The United Nations estimates that roughly 20 to 50 million tons of e-waste are generated worldwide each year, comprising more than five per cent of all municipal solid waste. Mobile phones contain inorganic materials, metals and plastic that pearl earrings can be recycled as part of the sustainable e-waste management. “The battery is removed from the handset and metals like gold, titanium and copper can be reused once they are treated. “The plastic can be reused to make traffic cones and park benches. It is important for people to realise that wheat pearl up to 80 per cent of the device can be recycled,” said Ranta-aho. A UAE resident has more than two mobile phones on average but use only one. Recycling just one unused phone of all people can save nearly 80,000 tonnes of raw materials. EnviroFone, a mobile phone and e-waste collection campaign pearl earrings by etisalat, collected 40,000 mobile phones and 23 tonnes of other electronic wastes in the UAE in the beginning of this year. In 2008, 200,000 mobile phones and 52 tonnes of e-waste were collected.
