these irresponsible activities led to the drafting and adoption of strategic plans and regulations at the Basel Convention. The Convention secretariat, in Geneva, Switzerland, facilitates and implementation of the Convention and related agreements. It also provides assistance and guidelines on legal and technical issues, gathers statistical data, and conducts training on the proper management of hazardous waste. Source of e-wastes Constituent

MANAGEMENT OF E-WASTES It is estimated that 75% of electronic items are stored due to uncertainty of how to manage it. These electronic junks lie unattended in houses, offices, warehouses etc. and normally mixed with household wastes, which are finally disposed off at landfills. This necessitates implementable management measures. In industries management of e-waste should begin at the point of generation. This can be done by waste minimization techniques and by sustainable product design. Waste minimization in industries involves adopting: inventory management, production-process modification, volume reduction, recovery and reuse. Inventory management Proper control over the materials used in the manufacturing process is an important way to reduce waste generation (Freeman, 1989). By reducing both the quantity of hazardous materials used in the process and the amount of excess raw materials in stock, the quantity of waste generated can be reduced. This can be done in two ways i.e. establishing material-purchase review and control procedures and inventory tracking system. Developing review procedures for all material purchased is the first step in establishing an inventory management program. Procedures should require that all materials be approved prior
  • 9. to purchase. In the approval process all production materials are evaluated to examine if they contain hazardous constituents and whether alternative non-hazardous materials are available. Another inventory management procedure for waste reduction is to ensure that only the needed quantity of a material is ordered. This will require the establishment of a strict inventory tracking system. Purchase procedures must be implemented which ensure that materials are ordered only on an as-needed basis and that only the amount needed for a specific period of time is ordered. Production-process modification Changes can be made in the production process, which will reduce waste generation. This reduction can be accomplished by changing the materials used to make the product or by the more efficient use of input materials in the production process or both. Potential waste minimization techniques can be broken down into three categories: i) Improved operating and maintenance procedures, ii) Material change and iii)Process-equipment modification. Improvements in the operation and maintenance of process equipment can result in significant waste reduction. This can be accomplished by reviewing current operational procedures or lack of procedures and examination of the production process for ways to improve its efficiency. Instituting standard operation procedures can optimise the use of raw materials in the production process and reduce the potential for materials to be lost through leaks and spills. A strict maintenance program, which stresses corrective maintenance, can reduce waste generation caused by equipment failure. An employee-training program is a key element of any waste reduction program. Training should include correct operating and handling procedures, proper equipment use, recommended maintenance and inspection schedules, correct process control specifications and proper management of waste materials. Hazardous materials used in either a product formulation or a production process may be replaced with a less hazardous or non-hazardous material. This is a very widely used technique and is applicable to most manufacturing processes. Implementation of this waste reduction technique may require only some minor process adjustments or it may require extensive new process equipment. For example, a circuit board manufacturer can replace solvent-based product with water-based flux and simultaneously replace solventvapor degreaser with detergent parts washer. Installing more efficient process equipment or modifying existing equipment to take advantage of better production techniques can significantly reduce waste generation. New or updated equipment can use process materials more efficiently producing less waste. Additionally such efficiency reduces the number of rejected or off-specification products, thereby reducing the amount of material which has to be reworked or disposed of. Modifying existing process equipment can be a very cost-effective method of reducing waste generation. In many cases the
  • 10. modification can just be relatively simple changes in the way the materials are handled within the process to ensure that they are not wasted. For example, in many electronic manufacturing operations, which involve coating a product, such as electroplating or painting, chemicals are used to strip off coating from rejected products so that they can be recoated. These chemicals, which can include acids, caustics, cyanides etc are often a hazardous waste and must be properly managed. By reducing the number of parts that have to be reworked, the quantity of waste can be significantly reduced. Volume reduction Volume reduction includes those techniques that remove the hazardous portion of a waste from a non-hazardous portion. These techniques are usually to reduce the volume, and thus the cost of disposing of a waste material. The techniques that can be used to reduce waste-stream volume can be divided into 2 general categories: source segregation and waste concentration. Segregation of wastes is in many cases a simple and economical technique for waste reduction. Wastes containing different types of metals can be treated separately so that the metal value in the sludge can be recovered. Concentration of a waste stream may increase the likelihood that the material can be recycled or reused. Methods include gravity and vacuum filtration, ultra filtration, reverse osmosis, freeze vaporization etc. For example, an electronic component manufacturer can use compaction equipments to reduce volume of waste cathode ray-tube. Recovery and reuse This technique could eliminate waste disposal costs, reduce raw material costs and provide income from a salable waste. Waste can be recovered on-site, or at an off-site recovery facility, or through inter industry exchange. A number of physical and chemical techniques are available to reclaim a waste material such as reverse osmosis, electrolysis, condensation, electrolytic recovery, filtration, centrifugation etc. For example, a printed-circuit board manufacturer can use electrolytic recovery to reclaim metals from copper and tin-lead plating bath. However recycling of hazardous products has little environmental benefit if it simply moves the hazards into secondary products that eventually have to be disposed of. Unless the goal is to redesign the product to use nonhazardous materials, such recycling is a false solution. Sustainable product design Minimization of hazardous wastes should be at product design stage itself keeping in mind the following factors* Rethink the product design: Efforts should be made to design a product with fewer amounts of hazardous materials. For example, the efforts to reduce material use are reflected in some new computer designs that are flatter, lighter and more integrated. Other companies propose centralized networks similar to the telephone system. Use of renewable materials and energy: Bio-based plastics are plastics made with plant-based chemicals or plant-produced polymers rather than from petrochemicals. Bio-based toners, glues
