1 David Haase December 6, 2013 ENVS 428 – Final Paper E-Waste: Impacts and Solutions Solid waste reduction has long been a topic in this country, as well as globally. With the creation of the EPA, and a better understanding of the impacts that a heavy waste stream can have on the environment, the industrialized world has made progress in the treatment and disposal of solid waste. However, those same countries, and America in particular, still live as a throw-away society to a great extent. The convenience of putting our trash at the curb and having it hauled away without having to live with the consequences has made the problem of waste management and accumulation worse as our population has grown. One particularly troubling portion of this increased solid waste is the growth of electronic waste; or e-waste as it is identified today. This is a complicated issue as it deals not only with environmental impacts in countries that have access to a multitude of electronics, but to developing countries as well, since they are often required to bear the burden of the final impacts of this type of pollution. Known as the “digital divide”, people living in poorer countries will rarely have the opportunity to own advanced technologies available today. The environmental injustice becomes much more compelling when those who have no access to these devices must sacrifice their health and ecosystems, so that richer nations can continue to replace and dispose of the devices at an 2 alarming rate. This paper will examine the evolution of e-waste, its current environmental ramifications, and possible solutions to the problem. The Tech Revolution The 1980’s saw an explosion of advancements in electronic devices. Personal computers were becoming as common in homes as televisions, and the silicon chip allowed millions more computations than previously thought possible. Devices such as VCR’s, Walkmans, and the creation of the compact disc, provided people with the convenience of turning on a device and receiving immediate access to entertainment. The cellular phone, a contraption as big as a small toaster, came into being. People who could afford them no longer had to find a payphone or go inside to contact someone. The phone would send a signal that would bounce off a few towers and either connect to a land line, or with another cellular user. These advancements made life easier, and ultimately shrunk the world to allow for globalization and better communication. Ultimately the development of the World Wide Web accelerated the utility of the computer; a device that was believed should only be seen in the hands of academics, or nerds. As time progressed, so did the computing power of these devices. More and more circuitry could be placed on a single chip, not only increasing microprocessor power, but shrinking its size as well. This led to more advanced electronic devices that were smaller, more portable, and even more affordable. Platinum, palladium, silver, copper, and other elements were used in devices to optimize processing power and minimization in size. Devices such as televisions, printers, copiers, and fax machines all contained tiny chips to make them work better and easier. By the late 1990’s, someone 3 without a cell phone, a laptop, a PDA, and a personal computer might as well be living in the stone ages. Knowing how to use a fax machine, a copier, and a printer (usually all the same device) was essential to working in an office setting and made a person more employable. This was true also for software that could be used to write, do spread sheets, and even produce slide-shows. Computer literacy became as important as reading, writing, and arithmetic. These incredible advancements brought America and other developed countries into the Information Age. At the same time however, an increasing number of new and improved gadgetry meant an increase in disposal of the old. While pollution prevention concepts such as recycling and reduction were just starting to take root, people were bombarded with new technologies that companies argued they could not do without. The rate at which consumers switched out the old for the new began to increase exponentially (Luther). Those devices and components which were not necessarily broken or inoperable began to be replaced as quickly as the technology advanced. Also, the average lifetime of such devices began to decline. This combination of increasing obsolescence and decreasing life led to an overall increase in the amount of e-waste being generated, and initiated the crisis we have today. Impacts All waste must be handled and dealt with to some degree. Whether this is at the local level using sanitary landfills, or the international level where waste too expensive to be processed in an industrialized country is exported to other countries where it is cheaper and less regulated. While waste such as aluminum and paper is converted back into a raw material to be used in the manufacturing process with some ease and low environmental impact, 4 complex devices such as computers and cell phones become much more problematic. From the plastics used in the casings, to the heavy metals in the circuit boards and other components, electronic waste is a complicated waste unit comprised of thousands of parts of differing materials. As such, e-waste becomes much more of an expensive and labor intensive item to disassemble and get back into the production stream. The recycling process is very costly and labor intensive. Laws in the United States and other developed countries place heavy restrictions on the practice of tearing apart electronic devices and separating their individual components. Most of the plastics in advanced electronics have fire-retardant materials in them (called BFR’s) which are toxic and hard to separate in a recycling process. Heavy metals, including gold and platinum which are very valuable, are also very costly to handle and remove in an environmentally sound manner. Finally, components that can be retrieved as a whole and are usable do not have a very strong market due to the steady pace at which technology advances. This begins to shape the picture in which the current after-life world of electronics exists. As I mentioned earlier, the throw-away mentality of Americans drives the overall fate of many devices. In addition the relatively low cost to replace these devices as compared to the per capita income of the average American has contributed to the proliferation of electronic waste and its detrimental impacts. Many times mobile devices such as cellular phones or tablets are offered at a greatly discounted rate in exchange for a service contract. Sometimes the initial or replacement phones are offered to the consumer free to incentivize continuing business with a service provider. Let’s use the example of a consumer who has a computer that they’ve owned for about 3 years. The computer has stopped functioning, and the consumer needs a computer to be 5 able to perform their job and stay in touch with family members. The consumer takes the computer back to where they originally bought it. The manufacturer’s warranty has expired and the consumer did not purchase any other protection on the computer. The technician examines the computer and discovers that the cooling fan had stopped working causing the internal components to overheat and some circuits were destroyed. I am by no means any kind of expert on computers, so just to make the argument simple we’ll say the estimated repairs will be about $400.00 plus another $200.00 in labor. While at the store waiting for the technician to look at his computer, the consumer notices a brand new computer which is twice as fast as his old one, has four times the memory, and a better monitor, for only $599.00. Given this information, it would be ridiculous for him to spend the same amount for repairs as it would be for a computer which is much more sophisticated and powerful. Besides the data stored on his old computer, the value of it is essentially $0.00, making the decision to buy the bigger, better product too easy. In this example, the old computer might stay with the store and the consumer might get a credit for the device. The store might even have a process whereby they refurbish the old computer and sell it to an organization that needs cheap computers. The most likely scenario is that any working components will be stripped and the remainder will go to a landfill. Meanwhile, the consumer goes home happy, thinking he has received a great deal and no longer has to worry about the old item. There is no responsibility on the part of the consumer to ensure the electronic device is disposed of ethically and responsibly. 6 According to the EPA, in 2009 computers constituted the most recycled electronic waste out of any devices tracked. This amount however was only 38%, compared to cell phones at 8%, and televisions at 17% (citation). Keep in mind these numbers are based on quantity recycled by weight. Computers with their primarily steel casings and heavy internal components make up a much more significant portion of the waste stream. Overall, only 25% of electronic devices were collected for recycling in 2009, with the remainder heading to sanitary landfills for disposal (EPA (Unknown)). Recycling of electronic devices is a much more complicated situation. Typically if anyone uses the term “recycling”, they appear to be one of the good guys; someone who is trying to make a difference and improve our current environmental situation. However, as you increase the complexity of the recycling, you also increase the cost. Any increase in cost in a capitalistic society requires that that cost be passed off onto someone else, or the process is inefficient and must be eliminated. E-waste recycling as it exists in the U.S. today is extremely time-consuming, labor-intensive, and at a high cost in capital. In order for there to be a profit in the recycling of electronic devices, the labor must be low-paid, regulations must be lowered, or shortcuts need to be made in order to increase profit. In addition there needs to be a solid market for the recovered materials. The recycling of electronics in the U.S. is a very immature endeavor. The most recent data shows just over 500 locations in the U.S. that actively recycle electronic waste in ways c (Puckett, Westervelt and al)ompatible with current environmental regulations. While the number of sites has increased in New England, the Mid-West, and the Pacific Coast, other areas of the country have seen a decline in the number of sites (Hai-Yong). There is still a substantial amount of materials that become exports. Each recycler ends up with 7 either material or components that they can’t, or won’t process. Recyclers can claim to be environmentally friendly because they keep the items out of American landfills, but in fact they are just moving the problem elsewhere. These recyclers contract with downstream vendors who take these materials and ship them to developing countries. In attempting to keep electronic waste out of landfills, many industrialized nations have instituted restrictions and guidelines that incentivize moving the waste out of sight and out of mind. What has evolved over the past 10 years or so is the migration of the business of recycling devices disposed of in America to developing countries worldwide. In 1989 the United Nations met in Basel, Switzerland to discuss the problem of hazardous wastes being shipped to developing nations to