The electronic industry has been the largest and fastest growing manufacturing industry in the world for more than a decade. On the one hand, advances in technology have allowed economic growth and contributed to a steady improvement in people’s lives. At present most individuals and businesses are dependent to a significant extent on computers and many other modern electronic inventions. On the other hand, the side effect of such a rapid pace of technological progress is the growing number of electronic wastes, particularly in the industrialized nations.
Electronic wastes, or e-wastes, include all home and business electronic appliances such as televisions, monitors, computers, audio and stereo equipment, fax and copy machines, cellular phones, video cameras, etc that are no longer wanted.
The fast evolution of technology has continuously led to decreased product prices that have discouraged upgrading or repair and increased “the demand for new products and the disposal of old ones” (Manalac “Electronic Waste: A Threat In The Future”).

“ This writer never make an mistake for me always deliver long before due date. Am telling you man this writer is absolutely the best. ”
About 400 million units of unwanted electronics equipment are discarded every year, and this figure is expected to reach three billion units by 2010.
According to various estimates, in the United States alone over 200 tons of electronic wastes are sent to landfills and incinerators every year which already constitutes from 2% to 5% of the US municipal solid waste stream. Moreover, this volume of e-waste is rising by 3% to 5% per year (“Harmful Effects”). Obsolete personal computers and televisions with cathode ray tubes present the most serious problems in the matter. It is estimated that over 500 million computers will be discarded between 1997 and 2007, and this will create more than six billion of plastic and over 1.
5 billion pounds of lead waste.
Cellphones pose a problem, too. They are used, on average, for just 18 months before being disposed of and every year around 150 million cellphones are discarded now. As regards rechargeable batteries – their use has increased nearly by 75% since 2000 (Allbritton “Desktop Recycling”). When discarded electronic wastes are improperly recycled or just dumped into landfills, they pose a serious danger to the environment and human health because of harmful materials that they contain such as lead, mercury, arsenic, cadmium, selenium, flame retardants, etc.
“Page # 2” When those substances are released into the environment they contaminate water, land or air and also affect coronary, respiratory, nervous and skeletal systems in the human body (“Harmful Effects”). Even if the dumping problem does not seem so bad in the United States yet, it is environmentally disastrous in certain third world countries such as China, India or the Philippines to which about 50% to 80% of US e-wastes are sent (“Harmful Effects”).
Due to cheap labor, it is more economical for American recycling companies to ship e-wastes to poor nations instead of processing them under the strict hazardous waste standards which exist in the United States (Allbritton “Desktop Recycling”). Besides, the practice of dumping toxic materials overseas has been “actively encouraged by the US Government”. At present, it is the third world countries who are suffering with environmentally problems. However, shipping American e-waste overseas only postpones the problem of discarded electronics at home (“Electronic Waste”).
All those poor countries lack environmental standards, and people who work at dumping grounds there just break open plastic cases and “burn the PVC cables over an open flame” releasing pollutants into the air. Acid they use to recover small amounts of precious metals is usually dumped into the nearby rivers (Allbritton “Desktop Recycling”). Beside waterways, the highly toxic remains are also piled on farm land or the roadside. It has been found that lead levels in some rivers are 190 times higher than levels that are acceptable by the World Health Organization (“Harmful Effects”).
It is obvious that all countries in today’s fast moving world are interrelated in various ways. So if the practice of dumping e-waste overseas is not prohibited in the near future, those short-term benefits that are currently gained by American Government will be turned into serious global environmental problems. And it might be too late then to solve these problems which will definitely affect our health and living environment. It is clear that electronic waste is with us to stay at least for many decades to come and it is likely to continue growing in volume.
E-waste is already a serious environmental and health problem in some regions of the third world countries where it is dumped in huge quantities. Sooner “Page # 3” or later American recycling companies will loose those overseas dumping grounds and US landfills will be steadily increasing in volume. If there are no important programs in place that can divert this e-waste from landfills, our environmental problems will be getting worse and worse, which, in turn, will affect the health of our citizens.
Serious actions have to be taken by the US and other industrialized countries’ governments in order to prevent the problem of e-waste from developing into an environmental disaster in the future. However, there are also many ways that every person can do to help reduce the impact of electronic waste on our living environment and the Earth itself. One of “the environmentally friendly options” includes trade in or exchange of equipment. Many producers of electronic equipment have special trade-up programs which allow consumers “to trade in their old equipment” when they buy new equipment.
Another way to improve the situation is to donate the equipment which is still in good working order to a local school, church, shelter or other non-profit organizations that are willing to accept used electronics donations (“Recycling Used Computers and End of Life Electronics”). One more option is to try repairing or upgrading the old equipment before sending it to a landfill. In case the old equipment is not in working order, it is possible to have it salvaged for parts which can be then used to “build or repair other systems”.
