Scrapped mobile phones.

Mobile phone recycling describes the waste management of mobile phones, to retrieve materials used in their manufacture. Rapid technology change, low initial cost, and planned obsolescence have resulted in a fast-growing surplus, which contributes to the increasing amount of electronic waste around the globe.

Recycling

Most cell phones contain precious metals [1] and plastics that can be recycled to save energy and resources that would otherwise be required to mine or manufacture. When placed in a landfill, these materials can pollute the air and contaminate soil and drinking water. [2]

Humans toss millions of cell phones each year in favor of newer technology—and all those discarded phones may be taking a toll on the environment. [3] Electronic scrap accounts for 70% of the overall toxic waste currently found in landfills in the U.S.A. According to the U.S. Environmental Protection Agency (EPA), 420 million mobile phones were discarded in 2009 and only 12 million of those were collected for recycling. [4]

A cell phone's shelf life is only about 24 months for the average user. [5] This means that newer cell phone models are constantly put up on the market to replace older ones. This is as a result of the rapid progression of technology in the mobile industry. According to Matt Ployhar of Intel, the industry is rapidly evolving, possibly even at “Moore's law pace or faster.” [6] This means that newer cell phone models are continually on the rise of consumerism and more outdated models are likely to end up in landfills.

Process

Chemical composition

Mobile phones have a rich and complex composition for recycling. [7] In one ton of cellphones, there are 3,573 grams of silver, 368 grams of gold, and 287 grams of palladium. [8] Mobile phones typically contain the following components: printed circuit board (PCB), liquid crystal display (LCD), camera, flexible substrate and motor, and speaker and microphone. [7] These components are made from hazardous, precious, and base elements. [7] The PCB is made of lead, arsenic, gold, silver, copper, aluminum, and other base metals. [7] The LCD is made of gold, silver, arsenic, barium, copper, and other base metals. [7] The camera is made of silver, copper, and nickel. [7] The flexible substrate and motor is made of silver, gold, copper, and platinum. [7] The speaker and microphone are made of copper, manganese, and zinc. [7]

Collection

Methods for collecting used mobile phones include the following incentives: pre-paid shipping labels and envelopes, take-back programs, and drop-off points. [9] Some companies and manufacturers offer pre-paid shipping labels online so that consumers can ship their used devices free of charge. [9] Take-back programs give consumers monetary incentives in the forms of account credits, discounts, and lump-sum cash payments to promote the recycling of mobile phones. [9] For instance, the Apple Trade In program gives consumers a credit towards their next purchase or an Apple Gift Card when they trade in an eligible device. [10] Manufacturers also maintain drop-off boxes or points located in stores and facilities. [9] Drop-off points are usually found in highly visible and high-traffic areas that pose convince to potential recyclers. [9]

Global impact

Electronic waste (e-waste) is a global problem; especially since many developed countries, including the U.S., ship their discarded electronic devices to less developed parts of the world. Oftentimes, the e-waste is improperly dismantled and burned, producing toxic emissions harmful to waste site workers, children, and nearby communities. Therefore, it is important for cell phone users to dispose of and recycle their devices responsibly and ethically.

Mobile phones currently pose a huge problem for numerous countries around the world. Manufacturers and agencies are slowly adapting new programs in an effort to curtail the amount of waste that has been rising over the years.

Australia

A national mobile recycling program was accredited in 2014. [11] This program, MobileMuster, originated in 1998 after a successful recycling trial in one of their states. Currently, its main focus is centered around mobile phones, batteries and any related accessories. They collaborate with over 1,400 retailers, local councils, government agencies and businesses in their recycling efforts. In 2005 MobileMuster launched a campaign that gathered statistical data showing 46% of the Australian population was aware of the option to recycle their mobile devices and its accessories. The greatest benefit that arose from this research was the simple fact that raising public awareness of a recycling program actually lead to a large spike in the number of devices being recycled. In March 2006, awareness had increased to 54%. By the end of June more than 590,000 devices and 1.5 million batteries had been collected by MobileMuster. This amounts to roughly 367 tons of material, which is the equivalent to a 16% increase in the number of devices over the span of a year. Today, they are placing a heavy emphasis on not only recycling phones but rather reusing them. The reasoning behind this is that reusing leads to a decreased amount of resources being extracted from the environment, therefore minimizing the impact. [12]

North America

Because the U.S. has not ratified the Basel Convention or its Ban Amendment, and has no domestic laws forbidding the export of toxic waste, the Basel Action Network estimates that about 69% 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. [13] [14] [15] [16]

