   Electronic waste or e-waste describes discarded electrical or
   electronic devices. Used electronics which are destined for
   refurbishment, reuse, resale, salvage recycling through material
   recovery, or disposal are also considered e-waste. Informal processing
   of e-waste in developing countries can lead to adverse human health
   effects and environmental pollution.

   Electronic scrap components, such as CPUs, contain potentially harmful
   materials such as lead, cadmium, beryllium, or brominated flame
   retardants. Recycling and disposal of e-waste may involve significant
   risk to health of workers and their communities.^[1]

Definition[edit]

   Hoarding (first), disassembling (second) and collecting (third)
   electronic waste in Bengaluru, India

   E-waste or electronic waste is created when an electronic product is
   discarded after the end of its useful life. The rapid expansion of
   technology and the consumption driven society results in the creation
   of a very large amount of e-waste.

   In the US, the United States Environmental Protection Agency (EPA)
   classifies waste into ten categories:
    1. Large household appliances, including cooling and freezing
       appliances
    2. Small household appliances
    3. IT equipment, including monitors
    4. Consumer electronics, including televisions
    5. Lamps and luminaires
    6. Toys
    7. Tools
    8. Medical devices
    9. Monitoring and control instruments and
   10. Automatic dispensers

   These include used electronics which are destined for reuse, resale,
   salvage, recycling, or disposal as well as re-usables (working and
   repairable electronics) and secondary raw materials (copper, steel,
   plastic, or similar). The term "waste" is reserved for residue or
   material which is dumped by the buyer rather than recycled, including
   residue from reuse and recycling operations, because loads of surplus
   electronics are frequently commingled (good, recyclable, and
   non-recyclable). Several public policy advocates apply the term
   "e-waste" and "e-scrap" broadly to apply to all surplus electronics.
   Cathode ray tubes (CRTs) are considered one of the hardest types to
   recycle.^[2]

   Using a different set of categories, the Partnership on Measuring ICT
   for Development defines e-waste in six categories:
    1. Temperature exchange equipment (such as air conditioners, freezers)
    2. Screens, monitors (TVs, laptops)
    3. Lamps (LED lamps, for example)
    4. Large equipment (washing machines, electric stoves)
    5. Small equipment (microwaves, electric shavers) and
    6. Small IT and telecommunication equipment (such as mobile phones,
       printers)

   Products in each category vary in longevity profile, impact, and
   collection methods, among other differences.^[3]

   CRTs have a relatively high concentration of lead and phosphors (not to
   be confused with phosphorus), both of which are necessary for the
   display. The United States Environmental Protection Agency (EPA)
   includes discarded CRT monitors in its category of "hazardous household
   waste"^[4] but considers CRTs that have been set aside for testing to
   be commodities if they are not discarded, speculatively accumulated, or
   left unprotected from weather and other damage. These CRT devices are
   often confused between the DLP Rear Projection TV, both of which have a
   different recycling process due to the materials of which they are
   composed.

   The EU and its member states operate a system via the European Waste
   Catalogue (EWC) - a European Council Directive, which is interpreted
   into "member state law". In the UK, this is in the form of the List of
   Wastes Directive. However, the list (and EWC) gives a broad definition
   (EWC Code 16 02 13*) of what is hazardous electronic waste, requiring
   "waste operators" to employ the Hazardous Waste Regulations (Annex 1A,
   Annex 1B) for refined definition. Constituent materials in the waste
   also require assessment via the combination of Annex II and Annex III,
   again allowing operators to further determine whether a waste is
   hazardous.^[5]

   Debate continues over the distinction between "commodity" and "waste"
   electronics definitions. Some exporters are accused of deliberately
   leaving difficult-to-recycle, obsolete, or non-repairable equipment
   mixed in loads of working equipment (though this may also come through
   ignorance, or to avoid more costly treatment processes). Protectionists
   may broaden the definition of "waste" electronics in order to protect
   domestic markets from working secondary equipment.

   The high value of the computer recycling subset of electronic waste
   (working and reusable laptops, desktops, and components like RAM) can
   help pay the cost of transportation for a larger number of worthless
   pieces than what can be achieved with display devices, which have less
   (or negative) scrap value. In A 2011 report, "Ghana E-Waste Country
   Assessment",^[6] found that of 215,000 tons of electronics imported to
   Ghana, 30% were brand new and 70% were used. Of the used product, the
   study concluded that 15% was not reused and was scrapped or discarded.
   This contrasts with published but uncredited claims that 80% of the
   imports into Ghana were being burned in primitive conditions.

Quantity[edit]

   E-waste is considered the "fastest-growing waste stream in the
   world"^[7] with 44.7 million tonnes generated in 2016- equivalent to
   4500 Eiffel towers.^[3] In 2018, an estimated 50 million tonnes of
   e-waste was reported, thus the name `tsunami of e-waste' given by the
   UN.^[7] Its value is at least $62.5 billion annually.^[7]

   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. Technical
   solutions are available, but in most cases, a legal framework, a
   collection, logistics, and other services need to be implemented before
   a technical solution can be applied.

   Display units (CRT, LCD, LED monitors), processors (CPU, GPU, or APU
   chips), memory (DRAM or SRAM), and audio components have different
   useful lives. Processors are most frequently out-dated (by software no
   longer being optimized) 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. This problem could potentially be solved with modular
   smartphones (such as the Phonebloks concept). These types of phones are
   more durable and have the technology to change certain parts of the
   phone making them more environmentally friendly. Being able to simply
   replace the part of the phone that is broken will reduce e-waste.^[8]
   An estimated 50 million tons of E-waste are produced each year.^[9] 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.^[10]^[11]
   Electronic waste at Agbogbloshie, Ghana

   In 2006, the United Nations estimated the amount of worldwide
   electronic waste discarded each year to be 50 million metric tons.^[12]
   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.^[13] The United States is
   the world leader in producing electronic waste, tossing away about 3
   million tons each year.^[14] 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.^[14]
   An iPhone with a damaged screen

   Society today revolves around technology and by the constant need for
   the newest and most high-tech products we are contributing to a mass
   amount of e-waste.^[15] Since the invention of the iPhone, cell phones
   have become the top source of e-waste products because they are not
   made to last more than two years.^[citation needed] Electrical waste
   contains hazardous but also valuable and scarce materials. Up to 60
   elements can be found in complex electronics.^[16] As of 2013, Apple
   has sold over 796 million iDevices (iPod, iPhone, iPad). Cell phone
   companies make cell phones that are not made to last so that the
   consumer will purchase new phones. Companies give these products such
   short lifespans because they know that the consumer will want a new
   product and will buy it if they make it.^[17]^[better source needed] In
   the United States, an estimated 70% of heavy metals in landfills comes
   from discarded electronics.^[18]^[19]

   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.^[20]

E-waste data 2016[edit]

   In 2016, Asia was the territory that brought about by significant the
   most extensive volume of e-waste (18.2 Mt), accompanied by Europe (12.3
   metric tons), America (11.3 metric tons), Africa (2.2 metric tons), and
   Oceania (0.7 metric tons). The smallest in terms of total e-waste made,
   Oceania was the largest generator of e-waste per capita
   (17.3 kg/inhabitant), with hardly 6% of e-waste cited to be gathered
   and recycled. Europe is the second broadest generator of e-waste per
   citizen, with an average of 16.6 kg/inhabitant; however, Europe bears
   the loftiest assemblage figure (35%). America generates
   11.6 kg/inhabitant and solicits only 17% of the e-waste caused in the
   provinces, which is commensurate with the assortment count in Asia
   (15%). However, Asia generates fewer e-waste per citizen
   (4,2 kg/inhabitant). Africa generates only 1.9 kg/inhabitant, and
   limited information is available on its collection percentage. The
   record furnishes regional breakdowns for Africa, Americas, Asia,
   Europe, and Oceania. The phenomenon somewhat illustrates the modest
   number figure linked to the overall volume of e-waste made that 41
   countries have administrator e-waste data. For 16 other countries,
   e-waste volumes were collected from exploration and evaluated. The
   outcome of a considerable bulk of the e-waste (34.1 Metric tons) is
   unidentified. In countries where there is no national e-waste
   constitution in the stand, e-waste is possible interpreted as an
   alternative or general waste. This is land-filled or recycled, along
   with alternative metal or plastic scraps. There is the colossal
   compromise that the toxins are not drawn want of accordingly, or they
   are chosen want of by an informal sector and converted without well
   safeguarding the laborers while venting the contaminations in e-waste.
   Although the e-waste claim is on the rise, a flourishing quantity of
   countries are embracing e-waste regulation. National e-waste governance
   orders enclose 66% of the world population, a rise from 44% that was
   reached in 2014^[21]

