Electronic waste recycling, electronics recycling, or e-waste recycling is the disassembly and separation of components and raw materials of waste electronics; when referring to specific types of electronic waste, the terms like computer recycling or mobile phone recycling may be used. Like other waste streams, reuse, donation, and repair are common sustainability ways to dispose of information technology (IT) waste.
Since its inception in the early 1990s, more and more devices are being recycled worldwide due to increased awareness and investment. Electronic recycling occurs primarily to recover valuable, rare-earth metals and , which are in short supply, as well as plastics and metals. These are resold or used in new devices after purification, in effect creating a circular economy. Such processes involve specialised facilities and premises, but within the home or ordinary workplace, sound components of damaged or obsolete computers can often be reused, reducing replacement costs.
Recycling is considered environmentally friendly because it prevents hazardous waste, including heavy metals and carcinogens, from entering the atmosphere, landfill, or waterways. While electronics make up a small fraction of total waste generated, they are far more dangerous. There is stringent legislation designed to enforce and encourage the sustainable disposal of appliances, the most notable being the Waste Electrical and Electronic Equipment Directive of the European Union and the United States National Computer Recycling Act.National Computer Recycling Act of 2005, H.R. 425, 109th Cong. (2005–2006) In 2009, 38% of and a quarter of total electronic waste were recycled in the United States, 5% and 3% up from 3 years prior, respectively.
In 2007, the United States Environmental Protection Agency (EPA) stated that more than 63 million computers in the U.S. were traded in for replacements or discarded. Today, 15% of electronic devices and equipment are recycled in the United States. Most electronic waste is sent to or Incineration, which releases materials such as lead, mercury, or cadmium into the soil, groundwater, and atmosphere, thus having a negative impact on the environment.
Many materials used in computer hardware can be recovered by recycling for future production. The reuse of tin, silicon, iron, aluminium, and a variety of plastics that are present in bulk in computers or other electronics can reduce the costs of constructing new systems. Components frequently contain copper, gold, tantalum, silver, platinum, palladium, and lead as well as other valuable materials suitable for reclamation.
Computer components contain many toxic substances, like dioxins, polychlorinated biphenyls (PCBs), cadmium, chromium, radionuclide, and mercury. A typical computer monitor may contain more than 6% lead by weight, much of which is in the lead glass of the cathode-ray tube (CRT). A typical 15-inch (38 cm) computer monitor may contain of lead, but other monitors have been estimated to have up to of lead. Circuit boards contain considerable quantities of lead-tin solders that are more likely to leach into groundwater or create air pollution due to incineration. In US landfills, about 40% of the lead content levels are from e-waste. The processing (e.g., incineration and acid treatments) required to reclaim these precious substances may release, generate, or synthesize toxic byproducts.
Export of waste to countries with lower environmental standards is a major concern. The Basel Convention includes such as, but not limited to, CRT screens as an item that may not be exported transcontinentally without the prior consent of both the country exporting and receiving the waste. Companies may find it cost-effective in the short term to sell outdated computers to less developed countries with lax regulations. It is commonly believed that a majority of surplus laptops are routed to developing nations. In The high value of working and reusable laptops, computers, and components (e.g., RAM) can help pay the cost of transportation for many worthless commodities. Laws governing the exportation of waste electronics are put in place to govern recycling companies in developed countries, which ship waste to Third World countries. However, concerns about the impact of e-recycling on human health, the health of recycling workers, and environmental degradation remain. For example, due to the lack of strict regulations in developing countries, sometimes workers smash old products, propelling toxins onto the ground, contaminating the soil, and putting those who do not wear shoes in danger. Other procedures include burning away wire insulation and acid baths to resell circuit boards. These methods pose environmental and health hazards, as toxins are released into the air and acid bath residue can enter the water supply.
Pan-European adoption of the legislation was slow on take-up, with Italy and the United Kingdom being the final member states to pass it into law. The success of the WEEE directive has varied significantly from state to state, with collection rates varying between 13 kilograms per capita per annum to as little as 1 kg per capita per annum. Computers & electronic waste collected from households within Europe are treated under the WEEE directive via Producer Compliance Schemes (whereby manufacturers of electronics pay into a scheme that funds its recovery from household waste recycling centres (HWRCs) and nominated waste treatment facilities (known as Obligated WEEE).
