And so are generally referred to as "


E-waste


. "In recent years, management in place, and a number of family workshops" underground facility "illegal dismantling them for recycling, often caused by toxic substances pollute the air, soil and groundwater, and even a serious ecological disaster.





However, the reporter recently Export Processing Zone in the North Sea has seen another scenario: that the regular "e-waste" recycling enterprise, plant clean, elegant environment, water


Cycle


Use, split neatly down the classification of packaging materials, and each procedure on the dust, sewage, noise and other strict technical rules, to avoid environmental pollution; the local environmental protection department once every three months for monitoring to ensure that its "safe production" .





Recent years, with environmental consciousness, people are increasingly sensitive to environmental issues, and many media "e-waste" recycling due to contamination of the exposure of the electronics recycling industry people the "disadvantages" With very good understanding, but have neglected the e-waste recycling law norms "benefit" of "renewable resources" industry had a bias. Some people think that recycling of waste electrical spin-off assembly of the product is "second-hand", in fact, the products manufactured are subject to stringent testing to ensure reliability and performance


Security


; There are many people informal manufacturers and illegal "underground factories" on equal footing as a dangerous source of pollution, that should be shut out; will be under strict supervision in the customs that are foreign transfer of solid waste garbage imports, the actual of electronic solid waste import and export trade is a normal one, and is implementing international conventions, "an extension of the production company responsible recycling," the relevant requirements.





Environmental protection is a science, for fear of pollution, for "electronic waste" indiscriminate white Yigai excluded attitude, undoubtedly runs counter to the spirit of science. According to technical personnel, "e-waste" is a renewable resource of huge value. To waste mainframe computer, for example, copper, aluminum,


Steel


, Plastics account for about 90% by weight, of which 54% of steel, copper and aluminum 20%, plastics 17%, circuit board also contains valuable gold, silver, palladium and other metals; in retirement mainframe, split screen treatment The scraps, recyclable

Treated wastewater recycling loop blizzard, because useful substances containing lead, overseeing the re-pricing is still up to several hundred dollars per ton. China is the home appliances and electronic products producing countries, many foreign-owned or joint venture factory in China, products are exported, means that large quantities of iron and steel, rare metals, chemical materials and energy are spent, and the "e-waste" recycling, the manufacturing of these products native resources and energy saving is undoubtedly effective.





China's per capita resources are limited, as an important part of recycling economy, renewable resources, industrial development is an important guarantee for achieving sustainable development. Therefore, we have the responsibility to promote environmental protection and rational ideas and concepts, scientific knowledge to help people "e-waste" recycling of value and meaning, which is no doubt the development of China's renewable energy industry has a positive effect.
