Digital battery

Waste batteries may be small, but have major damage. However, due to pollution, waste batteries as waste, air and water pollution, as would any sensory think she has a great hidden, so they do not received due attention. At present, China has become the production and consumption of Laptop battery power, pollution of batteries is an urgent need to solve a major environmental problem. Today we are releasing three consecutive editions of relevant reports and the relevant government departments want people to attach importance to environmental pollution caused by batteries, the joint action for the recycling of waste batteries to face advice and suggestions to encourage the production and consumption, “Green Battery” to develop relevant policies.

 

Batteries are our daily lives, using one of the most commonly used, from cameras, tape recorders, calculators, clocks and electronic pagers, electronic dictionaries and handheld computers, are inseparable from the battery. China is a production of dry batteries and consumer country, year, production reached 15 billion of first place in the world, consumption of 70 million, an average of all Chinese people eat five batteries per year.

 

For years, China’s production of dry batteries, it is necessary to reach a toxic — mercury or mercury compounds. Alkaline batteries from China in the mercury content of 1 to 5%, 0.025% neutral dry-cell batteries, dry 40Y6797 batteries annually for the production of tens of tons of mercury amounted to much.

 

Mercury is our so-called “Mercury”. Mercury and its compounds are toxic, the scientists found that mercury neurotoxicity was evident in most of the endocrine system, immune system, also have side effects. The 20th century took place 50 years in Japan shocked the world of public nuisance disease — Minamata disease is caused by mercury pollution.

 

Over 40 years in Japan, a coastal city in southern Kyushu — city of Minamata, the local population, it is a strange disease. Patients began to slurred speech, unsteady gait, limb paralysis, cramping body of last resort, mental disorders, died of torture in pain. Later, with people infected with diseases more and more, even the cats and birds have experienced the same symptoms. Later, medical workers and marine fish of the deceased in the body of toxic methylmercury have shown that people who consume contaminated fish poisoning. After investigation, the local industries in Japan original nitrogenous fertilizer to perennial mercury from Minamata bay containing wastewater discharged into sea by mercury pollution, seafood from local fishing contain high levels of methyl mercury.

 

Minamata Bay in order to restore the ecological environment, the Japanese government has spent 14 years invested 485 billion yen, the Minamata Bay mercury sediment dig deep 4 m, all clear. Meanwhile, in Minamata Bay, the entrance to the VGP-BPS2B establishment of a quarantine network will be contaminated in the bay of deep-sea fish were all caught up in landfills. Who attended the outbreak of Minamata disease Minamata, Japan, Mayor Masazumi Yoshii said with emotion: “After almost half a century of unceasing effort, we finally from the shadow of Minamata disease in out, and she built a new city of Minamata. I hope that the world has learned the lessons of Minamata disease in Japan, ignorance of the mode of production, the implementation of the civilized mode of production. ”

 

It is understood that in developed countries, have been eliminated mercury batteries, mercury batteries free at or low in mercury. In Sino-Japan Friendship Center for Environmental Protection of Japan as consultant experts Liu Xiu-Ming, the current generation of Japan and the use of mercury batteries are not due to mercury-free, the waste batteries to significantly reduce damage to the environment, and the costs of landfilling are also smaller s.

 

China from January 1, starting this year, has also introduced low-mercury batteries and mercury-free, in the new century, when the Dell Latitude D505 battery finally went into the lives of Chinese people green. However, the reporter learned that the majority of our consumers better understand the pollution of waste batteries are not too many people buy batteries often arbitrary and do not give priority to environmental compliance. As the manufacturer of the battery, battery production environment, need to improve the process equipment and raw materials, formulations, presumably to increase capital investment and production costs, companies are not very willing. At present, some business-to-cell “Restricted Mercury suggests that indifference, do not touch anything.

 

How to advocate for the protection of the environment, the concept of green consumption? How to promote greener production of green products? An interview with the Center for Environmental Science, Peking University Professor Ye Wenhu. He said the decision to choose what type of consumer goods, consumption patterns of people, while the consumption patterns of the public are an indication of the degree of social civilization. Must be directed by the publicity and education, to defend the people to choose a new concept of sustainable development, consumption patterns, buying green products in favor of environmental protection, consumer choice will push producers to improve the product. In addition, manufacturers should actively promote green products. What type of company products to stimulate consumption, which means the quality of entrepreneurs and corporate image? However, there are these two points is not enough, because the psychology of the consumer public, the general pursuit of a cheap BATBL50L6, green is not very important activity of the company, the Money is the first 1, the green is not the primary consideration. Therefore, we must submit to the Government, using economic means, legal and administrative steps to facilitate firms’ production and consumption patterns in public compliance with environmental requirements. The government’s behavior, market behavior (or behavior of enterprises) and public behavior of these three types of social behavior of man, the government acts in a dominant position.