E-waste data 2019[edit]

   In 2019, an enormous volume of e-waste (53.6 Mt, with a 7.3 kg per
   capita average) was generated globally. This is projected to increase
   to 4.7 Mt by the year 2030. Asia still remains the largest contributor
   of a significant volume of electronic waste at 24.9 Mt, followed by the
   Americas (13.1 Mt), Europe (12 Mt), and Africa and Oceania at 2.9 Mt
   and 0.7 Mt, respectively. In per capita generation, Europe came first
   with 16.2 kg, and Oceania was second largest generator at 16.1 kg, and
   followed by the Americas. Africa is the least generator of e-waste per
   capita at 2.5 kg. Regarding the collection and recycling of these
   waste, the continent of Europe ranked first (42.5%), and Asia came
   second (11.7%). The Americas and Oceania are next (9.4% and 8.8%
   respectively), and Africa trails behind at 0.9%. Out of the 53.6 Metric
   tons generated e-waste globally, the formally documented collection and
   recycling was 9.3%, and the fate of 44.3% remains uncertain, with its
   whereabouts and impact to the environment varying across different
   regions of the world. However, the number of countries with national
   e-waste legislation, regulation or policy, have increased since 2014,
   from 61 to 78. A great proportion of undocumented commercial and
   domestic waste get mixed with other streams of waste like plastic and
   metal waste, implying that fractions which are easily recyclable might
   be recycled, under conditions considered to be inferior without
   depollution and recovery of all materials considered valuable. As a
   result, it is not the most preferred form of recycling. The management
   infrastructure of e-waste in middle- and low-income countries are still
   not fully developed, and is absent in some cases. The informal sector
   is responsible for the management, at the risk of inferior conditions
   of recycling that might cause dire health effects to the workers and
   their children, who might live, play and work near sites of e-waste
   management.^[22]

E-waste legislative frameworks[edit]

   The European Union (EU) has addressed the issue of electronic Waste by
   introducing two pieces of legislation. The first, the Waste Electrical
   and Electronic Equipment Directive (WEEE Directive) came into force in
   2003. [2] The main aim of this directive was to regulate and motivate
   electronic waste recycling and re-use in member states at that moment.
   It was revised in 2008, coming into force in 2014.[3] Furthermore, the
   EU has also implemented the Directive on the restriction of the use of
   certain hazardous substances in electrical and electronica equipment
   from 2003.[4] This documents was additionally revised in 2012.[5] When
   it comes to Western Balkan countries, North Macedonia has adopted a Law
   on Batteries and Accumulators in 2010, followed by the Law on
   Management of electrical and electronic equipment in 2012. Serbia has
   regulated management of special waste stream, including electronic
   waste, by National waste management strategy (2010-2019).[6] Montenegro
   has adopted Concessionary Act concerning electronic waste with ambition
   to collect 4 kg of this waste annually per person until 2020.[7]
   Albanian legal framework is based on the draft act on waste from
   electrical and electronic equipment from 2011 which focuses on the
   design of electrical and electronic equipment. Contrary to this, Bosnia
   and Herzegovina is still missing a law regulating electronic waste.

   As of October 2019, 78 countries globally have established either a
   policy, legislation or specific regulation to govern e-waste.^[23]
   However, there is no clear indication that countries are following the
   regulations. Regions such as Asia and Africa are having policies that
   are not legally binding and rather only programmatic ones.^[24] Hence,
   this poses as a challenge that e-waste management policies are yet not
   fully developed by globally by countries.

The Solving the E-waste Problem (StEP) initiative[edit]

   Solving the E-waste Problem is a membership organization that is part
   of United Nations University and was created to develop solutions to
   address issues associated with electronic waste. Some of the most
   eminent players in the fields of Production, Reuse and Recycling of
   Electrical and Electronic Equipment (EEE), government agencies and NGOs
   as well as UN Organisations count themselves among its members. StEP
   encourages the collaboration of all stakeholders connected with
   e-waste, emphasizing a holistic, scientific yet applicable approach to
   the problem.:^[25]

Waste electrical and electronic equipment[edit]

   The European Commission (EC) of the EU has classified waste electrical
   and electronic equipment (WEEE) as the waste generated from electrical
   devices and household appliances like refrigerators, televisions, and
   mobile phones and other devices. In 2005 the EU reported total waste of
   9 million tonnes and in 2020 estimates waste of 12 million tonnes. This
   electronic waste with hazardous materials if not managed properly, may
   end up badly affecting our environment and causing fatal health issues.
   Disposing of these materials requires a lot of manpower and properly
   managed facilities. Not only the disposal, manufacturing of these types
   of materials require huge facilities and natural resources (Aluminium,
   gold, copper and silicon, etc), ending up damaging our environment and
   pollution. Considering the impact of WEEE materials make on our
   environment, EU legislation has made two legislations: 1. WEEE
   Directive; 2. RoHS Directive: Directive on usage and restrictions of
   hazardous materials in producing these Electrical and Electronic
   Equipment.

   WEEE Directive: This Directive was implemented in February 2003,
   focusing on recycling electronic waste. This Directive offered many
   electronic waste collection schemes free of charge to the consumers
   (Directive 2002/96/EC [8]). The EC revised this Directive in December
   2008, since this has become the fastest growing waste stream. In August
   2012, the WEEE Directive was rolled out to handle the situation of
   controlling electronic waste and this was implemented on 14 February
   2014 (Directive 2012/19/EU [9]). On 18 April 2017, the EC adopted a
   common principle of carrying out research and implementing a new
   regulation to monitor the amount of WEEE. It requires each member state
   to monitor and report their national market data. - Annex III to the
   WEEE Directive (Directive 2012/19/EU): Re-examination of the timelines
   for waste collection and setting up individual targets (Report [10]).

   WEEE Legislation: - On 4 July 2012, the EC passed legislation on WEEE
   (Directive 2012/19/EU [11]). To know more about the progress in
   adopting the Directive 2012/19/EU (Progress [12]). - On 15 February
   2014, the EC revised the Directive. To know more about the old
   Directive 2002/96/EC, see (Report [13]).

   RoHS Directive: In 2003, the EC not only implemented legislation on
   waste collection but also on the alternative use of hazardous materials
   (Cadmium, mercury, flammable materials, polybrominated biphenyls, lead
   and polybrominated diphenyl ethers) used in the production of
   electronic and electric equipment (RoHS Directive 2002/95/EC [14]).
   This Directive was again revised in December 2008 and later again in
   January 2013 (RoHS recast Directive 2011/65/EU [15]). In 2017, the EC
   has made adjustment to the existing Directive considering the impact
   assessment [16] and adopted to a new legislative proposal [17] (RoHS 2
   scope review [18]). On 21 November 2017, the European Parliament and
   Council has published this legislation amending the RoHS 2 Directive in
   their official journal [19].

