The 20th century was marked by the impact of information and communications technology ICT on social and economic development. The digital revolution, started in the late s, led to explosive production of and extensive use of electronic and electrical equipment — one reason that has made the information society affordable.
This chapter addresses the health and environmental risks associated with electronic waste e-waste from cradle to grave. The issues of e-waste generation, handling, disposal, and export to underdeveloped nations for reuse, recycling, and disposal are discussed. The pattern of environmental injustice in the movement of e-waste especially from the global North to the global South of the world is addressed. First, the chapter presents selected definitions of e-waste, sources of e-waste, and some background literature concerning the growth and diffusion of electronic devices around the world in recent decades. The emergence of e-waste as a global environmental problem of immense proportions is introduced. Second, a conceptual understanding of what constitutes e-waste is provided, including a model of e-waste flow from the generators to processors and from environmental contamination to human health risks. Third, contrary to the image of electronic devices as environmentally benign, lean, and clean, the multitudes of toxic substances neatly packed inside these devices that pose a serious health threat to the public and the environment once discarded and dismantled are emphasized.
Electronic waste or e-waste describes discarded electrical or electronic devices. 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. Electronic scrap components, such as CPUs , contain potentially harmful materials such as lead , cadmium , beryllium , or brominated flame retardants. Recycling and disposal of e-waste may involve significant risk to health of workers and their communities. E-waste or electronic waste is created when an electronic product is discarded after the end of its useful life. The rapid expansion of technology and the consumption driven society results in the creation of a very large amount of e-waste in every minute.
The World Has an E-Waste Problem
Khurrum S. Over the recent past, the global market of electrical and electronic equipment EEE has grown exponentially, while the lifespan of these products has become increasingly shorter. More of these products are ending up in rubbish dumps and recycling centers, posing a new challenge to policy makers. The purpose of this paper is to provide a review of the e-Waste problem and to put forward an estimation technique to calculate the growth of e-Waste. Over the past two decades, the global market of electrical and electronic equipment EEE continues to grow exponentially, while the lifespan of those products becomes shorter and shorter. Therefore, business as well as waste management officials are facing a new challenge, and e-Waste or waste electrical and electronic equipment WEEE is receiving considerable amount of attention from policy makers.
The Global E-Waste Monitor reports a record 59 tons of e-waste, and predicts a rise to 81 tons by Even non-techies can be reliant on many pieces of technology as they navigate the day: Smartwatch, smartphone, earbuds, tablets, laptops, car charger, and more. And while there's the unicorn who proudly holds up their still-working iPhone 4, today's tech has a shelf life. As technology grows faster and less expensive, increasingly more people have any combination of tech gadgets. Eventually, most tech becomes e-waste, a fast-growing worldwide problem.
Global e-waste is up 21% in 5 years, causing serious environmental harm
Some of the work undertaken by UNU-Step included tracking global flows of e-waste, the Person-in-the-Port project in Nigeria, optimization of an e-waste dismantling facility in Ethiopia and the development of a tool to help gather information on volumes of e-waste generated within countries and exported to others. Managing the e-waste created by an increasing amount of computer and telecommunication equipment is important to the Ethiopian government, and many international partners have worked in Ethiopia to help address this concern. The project also strengthened the capacity of a demanufacturing facility to process e-waste in Addis Ababa.
A s a tech-hungry nation flush with cash gets ready to upgrade to the next generation of lightning-fast 5G devices, there is a surprising environmental cost to be reckoned with: a fresh mountain of obsolete gadgets. About 6 million lb. Pallets of once beloved but now outdated devices, like smartphones with only an 8-megapixel camera or tablets with a mere 12 GB of storage, arrive here daily.