be disposed. The convention resulted in guidelines and rules overseeing the movement of hazardous wastes from nation to nation with the intention of preventing disposal in an environmentally unsound manner, and burdening poor nations with the problems of rich nations. The Basel Convention has been amended and updated, and now includes guidelines regarding electronic wastes. However, circumventing this rule is fairly easy, especially for the United States which has yet to ratify the Convention. When a recycler collects items such as computers, TV’s, and cell phones, their primary goal is to process these items at the lowest possible cost. The items are loaded onto a ship container and sent overseas, many times to port cities on the Western coast of Africa, or poor nations in Asia. These items are listed on the bill of lading as items for repair or recycling, and therefore are not regulated under the Basel Convention (Robinson). When the shipment arrives there are no questions at the port, as the bill shows electronic devices for servicing. The broker in the receiving nation picks up the container and takes the items to his village or 8 compound and begins unloading them. What many of these brokers find however, is that less than 25% of the items are even capable of being repaired (Puckett). The majority of the electronic devices are so damaged or outdated that the broker has no choice but to throw them away. As a result these devices get piled up in the open, are burned, or even tossed into local water supplies. The broker will take the items that are somewhat useful and fixes them or breaks them down and sells working components. Instead of the devices getting processed in a country that has environmental protection laws and is more selective in what is disposed, the items are left to deteriorate and contaminate underdeveloped nations who do not have the infrastructure or laws to ensure proper processing. One of the most frustrating parts of this problem is that countries that take in the thousands of containers of devices are actually asking for them(Schmidt). People in poor countries have a strong desire to have modern electronic devices just like those in richer countries. This demand creates the market for recyclers who can increase their profits by simply shipping the problem away, and brokers in the poor countries pay very little if anything for these discarded items. Many of the citizens in the receiving countries make a fairly good living and have become very adept at repairing a wide range of electronics. For them, having one fourth of the shipments capable of making them money is quite alluring, and they know that there will be no penalties for them simply dumping or burning the unusable items. As the United States has not ratified the Basel Convention, there is no reason for American recyclers to stop doing what they are doing. They are turning a profit and they have a “green” image by keeping electronic waste out of American landfills. This makes the problem much more complicated and harder to address. 9 Many countries that do receive electronic items actually do contract to recycle and process the used equipment legally. On the surface it may simply look like another case of outsourcing; using cheaper labor overseas to maximize profits. What is less known is that these operations are dealing with a much more dangerous situation than assembling plastic toys or sewing clothes. As I mentioned earlier, the process to remove valuable materials from electronic devices and turn them into marketable commodities in an ethical way is extremely expensive and complex. The infrastructure is so lacking in these developing countries that the workers are exposed to extreme risk and hazards. Removing plastics from copper wires and extracting valuable metals often requires the use of caustic chemicals. Conditions in these processing locations are terrible, and many times young children are exposed to the same dangerous conditions and chemicals as the adults. Protective clothing and equipment is rarely used and exposure to toxic fumes for 12 hours a day or more is not uncommon. In 2007, a team of scientists visited a town called Guiyu, in the Guangdong province of China to investigate some of the effects of electronic recycling and processing that was occurring there. According to the study, the city of 150,000 is home to the largest e-waste recycling operation in the world. Processing of electronics includes acid digestion of materials, open burning and melting of solder and other metals, and the workers wear no protective goggles or gloves. Most times, spent acids and other wastes are openly dumped on the ground and into local waterways (Coby, et al). The investigators tested sediment and water from two rivers that run through the town near the processing areas. Elevated amounts of lead, cadmium, copper, nickel, and zinc were found in the sediment, and previous studies have shown elevated amounts of PCB’s and PBDE’s in wildlife near the area. The heavy metals and contaminants 10 contained in electronic waste are literally being poured into the ecosystem, affecting not only the environment, but the health of the residents in Guiyu and elsewhere in the region. This site is only one of thousands throughout the developing world, and as the number of used and discarded electronic devices continues to grow, the problem will only get worse. The final option for unwanted e-waste is, unfortunately, disposal. Currently e-waste comprises 2 to 5% of the overall solid waste stream in America, and 8% worldwide (citation). Although this does not seem significant, when one looks at the overall percentages of electronic devices that are disposed rather than recycled, it is quite an alarming amount of