Question 2: How to deal with the waste batteries of mobile phones? The annual output of batteries in China has reached 654.38+0.4 billion ~ 654.38+0.5 billion, and the annual consumption is 9 billion, accounting for 654.38+0/4 of the world output. Waste batteries are discarded at will or buried improperly, which will cause the loss of harmful substances such as mercury, nickel, lead and chromium for too long. These harmful substances do great harm to underground water sources and soil. One No.1 battery is enough to make 1 m2 of soil lose its agricultural value, while one button cell can pollute 600,000 liters of water (which is a person's lifetime water consumption). Obviously, the recycling and disposal of used batteries must not be regarded as trivial matters. The harm of waste batteries is obvious to all. If we don't care about it, it will only be our own home that will get hurt in the end. Only when you, Qi Xin and I work together, starting from me, and making environmental protection a living habit, can the recycling of used batteries be carried out smoothly.
In China, the recycled waste rechargeable batteries must be sorted manually, and the nickel-cadmium batteries, nickel-hydrogen batteries and lithium batteries must be sorted out, then put into solid plastic packaging barrels, sealed and properly stored in special warehouses that are rain-proof, sun-proof, fire-proof and anti-theft. It is estimated that the collected waste batteries need to be temporarily stored for a period of time before they can be disposed of. The resource reuse of disposable dry batteries needs to reach a certain amount to be profitable. At present, the treatment countermeasure is to go to the sanitary landfill site for centralized and harmless landfill, and then take it out for recycling after the technology is mature.
It is understood that according to the service life of batteries and the update speed of electronic equipment, the number of discarded rechargeable batteries in Shenzhen every year is quite amazing, reaching 50 ~ 100 tons/year. Rechargeable batteries are the main pollution source of waste batteries. The lead they contain will damage the blood circulation system, digestive system and nervous system, while cadmium will cause serious diseases such as kidney damage and osteomalacia. Due to the potential heavy metal pollution and organic pollution of waste batteries, the pollution of waste batteries has aroused widespread concern from the public, media and environmental management departments in recent years, and developed countries have a very positive attitude towards the recycling of waste batteries:
Japan: Nomura Corporation of Hokkaido buys10.3 million tons of waste batteries from all over the country every year, accounting for 20% of the national waste batteries. Among them, 93% were collected by non-governmental environmental protection organizations, and 7% were collected by various manufacturers. In the past, mercury was mainly recycled, but at present, batteries in Japan no longer contain mercury, so we mainly recycle the iron case of batteries and the "black" raw materials inside, and develop and manufacture secondary products, such as one of which can be used for TV picture tubes.
Germany: Consumers are required to send waste dry batteries, button cell and other types of batteries to shops or waste recycling stations for recycling. Stores and waste recycling stations must unconditionally receive waste batteries and hand them over to manufacturers for recycling. Waste recycling stations and manufacturers generally only recycle batteries containing toxic chemicals such as cadmium and mercury, while 90% of ordinary zinc-carbon batteries and aluminum-magnesium batteries are buried or burned as domestic garbage.
Switzerland: There is a factory that treats old batteries by heat treatment. Grinding old batteries, then heating them in a furnace to extract volatile mercury and zinc, which are precious metals. Iron and manganese are melted to form ferromanganese alloy for steelmaking. The factory can process 2000 tons of waste batteries a year, and can obtain 780 tons of ferromanganese alloy, 400 tons of zinc alloy and 3 tons of mercury.
USA: It is the country with the most detailed legislation on environmental management of waste batteries. Not only has a perfect waste battery recycling system been established, but also a number of waste battery treatment plants have been established. At the same time, we will persistently publicize and educate the public, so that the public can consciously support and cooperate with the recycling of used batteries.
Question 3: How to deal with the waste batteries of mobile phones? At present, there is no special waste battery treatment plant in China, and even the recovered batteries are concentrated in landfill, which causes more pollution. Secondly, waste batteries are mostly low-mercury or mercury-free, which will not have much impact on the environment. Therefore, it is enough to treat them as ordinary garbage (I am quoting environmental experts). It should be noted that mobile phone batteries, button cell and rechargeable batteries are still highly polluting, so you must not throw them around! !
Question 4: How to deal with scrapped mobile phone batteries? Mobile phone batteries contain cobalt with extraction value and should not be simply classified or buried.
According to authoritative data, as of September 2002, there were nearly 200 million mobile phone users in China. Usually, a mobile phone can be equipped with two or four mobile phone batteries during its service life. In this way, what a huge number of batteries are needed for 200 million mobile phones!
In addition, mobile phones are frequently updated, and almost every mobile phone has a specific mobile phone battery to match it. After a mobile phone is eliminated, all accessories including the battery of the mobile phone will be "discarded". If one, ten, and one thousand pieces of used mobile phone batteries are littered around, it won't do much harm to the environment, then what about one hundred million pieces and one billion pieces?
Sun Zhongdang, deputy of Henan Provincial People's Congress and director of the Science Office of Zhengzhou Institute of Environmental Protection Science, said that there are three kinds of batteries for old mobile phones (referring to the previous models of color screen mobile phones, which are the easiest to update): nickel-cadmium batteries, nickel-hydrogen batteries and lithium batteries, and new mobile phones mostly use lithium batteries. But no matter what kind of mobile phone battery, it contains metal elements that can cause harm to the environment. However, unlike ordinary batteries, mobile phone batteries also contain cobalt with extraction value. Therefore, for the disposal of waste mobile phone batteries, we should actively recycle them instead of simply sorting and burying them like ordinary batteries. Recyclable symbols marked on mobile phone batteries of various manufacturers also indicate that recycling of such batteries is encouraged.