  • 11. and inks are used more frequently. Solar computers also exist but they are currently very expensive. Use of non-renewable materials that are safer: Because many of the materials used are non- renewable, designers could ensure the product is built for re-use, repair and/or upgradeability. Some computer manufacturers such as Dell and Gateway lease out their products thereby ensuring they get them back to further upgrade and lease out again. Responsibilities of the Government (i) Governments should set up regulatory agencies in each district, which are vested with the responsibility of co-ordinating and consolidating the regulatory functions of the various government authorities regarding hazardous substances. (ii) Governments should be responsible for providing an adequate system of laws, controls and administrative procedures for hazardous waste management (Third World Network. 1991). Existing laws concerning e-waste disposal be reviewed and revamped. A comprehensive law that provides e-waste regulation and management and proper disposal of hazardous wastes is required. Such a law should empower the agency to control, supervise and regulate the relevant activities of government departments. Under this law, the agency concerned should o Collect basic information on the materials from manufacturers, processors and importers and to maintain an inventory of these materials. The information should include toxicity and potential harmful effects. o Identify potentially harmful substances and require the industry to test them for adverse health and environmental effects. o Control risks from manufacture, processing, distribution, use and disposal of electronic wastes. o Encourage beneficial reuse of "e-waste" and encouraging business activities that use waste". Set up programs so as to promote recycling among citizens and businesses. o Educate e-waste generators on reuse/recycling options (iii) Governments must encourage research into the development and standard of hazardous waste management, environmental monitoring and the regulation of hazardous waste-disposal. (iv) Governments should enforce strict regulations against dumping e-waste in the country by outsiders. Where the laws are flouted, stringent penalties must be imposed. In particular, custodial sentences should be preferred to paltry fines, which these outsiders / foreign nationals can pay. (v) Governments should enforce strict regulations and heavy fines levied on industries, which do not practice waste prevention and recovery in the production facilities. (vi) Polluter pays principle and extended producer responsibility should be adopted. (vii) Governments should encourage and support NGOs and other organizations to involve actively in solving the nation's e-waste problems.
  • 12. (viii) Uncontrolled dumping is an unsatisfactory method for disposal of hazardous waste and should be phased out. (viii) Governments should explore opportunities to partner with manufacturers and retailers to provide recycling services. Responsibility and Role of industries 1. Generators of wastes should take responsibility to determine the output characteristics of wastes and if hazardous, should provide management options. 2. All personnel involved in handling e-waste in industries including those at the policy, management, control and operational levels, should be properly qualified and trained. Companies can adopt their own policies while handling e-wastes. Some are given below:  Use label materials to assist in recycling (particularly plastics).  Standardize components for easy disassembly.  Re-evaluate 'cheap products' use, make product cycle 'cheap' and so that it has no inherent value that would encourage a recycling infrastructure.  Create computer components and peripherals of biodegradable materials.  Utilize technology sharing particularly for manufacturing and de manufacturing.  Encourage / promote / require green procurement for corporate buyers.  Look at green packaging options. 3. Companies can and should adopt waste minimization techniques, which will make a significant reduction in the quantity of e-waste generated and thereby lessening the impact on the environment. It is a "reverse production" system that designs infrastructure to recover and reuse every material contained within e-wastes metals such as lead, copper, aluminum and gold, and various plastics, glass and wire. Such a "closed loop" manufacturing and recovery system offers a win-win situation for everyone, less of the Earth will be mined for raw materials, and groundwater will be protected, researchers explain. 4. Manufacturers, distributors, and retailers should undertake the responsibility of recycling/disposal of their own products. 5. Manufacturers of computer monitors, television sets and other electronic devices containing hazardous materials must be responsible for educating consumers and the general public regarding the potential threat to public health and the environment posed by their products. At minimum, all computer monitors, television sets and other electronic devices containing hazardous materials must be clearly labeled to identify environmental hazards and proper materials management.
  • 13. Responsibilities of the Citizen Waste prevention is perhaps more preferred to any other waste management option including recycling. Donating electronics for reuse extends the lives of valuable products and keeps them out of the waste management system for a longer time. But care should be taken while donating such items i.e. the items should be in working condition. Reuse, in addition to being an environmentally preferable alternative, also benefits society. By donating used electronics, schools, non-profit organizations, and lower-income families can afford to use equipment that they otherwise could not afford. E-wastes should never be disposed with garbage and other household wastes. This should be segregated at the site and sold or donated to various organizations. While buying electronic products opt for those that: o are made with fewer toxic constituents o use recycled content o are energy efficient o are designed for easy upgrading or disassembly o utilize minimal packaging o offer leasing or take back options o have been certified by regulatory authorities. Customers should opt for upgrading their computers or other electronic items to the latest versions rather than buying new equipments. NGOs should adopt a participatory approach in management of e-wastes