Electronic technology is a foundation of modern-day society. It plays an essential function in our everyday lives. Significantly throughout the world, electronic innovation has actually ended up being a staple in day-to-day living. From interaction, harnessing resources, to getting and sharing knowledge, electronic devices plays a vital role in the fundamental function of society. Nevertheless, as electronic equipment grows in number due to the improvement of technology, so does electronic wastes. E-Waste refers to electronic items nearing completion of their beneficial life that includes computers, printers, scanners, or any electronic items.
Today, the world has been accepting the age of technological modifications. Such modifications are adopted by numerous organisation establishments particularly Web Cafes; leading them in changing obsolete electronic devices to more recent ones, creating big loads of e-wastes, which in turn requires the challenge of having a proper e-waste management.
For circumstances, sixty percent (60%) of people interviewed in Congo, especially internet café staff and owners, said that they did not understand that ewaste has unfavorable impacts on health and the environment. Due to the absence of policy on management of this classification of waste, people tend to blend ewaste with routine trash and throw it in public bins. The waste is blended and taken to the land fill with no pre-sorting (Niombo, 2010). Internet Cafes need to have a special collection system, and a management alternative to handle these wastes correctly for a sustainable advancement. Without adequate e-waste management, possible hazards to health will take place and may threaten eco-friendly balance.
To combat the issue, a study is conducted pertaining to E-waste Management Practices among Internet Cafes in the City of Dumaguete. This study would determine the e-waste management practiced by internet cafes and the information will be utilize in extracting valuable lessons from the study in order to improve the effectiveness of the practiced e-waste management methods on Internet cafes. From the outcome of this study, a better way of management would be developed, a systematic management would be made and would be adopted in which it would lessen their burden by providing guidelines that includes recycling process, the application of 3R’s, Reduce, Reuse & Recycle which are stipulated & highly stressed in this research. It will also be used as the basis in creating an E-Waste Tracking System that will be implemented on respective Internet Cafes in the City of Dumaguete.

Review of Related Literature
This section contains background information and concepts that explains the existence of the problem and the possible connection between certain factors involved in the study. This would help the researchers identify and define issues that justify the need of studying the problem. This includes the definition of e-waste and its related issues that explain the existence of a proper e-wastes management. This also includes the e-waste management by different countries. But before going though e-waste management, there should be understanding pertaining to e-wastes.
Electronic waste, or e-waste, is a term for electronic products that have become unwanted, non-working or obsolete, and have essentially reached the end of their useful life. Because technology advances at such a high rate, many electronic devices become “trash” after a few short years of use. In fact, whole categories of old electronic items contribute to e-waste such as VCRs being replaced by DVD players, and DVD players being replaced by blu-ray players.
E-waste is created from anything electronic: computers, TVs, monitors, cell phones, PDAs, VCRs, CD players, fax machines, printers, etc. Additionally, e-waste is any refuse created by discarded electronic devices and components as well as substances involved in their manufacture or use (Rouse, 2007). According to Johri (2008), E-waste is one of the fastest growing waste streams in the world. Some of the notable items under this category include personal computers, mobile phones.
The technical innovations and rapid change in the models of these entities have generated huge quantum of wastes. With increasing level of penetration, supplemented by high rate of these equipments, the generation of electronic wastes is expected to rise. Kishore (2010) affirmed that the quantity of “e-waste” or electronic waste has now become a major problem. Disposal of e-waste is an emerging global environmental and public health issue, as this waste has become the most rapidly growing segment of the formal municipal waste stream in the world. Sales of electronic products, most notable information technology and telecom (IT) equipment have steadily increased over the past twenty years (Brown-West, 2010).
Salleh (2013) revealed that the director of the Croucher Institute for Environmental Sciences, Professor Wong said that "he would call e-wastes as a global time bomb, referring to the growing pile of waste produced by old mobile phones, computers and other electronic devices. As much as 50 million tons of hazardous e-waste is being produced a year and only a small fraction of this is safely disposed. In a personal computer, for example, there may be lead in the cathode ray tube (CRT) and soldering compound, mercury in switches and housing, and cobalt in steel components, among other equally toxic substances (Rouse, 2007). In many instances, the only visible part of an electronic product is its outer shell. Unless that casing is broken, we rarely see the myriad circuit boards, wiring and electrical connections that make the device actually function. But it's those inner mechanical organs that are so valuable and so toxic.
