Status of e-waste recycling alarming system is imperative

Reform and opening up, with the rapid economic and social development of the continuous improvement of living standards, household appliances and electronic products production, consumption and the prevalence increased year by year, gradually speed up the replacement rate, while the electronic waste caused by the rapid increase in pressure on the environment has become increasingly prominent. According to the National Bureau of Statistics, the current social ownership in our TV sets to 3.5 million units, refrigerators,
Washing machine
Respectively 1.3 million and 170 million units. Most of these appliances in the late 20th century and into the home of 80 years, according to the service life of 10 to 15 years, from 2003, China will have at least 5 million per year

TV sets, 4 million refrigerators, 5 million washing machines to be scrapped. In recent years China

Surge in consumption. Computer ownership in the current society of nearly 2,000 million units, about 190 million mobile phones, and computers, mobile phones updated much faster than household appliances, there are about 5 million computers on the 10 million mobile phones have entered the phase-out period. According to the State Environmental Protection Administration estimates that e-waste in China produce about 111 million tons, or about 1% of the total garbage. As the various types of household electrical appliances out of discarded electronic products faster, forming a large number of e-waste, not only become a serious social burden, waste a lot of resources and energy, but also caused serious environmental impacts.

However, there is concern that at present China is still not formed a specialized focus on e-waste recycling, handling, processing of the system. According to Ministry of Information Industry of the survey, the main flow of domestic e-waste channels are two: First, through the hawkers and recycling of used appliances, available through second-hand market, the maintenance package, sold to the
Countryside
; Can not use the (
Glass
, Plastic, etc.), dismantling sell; the rest discarded as ordinary garbage. Second, by the dismantling of illegal small workshops, Zhejiang, Fujian, Guangdong coast some farmers use simple tools, with
Sulfuric acid
In the e-waste in refining gold, silver,
Copper
, Tin and other precious metals. This can not satisfy the "reduction, recycling and sound" of processing requirements, disassembled acid and toxic substances to landfill or into the ground, serious pollution of land and underground water, causing the second of environmental pollution, ecological cause enormous damage to the environment. Therefore, in order to solve e-waste pollution, recycling of valuable resources, construction, professional, integrated focus on recovery, treatment system is imperative.

And other electronic office products processed by the focus, 60% to 80% can be separated into high purity of renewable resources. According to analysis, 2 tons of waste home appliances recycling 1 ton of iron availability, with the same high-grade iron ore; recycling 14 tons of waste household appliances you can get 1 ton of copper, copper extracted from the 200,000 tons Ze Xu (China needs 300 000 t); random collection of 1 ton of electronic boards, you can isolate the 286 pounds of copper, 1 pound of gold, 44 pounds of tin, only the value of 1 pound of gold is 6000 U.S. dollars; the accumulation of 1 ton of waste hand-

Pool, can be extracted from 100 grams of gold.

According to information provided by national authorities, recovery of renewable resources in the developed countries could reach 250 billion U.S. dollars, steel 44%, copper 62%,
Aluminum
20%, lead 40%, 75% of paper comes from renewable resources. However, According to the survey, China did not make use of recyclable and renewable resource value of more than 300 billion yuan, about 500 tonnes of waste each year

And a lot of waste plastics, waste glass is not recycled. In fact, compared to China and the world average, on the one hand, people may use a lower share of resources, mineral resources and share of only 58% of the world average; the other hand, destruction and waste of resources and very prominent, and resource productivity the rate of recovery and comprehensive utilization rate lower. The total recovery of mineral resources in the country only 30% of associated mineral resources comprehensive utilization rate less than 20%, far below the 50% of the world average.
