There are currently 2.53 billion smartphone users in the world. Many of these electronic goods will get disposed quickly because first-time smartphone purchasers will upgrade to a new device within a year.
This increase in technology being used and produced presents a huge challenge for mankind and the environment – managing electronic and electrical equipment (EEE) waste, or e-waste. E-waste is the residue of EEE which reach the end of their life cycle either because they’re obsolete or users have upgraded to a better device. According to reports, India alone is predicted to touch 3 million tons of e-waste by the end of the year. One can only imagine how high the number is going to be worldwide.
The Health Hazards of E-Waste
E-waste contains like Antimony, Arsenic, Barium, Beryllium, BFRs, Cadmium, Chromium, Lead and Dioxins. When humans contract these toxins through water or air, they encounter health ailments like nosebleeds, seizures, development retardation in children, lung damage, high blood pressure, paralysis and skin cancer.
In many countries, especially emerging ones, e-wasteis disposed dangerously – either broken using crude tools, or burned. The former is risky while the latter releases toxic gases into the air. People performing these informal recycling practices (often in the unorganized SME sector) are most prone to their harmful effects, as are those who live close to dumping and disposal grounds.
How Urban Mining Can Help
The picture for e-waste management is not all gloomy. Done effectively, it can contribute brilliantly to urban mining.
Urban mining is the process of recycling valuable material like rare earth metals that were originally used in buildings and products.
In 2017, 1.57 billion smartphones were sold across the world.Research suggests that most of these devices contain about 50 times more gold than ores mined in the fields. Diving into specifics, the annual production of electronics uses 320 tons of gold and over 7,500 tons of silver. That’s a whopping 21 billion dollars’ value. But only 15 percent of it currently gets recovered.