 

Hazards of waste batteries and our response

 

The production of more garbage is so overloaded with the planet we live on an endless stream of pollution incidents, “junk Besieged City” has long sounded the alarm for us. How harmless, the reduction in resources was a priority. “Develop resources wrong” re in recent years, understanding of the garbage people. The implementation of waste separation and recycling of waste will be able to achieve the best possible use of turning waste into treasures.

 

On the size and weight, the batteries used in household waste are negligible, but its harmful effects is very large, batteries containing mercury, cadmium, lead and heavy metals. Highly toxic mercury, lead can cause neurological disorders, nephritis, etc. cadmium major cause of kidney and bone diseases - osteoporosis, osteomalacia and fractures. If the batteries mixed with household waste in the landfill, over time, leaching of heavy metals can contaminate groundwater and soil.

 

Using a hp PB991A battery in our lives is increasing rapidly, has intruded into our lives and work in all corners. WALKMAN, BP machines, mobile phones, cameras, calculators. Currently, the battery consumption of around 7 billion euros. It is predicted that the battery consumption in 2000 only BP machine reaches 1.55 billion. If you do not receive adequate treatment for these batteries will be directly or indirectly endanger the health of people. Implement and promote the activities of the separate collection of batteries used by people becoming more recognized and get more attention and more support and participation of dates with dispersed pollution, less centralized management.

 

Treatment and recycling of waste batteries

 

Many countries in Western Europe, not only in stores, but also directly on the street are equipped with a battery of special recycling boxes will be collected until the toshiba PA3285U-1BRS battery is charging up to screen out persons with specialized terminology watches, calculators and other small electronic devices of button cells, they generally do not contain mercury, mercury can be extracted to be used, then manually sort the cell nickel-cadmium batteries in France, a sample plant and nickel cadmium, nickel, and then used in the steel is reused in the manufacture of cadmium batteries.

 

Other types of batteries are generally transported to a particular toxic landfill of hazardous waste, this approach not only costs too (eg in Germany the cost of burying a ton of batteries up to 1700 points), but also wasteful because it is a lot of useful documents can be used for raw materials.

 

Switzerland has two specialized treatment and the use of companies of the former battery factory Batelieke adopt the method involves grinding the old battery, then sent to heat the oven, then we can extract mercury unstable zinc, when the evaporation temperature is higher, it is also precious metals. After the merger of iron and manganese in steel alloyed with manganese required. The plant can process 2,000 tons per year of waste batteries, 780 tons of ferro-manganese alloys available, 400 tons of zinc alloy and 3 tons of mercury. The other plant is extracted directly from the apple A1008 battery of iron and manganese oxide, zinc oxide, copper oxide and mixed oxide of nickel and other metals to sell as scrap metal directly.

 

However, the most expensive heat treatment, Switzerland also provides buyers with each of the battery charge a little bit of battery charges specific treatment, Magdeburg peri-urban areas of the country is building a processing “wet “devices, where the addition of lead acid batteries, the different types of cells were dissolved in sulfuric acid, then using the ion resin extracted from the solution of various metal objects, using materials obtained in this way pure as the method of heat treatment, thus a higher price on the market, but also a variety of substances contained in batteries 95% can be extracted. Wet processing is possible to avoid areas of sorting (because the sorting is a manual operation, will increase the cost). Magdeburg annual processing capacity of this device up to 7500 tonnes, which means that if the cost is slightly higher than the landfill, but valuable raw materials are not scrapped, it will not pollute the environment.

 

German Duarte vacuum heat treatment developed in France but also less expensive, but it must first sort the waste batteries, nickel-cadmium batteries, used batteries by heating in vacuum, where rapid evaporation Mercury can be recovered, then the rest of the ingredients field, using magnets to extract the metal iron powder and then extract the nickel and manganese remaining. This process of one tonne of waste batteries is less than 1,500 marks.

 

From what I have from a small start of each side is our motto. Care of the environment around them to participate in the classification of waste battery recycling is everyone’s responsibility and obligation. The behavior of individuals may be insignificant, but the strength of each of us raise enough to keep a civilization, a civilization with nature, sustainable development of civilization.