European Commission legislation on batteries and accumulators (Batteries
Directive)[edit]

   Each year, the EU reports nearly 800 000 tons of batteries from
   automotive industry, industrial batteries of around 190 000 tons and
   consumer batteries around 160 000 tons entering the Europe region.
   These batteries are one of the most commonly used products in household
   appliances and other battery powered products in our day-to-day life.
   The important issue to look into is how this battery waste is collected
   and recycled properly, which has the consequences of resulting in
   hazardous materials release into the environment and water resources.
   Generally, many parts of these batteries and accumulators / capacitors
   can be recycled without releasing these hazardous materials release
   into our environment and contaminating our natural resources. The EC
   has rolled out a new Directive to control the waste from the batteries
   and accumulators known as `Batteries Directive'[20] aiming to improve
   the collecting and recycling process of the battery waste and control
   the impact of battery waste on our environment. This Directive also
   supervises and administers the internal market by implementing required
   measures. This Directive restricts the production and marketing of
   batteries and accumulators which contains hazardous materials and are
   harmful to the environment, difficult to collect and recycle them.
   Batteries Directive [21] targets on the collection, recycling and other
   recycling activities of batteries and accumulators, also approving
   labels to the batteries which are environment neutral. On 10 December
   2020, The EC has proposed a new regulation (Batteries Regulation [22])
   on the batteries waste which aims to make sure that batteries entering
   the European market are recyclable, sustainable and non-hazardous
   (Press release [23]).

   Legislation: In 2006, the EC has adopted the Batteries Directive and
   revised it in 2013. - On 6 September 2006, the European Parliament and
   European Council have launched Directives in waste from Batteries and
   accumulators (Directive 2006/66/EC [24]). - Overview of Batteries and
   accumulators Legislation [25]

   Evaluation of Directive 2006/66/EC (Batteries Directive): Revising
   Directives could be based on the Evaluation [26] process, considering
   the fact of the increase in the usage of batteries with an increase in
   the multiple communication technologies, household appliances and other
   small battery-powered products. The increase in the demand of renewable
   energies and recycling of the products has also led to an initiative
   `European Batteries Alliance (EBA)' which aims to supervise the
   complete value chain of production of more improved batteries and
   accumulators within Europe under this new policy act. Though the
   adoption of the Evaluation [27] process has been broadly accepted, few
   concerns rose particularly managing and monitoring the use of hazardous
   materials in the production of batteries, collection of the battery
   waste, recycling of the battery waste within the Directives. The
   evaluation process has definitely gave good results in the areas like
   controlling the environmental damage, increasing the awareness of
   recycling, reusable batteries and also improving the efficiency of the
   internal markets.

   However, there are few limitations in the implementations of the
   Batteries Directive in the process of collecting batteries waste and
   recovering the usable materials from them. The evaluation process
   throws some light on the gap in this process of implementation and
   collaborate technical aspects in the process and new ways to use makes
   it more difficult to implement and this Directive maintains the balance
   with technological advancements. The EC's regulations and guidelines
   has made the evaluation process more impactful in a positive way. The
   participation of number of stakeholders in the evaluation process who
   are invited and asked to provide their views and ideas to improve the
   process of evaluation and information gathering. On 14 March 2018,
   stakeholders and members of the association participated to provide
   information about their findings, support and increase the process of
   Evaluation Roadmap [28].

European Union regulations on e-waste[edit]

   The European Union (EU) has addressed the e-waste issue by adopting
   several directives. In 2011 an amendment was made to a 2003 Directive
   2002/95/EC regarding restriction of the use of hazardous materials in
   the planning and manufacturing process in the EEE. In the 2011
   Directive, 2011/65/EU it was stated as the motivation for more specific
   restriction on the usage of hazardous materials in the planning and
   manufacturing process of electronic and electrical devices as there was
   a disparity of the EU Member State laws and the need arose to set forth
   rules to protect human health and for the environmentally sound
   recovery and disposal of WEEE. (2011/65/EU, (2)) The Directive lists
   several substances subject to restriction. The Directive states
   restricted substances for maximum concentration values tolerated by
   weight in homogeneous materials are the following: lead (0.1%); mercury
   (0.1%), cadmium (0.1%), hexavalent chromium (0.1%), polybrominated
   biphenyls (PBB) (0.1%) and polybrominated diphenyl ethers (PBDE)
   (o,1 %). If technologically feasible and substitution is available, the
   usage of substitution is required.

   There are, however, exemptions in the case in which substitution is not
   possible from the scientific and technical point of view. The allowance
   and duration of the substitutions should take into account the
   availability of the substitute and the socioeconomic impact of the
   substitute. (2011/65/EU, (18))

   EU Directive 2012/19/EU regulates WEEE and lays down measures to
   safeguard the ecosystem and human health by inhibiting or shortening
   the impact of the generation and management of waste of WEEE.
   (2012/19/EU, (1)) The Directive takes a specific approach to the
   product design of EEE. It states in Article 4 that Member States are
   under the constraint to expedite the kind of model and manufacturing
   process as well as cooperation between producers and recyclers as to
   facilitate re-use, dismantling and recovery of WEEE, its components,
   and materials. (2012/19/EU, (4)) The Member States should create
   measures to make sure the producers of EEE use eco-design, meaning that
   the type of manufacturing process is used that would not restrict later
   re-use of WEEE. The Directive also gives Member States the obligation
   to ensure a separate collection and transportation of different WEEE.
   Article 8 lays out the requirements of the proper treatment of WEEE.
   The base minimum of proper treatment that is required for every WEEE is
   the removal of all liquids. The recovery targets set are seen in the
   following figures.

   Bu the Annex I of Directive 2012/19/EU the categories of EEE covered
   are as follows:
    1. Large household appliances
    2. Small household appliances
    3. IT and telecommunications equipment
    4. Consumer equipment and photovoltaic panels
    5. Lighting equipment
    6. Electrical and electronic tools (with the exception of large-scale
       stationary industrial tools)
    7. Toys, leisure and sports equipment
    8. Medical devices (with the exception of all implanted and infected
       products)
    9. Monitoring and control instruments
   10. Autonomic dispensers

   Minimum recovery targets referred in Directive 2012/19/EU starting from
   15 August 2018:

   WEEE falling within category 1 or 10 of Annex I

   - 85% shall be recovered, and 80% shall be prepared for re-use and
   recycled;

   WEEE falling within category 3 or 4 of Annex I

   - 80% shall be recovered, and 70% shall be prepared for re-use and
   recycled;

   WEEE falling within category 2, 5, 6, 7, 8 or 9 of Annex I

   -75% shall be recovered, and 55% shall be prepared for re-use and
   recycled;

   For gas and discharged lamps, 80% shall be recycled.

   In 2021, the European Commission proposed the implementation of a
   standardization - for iterations of USB-C - of phone charger products
   after commissioning two impact assessment studies and a technology
   analysis study. Regulations like this may reduce electronic waste by
   small but significant amounts as well as, in this case, increase
   device-interoperability, convergence and convenience for consumers
   while decreasing resource-needs and
   redundancy.^[26]^[27]^[28]^[additional citation(s) needed]

Global trade issues[edit]

   See also: Global Waste Trade and Electronic waste by country
   Electronic waste is often exported to developing countries.
   4.5-volt, D, C, AA, AAA, AAAA, A23, 9-volt, CR2032, and LR44 cells are
   all recyclable in most countries.
   The E-waste centre of Agbogbloshie, Ghana, where electronic waste is
   burnt and disassembled with no safety or environmental considerations.

   One theory is that increased regulation of electronic wastes and
   concern over the environmental harm in nature economies creates an
   economic disincentive to remove residues prior to export. Critics of
   trade in used electronics maintain that it is still too easy for
   brokers calling themselves recyclers to export unscreened electronic
   waste to developing countries, such as China,^[37] 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 have become toxic dump yards of e-waste.
   Developing countries receiving foreign e-waste often go further to
   repair and recycle forsaken equipment.^[38] Yet still 90% of e-waste
   ended up in landfills in developing countries in 2003.^[38] Proponents
   of international trade point to the success of fair trade programs in
   other industries, where cooperation has led to creation of sustainable
   jobs and can bring affordable technology in countries where repair and
   reuse rates are higher.

