E-waste - UN urges smart technologies to protect our health - UN News So-called e-waste from products such as old computers, printers, mobile phones, pagers, digital photo and music devices, refrigerators, toys and televisions are set to rise sharply in tandem with the growth in sales in countries such as China and India, as well as in the continents of Africa and Latin America over the next ten years, according to a report issued by the UNEP. The study, Recycling from E-Waste to Resources, launched at a meeting among hazardous waste experts in Bali, Indonesia, predicts that by 2020 e-waste from old computers will have jumped by 500% from 2007 levels in India, and by 200% to 400% in South Africa and China. Meanwhile, e-waste from old mobile phones will be seven times higher in China and 18 times higher in India. At the same time, most e-waste in China is improperly handled, much of it incinerated by backyard recyclers to recover valuable metals like gold practices that release steady plumes of far-reaching toxic pollution but yield very low metal recovery rates compared to state-of-the-art industrial facilities. “This report gives new urgency to establishing ambitious, formal and regulated processes for collecting and managing e-waste via the setting up of large, efficient facilities in China,” UNEP Executive Director Achim Steiner said. “China is not alone in facing a serious challenge. India, Brazil, Mexico and others may also face rising environmental damage and health problems if e-waste recycling is left to the vagaries of the informal sector. “In addition to curbing health problems, boosting developing country e-waste recycling rates can have the potential to generate decent employment, cut greenhouse gas emissions and recover a wide range of valuable metals, including silver, gold, palladium, copper and indium. By acting now and planning forward many countries can turn an e-challenge into an e-opportunity.” The report, issued at a conference comprising parties to the Basel, Rotterdam and Stockholm Conventions dealing with hazardous wastes ahead of UNEP’s Governing Council meeting in Bali, ‟“In addition to curbing health problems, boosting developing country e-waste recycling rates can have the potential to generate decent employment, cut greenhouse gas emissions and recover a wide range of valuable metals, including silver, gold, palladium, copper and indium. By acting now and planning forward many countries can turn an e-challenge into an e-opportunity.” recommends that countries establish e-waste management centres of excellence, building on existing organisations working in the area of recycling and waste management. Turning Waste into Wealth – UN News World Habitat Day focuses on cleaning up cities. The technology also provides an opportunity for newer, rapidly-growing cities in developing countries to “leapfrog” older cities, by taking advantage of the latest solutions and avoiding more established, but less efficient methods. Using these tools effectively, the United Nations (UN) Chief recently said they can help us build well-planned and smartly managed cities, which can steer us towards inclusive growth, and low-emission development. The potential benefits of frontier technologies for developing countries are outlined in the 77