However, recycling of ex-corporate computer hardware and associated electronic equipment falls outside the Producer Compliance Scheme (known as non-obligated). In the UK, waste or obsolete corporate-related computer hardware is treated via third-party authorized treatment facilities, which normally impose a charge for its collection and treatment.
Since mid-2020, the classification of WEEE has changed with regard to POPs (persistent organic pollutants). In the UK, WEEE containing POPs is now classified as a hazardous waste, which includes printed circuit boards, cable from WEEE, and categories 1,2,3,6,7 (cat 4 and 5 unless evidence provided to the contrary).
In 2001, Arkansas enacted the Arkansas Computer and Electronic Solid Waste Management Act, which requires that state agencies manage and sell surplus computer equipment, establishes a computer and electronics recycling fund, and authorizes the Division of Environmental Quality, a subset of the Arkansas Department of Energy and Environment, to regulate and/or ban the disposal of computer and electronic equipment in Arkansas landfills.
In 2003, California passed the Electronic Waste Recycling Act (EWRA), which established California's system for managing e-waste. It mandated electronics manufacturers to submit an annual report detailing efforts to reduce hazardous substances. It required fees, based on screen sizes, to be paid during sales of covered electronic devices and added restrictions on hazardous materials like lead and mercury in electronic devices. The program is scheduled to expand in 2026 to include battery-embedded products. All fees paid are proceeds towards environmentally responsible recycling and disposal of electronic devices in California.
In 2010, the New York State Electronic Equipment Recycling and Reuse Act was signed into law, mandating electronics manufacturers to disclose the levels of regulated materials, like lead, in products to ensure they remain within legal limits. It also required anyone responsible for collecting electronic waste to report details concerning the consumers that provided the waste, as well as the manner in which they disposed of this waste, ensuring compliance with previous regulations. The New York State Department of Environmental Conservation is responsible for overseeing these regulations, collection sites, and ensuring overall compliance with environmental laws.
In Ontario, the Electrical and Electronic Equipment (EEE) Regulation (O. Reg. 522/20) mandates producers to establish systems for the collection and proper disposal of electronic products. Producers of information technology, telecommunications, and audio-visual (ITT/AV) equipment were required to register by November 30, 2020, with collection and management obligations commencing on January 1, 2021.
In Quebec, the " Regulation respecting the recovery and reclamation of products by enterprises" (Q-2, r. 40.1) governs the recycling of electronic waste (e-waste). This regulation requires companies to collect and recycle the electronic products they sell, encouraging the development of ecologically sustainable products.
The Electronic Products Recycling Association of Québec (EPRA-Québec), an industry-led, not-for-profit organization, manages the province's e-waste recycling program. Residents can drop off their unwanted electronics free of charge at EPRA-Québec authorized collection points. The program funds itself through Environmental Handling Fees (EHF) applied to new electronic products sold in Quebec.
Similarly, British Columbia has adopted extended producer responsibility (EPR) programs under its Recycling Regulation, requiring manufacturers to manage the collection and recycling of electronic waste.
It is required in South Korea and Taiwan that sellers and manufacturers of electronics be responsible for recycling 75% of their used products. In South Korea, some local governments have introduced recycling initiatives, such as the case of Seoul, which launched its specialized e-waste recycling program. This includes the SR Center recycling facility, which takes apart and salvages materials from a fifth of the 10-ton e-waste that the city generates each year.
According to a report by UNEP titled, "Recycling – from E-Waste to Resources," the amount of e-waste produced – including mobile phones and computers – could rise by as much as 500 percent over the next decade in some countries, such as India.
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.
Organizations like A2Z Group have stepped in to take up the responsibility to collect and recycle e-waste at various locations in India.
In China, several key regulations have been implemented to manage electronic waste.
In November 2004, the National Development and Reform Commission (NDRC) established the Management of Recycling Home Appliances and Electronic Equipment policy to improve the recovery of valuable materials in discarded electronic devices, like gold, silver, and copper, reducing the need to extract new raw materials from the earth.