   Defenders of the trade^[who?] in used electronics say that extraction
   of metals from virgin mining has been shifted to developing countries.
   Recycling of copper, silver, gold, and other materials from discarded
   electronic devices is considered better for the environment than
   mining. 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 labour standards, cheap labour, and the relatively high value of
   recovered raw materials lead to a transfer of pollution-generating
   activities, such as smelting of copper wire. Electronic waste is often
   sent to various African and Asian countries such as China, Malaysia,
   India, and Kenya for processing, sometimes illegally. Many surplus
   laptops are routed to developing nations as "dumping grounds for
   e-waste".^[39]

   Because the United States has not ratified the Basel Convention or its
   Ban Amendment, and has few domestic federal 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.^[40]^[41]^[42]^[43] 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".^[44]

Trade[edit]

   Sacks of mobile phones in Agbogbloshie, Ghana.

   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
   re-manufacturing, 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.^[45]

   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 non-valuable 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.^[43]

   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.^[46] Concern over exports of
   electronic waste were raised in press reports in India,^[47]^[48]
   Ghana,^[49]^[50]^[51] Cote d'Ivoire,^[52] and Nigeria.^[53]

   The research that was undertaken by the Countering WEEE Illegal Trade
   (CWIT) project, funded by European Commission, found that in Europe
   only 35% (3.3 million tons) of all the e-waste discarded in 2012 ended
   up in the officially reported amounts of collection and recycling
   systems. The other 65% (6.15 million tons) was either:
     * Exported (1.5 million tons),
     * Recycled under non-compliant conditions in Europe (3.15 million
       tons),
     * Scavenged for valuable parts (750,000 tons), or
     * Simply thrown in waste bins (750,000 tons).^[54]

Guiyu[edit]

   Main articles: Electronic waste in China and Electronic waste in Guiyu

   Guiyu in the Guangdong region of China is a massive electronic waste
   processing community.^[40]^[55]^[56] It is often referred to as the
   "e-waste capital of the world." Traditionally, Guiyu was an
   agricultural community; however, in the mid-1990s it transformed into
   an e-waste recycling center involving over 75% of the local households
   and an additional 100,000 migrant workers.^[57] Thousands of individual
   workshops employ laborers to snip cables, pry chips from circuit
   boards, grind plastic computer cases into particles, and dip circuit
   boards in acid baths to dissolve the precious metals. Others work to
   strip insulation from all wiring in an attempt to salvage tiny amounts
   of copper wire.^[58] Uncontrolled burning, disassembly, and disposal
   has led to a number of environmental problems such as groundwater
   contamination, atmospheric pollution, and water pollution either by
   immediate discharge or from 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.

   Six of the many villages in Guiyu specialize in circuit-board
   disassembly, seven in plastics and metals reprocessing, and two in wire
   and cable disassembly. Greenpeace, an environmental group, sampled
   dust, soil, river sediment, and groundwater in Guiyu. They found very
   high levels of toxic heavy metals and organic contaminants in both
   places.^[59] Lai Yun, a campaigner for the group found "over 10
   poisonous metals, such as lead, mercury, and cadmium."

   Guiyu is only one example of digital dumps but similar places can be
   found across the world in Nigeria, Ghana, and India.^[60]

Other informal e-waste recycling sites[edit]

   A pile of discarded TVs and computer monitors.

   Guiyu is likely one of the oldest and largest informal e-waste
   recycling sites in the world; however, there are many sites worldwide,
   including India, Ghana (Agbogbloshie), Nigeria, and the Philippines.
   There are a handful of studies that describe exposure levels in e-waste
   workers, the community, and the environment. For example, locals and
   migrant workers in Delhi, a northern union territory of India, scavenge
   discarded computer equipment and extract base metals using toxic,
   unsafe methods.^[61] Bangalore, located in southern India, is often
   referred as the "Silicon Valley of India" and has a growing informal
   e-waste recycling sector.^[62]^[63] A study found that e-waste workers
   in the slum community had higher levels of V, Cr, Mn, Mo, Sn, Tl, and
   Pb than workers at an e-waste recycling facility.^[62]

Cryptocurrency e-waste[edit]

   Bitcoin mining has also contributed to higher amounts in electronic
   waste, as it has become an increasingly popular form of currency in
   global trade. According to Alex de Vries and Christian Stoll, the
   average bitcoin transaction yields 272 grams of electronic waste and
   has generated approximately 112.5 million grams of waste in 2020
   alone.^[64] Other estimates indicate that the Bitcoin network discards
   as much "small IT and telecommunication equipment waste produced by a
   country like the Netherlands," totalling to 30.7 metric kilotons every
   year.^[64] Furthermore, the rate at which Bitcoin disposes of its waste
   exceeds that of major financial organizations such as VISA, which
   produces 40 grams of waste for every 100,000 transactions.^[65]

   A major point of concern is the rapid turnover of technology in the
   Bitcoin industry which results in such high levels of e-waste. This can
   be attributed to the proof-of-work principle Bitcoin employs where
   miners receive currency as a reward for being the first to decode the
   hashes that encode its blockchain.^[66] As such, miners are encouraged
   to compete with one another to decode the hash first.^[66] However,
   computing these hashes requires massive computing power which, in
   effect, drives miners to obtain rigs with the highest processing power
   possible. In an attempt to achieve this, miners increase the processing
   power in their rigs by purchasing more advanced computer chips.^[66]

   According to Koomey's Law, efficiency in computer chips doubles every
   1.5 years,^[67] meaning that miners are incentivized to purchase new
   chips to keep up with competing miners even though the older chips are
   still functional. In some cases, miners even discard their chips
   earlier than this timeframe for the sake of profitability.^[64]
   However, this leads to a significant build up in waste, as outdated
   application-specific integrated circuits (ASIC computer chips) cannot
   be reused or repurposed.^[66] Most computer chips miners currently use
   are ASIC chips, whose sole function is to mine bitcoin, rendering them
   useless for other cryptocurrencies or operation in any other piece of
   technology.^[66] Therefore, outdated ASIC chips can only be disposed of
   since they are unable to be repurposed.

   Bitcoin's e-waste problem is further exacerbated by the fact that many
   countries and corporations lack recycling programs for ASIC chips.^[64]
   Developing a recycling infrastructure for bitcoin mining may prove to
   be beneficial, though, as the aluminum heat sinks and metal casings in
   ASIC chips can be recycled into new technology.^[64] Much of this
   responsibility falls onto Bitmain, the leading manufacturer of Bitcoin,
   which currently lacks the infrastructure to recycle waste from bitcoin
   mining.^[64] Without such programs, much of bitcoin waste ends up in
   landfill along with 83.6% of the global total of e-waste.^[64]

   Many argue for relinquishing the proof-of-work model altogether in
   favour of the proof-of-stake one. This model selects one miner to
   validate the transactions in the blockchain, rather than have all
   miners competing for it.^[68] With no competition, the processing speed
   of miners' rigs would not matter.^[64] Any device could be used for
   validating the blockchain, so there would be no incentive to use
   single-use ASIC chips or continually purchase new and dispose of old
   ones.^[64]^[68]

Environmental impact[edit]

   Old keyboards and a mouse.