A whole bouquet of heavy metals, semimetals and other chemical compounds lurk inside your seemingly innocent laptop or TV. E-waste dangers stem from ingredients such as lead, mercury, arsenic, cadmium, copper, beryllium, barium, chromium, nickel, zinc, silver and gold. Many of these elements are used in circuit boards and comprise electrical parts such as computer chips, monitors and wiring. Also, many electrical products include various flame-retardant chemicals that might pose potential health risks. Arsenic may disrupt cell communication and interfere with the triggers that cause cells to grow, possibly contributing to cardiovascular disease, cancer and diabetes if someone is exposed in chronic, low doses. (Toothman, 2001). With these issues pertaining to e-wastes, particularly on health, there is a pressing need to address ewaste management.
The unsafe and environmentally risky practices adopted poses great risks to health and environment (Shiga, 2007). E-Waste management provides guidelines for selecting the most environmentally desired methods for managing a waste stream. E-waste collection programs need guidelines to assure that products are managed in a way that protects public health and the environment and conserves valuable resources. The best option for dealing with E wastes is to reduce the volume. Designers should ensure that the product is built for re-use, repair and/or upgradeability. Stress should be laid on use of less toxic, easily recoverable and recyclable materials which can be taken back for refurbishment, remanufacturing, disassembly and reuse. Recycling and reuse of material are the next level of potential options to reduce e-waste.(Recovery of metals, plastic, glass and other materials reduces the magnitude of e-waste.
These options have a potential to conserve the energy a nd keep the environment free of toxic material that would otherwise have been released (Joseph ,2007). E-Waste issues needs special policies with strict enforcement taking into account its special nature. These policies need to address collection, processing, disposal and recycling of ewaste. These policies also need to target education and public awareness about the dangers of ewaste for a better understanding of how to dispose of it, due to a general ignorance of its problems Skills transference should also be promoted and practical proposals created to deal with old technology once it reaches its end of life. Legal measures should therefore be accompanied by capacity development programmes.
Government and development partners need to develop a clear national policy for the collection and management of ewaste, encourage private investment in recycling that takes into account both environmental and human health, implement programmes to educate the public about ewaste management. Civil society needs to develop projects to raise awareness about recycling and the dangers of ewaste (Burrell, 2012). Actions to be generated are arranged into three main categories: first, a management program to help properly manage e-wastes; second, education and research to help further the knowledge of e-waste management and build upon the knowledge gained through the management program to create national policy for e-waste; and finally, a project core to provide guidance and unity of the entire e-waste project.
According to a report put out by the United Nations Environmental Programme (UNEP) entitled “Solving the E-waste Problem”, the main steps in the recycling chain of proper management include Collection; Sorting/Dismantling and Pre-processing (includes sorting, dismantling, and mechanical treatment which can utilize high-tech or low-tech processes); End-Processing (includes refining and disposal).The effectiveness of the entire recycling chain depends on each step and how well the interfaces between steps are managed. (Utkucan, 2010). Prior to E-waste Management, “many of e-waste could be a new electronic item is purchased and after some time it becomes obsolete. Four options are then available to the owner of the equipment. It could be reused – possibly resold or reassigned to another user. Second, the original owner could store it.
Third, it could be recycled, or fourth, the equipment could be landfilled. Recycle and landfill are the end points” (Peralta, 2006). Several countries have their way of managing these e-wastes. According to Babington (2010), the Department of Environment (DOE) in Malaysia has placed 309 recycle bins to collect used hand pones and its accessories in various locations such as supermarkets, universities, government offices, but majority of the residence are yet to comply due to limited awareness. Subsequently, Department of Environment (DOE) have encouraged the establishment of e-waste recycling facilities by private sector and since then 141 recycling facilities have been licensed by DOE.
The need for e-waste recyclers at different MRF and DOE to champion e-waste management cannot be over emphasized. In China, 88.843 million tons of recyclable waste were traded and recycled at a total value of 34.85 billion USD (Asiimwe, E.N. n.d.). In 2008, an e-Waste Association of South Africa (eWASA) was established to help establish an sustainable environmentally sound e-waste management system for the country (Waste management world, 2013). Land filling is the predominant by means of disposal of MSW now in China with approximately 90% of China’s total MSW is disposed of in sanitary and simple landfills (Dong, 2011).
The city of Guiyu with its surrounding towns in the Guangdong, a region of China is the largest E-waste recycling site in the world. Recycling has been occurring since 1995. Guiyu has a population of 150,000, most of which are immigrants. Nearly 80% of families have members who have engaged in E-waste recycling operations (Robinson, 2009). Moreover, all the recycling is being carried out by the informal sector. It is estimated that 120,000 urban poor from the informal sector are involved in the recycling trade chain in Dhaka city. 15% of the total e-waste generated in Dhaka (mainly inorganic) equates to 475 tons recycled daily.