In March 2007, the Ministry of Industry and Information Technology (MIIT), National Development and Reform Commission, the Ministry of Commerce, and multiple other government agencies introduced the Management Methods for Pollution Control of IT Products to regulate hazardous substances in electronic products. It mandated manufacturers of electronics to minimize the use of hazardous materials in products and to label their toxic components. It required electronic products imported from other countries to also abide by national standards. These government agencies oversee implementation, imposing penalties such as fines for non-compliance.
In Singapore, the Environmental Public Health Act (EPHA) was amended in April 2014 to introduce the Mandatory Waste Reporting scheme (MWR). This required, upon written notice from the National Environment Agency, to report annual waste data and submit waste reduction plans. Mandatory Food Waste Segregation Who Are We? What Is Mandatory Food Waste Segregation? 2021.[1] The MWR was introduced to focus management attention on waste volumes.Ong, Sharon. Country 3R Progress Report Name of the Country: Singapore Name, Designation and Organization Respondent.[2] Affected premises were to report via the Waste and Resource Management System (WRMS), detailing waste disposal, recycling quantities, and progress on reduction initiatives. They were also required to keep waste disposal records for at least five years. The National Environment Agency provided guidelines, training, and practices for hotels, malls, and industrial developments to support waste management efforts.
The National Environmental Management Act of 1998 established the National Environmental Advisory Forum to advise the Minister of Forestry, Fisheries, and the Environment on matters pertaining to the sustainability of the environment in South Africa. The act aims to integrate environmental management into all development activities, ensuring sustainability while progressing the economy and protecting natural resources.
The National Environmental Management: Waste Act of 2008 was established to regulate waste management in South Africa by setting standards and frameworks for responsible waste disposal and reduction. The act aims to minimize the environmental impact of waste by promoting recycling, recovery, and sustainable waste management practices while supporting economic growth and protecting natural resources.
Under the act, penalties for violations vary based on the severity of the offence. For severe offences, violations such as illegal waste disposal or causing significant environmental harm could result in a fine of up to R10 million, imprisonment for up to 10 years, or both. Less severe offences carry penalties of up to R5 million in fines, imprisonment for up to five years, or both. Minor and continuing offences may result in fines for up to R1,000 per day and imprisonment for a duration ranging from 20 days to six months.
Corporations face risks both for incompletely destroyed data and for improperly disposed of computers. In the UK, some recycling companies use a specialized WEEE-registered contractor to dispose of IT equipment and electrical appliances. In America, under the Resource Conservation and Recovery Act, companies are liable for compliance with regulations even if the recycling process is outsourced. Companies can mitigate these risks by requiring waivers of liability, audit trails, certificates of data destruction, signed confidentiality agreements, and random audits of information security. The National Association of Information Destruction is an international trade association for data destruction providers.
Hewlett-Packard also offers free recycling, but only one of its "national" recycling programs is available nationally, rather than in one or two specific states. Hewlett-Packard also offers to pick up any computer product of any brand for a fee, and to offer a coupon against the purchase of future computers or components; it was the largest computer recycler in America in 2003, and it has recycled over of electronic waste globally since 1995. It encourages the shared approach of collection points for consumers and recyclers to meet.
Many companies purchase and recycle all brands of working and broken and notebook computers from individuals and corporations. Building a market for recycling desktop computers has proven more difficult than exchange programs for laptops, , and other smaller electronics. A basic business model is to provide a seller with an instant online quote based on laptop characteristics, then to send a shipping label and prepaid box to the seller, to erase, reformat, and process the laptop, and to pay rapidly by cheque. A majority of these companies are also generalized electronic waste recyclers as well; organizations that recycle computers exclusively include Cash For Laptops, a laptop refurbisher in Nevada that claims to be the first to buy laptops online in 2001.
In many developing countries, informal recycling practices—such as manual dismantling, open burning, and crude plastic processing—release toxic metals, including arsenic, manganese, nickel, lead, and zinc, along with organic pollutants like flame retardants, PCBs, and dioxins. Workers exposed to these substances face severe health risks, including respiratory problems and cancer.
