Where Has All the E-Waste Gone?
Electronic waste has a large number, harm, potential value higher characteristic, with enormous quantity wide electronic waste recycling, recycling is to save resources, reduce waste production, protect the environment of the important measures, is an important content of circular economy.
Where Has All the E-Waste Gone?
With the further development of electronic technology, electronic products renewal cycle is shorten, increasing the amount of waste electronic products, caused serious harm to the environment. Relevant data show that 1.8 million tons of electronic waste are produced each year in Germany, France, 1.5 million tons, the whole of Europe is about 6 million tons.
According to the United Nations predicts that by 2017 the number of global e-waste will grow by 33%, more than 60 million tons. This will increase the toxic heavy metals such as lead, mercury, cadmium material into the soil and the risk of water supply, to form cause serious damage to environment and human health.
E-waste is rare and difficult to extract the rare metals and high value characteristics, so the recovery of waste electric and electronic products, and by renewable resources, can not only saving energy, recycling costs will also be much lower than directly from the ore smelting raw material, processing way of access to resources.
The results showed that: 1 t electronic board contained about 272.4 kg plastic, 129.8 kg, 0.45 kg of copper, gold, iron, 29.5 kg, 40.9 kg, 20 kg of nickel and lead 10 kg antimony, if can be recycled, that only 0.45 kg of gold is worth $6000. Therefore, the recycling of electronic waste has obvious social and economic benefits.