   A recent study about the rising electronic pollution in the USA
   revealed that the average computer screen has five to eight pounds or
   more of lead representing 40 percent of all the lead in US landfills.
   All these toxins are persistent, bioaccumulative toxins (PBTs) that
   create environmental and health risks when computers are incinerated,
   put in landfills or melted down. The emission of fumes, gases, and
   particulate matter into the air, the discharge of liquid waste into
   water and drainage systems, and the disposal of hazardous wastes
   contribute to environmental degradation.^[69] The processes of
   dismantling and disposing of electronic waste in developing countries
   led to a number of environmental impacts as illustrated in the graphic.
   Liquid and atmospheric releases end up in bodies of water, groundwater,
   soil, and air and therefore in land and sea animals - both domesticated
   and wild, in crops eaten by both animals and human, and in drinking
   water.^[70]

   One study of environmental effects in Guiyu, China found the
   following:^[9]
     * Airborne dioxins - one type found at 100 times levels previously
       measured
     * Levels of carcinogens in duck ponds and rice paddies exceeded
       international standards for agricultural areas and cadmium, copper,
       nickel, and lead levels in rice paddies were above international
       standards
     * Heavy metals found in road dust - lead over 300 times that of a
       control village's road dust and copper over 100 times

   The Agbogbloshie area of Ghana, where about 40,000 people live,
   provides an example of how e-waste contamination can pervade the daily
   lives of nearly all residents. Into this area--one of the largest
   informal e-waste dumping and processing sites in Africa--about 215,000
   tons of secondhand consumer electronics, primarily from Western Europe,
   are imported annually. Because this region has considerable overlap
   among industrial, commercial, and residential zones, Pure Earth
   (formerly Blacksmith Institute) has ranked Agbogbloshie as one of the
   world's 10 worst toxic threats (Blacksmith Institute 2013).^[71]

   A separate study at the Agbogbloshie e-waste dump, Ghana found a
   presence of lead levels as high as 18,125 ppm in the soil.^[72] US EPA
   standard for lead in soil in play areas is 400 ppm and 1200 ppm for
   non-play areas.^[73] Scrap workers at the Agbogbloshie e-waste dump
   regularly burn electronic components and auto harness wires for copper
   recovery,^[74] releasing toxic chemicals like lead, dioxins and
   furans^[75] into the environment.

   Researchers such as Brett Robinson, a professor of soil and physical
   sciences at Lincoln University in New Zealand, warn that wind patterns
   in Southeast China disperse toxic particles released by open-air
   burning across the Pearl River Delta Region, home to 45 million people.
   In this way, toxic chemicals from e-waste enter the "soil-crop-food
   pathway," one of the most significant routes for heavy metals' exposure
   to humans. These chemicals are not biodegradable-- they persist in the
   environment for long periods of time, increasing exposure risk.^[76]

   In the agricultural district of Chachoengsao, in the east of Bangkok,
   local villagers had lost their main water source as a result of e-waste
   dumping. The cassava fields were transformed in late 2017, when a
   nearby Chinese-run factory started bringing in foreign e-waste items
   such as crushed computers, circuit boards and cables for recycling to
   mine the electronics for valuable metal components like copper, silver
   and gold. But the items also contain lead, cadmium and mercury, which
   are highly toxic if mishandled during processing. Apart from feeling
   faint from noxious fumes emitted during processing, a local claimed the
   factory has also contaminated her water. "When it was raining, the
   water went through the pile of waste and passed our house and went into
   the soil and water system. Water tests conducted in the province by
   environmental group Earth and the local government both found toxic
   levels of iron, manganese, lead, nickel and in some cases arsenic and
   cadmium. "The communities observed when they used water from the
   shallow well, there was some development of skin disease or there are
   foul smells," founder of Earth, Penchom Saetang said. "This is proof,
   that it is true, as the communities suspected, there are problems
   happening to their water sources."^[77]

   electronic waste components^[78]

   Depending on the age and type of the discarded item, the chemical
   composition of E-waste may vary. Most E-waste are composed of a mixture
   of metals like Cu, Al and Fe. They might be attached to, covered with
   or even mixed with various types of plastics and ceramics. E-waste has
   a horrible effect on the environment and it is important to dispose it
   with an R2 certifies recycling facility.^[79]

Research[edit]

   In May 2020, a scientific study was conducted in China that
   investigated the occurrence and distribution of traditional and novel
   classes of contaminants, including chlorinated, brominated, and mixed
   halogenated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs, PBDD/Fs,
   PXDD/Fs), polybrominated diphenyl ethers (PBDEs), polychlorinated
   biphenyls (PCBs) and polyhalogenated carbazoles (PHCZs) in soil from an
   e-waste disposal site in Hangzhou (which has been in operation since
   2009 and has a treatment capacity of 19.6 Wt/a). While the study area
   has only one formal emission source, the broader industrial zone has a
   number of metal recovery and reprocessing plants as well as heavy
   traffic on adjacent motorways where normal and heavy-duty devices are
   used. The maximum concentrations of the target halogenated organic
   compounds HOCs were 0.1-1.5 km away from the main source and overall
   detected levels of HOCs were generally lower than those reported
   globally. The study proved what researchers have warned, i. e. on
   highways with heavy traffic, especially those serving diesel powered
   vehicles, exhaust emissions are larger sources of dioxins than
   stationary sources. When assessing the environmental and health impacts
   of chemical compounds, especially PBDD/Fs and PXDD/Fs, the
   compositional complexity of soil and long period weather conditions
   like rain and downwind have to be taken into account. Further
   investigations are necessary to build up a common understanding and
   methods for assessing e-waste impacts.^[80]

Information security[edit]

   Discarded data processing equipment may still contain readable data
   that may be considered sensitive to the previous users of the device. A
   recycling plan for such equipment can support information security by
   ensuring proper steps are followed to erase the sensitive information.
   This may include such steps as re-formatting of storage media and
   overwriting with random data to make data unrecoverable, or even
   physical destruction of media by shredding and incineration to ensure
   all data is obliterated. For example, on many operating systems
   deleting a file may still leave the physical data file intact on the
   media, allowing data retrieval by routine methods.

Recycling[edit]

   recycling
   Computer monitors are typically packed into low stacks on wooden
   pallets for recycling and then shrink-wrapped.

   Recycling is an essential element of e-waste management. Properly
   carried out, it should greatly reduce the leakage of toxic materials
   into the environment and militate against the exhaustion of natural
   resources. However, it does need to be encouraged by local authorities
   and through community education. Less than 20% of e-waste is formally
   recycled, with 80% either ending up in landfill or being informally
   recycled - much of it by hand in developing countries, exposing workers
   to hazardous and carcinogenic substances such as mercury, lead and
   cadmium.^[81]

   One of the major challenges is recycling the printed circuit boards
   from electronic waste. The circuit boards contain such precious metals
   as gold, silver, platinum, etc. and such base metals as copper, iron,
   aluminum, etc. One way e-waste is processed is by melting circuit
   boards, burning cable sheathing to recover copper wire and open- pit
   acid leaching for separating metals of value.^[9] 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,^[82] and some
   other methods are still under investigation. Properly disposing of or
   reusing electronics can help prevent health problems, reduce
   greenhouse-gas emissions, and create jobs.^[83]

Consumer awareness efforts[edit]

   A campaign to promote e-waste recycling in Ghana.

   The U.S. Environmental Protection Agency encourages electronic
   recyclers to become certified by demonstrating to an accredited,
   independent third party auditor that they meet specific standards to
   safely recycle and manage electronics. This should work so as to ensure
   the highest environmental standards are being maintained. Two
   certifications for electronic recyclers currently exist and are
   endorsed by the EPA. Customers are encouraged to choose certified
   electronics recyclers. Responsible electronics recycling reduces
   environmental and human health impacts, increases the use of reusable
   and refurbished equipment and reduces energy use while conserving
   limited resources. The two EPA-endorsed certification programs are
   Responsible Recyclers Practices (R2) and E-Stewards. Certified
   companies ensure they are meeting strict environmental standards which
   maximize reuse and recycling, minimize exposure to human health or the
   environment, ensure safe management of materials and require
   destruction of all data used on electronics.^[84] Certified electronics
   recyclers have demonstrated through audits and other means that they
   continually meet specific high environmental standards and safely
   manage used electronics. Once certified, the recycler is held to the
   particular standard by continual oversight by the independent
   accredited certifying body. A certification board accredits and
   oversees certifying bodies to ensure that they meet specific
   responsibilities and are competent to audit and provide
   certification.^[85]

   Some U.S. retailers offer opportunities for consumer recycling of
   discarded electronic devices.^[86]^[87] In the US, the Consumer
   Electronics Association (CEA) urges consumers to dispose properly of
   end-of-life electronics through its recycling locator. This list only
   includes manufacturer and retailer programs that use the strictest
   standards and third-party certified recycling locations, to provide
   consumers assurance that their products will be recycled safely and
   responsibly. CEA research has found that 58 percent of consumers know
   where to take their end-of-life electronics, and the electronics
   industry would very much like to see that level of awareness increase.
   Consumer electronics manufacturers and retailers sponsor or operate
   more than 5,000 recycling locations nationwide and have vowed to
   recycle one billion pounds annually by 2016,^[88] a sharp increase from
   300 million pounds industry recycled in 2010.

