The Growing Crisis of E-Waste in Developing Countries
E-waste in developing and developed countries is when electronics are used, and they come to the end of their lifecycle. In contrast to other forms of waste, disposal of e-waste is specific, in order to protect humans and the environment from the harmful materials within; yet, impoverished countries do not have the resources nor funds to dispose of their e-waste properly.
Due to these countries improperly disposing of their waste, toxic chemicals then leak into the environment. In turn, health hazards arise. Below illustrates the prevalence of e-waste around the globe, recycling e-waste methods, impacts on human health and possible solutions eliminating excess e-waste in developing countries.
Presence of E-Waste
As technology advances exponentially around the world, consumers are constantly purchasing, upgrading, replacing and discarding their electric products. These products include computers, printers, televisions, cell phones, microwaves and washers, and dryers. Among the developed nations, the U.S. alone throws away 400 million tons of electronic items per year. In contrast, the European Union produces 8.9 million tons of e-waste and Japan produces 4 million tons. In total, the world produces 50 million tons of e-waste a year. It is an estimate that the world’s population will be discarding 60 million tons of e-waste by 2021.
The Differences in Recylcing E-Waste
Both developing and developed countries recycle their e-waste. In the formal recycling facilities of developed countries, electronics are disassembled, separated and categorized by material. They are then cleaned and shredded for further sorting. It is necessary hat recycling companies adhere to health and safety rules. They must also use pollution-control technologies to decrease the health and environmental hazards of handling e-waste.
This process is expensive, and to avoid spending the large amount of money needed to recycle e-waste formally, developed countries illegally ship their e-waste to developing countries for disposal. However, these developing countries do not have the means to recycle their e-waste formally. This is why countries, like Nigeria and Ghana, recycle their e-waste in informal ways.
Within developing countries, the informal e-waste sector includes sites where the extraction of valuable components of electronics happen using crude recycling and disposal methods. Families and individual workers depend on the extraction of valuable metals for an income. Metals include gold, silver, copper, platinum, palladium, lithium and cobalt.
Effects of Chemicals in E-Waste
However, these electronics also contain toxic heavy metals, such as lead, mercury, cadmium and beryllium. They also include polluting PVC plastic and hazardous chemicals like brominated flame retardants. These chemicals remain in electronics after extraction of valuable materials. They are burned, buried and discharged into waterways. Furthermore, these chemicals can find their way into the air, earth, water and ultimately into food.
Victims of contamination from e-waste in developing countries can experience both direct and indirect exposure. Direct contact with hazardous materials from e-waste in both formal and informal recycling settings can cause increases in stillbirths, spontaneous abortions, premature births and lower birth weights. They can also cause increases in mutations, congenital malformations, abnormal thyroid function, lead levels, decreased lung function and neurobehavioral disturbances.
Intervention in Recycling E-Waste
To decrease the amount of informal recycling of e-waste in developing countries, the United Nations created the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal. This organization bans the trading of hazardous waste between nations. Sadly, this policy fails to reduce informal recycling due to a general lack of governance and enforcement resources.
Renne Cho, a staff writer for the Earth Institute, lists six solutions in research that disposers should consider and practice globally to solve the global e-waste crisis. These six solutions are: designing better products, repairing and reusing devices already owned, extending producer responsibility, improving the recycling system, making recycling more convenient and making our economy more circular.
In regard to improving the recycling system, one strategy proposed to alleviate e-waste in developing countries is taking advantage of the large collection network of informal recyclers existing. Instead of eliminating this network, developing countries can utilize these companies to bring their collective e-waste to the formal sector.
Another solution to reduce the amount of e-waste illegally shipped to developing countries is for countries to invest in the resources necessary to provide the enforcement and supervision that will restrict the importation of e-waste.
The rapid rate at which consumers are now purchasing, upgrading, replacing and discarding electronics gives little reason to believe the e-waste crisis will end soon. More awareness about how e-waste is impacting the health of men, women and children in developing countries is necessary.