potentially dangerous waste. Earlier I had mentioned that only 8% of mobile devices were recovered for recycling in 2009, according to the EPA. This means that close to 135 million phones, tablets, and similar devices made their way into landfills in just one year. Sanitary landfills in the U.S. are quite sophisticated and well designed to keep contaminants out of local environments, but they are not perfect. Considering the amount of heavy metals and chemicals within the plastics of the devices that are soluble, it is only a matter of time before these contaminants leach out and make their way into the soil and water. The primary source of this problem is education and culture. For years, Americans have looked to the trash can as the solution for their waste. The ease at which refuse from American homes is transported away from living areas to processing facilities reduces the notion of responsibility and awareness. However, states are starting to recognize the problem and place restrictions on electronic devices being sent to landfills. Maine, Minnesota, and California have all placed restrictions on disposal of CRT’s in landfills due to the high lead content. Also, California has passed a more comprehensive act to curb the disposal of electronic waste in those states. 11 Although the EPA recognizes the growing importance and complications of electronics in the solid waste stream, they still do not recognize e-waste as a hazardous waste and it does not fall under their schedule regarding handling. They do, however, allow for and promote states to use their own legislation to regulate wastes in their respective landfills as they see fit. Solutions As we have seen, the increasing problem of electronic waste is not as simple as other waste stream issues. The complexity of the devices and their components, the slow growth of an infrastructure to ethically process them, and the ease of which the problem can be pushed away, are all significant road blocks to solutions. There continue to be increases in awareness and advocacy on the topic, but it is very slow as with any type of improvement that involves culture shift. The first step in curbing the amount of any waste product is to reduce. In terms of electronics, this means not purchasing the device in the first place. As members of a modern technological society, it is almost taboo to not have at least a computer and mobile device. PC’s and cellular phones have made it possible for people to stay connected, informed, and organized for a fairly small monetary investment. Having and using these devices is not really the problem. It’s what happens when these devices reach the end of their lives. Although it is tempting to get the new iPhone when it is released, consumers need to stop and think whether it is really necessary. Most cellular service providers design their contracts around a revolving two year set up. At the end of the contract period, providers incentivize renewing by offering a new device at a discount, or even sometimes for free. Although it is unusual to have a device 12 that is in perfect condition at the end of the contract period, most devices are not completely unusable. There may be a new device available with improved features, memory, or a better camera, but what is the environmental cost when you dispose of a working phone to get a new working phone? Obviously, if you have reached the end of the contract period and the phone is no longer functioning it makes sense to replace it. But replacing a computer, TV, printer, or other device in that same amount of time could be considered wasteful. Each one of the new products represents raw materials that have been extracted to produce it, and thousands of tons of carbon released in making the device. Reducing in this context does not mean doing without, it simply means being conscious of the decision to replace an electronic device and ensuring that the old device is either refurbished or recycled ethically. Refurbishment would seem the most logical next step as an electronic device nears the end of its usefulness. Unfortunately, most people choose to go straight to the recycling stage because they are unaware of the limitations of recycling processes in this country. Refurbishing involves taking a device that has reached the end of its useful life, and replacing any nonfunctional components (e.g. broken screen, failed circuit board, etc.). The refurbished product can now be re-sold at a discount to a consumer and used just like it was originally designed, giving the item an extended lifetime. As can be imagined, these efforts can only go so far. Sometimes devices are so damaged, or have reached a point of having too much obsolete technology, that there is no cost effective way of putting it back on the market. The free market thereby concludes how much can be done for a device to keep it from the final stages of the P2 pyramid; treatment and disposal. Obviously, as technology has advanced in the 13 production and maintenance of these items, so too has the ability to repair, refurbish, and even recycle them. There are organizations and businesses that work towards refurbishment before recycling, however. One such group, known as Free Geek, works in different communities accepting laptops and PC’s that might normally end up in landfills. The donations are taxdeductible and the volunteers are very adept at determining what units will be eligible for refurbishment or will need to be recycled. Once it is determined that a unit is ok for refurbishment, people who participate with the organization are taught how the different components work, what needs to be replaced, and end up building their own free computer. With this set-up, Free Geek spends no money on the breakdown and