   The Sustainable Materials Management (SMM) Electronic Challenge was
   created by the United States Environmental Protection Agency (EPA) in
   2012.^[89] Participants of the Challenge are manufacturers of
   electronics and electronic retailers. These companies collect
   end-of-life (EOL) electronics at various locations and send them to a
   certified, third-party recycler. Program participants are then able
   publicly promote and report 100% responsible recycling for their
   companies.^[90] The Electronics TakeBack Coalition (ETBC)^[91] is a
   campaign aimed at protecting human health and limiting environmental
   effects where electronics are being produced, used, and discarded. The
   ETBC aims to place responsibility for disposal of technology products
   on electronic manufacturers and brand owners, primarily through
   community promotions and legal enforcement initiatives. It provides
   recommendations for consumer recycling and a list of recyclers judged
   environmentally responsible.^[92] While there have been major benefits
   from the rise in recycling and waste collection created by producers
   and consumers, such as valuable materials being recovered and kept away
   from landfill and incineration, there are still many problems present
   with the EPR system including "how to ensure proper enforcement of
   recycling standards, what to do about waste with positive net value,
   and the role of competition," (Kunz et al.). Many stakeholders agreed
   there needs to be a higher standard of accountability and efficiency to
   improve the systems of recycling everywhere, as well as the growing
   amount of waste being an opportunity more so than downfall since it
   gives us more chances to create an efficient system. To make recycling
   competition more cost-effective, the producers agreed that there needs
   to be a higher drive for competition because it allows them to have a
   wider range of producer responsibility organizations to choose from for
   e-waste recycling.^[93]

   The Certified Electronics Recycler program^[94] for electronic
   recyclers is a comprehensive, integrated management system standard
   that incorporates key operational and continual improvement elements
   for quality, environmental and health and safety performance. The
   grassroots Silicon Valley Toxics Coalition promotes human health and
   addresses environmental justice problems resulting from toxins in
   technologies. The World Reuse, Repair, and Recycling Association
   (wr3a.org) is an organization dedicated to improving the quality of
   exported electronics, encouraging better recycling standards in
   importing countries, and improving practices through "Fair Trade"
   principles. Take Back My TV^[95] is a project of The Electronics
   TakeBack Coalition and grades television manufacturers to find out
   which are responsible, in the coalition's view, and which are not.

   There have also been efforts to raise awareness of the potentially
   hazardous conditions of the dismantling of e-waste in American prisons.
   The Silicon Valley Toxics Coalition, prisoner-rights activists, and
   environmental groups released a Toxic Sweatshops report that details
   how prison labor is being used to handle e-waste, resulting in health
   consequences among the workers.^[96] These groups allege that, since
   prisons do not have adequate safety standards, inmates are dismantling
   the products under unhealthy and unsafe conditions.^[97]

Processing techniques[edit]

   Recycling the lead from batteries.

   In many 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.^[98]^[99] The
   advantages of this process are the human worker'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,^[100] 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".^[101] 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.

   In early November 2021, the U.S. of Georgia announced a joint effort
   with Igneo Technologies to build an $85 million large electronics
   recycling plant in the Port of Savannah. The project will focus on
   lower-value, plastics-heavy devices in the waste stream using multiple
   shredders and furnaces using pyrolysis technology.^[102]

Benefits of recycling[edit]

   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.^[103] Another benefit of recycling
   e-waste is that many of the materials can be recycled and re-used
   again. Materials that can be recycled include "ferrous (iron-based) and
   non-ferrous metals, glass, and various types of plastic." "Non-ferrous
   metals, mainly aluminum and copper can all be re-smelted and
   re-manufactured. Ferrous metals such as steel and iron also can be
   re-used."^[104] Due to the recent surge in popularity in 3D printing,
   certain 3D printers have been designed (FDM variety) to produce waste
   that can be easily recycled which decreases the amount of harmful
   pollutants in the atmosphere.^[105] The excess plastic from these
   printers that comes out as a byproduct can also be reused to create new
   3D printed creations.^[106]

   Benefits of recycling are extended when responsible recycling methods
   are used. In the U.S., responsible recycling aims to minimize the
   dangers to human health and the environment that disposed and
   dismantled electronics can create. Responsible recycling ensures best
   management practices of the electronics being recycled, worker health
   and safety, and consideration for the environment locally and
   abroad.^[107] In Europe, metals that are recycled are returned to
   companies of origin at a reduced cost.^[108] Through a committed
   recycling system, manufacturers in Japan have been pushed to make their
   products more sustainable. Since many companies were responsible for
   the recycling of their own products, this imposed responsibility on
   manufacturers requiring many to redesign their infrastructure. As a
   result, manufacturers in Japan have the added option to sell the
   recycled metals.^[109]

   Improper management of e-waste is resulting in a significant loss of
   scarce and valuable raw materials, such as gold, platinum, cobalt and
   rare earth elements. As much as 7% of the world's gold may currently be
   contained in e-waste, with 100 times more gold in a tonne of e-waste
   than in a tonne of gold ore.^[81]

Repair as waste reduction method[edit]

   There are several ways to curb the environmental hazards arising from
   the recycling of electronic waste. One of the factors which exacerbate
   the e-waste problem is the diminishing lifetime of many electrical and
   electronic goods. There are two drivers (in particular) for this trend.
   On the one hand, consumer demand for low cost products militates
   against product quality and results in short product lifetimes.^[110]
   On the other, manufacturers in some sectors encourage a regular upgrade
   cycle, and may even enforce it though restricted availability of spare
   parts, service manuals and software updates, or through planned
   obsolescence.

   Consumer dissatisfaction with this state of affairs has led to a
   growing repair movement. Often, this is at a community level such as
   through repair cafes or the "restart parties" promoted by the Restart
   Project.^[111]

   The Right to Repair is spearheaded in the US by farmers dissatisfied
   with non-availability of service information, specialised tools and
   spare parts for their high-tech farm machinery. But the movement
   extends far beyond farm machinery with, for example, the restricted
   repair options offered by Apple coming in for criticism. Manufacturers
   often counter with safety concerns resulting from unauthorised repairs
   and modifications.^[112]

   An easy method of reducing electronic waste footprint is to sell or
   donate electronic gadgets, rather than dispose of them. Improperly
   disposed e-waste is becoming more and more hazardous, especially as the
   sheer volume of e-waste increases. For this reason, large brands like
   Apple, Samsung, and others have started giving options to customers to
   recycle old electronics. Recycling allows the expensive electronic
   parts inside to be reused. This may save significant energy and reduce
   the need for mining of additional raw resources, or manufacture of new
   components. Electronic recycling programs may be found locally in many
   areas with a simple online search; for example, by searching "recycle
   electronics" along with the city or area name.

