Recycling

Most cell phones contain precious metals 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. 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. Electronic scrap accounts for 70% of the overall toxic waste currently found in landfills in the U.S.A. According to the

(EPA), 420 million mobile phones were discarded in 2009 and only 12 million of those were collected for recycling. A cell phone's shelf life is only about 24 months for the average user. 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

pace or faster.” This means that newer cell phone models are continually on the rise of consumerism and more outdated models are likely to end up in landfills.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. In one ton of cellphones, there are 3,573 grams of silver, 368 grams of gold, and 287 grams of palladium. Mobile phones typically contain the following components: printed circuit board (PCB), liquid crystal display (LCD), camera, flexible substrate and motor, and speaker and microphone. These components are made from hazardous, precious, and base elements. The PCB is made of lead, arsenic, gold, silver, copper, aluminum, and other base metals. The LCD is made of gold, silver, arsenic, barium, copper, and other base metals. The camera is made of silver, copper, and nickel. The flexible substrate and motor is made of silver, gold, copper, and platinum. The speaker and microphone are made of copper, manganese, and zinc.

Collection

Methods for collecting used mobile phones include the following the following incentives: pre-paid shipping labels and envelopes, take-back programs, and drop-off points. Some companies and manufacturers offer pre-paid shipping labels online so that consumers can ship their used devices free of charge. 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. 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. Manufacturers also maintain drop-off boxes or points located in stores and facilities. Drop-off points are usually found in highly visible and high-traffic areas that pose convince to potential recyclers.

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. 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.

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. 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.

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. 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. California's

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.

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. 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.