Improper recycling also leads to soil and water contamination as hazardous metals leach into the environment, degrading water quality and soil health. Techniques like acid leaching and dismantling emit persistent toxins such as PCBs and dioxins that accumulate over time, posing lasting ecological and health threats.
Moreover, many informal methods are inefficient, recovering fewer materials and causing greater environmental damage. Improperly processed e-waste often becomes non-recyclable, compounding the waste problem. Some techniques are also energy-intensive, offsetting the environmental gains of recycling. Without stronger regulations and safer recycling systems, the environmental costs of current practices may surpass their economic benefits, highlighting the urgent need for more sustainable approaches.
In 1991, the first electronic waste recycling system was implemented in Switzerland, beginning with collection of old refrigerators but gradually expanding to cover all devices. The organisation SWICO handles the programme, and is a partnership between IT retailers.
The first publication to report the recycling of computers and electronic waste was published on the front page of the New York Times on April 14, 1993, by columnist Steve Lohr. It detailed the work of Advanced Recovery Inc., a small recycler, in trying to safely dismantle computers, even if most waste was landfilled. Several other companies emerged in the early 1990s, chiefly in Europe, where national 'take back' laws compelled retailers to use them.
After these schemes were set up, many countries could not deal with the sheer quantity of e-waste they generated or its hazardous nature. They began to export the problem to developing countries without enforced environmental legislation. This is cheaper: the cost of recycling computer monitors in the US is ten times more than in China. Demand in Asia for electronic waste began to grow when scrap yards found they could extract valuable substances such as copper, iron, silicon, nickel, and gold during the recycling process.
The Waste Electrical and Electronic Equipment Directive (WEEE Directive) became European Law in February 2003 and covers all aspects of recycling all types of appliances. This was followed by the Electronic Waste Recycling Act, enshrined in California law in January 2005
The 2000s saw a large increase in both the sale of electronic devices and their growth as a waste stream: in 2002, e-waste grew faster than any other type of waste in the EU. This caused investment in modern, automated facilities to cope with the influx of redundant appliances.
Investment in e-cycling facilities has been increasing recently due to technology's rapid rate of obsolescence, concern over improper methods, and opportunities for manufacturers to influence the secondary market (used and reused products). Higher metal prices can result in more recycling taking place. The controversy around methods stems from a lack of agreement over preferred outcomes.
World markets with lower disposable incomes consider 75% repair and reuse to be valuable enough to justify 25% disposal. Debate and certification standards may be leading to better definitions, though civil law contracts, governing the expected process, are still vital to any contracted process, as poorly defined as "e-cycling".
As an example of negative impacts of e-waste, pollution of groundwater has become so serious in areas surrounding China's landfills that water must be shipped in from away. However, mining of new metals can have even broader impacts on groundwater. Either thorough e-cycling processing, domestic processing or overseas repair, can help the environment by avoiding pollution. Such e-cycling can theoretically be a sustainable alternative to disposing of e-waste in landfills. In addition, e-cycling allows for the reclamation of potential conflict minerals, like gold and wolframite, which requires less of those to be mined and lessens the potential money flow to militias and other exploitative actors in third-world that profit from mining them.
Supporters of one form of "required e-cycling" legislation argue that e-cycling saves taxpayers money, as the financial responsibility would be shifted from the taxpayer to the manufacturers. Advocates of more simple legislation (such as landfill bans for e-waste) argue that involving manufacturers does not reduce the cost to consumers, if reuse value is lost, and the resulting costs are then passed on to consumers in new products, particularly affecting markets which can hardly afford new products. It is theorized that manufacturers who take part in e-cycling would be motivated to use fewer materials in the production process, create longer lasting products, and implement safer, more efficient recycling systems. This theory is sharply disputed and has never been demonstrated.
Another opposition to e-cycling is that many problems are posed in disassembly: the process is costly and dangerous because of the heavy metals of which the electronic products are composed, and as little as 1–5% of the original cost of materials can be retrieved. A final problem that people find is that identity fraud is all too common in regards to the disposal of electronic products. As the programs are legislated, creating winners and losers among e-cyclers with different locations and processes, it may be difficult to distinguish between criticism of e-cycling as a practice, and criticism of the specific legislated means proposed to enhance it.