Of this amount, only 20% to 35% is recycled, while the remainder is disposed of in landfills, rivers, ponds, drains, lakes and open spaces (Hossain, 2009). On the other hand, Mexico has ratified the Basel Convention. UNEP cited Mexico as a country with great potential to introduce state-of-the-art e-waste recycling technologies because of its small informal-waste sector. In 2006, in cooperation with the US State of California, one of the few state-of-the-art electronic recycling facilities in Latin America was installed in Monterrey, the first major electronic recycling operation in Mexico.
Additionally, In Serbia, waste management infrastructure is seriously underdeveloped, with few regulated landfills. Large amounts of e-waste are being stored in warehouses and homes. There is also an active informal sector, consisting mainly of disadvantaged people such as the Roma. In general, collectors have low interest in e-waste due to its complexity and the lack of potential buyers; as a result, their top priorities include paper, plastic and scrap metals.
However, there are highly unorganized, informal e-waste recyclers who use rudimentary techniques such as burning cables to extract copper. These practices are unregulated, with no employment contracts (Lundgren, 2012). Above All, different countries have their way of managing their e-waste; basically comprising from the informal and the formal sector. In view of the issues caused by e-wastes, a proper e-waste management is a great challenge especially to those places that are not aware of the hazards of those wastes. There must be an implementation plan and regulated policies reading the disposal of e-wastes. With all mentioned practices in various places, recycling is the most commonly practiced by various places. Furthermore, regulations should be designed in conjunction with the establishment of formal recycling infrastructure, or any collection system towards a better e-waste management to ensure the safety and protection from threats posed by these e-wastes.
Review of Related Systems
This contains related studies conducted by different researchers and development of e-waste tracking systems to keep track the generation of e-wastes. This includes concepts about E-Waste Tracking systems developed by different countries in order to track the generation of e-wastes. As instance, Switzerland, the first electronic waste recycling system was
implemented in 1991, beginning with collection of old computer monitors; over the years, all other electric and electronic devices were gradually added to the system. The opportunity is to find better ways to manage our used and end-of-life electronics and avoid them ending up in landfills, and that is though e-waste management (Lanyard, 2000). Electronic Recyclers International (ERI) has launched a new tracking and transparency system that gives customers complete real-time access to the status of their organizational recycling efforts, the company says.
The MyTrackTech software gives organizations that recycle their electronic waste through ERI up-to-the-minute access to their accounts and allows them to schedule shipments, review reports, and customize their recycling tracking. The MyTrackTech software is the first comprehensive customer access portal of its kind in the industry (Shegerian, 2012). Department of Heritage and Protection (DHP) are developing a tracking system that an effective waste tracking system will be able to provide EHP with all prescribed information required by schedule 2 of the Waste Regulation. The information from any one waste handler should be able to be provided to EHP in batches.
The system must also be able to provide EHP with proof (equivalent to a signature on a form) that the information has been authorized by an appropriate person. Such authorization may include the use of a particular header for the data or a private key or password/code word (Department of Heritage and Protection, 2010). In the article “A Global Pinball Game: Tracking E-Waste” that there are two common fates for old electronics, recycling or reuse. To track the reuse stream, the team collaborated with World Computer Exchange, World Teach and the Peace Corps, which all send outdated computers to countries the developing world.
Forty donated netbooks were equipped with tracking software and labeled with stickers announcing that they recording their whereabouts. After arriving at their destinations, the computers send out location updates and snapshots of their surroundings every 20 minutes. With this data, the team is able to create a real-time visual narrative of these computers’ second lives in classrooms in Nepal and public libraries in Kenya.
“For the first time, you can actually see where your old laptop ends up and who is benefiting on a day-to-day basis from your donation (Foster, 2011). Environmental Protection Agency (EPA) collaborates with the United Nations University - Solving the E-waste Problem Initiative (StEP) to jointly address the e-waste problem in developing countries. EPA and StEP signed a cooperative agreement on this topic in November 2010. EPA and StEP are working collaboratively on developing a system for tracking global flows of e-waste, strengthening Ethiopia's efforts to manage e-waste and engaging with China on e-waste management practices (Adrian, 2003).
There are many related systems that are being developed in order to keep track of the flow of e-wastes coming from different sources. An e-waste management system should be implemented to avoid risks towards our health and environment. One way of having a proper e-waste management is the creation of an e-waste tracking system that provide users to keep track of the e-wastes disposed by Internet cafes in the City of Dumaguete.
THE PROBLEM