   Cloud services have proven to be useful in storing data, which is then
   accessible from anywhere in the world without the need to carry storage
   devices. Cloud storage also allows for large storage, at low cost. This
   offers convenience, while reducing the need for manufacture of new
   storage devices, thus curbing the amount of e-waste generated.^[113]

Electronic waste classification[edit]

   The market has a lot of different types of electrical products. To
   categorize these products, it is necessary to group them into sensible
   and practical categories. Classification of the products may even help
   to determine the process to be used for disposal of the product. Making
   the classifications, in general, is helping to describe e-waste.
   Classifications has not defined special details, for example when they
   do not pose a threat to the environment. On the other hand,
   classifications should not be too aggregated because of countries
   differences in interpretation.^[114]^[114] The UNU-KEYs system closely
   follows the harmonized statistical (HS) coding. It is an international
   nomenclature which is an integrated system to allow classify common
   basis for customs purposes.^[114]

Electronic waste substances[edit]

   Several sizes of button and coin cell with 2 9v batteries as a size
   comparison. They are all recycled in many countries since they often
   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 jewellery.
   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.^[115] 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,^[116] 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.
   The following are ordinary applications:

Hazardous[edit]

   CAPTION: Hazardous waste material from e-waste

   E-Waste Component Electric Appliances in which they are found Adverse
   Health Effects
   Americium The radioactive source in smoke alarms. It is known to be
   carcinogenic.^[117]
   Lead Solder, CRT monitor glass, lead-acid batteries, some formulations
   of PVC. A typical 15-inch cathode ray tube may contain 1.5 pounds of
   lead,^[4] but other CRTs have been estimated as having up to 8 pounds
   of lead. Adverse effects of lead exposure include impaired cognitive
   function, behavioral disturbances, attention deficits, hyperactivity,
   conduct problems, and lower IQ.^[118] These effects are most damaging
   to children whose developing nervous systems are very susceptible to
   damage caused by lead, cadmium, and mercury.^[119]
   Mercury Found in fluorescent tubes (numerous applications), tilt
   switches (mechanical doorbells, thermostats),^[120] and ccfl backlights
   in flat screen monitors. Health effects include sensory impairment,
   dermatitis, memory loss, and muscle weakness. Exposure in-utero causes
   fetal deficits in motor function, attention, and verbal domains.^[118]
   Environmental effects in animals include death, reduced fertility, and
   slower growth and development.
   Cadmium Found in light-sensitive resistors, corrosion-resistant alloys
   for marine and aviation environments, and nickel-cadmium batteries. The
   most common form of cadmium is found in Nickel-cadmium rechargeable
   batteries. These batteries tend to contain between 6 and 18% cadmium.
   The sale of Nickel-Cadmium batteries has been banned in the EU except
   for medical use. When not properly recycled it can leach into the soil,
   harming microorganisms and disrupting the soil ecosystem. Exposure is
   caused by proximity to hazardous waste sites and factories and workers
   in the metal refining industry. The inhalation of cadmium can cause
   severe damage to the lungs and is also known to cause kidney
   damage.^[121] Cadmium is also associated with deficits in cognition,
   learning, behavior, and neuromotor skills in children.^[118]
   Hexavalent chromium Used in metal coatings to protect from corrosion. A
   known carcinogen after occupational inhalation exposure.^[118]

   There is also evidence of cytotoxic and genotoxic effects of some
   chemicals, which have been shown to inhibit cell proliferation, cause
   cell membrane lesion, cause DNA single-strand breaks, and elevate
   Reactive Oxygen Species (ROS) levels.^[122]
   Sulfur Found in lead-acid batteries. Health effects include liver
   damage, kidney damage, heart damage, eye and throat irritation. When
   released into the environment, it can create sulfuric acid through
   sulfur dioxide.
   Brominated Flame Retardants (BFRs) Used as flame retardants in plastics
   in most electronics. Includes PBBs, PBDE, DecaBDE, OctaBDE, PentaBDE.
   Health effects include impaired development of the nervous system,
   thyroid problems, liver problems.^[123] Environmental effects: similar
   effects as in animals as humans. PBBs were banned from 1973 to 1977 on.
   PCBs were banned during the 1980s.
   Perfluorooctanoic acid (PFOA) Used as an antistatic additive in
   industrial applications and found in electronics, also found in
   non-stick cookware (PTFE). PFOAs are formed synthetically through
   environmental degradation. Studies in mice have found the following
   health effects: Hepatotoxicity, developmental toxicity, immunotoxicity,
   hormonal effects and carcinogenic effects. Studies have found increased
   maternal PFOA levels to be associated with an increased risk of
   spontaneous abortion (miscarriage) and stillbirth. Increased maternal
   levels of PFOA are also associated with decreases in mean gestational
   age (preterm birth), mean birth weight (low birth weight), mean birth
   length (small for gestational age), and mean APGAR score.^[124]
   Beryllium oxide Filler in some thermal interface materials such as
   thermal grease used on heatsinks for CPUs and power transistors,^[125]
   magnetrons, X-ray-transparent ceramic windows, heat transfer fins in
   vacuum tubes, and gas lasers. Occupational exposures associated with
   lung cancer, other common adverse health effects are beryllium
   sensitization, chronic beryllium disease, and acute beryllium
   disease.^[126]
   Polyvinyl chloride (PVC) Commonly found in electronics and is typically
   used as insulation for electrical cables.^[127] In the manufacturing
   phase, toxic and hazardous raw material, including dioxins are
   released. PVC such as chlorine tend to bioaccumulate.^[128] Over time,
   the compounds that contain chlorine can become pollutants in the air,
   water, and soil. This poses a problem as human and animals can ingest
   them. Additionally, exposure to toxins can result in reproductive and
   developmental health effects.^[129]

Human health and safety[edit]

Residents living near recycling sites[edit]

   Residents living around the e-waste recycling sites, even if they do
   not involve in e-waste recycling activities, can also face the
   environmental exposure due to the food, water, and environmental
   contamination caused by e-waste, because they can easily contact to
   e-waste contaminated air, water, soil, dust, and food sources. In
   general, there are three main exposure pathways: inhalation, ingestion,
   and dermal contact.^[131]

   Studies show that people living around e-waste recycling sites have a
   higher daily intake of heavy metals and a more serious body burden.
   Potential health risks include mental health, impaired cognitive
   function, and general physical health damage.^[132](See also Electronic
   waste#Hazardous) DNA damage was also found more prevalent in all the
   e-waste exposed populations (i.e. adults, children, and neonates) than
   the populations in the control area.^[132] DNA breaks can increase the
   likelihood of wrong replication and thus mutation, as well as lead to
   cancer if the damage is to a tumor suppressor gene .^[122]

Prenatal exposure and neonates' health[edit]

   Prenatal exposure to e-waste has found to have adverse effects on human
   body burden of pollutants of the neonates. In Guiyu, one of the most
   famous e-waste recycling sites in China, it was found that increased
   cord blood lead concentration of neonates was associated with parents'
   participation in e-waste recycling processes, as well as how long the
   mothers spent living in Guiyu and in e-waste recycling factories or
   workshops during pregnancy.^[131] Besides, a higher placental
   metallothionein (a small protein marking the exposure of toxic metals)
   was found among neonates from Guiyu as a result of Cd exposure, while
   the higher Cd level in Guiyu's neonates was related to the involvement
   in e-waste recycling of their parents.^[133] High PFOA exposure of
   mothers in Guiyu is related to adverse effect on growth of their
   new-born and the prepotency in this area.^[134]

   Prenatal exposure to informal e-waste recycling can also lead to
   several adverse birth outcomes (still birth, low birth weight, low
   Apgar scores, etc.) and longterm effects such as behavioral and
   learning problems of the neonates in their future life.^[135]

Children[edit]

   Children are especially sensitive to e-waste exposure because of
   several reasons, such as their smaller size, higher metabolism rate,
   larger surface area in relation to their weight, and multiple exposure
   pathways (for example, dermal, hand-to-mouth, and take-home
   exposure).^[136]^[132] They were measured to have an 8-time potential
   health risk compared to the adult e-waste recycling workers.^[132]
   Studies have found significant higher blood lead levels (BLL) and blood
   cadmium levels (BCL) of children living in e-waste recycling area
   compared to those living in control area.^[137]^[138] For example, one
   study found that the average BLL in Guiyu was nearly 1.5 times compared
   to that in the control site (15.3 ug/dL compared to 9.9 ug/dL),^[137]
   while the CDC of the United States has set a reference level for blood
   lead at 5 ug/dL.^[139] The highest concentrations of lead were found in
   the children of parents whose workshop dealt with circuit boards and
   the lowest was among those who recycled plastic.^[137]

   Exposure to e-waste can cause serious health problems to children.
   Children's exposure to developmental neurotoxins containing in e-waste
   such as lead, mercury, cadmium, chromium and PBDEs can lead to a higher
   risk of lower IQ, impaired cognitive function, and other adverse
   effects.^[140] In certain age groups, a decreased lung function of
   children in e-waste recycling sites has been found.^[131] Some studies
   also found associations between children's e-waste exposure and
   impaired coagulation,^[141] hearing loss,^[142] and decreased vaccine
   antibody tilters^[143] in e-waste recycling area.