Although not possible in all circumstances, the best way to e-cycle is to upcycle e-waste. On the other hand, the electronic products in question are generally manufactured, and repaired under warranty, in the same nations, which anti-reuse recyclers depict as primitive. Reuse-based e-recyclers believe that fair-trade incentives for export markets will lead to better results than domestic shredding. There has been a continued debate between export-friendly e-cycling and increased regulation of that practice.
In the European Union, debate regarding the export of e-waste has resulted in a significant amendment to the WEEE directive (January 2012) with a view to significantly diminishing the export of WEEE (untreated e-waste). During debate in Strasburg, MEPs stated that "53 million tonnes of WEEE were generated in 2009 but only 18% collected for recycling" with the remainder being exported or sent to landfill. The Amendment, voted through by a unanimous 95% of representatives, removed the re-use (repair and refurbishmet) aspect of the directive and placed more emphasis upon recycling and recovery of precious metals and base metals. The changes went further by placing the burden upon registered exporters to prove that used equipment leaving Europe was "fit for purpose".
As of September, 2006, Dell developed the nation's first completely free recycling program,Moore, Elizabeth Armstrong. "Momentum Builds for 'Revolution' to Recycle Electronic Waste." 31 July 2006. The Christian Science Monitor. Accessed 29 November 2007. [6] . furthering the responsibilities that manufacturers are taking for e-cycling. Manufacturers and retailers such as Best Buy, Sony, and Samsung have also set up recycling programs. This program does not accept televisions, which are the most expensive used electronic item, and are unpopular in markets which must deal with televisions when the more valuable computers have been cherry picked.
Another step being taken is the recyclers' pledge of true stewardship, sponsored by the Computer Takeback Campaign. It has been signed by numerous recyclers promising to recycle responsibly. Grassroots efforts have also played a big part in this issue, as they and other community organizations are being formed to help responsibly recycle e-waste. Other grassroots campaigns are Basel, the Computer TakeBack Campaign (co-coordinated by the Grassroots Recycling Network), and the Silicon Valley Toxics Coalition. No study has shown any difference in recycling methods under the Pledge, and no data is available to demonstrate difference in management between "Pledge" and non-Pledge companies, though it is assumed that the risk of making false claims will prevent Pledge companies from wrongly describing their processes.
Many people believe that the U.S. should follow the European Union model in regards to its management of e-waste, such as the Extended Producer Responsibility, which was started in Sweden in 1990. In this program, a directive forces manufacturers to take responsibility for e-cycling; it also demands manufacturers' mandatory take-back and places bans on exporting e-waste to developing countries. British Columbia has more than 20 EPR programs under the Recycling Regulation legislation, which stops e-waste from being put into landfills and recycles them instead. There are more than 80 programs in Canada as of 2013.
Another longer-term solution is for computers to be composed of less dangerous products and many people disagree. No data has been provided to show that people who agree with the European model have based their agreement on measured outcomes or experience-based scientific method.
Government contracts have been discovered on hard drives found in Agbogbloshie, Ghana. Multimillion-dollar agreements from United States security institutions such as the Defense Intelligence Agency (DIA), the Transportation Security Administration and Homeland Security have all resurfaced in Agbogbloshie.Doctorow, Cory. "Illegal E-waste Dumped in Ghana Includes Unencrypted Hard Drives Full of US Security Secrets." Boing Boing. 25 June 2009. Web. 15 March 2011.
There is also a major backlash from the consumer if there is a data breach in a company that is supposed to be trusted to protect their private information. If an organization has any consumer info on file, they must by law (Red Flags Clarification act of 2010) have written information protection policies and procedures in place, that serve to combat, mitigate, and detect vulnerable areas that could result in identity theft. The United States Department of Defense has published a standard to which recyclers and individuals may meet in order to satisfy HIPAA requirements.
The typical process for computer recycling aims to securely destroy hard drives while still recycling the byproduct. A typical process for effective computer recycling:
The Asset Disposal and Information Security Alliance (ADISA) publishes an ADISA IT Asset Disposal Security Standard that covers all phases of the e-waste disposal process from collection to transportation, storage and sanitization's at the disposal facility. It also conducts periodic audits of disposal vendors.
