Time occurred in 2805. Excessive destruction of the environment due to man, the earth floating in space has become a big ball of garbage. Has been moved to the spacecraft on the human beings on Earth had to send a large number of robots to clean the garbage. ThinkPad R50 battery ThinkPad R51 battery
The above story is the Hollywood cartoon “Robot Story”, the plot. Perhaps a bit exaggerated, but how to treat household waste increases, especially in the fastest growing electronic waste problem is indeed a human need to address an urgent problem.
Electronic waste by 4 million tones annually
As the electronics industry, the rapid development of e-waste in the soaring of the same, mainly a variety of discarded computers, communications equipment, televisions, refrigerators, washing machines and other electronic devices . ThinkPad R52 battery ThinkPad T40 battery
Held recently in Bali, Indonesia, the world series of conferences on the environment, UNEP Executive Director Achim Steiner warned that the various types of electronic waste increases to increase by about 40 million tones in number. In 2020, the world’s major emerging economies of e-waste will be in 2007 based on growth of 2 to 5 times. If no action is taken, these countries face the threat of environmental problems and health issues will become more severe.
El Steiner also stressed that the world should be actively recycling electronic waste, because it not only solve the various problems it brings, but also to reduce emissions of greenhouse gas emissions, but also to extract a large number of gold, silver, copper, palladium and other precious metals.
February 22 United Nations Environment Program released a report showing that annual expenditure on cell phones and the computer industry the world’s gold, silver and 3% of the total, 13% palladium, cobalt 15 %. At the same time, electronic products contain up to 60 types of metal components, some expensive, some are harmful, and some both. Sony VGP-BPS8 Sony VGP-BPS8A
The report also noted that e-waste generated each year in China totaled 2.3 million tons, second only to the United States of 300 million tonnes.
Great opportunities for recycling electronic waste
It is understood that in e-waste containing metals, particularly precious metals, its natural mineral content is several times or even hundreds of times, cost recovery and generally lower than the exploitation of natural beds.
For example, 1 ton of waste batteries from mobile phones can be extracted from 100 grams of gold, while the average gold bearing ore, the extraction of only 6 grams per tonne, many people but tens of grams, we can say that the old phone like a high gold content of gold ore.
In the printed circuit board, the more metal is copper, plus gold, aluminum and nickel, lead, silicon and so on, including rare species. PA3451U-1BRS PA3399U-1BAS
U. S. Environmental Protection Agency has confirmed that, using devices to waste at home instead of scrap steel can be further reduced by 97% of mine waste and 86% of air pollution, 76% pollution of water, 40% reduction in water consumption, less than 90% of raw materials, 74% of energy.
Toxic E-Waste
Electronic waste contains large quantities of toxic substances. If we set a 15-inch CRT computer monitor to contain cadmium, mercury, hexavalent chromium and brominated flame retardants and other harmful substances; computer batteries and switches containing chromium and mercury; computer components also contain arsenic, mercury and a variety of other hazardous substances such as televisions, refrigerators, mobile phones and other electronic products also contain lead, chromium, mercury and other heavy metals; laser printer and ink, etc. contain.
If the electronic waste in the desert, as a general or garbage, which contains heavy metals such as soil contaminated with lead and water will penetrate through plant, animal and human cycle of the food chain, causing possibly of poisoning, if to be burned, it releases a large number of dioxins and other harmful gases, threatening human health.

Winter Olympics medal, “e-waste” is
The just ended Winter Games 2010 Vancouver medalist electronic waste back home because of Winter Olympic medals are being used to extract metals from e-waste products.
It is understood that each block has a gold over 1.5% of the metals extracted from cathode ray tubes, computer parts, printed circuits and other electronic waste, each piece of bronze contains more than 1% of waste Electronic money also has a few dark electronic devices. The current Winter Olympics medal 140 thousand tons were used had to be integrated with e-landfill waste.
This is the first time the use of e-waste in the production of Olympic medals after medals were extracted from materials refining of minerals for commercial purposes. Satellite M50 battery Satellite M55 battery