E-waste recycling workers[edit]

   The complex composition and improper handling of e-waste adversely
   affect human health. A growing body of epidemiological and clinical
   evidence has led to increased concern about the potential threat of
   e-waste to human health, especially in developing countries such as
   India and China. For instance, in terms of health hazards, open burning
   of printed wiring boards increases the concentration of dioxins in the
   surrounding areas. These toxins cause an increased risk of cancer if
   inhaled by workers and local residents. Toxic metals and poison can
   also enter the bloodstream during the manual extraction and collection
   of tiny quantities of precious metals, and workers are continuously
   exposed to poisonous chemicals and fumes of highly concentrated acids.
   Recovering resalable copper by burning insulated wires causes
   neurological disorders, and acute exposure to cadmium, found in
   semiconductors and chip resistors, can damage the kidneys and liver and
   cause bone loss. Long-term exposure to lead on printed circuit boards
   and computer and television screens can damage the central and
   peripheral nervous system and kidneys, and children are more
   susceptible to these harmful effects.^[144]

   The Occupational Safety & Health Administration (OSHA) has summarized
   several potential safety hazards of recycling workers in general, such
   as crushing hazards, hazardous energy released, and toxic metals.^[145]

   CAPTION: Hazards applicable to recycling in general^[145]^[146]

   Hazards Details
   Slips, trips, and falls They can happen during collecting and
   transporting e-wastes.
   Crushing hazards Workers can be stuck or crushed by the machine or the
   e-waste. There can be traffic accidents when transporting e-waste.
   Using machines that have moving parts, such as conveyors and rolling
   machines can also cause crush accidents, leading to amputations,
   crushed fingers or hands.
   Hazardous energy released Unexpected machine startup can cause death or
   injury to workers. This can happen during the installation,
   maintenance, or repair of machines, equipment, processes, or systems.
   Cuts and lacerations Hands or body injuries and eye injuries can occur
   when dismantling e-wastes that have sharp edges.
   Noise Working overtime near loud noises from drilling, hammering, and
   other tools that can make a great noise lead to hearing loss.
   Toxic chemicals (dusts) Burning e-waste to extract metals emits toxic
   chemicals (e.g. PAHs, lead) from e-waste to the air, which can be
   inhaled or ingested by workers at recycling sites. This can lead to
   illness from toxic chemicals.

   OSHA has also specified some chemical components of electronics that
   can potentially do harm to e-recycling workers' health, such as lead,
   mercury, PCBs, asbestos, refractory ceramic fibers (RCFs), and
   radioactive substances.^[145] Besides, in the United States, most of
   these chemical hazards have specific Occupational exposure limits
   (OELs) set by OSHA, National Institute for Occupational Safety and
   Health (NIOSH), and American Conference of Governmental Industrial
   Hygienists (ACGIH).

Informal and formal industries[edit]

   Informal e-recycling industry refers to small e-waste recycling
   workshops with few (if any) automatic procedures and personal
   protective equipment (PPE). On the other hand, formal e-recycling
   industry refers to regular e-recycling facilities sorting materials
   from e-waste with automatic machinery and manual labor, where pollution
   control and PPE are common.^[131]^[152] Sometimes formal e-recycling
   facilities dismantle the e-waste to sort materials, then distribute it
   to other downstream recycling department to further recover materials
   such as plastic and metals.^[152]

   The health impact of e-waste recycling workers working in informal
   industry and formal industry are expect to be different in the
   extent.^[152] Studies in three recycling sites in China suggest that
   the health risks of workers from formal e-recycling facilities in
   Jiangsu and Shanghai were lower compared to those worked in informal
   e-recycling sites in Guiyu.^[132] The primitive methods used by
   unregulated backyard operators (e.g., the informal sector) to reclaim,
   reprocess, and recycle e-waste materials expose the workers to a number
   of toxic substances. Processes such as dismantling components, wet
   chemical processing, and incineration are used and result in direct
   exposure and inhalation of harmful chemicals. Safety equipment such as
   gloves, face masks, and ventilation fans are virtually unknown, and
   workers often have little idea of what they are handling.^[153] In
   another study of e-waste recycling in India, hair samples were
   collected from workers at an e-waste recycling facility and an e-waste
   recycling slum community (informal industry) in Bangalore.^[154] Levels
   of V, Cr, Mn, Mo, Sn, Tl, and Pb were significantly higher in the
   workers at the e-waste recycling facility compared to the e-waste
   workers in the slum community. However, Co, Ag, Cd, and Hg levels were
   significantly higher in the slum community workers compared to the
   facility workers.

   Even in formal e-recycling industry, workers can be exposed to
   excessive pollutants. Studies in the formal e-recycling facilities in
   France and Sweden found workers' overexposure (compared to recommended
   occupational guidelines) to lead, cadmium, mercury and some other
   metals, as well as BFRs, PCBs, dioxin and furans. Workers in formal
   industry are also exposed to more brominated flame-retardants than
   reference groups.^[152]

Hazard controls[edit]

   For occupational health and safety of e-waste recycling workers, both
   employers and workers should take actions. Suggestions for the e-waste
   facility employers and workers given by California Department of Public
   Health are illustrated in the graphic.

   CAPTION: Safety suggestion for e-waste recycling facilities employers
   and workers^[146]

   Hazards What must employers do What should workers do
   General Actions include:
    1. Determine the hazards in the workplace and take actions to control
       them;
    2. Check and make correction to the workplace condition regularly;
    3. Supply safe tools and PPE to workers;
    4. Provide workers with training about hazards and safe work practice;
    5. A written document about injury and illness prevention.

   Suggestions include:
    1. Wear PPE when working;
    2. Talk with employers about ways to improve working conditions;
    3. Report anything unsafe in the workplace to employers;
    4. Share experience of how to work safely with new workers.

   Dust Actions include:
    1. Offer a clean eating area, cleaning area and supplies, uniforms and
       shoes, and lockers for clean clothes to the workers;
    2. Provide tools to dismantle the e-waste.

   If the dust contains lead or cadmium:
    1. Measure the dust, lead and cadmium level in the air;
    2. Provide cleaning facilities such as wet mops and vacuums;
    3. Provide exhaust ventilation. If it is still not sufficient to
       reduce the dust, provide workers with respirators;
    4. Provide workers with blood lead testing when lead level is not less
       than 30 mg/m3.

   Protective measures include:
    1. Clean the workplace regularly, and do not eat or smoke when dealing
       with e-waste;
    2. Don't use brooms to clean the workplace since brooms can raise
       dust;
    3. Before going home, shower, change into clean clothes, and separate
       the dirty work clothes and clean clothes;
    4. Test the blood lead, even if the employers don't provide it;
    5. Use respirator, check for leaks every time before use, always keep
       it on your face in the respirator use area, and clean it properly
       after use.

   Cuts and lacerations Protective equipment such as gloves, masks and eye
   protection equipments should be provided to workers When dealing with
   glass or shredding materials, protect the hands and arms using special
   gloves and oversleeves.
   Noise Actions include:
    1. Measure the noise in the workplace, and use engineering controls
       when levels exceed the exposure limit;
    2. Reduce the vibration of the working desk by rubber matting;
    3. Provide workers with earmuffs when necessary.

   Wear the hearing protection all the time when working. Ask for the
   employer about the noise monitoring results. Test the hearing ability.
   Lifting injuries Provide facilities to lift or move the e-waste and
   adjustable work tables. When handling e-waste, try to decrease the load
   per time. Try to get help from other workers when lifting heavy or big
   things.