It was originally predicted that volumes for the US mobile phone recycling industry would see a notable increase until at least 2019, due to an upturn in mobile phone ownership and therefore a larger base of phones would be available for recycling. [17] However the amount of ownership has exceeded most historic industry expectations - approximately 150 million mobile phones are discarded each year in the USA. [4] Approximately 17 tonnes of copper and 0.3 tonnes of silver can be recovered per 1 million devices recycled. A 'marginal' amount of gold and palladium can also be extracted. [17]

A report released in early 2014 found that when it comes to mobile phone recycling programs, cash is the single biggest incentive for consumers in recycling phones. [18] As more people became aware of the monetary value of their old cell phones and other small electronics such as tablets, comparison websites showing users the latest buying prices grew in popularity. There are now dozens of electronics buyback companies that will purchase electronics from consumers and organizations. Trusted buyback companies are focused on paying out cash for unused, old, or broken electronics. These companies are helping drive growth in the circular economy of used devices.

The first mobile phone recycling company in the U.S. was ReCellular, which was founded in 1991 when there were only 16 million mobile subscribers worldwide; it went bankrupt in 2013. [19]

California passed the Cell Phone Recycling Act of 2004, which requires cell phone retailers to collect the cell phones for reuse, recycling, or disposal, making it easier for consumers to recycle their old cell phones. [20] As of July 1, 2006, it is unlawful for a retailer to sell a cell phone to a consumer in California unless the retailer complies with this law. [20] California's Department of Toxic Substances Control reported that in 2020, 8.47 million phones were sold in California and 1.34 million phones were returned for recycling, which amounts to a 15.9% recycling rate. This rate was an increase from 2019, when the recycling rate was 8.6%. [21]

United Kingdom

Both the United Kingdom and mainland Europe have a significant problem with e-waste. Researchers at Plymouth University found that for each mobile phone produced, 15 kg of ore needs to be mined, including 7 kg of high-grade gold ore, 1 kg of typical copper ore, 750g of typical tungsten ore and 200g of typical nickel ore. In the UK, only around 12% of all mobile phones that have been sold have gone on to be recycled. [22] [23]

According to a study from Compare and Recycle, people in the UK upgraded their mobile phones at least 3 times in the past 10 years, and 22% of people chose to trade in or resell their used mobile phones. However, 40% kept old mobile phones stashing them in their homes. [24]

Value of recycling

Mobile phones have value well after their intended use. Yet the value of these phones to recyclers is marginal and relies on high volume to become profitable. The economic value of recycled cell phones is split into two categories; refurbished units that are resold to end users and phones that have no value to retail consumers that are recycled for their precious metals.

The University of California Santa Barbara published a study in 2010 on the subject called, "Economics of Cell Phone Reuse and Recycling" that states the value of reused and recycled cell phones. In 2006, according to the study the average cost for U.S. cell phone refurbishers ReCellular, PaceButler and RMS was $2.10 while the average revenue from said phones was $17. [25] Of the two recycling methods, refurbishment of cell phones is significantly more profitable than recycling the internal parts.

The study also describes the value of all precious metals inside of cell phones as well as the cost of extracting said metals. The average cost in 2006 to extract the precious metals for the U.S. cell phone recycling company ECS Refining was $.18 while the average revenue from the recycled metals was $.75. [26] With a profit margin significantly smaller than refurbished units, this method of gaining economic value from the recycling of cell phones is significantly more volume dependent. The most valuable precious metal in cell phones is Gold which is used in the unit's microprocessor. This precious metals percentage of the total mass of phones has constantly decreased over time. From 1992 to 2006, gold as a percentage of total mass of cell phones dropped from .06% to .03%. [27] There is a significant amount of volume in the U.S. market with Americans in 2009 throwing away on average 350,000 cell phones a day but with thinning margins, volume starts to become irrelevant. [28]

Therefore, the economic incentive for recycling the precious metals in cell phones is decreasing in the United States as manufacturers look for more cost effective ways to produce cell phones. Refurbishing and reselling cell phones continues to be the most economically viable option for recycling this form of e-waste. Furthermore, among consumers, refurbished cell phones are becoming more popular as a cheaper alternative to new smartphones. Environmentally, a refurbished smartphone has a significantly smaller carbon footprint while also eliminating the need for extracting raw materials, saving 261.3 kg of raw materials per mobile phone.

Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution and water pollution.

Consumer electronics or home electronics are electronic equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment, communications and recreation. These products are usually referred to as black goods in American English, due to many products being housed in black or dark casings. This term is used to distinguish them from "white goods" which are meant for housekeeping tasks, such as washing machines and refrigerators. In British English, they are often called brown goods by producers and sellers. In the 2010s, this distinction is absent in large big box consumer electronics stores, which sell entertainment, communication and home office devices, light fixtures and appliances, including the bathroom type.

Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap can have monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types – typically metal scrap will be crushed, shredded, and sorted using mechanical processes.