rebuilding of computers, and citizens who might not normally have access to computers learn how they work and get to walk out with a free working device. Any items that Free Geek take in that need to be recycled are done so ethically and properly, and other items which cannot be integrated into refurbishment are sold in the community to fund future operations (Fosdick). This is just one example of how a motivated group of people can get further life out of electronic devices and keep items from the landfill. By doing just a little investigation, the average consumer can make an impact on e-waste proliferation by selecting a correct route for their used electronics. Refurbishment represents the most effective process in reducing electronic waste. A large number of devices are simply discarded that either work perfectly fine, or need a small repair to continue their life. Refurbishing an electronic device allows less natural resources to be used, and allows an extended life for the device, possibly in the hands of someone who 14 normally wouldn’t be able to afford it. Although this process does represent some of the exportation of discarded electronics, these types of items at least represent something of value that a developing country could use. If these devices were segregated here in the U.S. and only those items that could be refurbished were shipped overseas, this would reduce the amount of electronics shipped by 75%, and allow the brokers there to spend more time repairing and reselling products instead of sifting through junk to find 1 or 2 usable items. As bad as it sounds, recycling of electronic devices has become the real problem for the fate of e-waste and its legacy. Proper and ethical recycling is still in its infancy in the U.S., and because we are still developing good practices there is difficulty in developing profitable recycling of electronics. Many of the recoverable materials such as plastic casings and internal components do not fetch much on the market. There are also so many different types of materials that no one recycling center can afford to have all of the processes for removing them and selling them. As long as there is an available market overseas for accepting and processing electronic waste at a discounted cost, American businesses will continue to send them there. Our job as consumers is to demand a better system. Pressure on manufacturers of electronics has resulted in less diversity of materials in the devices, and less hazardous materials. If the additional cost of proper recycling here in the U.S. were spread out over all consumers buying electronics, it shouldn’t raise the price all that much. What could be proposed is a surcharge or tax on electronics, with the proceeds being used to subsidize the recycling industry in processing the items and developing new technologies. A sales tax of as little as four to six percent would bring in an incredible amount of money, considering the amount of devices that are sold in this country alone. Poorer countries would have to find another way to make 15 money, but in the long run protecting their environments from our waste will save them a huge amount of money in itself. Finally, simple disposal of electronics needs to be reduced and stopped. Over the past 40 years the U.S. has made great strides in increasing the recycling rates for all sorts of solid waste. E-waste just represents the next step in that process as education and awareness are implemented to change culture and habits. Most states have established specific pick-up days for electronics, placed restrictions on what can be thrown away, or made available lists of organizations that collect e-waste. The EPA has also worked on public service announcements and other media that explain the impacts of e-waste, and how to curb its effects. Public awareness has also spawned groups whose sole purpose is to pressure manufacturers and retailers of electronics to be more responsible with the production and proper processing of these devices. It is now beneficial for a retailer to offer to take back used devices and process them in an ethical manner as it increases return business, and builds trust with their customer base. As with most environmental issues, the solutions are not easy or simple. The most important steps that need to be taken are increasing responsibility and accountability with the people who are most involved in the production of e-waste: the end consumer. We also need to incentivize keeping electronic refuse within the borders of our country, and penalize those who try to send it abroad. Although the markets exist for used electronics and recycling services in developing countries, the current situation allows for too much abuse and irresponsibility. As regulations continue to become stricter and require more accountability on 16 the parts of consumers and industries, there will continue to be a desire to circumvent the system at the cost of another country’s environment and the health of its people. Addressing the problem with incentives and assistance will do much more than regulations that put a stranglehold on economic growth. Businesses will tend to do what makes the most profit. By making it less profitable to shift the problem to another part of the world we can influence the market and improve the environment globally. Consumers will continue to be the most important factor in solving this issue for years to come. Continuing to educate and raise awareness should be the number one priority for government agencies and those invested in the e-waste recycling and refurbishing businesses. In addition, closing the digital divide will also ensure a discontinuation of the environmental injustice caused by e-waste. 17 Works Cited Coby S.C.