<span class="mw-page-title-main">Electronic waste recycling</span> Form of recycling

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 e-waste, the terms like computer recycling or mobile phone recycling may be used.

<span class="mw-page-title-main">Electronic waste</span> Discarded electronic devices

Electronic waste describes discarded electrical or electronic devices. It is also commonly known as waste electrical and electronic equipment (WEEE) or end-of-life (EOL) electronics. 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. The growing consumption of electronic goods due to the Digital Revolution and innovations in science and technology, such as bitcoin, has led to a global e-waste problem and hazard. The rapid exponential increase of e-waste is due to frequent new model releases and unnecessary purchases of electrical and electronic equipment (EEE), short innovation cycles and low recycling rates, and a drop in the average life span of computers.

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

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

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

Guiyu, in Guangdong Province, China, is widely perceived as the largest electronic waste (e-waste) site in the world. In 2005, there were 60,000 e-waste workers in Guiyu who processed the more than 100 truckloads that were transported to the 52-square-kilometre area every day. The constant movement into and processing of e-wastes in the area leading to the harmful and toxic environment and living conditions, coupled with inadequate facilities, have led to the Guiyu town being nicknamed the "electronic graveyard of the world".

<span class="mw-page-title-main">Electronic waste in the United States</span>

Electronic waste or e-waste in the United States refers to electronic products that have reached the end of their operable lives, and the United States is beginning to address its waste problems with regulations at a state and federal level. Used electronics are the quickest-growing source of waste and can have serious health impacts. The United States is the world leader in producing the most e-waste, followed closely by China; both countries domestically recycle and export e-waste. Only recently has the United States begun to make an effort to start regulating where e-waste goes and how it is disposed of. There is also an economic factor that has an effect on where and how e-waste is disposed of. Electronics are the primary users of precious and special metals, retrieving those metals from electronics can be viewed as important as raw metals may become more scarce

As a nation, Americans generate more waste than any other nation in the world, officially with 4.4 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, with another study estimating 7.1 pounds (3.2 kg) per capita per day. Fifty five percent of this waste is contributed as residential garbage, while the remaining forty five percent of waste in the U.S.'s 'waste stream' comes from manufacturing, retailing, and commercial trade in the U.S. economy. According to the American Society of Civil Engineers, Nevada produces the most waste at "[nearly] 8 pounds (3.6 kg) per person per day". Approximately 90% of all waste produced by Nevadans ends up in landfills. "Wasteful" states Michigan, New Mexico, Wisconsin and Oregon as well as Washington also dominated the list's 5-year period.

<span class="mw-page-title-main">Appliance recycling</span> Process of dismantling scrapped home appliance for reuse

Appliance recycling is the process of dismantling scrapped home appliances to recover their parts or materials for reuse. Recycling appliances for their original or other purposes, involves disassembly, removal of hazardous components and destruction of the equipment to recover materials, generally by shredding, sorting and grading. The rate at which appliances are discarded has increased due in part to obsolescence due to technological advancement, and in part to not being designed to be repairable. The main types of appliances that are recycled are televisions, refrigerators, air conditioners, washing machines, and computers. When appliances are recycled, they can be looked upon as a valuable resources; if disposed of improperly, they can be environmentally harmful and poison ecosystems.

Closing the Loop is a company that offers a closed loop service for mobile phones. The Dutch social enterprise is based in Amsterdam, the Netherlands. It was founded with the aim to reduce electronic waste (e-waste). It does this by offering users and sellers of phones a way to make their device material-neutral and waste free. The company pays people in emerging markets to collect scrap phones. These phones are then recycled for Closing the Loop’s customers. The proposition works on a one for one basis, where a customer’s phone is ‘offset’ by the recycling of a broken phone. Known customers are Shiftphone, T-Mobile, KPMG, the city of Utrecht, Rabobank and the Dutch national government.

Electrical and electronic equipment (EEE) waste, or e-waste, is illegally brought into African states every year. A minimum of 250,000 metric tons of e-waste comes into the continent, and according to the Swiss Federal Laboratories for Materials Science and Technology, the majority of it in West Africa enters from Europe. Developed countries commodify underdeveloped African states as dumping grounds for their e-waste, and due to poor regulations and a lack of enforcement institutions, illegal dumping is promoted. Currently, the largest e-waste dumping site in Africa is Agbogbloshie in Ghana. While states like Nigeria do not contain e-waste sites as concentrated as Agbogbloshie, they do have several small sites.

The environmental impact of Big Tech is a phenomenon in which many aspects of Big Tech contribute to negative impacts on the environment and climate change. In the big data age, technologists and people in general find it valuable to view emerging technologies with a critical lens, one of which is geared toward the environment. As these emerging technologies become more popular, they consider the extent at which they contribute to changes in the environment and whether they are inherently positive or negative.