Huge quantity, backward processing
In Zhengzhou's Greentown Plaza, Dixintong, Eastcom Customer Service Center and Nokia Maintenance Center, the reporter interviewed 50 citizens randomly. Among them, 93.75% people shook their heads when asked about the disposal of used mobile phone batteries, and 80% people said that they would eventually throw away the used mobile phone batteries like ordinary garbage; Another 6.25% said they would sell their batteries and mobile phones to recyclers.
When the reporter asked, if there is a special recycling device for used batteries, would you like to put them in voluntarily? 62.5% people said yes; 12.5% people said that if there are some incentives, they can consider putting them in; Another 18.75% said that if there are many recycling devices and they are convenient, they are willing to place them at will.
At present, the second-hand mobile phone recycling market in Zhengzhou is very lively, and vendors holding "mobile phone recycling" signs can be seen everywhere. So can this market "absorb" used mobile phone batteries? The reporter inquired about Zhongyuan Road 10 old mobile phone recyclers. Nine of them said that the used batteries were useless and they were unwilling to buy old mobile phone batteries separately. Only 1 expressed willingness to buy used mobile phone batteries, but only a few "good goods" were better to sell.
Vendors who recycle second-hand mobile phones are reluctant to recycle mobile phone batteries. Are those mobile phone dealers and agents willing to recycle used mobile phone batteries? In some mobile phone shops near the north gate of Zhengzhou University, when reporters asked salespeople whether to recycle used mobile phone batteries, most people cast strange eyes. Someone even asked, "Of course, the used batteries are at home, and I have never heard of recycling." Some salespeople said that they had never met such a question from a customer, so they didn't want to recycle it.
In the whole interview, the reporter only found that two stores were willing to recycle used mobile phone batteries. One is a business hall in Erqi Road, China Mobile. They said they could use waste batteries to reach 20 yuan, but only if they bought the mobile phone batteries in this business hall. The other is Nokia mobile phone maintenance department. Unfortunately, however, in this maintenance department, a recycling box marked "mobile phone recycling, battery recycling and charger recycling" is full of snacks, and there is no mobile phone and its accessories, and this box seems to have been left out for a long time.
It can be seen from the above investigation by the reporter that at present, most of the used mobile phone batteries around us are garbage transfer stations, and some of them will flow into the hands of illegal vendors with old mobile phones, and then go on the market after renovation to deceive consumers.
Lack of correct recycling methods
When the reporter interviewed the environmental protection department, he learned that the used mobile phone batteries contain metal elements with extraction value. However, due to the lack of correct recycling methods and incomplete establishment of recycling channels, there are still many problems in the recycling of used batteries.
According to Mr. Wang of Zhengzhou Environmental Protection Bureau Information Center, Zhengzhou Environmental Protection Bureau was responsible for the earliest battery recycling, and now the environmental sanitation department is responsible for battery recycling. The sanitation department transported the batteries (all kinds) to the deep pit for landfill. At present, the state has not promulgated ... >>
Question 5: What should I do with the useless batteries on my mobile phone? Battery recycling has always been a big problem. The best way is to see which shopping mall has boxes for recycling batteries, put them in for unified management and unified floating recycling. It's a little troublesome, but it benefits the country and the people ~
Question 6: How to deal with used mobile phone batteries? 10 keep it for yourself, or make changes yourself, connect a small fan and light bulb, or throw it in the trash.
Question 7: How to deal with discarded mobile phones and batteries has been exempted. It is suggested that the collection should not be unified, but scattered and discarded.
Question 8: What should I do with the old mobile phone battery? Generally, there are boxes for storing used batteries in residential areas, or there are grids for storing batteries in roadside trash cans.
Question 9: It is said that used lithium batteries for mobile phones cannot be thrown away casually. What should be done? How to deal with waste batteries simply and environmentally? 1 handed it over to Zhong Bai No.2 Neighborhood Committee. There seems to be an activity to recycle old batteries as gifts. Give it to the recycling bin. Harm of waste batteries: The harm of waste batteries is mainly concentrated on a small amount of heavy metals, such as lead, mercury and cadmium. These toxic substances enter the human body through various channels, and long-term savings are difficult to eliminate, damaging the nervous system, hematopoietic function and bones, and even causing cancer. Lead: diseases such as nervous system (neurasthenia, numbness of hands and feet), digestive system (dyspepsia, abdominal cramps) and blood poisoning. Mercury: Mental state change is the main symptom of mercury poisoning. Rapid pulse, muscle tremor, oral and digestive diseases. Cadmium and manganese: mainly harm the nervous system. Ways for waste batteries to pollute the environment: the components of these batteries are sealed inside the battery box during use and will not affect the environment. However, after long-term mechanical wear and corrosion, heavy metals, acids and alkalis will leak out, enter the soil or water source, and enter the human food chain through various channels. This process is briefly described as follows: pond soil microorganisms, animals, circulating dust, crops, food and human nerve deposition. Experts believe that battery pollution has the characteristics of long cycle and great concealment, and its potential harm is quite serious. Improper handling will also cause secondary pollution. According to Dr. Yang Yifu, some farmers in a coastal province of China dumped waste liquid containing lead and sulfuric acid when recovering lead from lead-acid batteries, which not only caused lead poisoning, but also prevented local crops from growing. A grain of button cell can pollute 600 tons of water, which is equivalent to a person's drinking water for a lifetime. A grain of button cell can pollute 600,000 liters of water, which is equivalent to a person's lifetime drinking water. A piece of rotten battery in the field can make one square meter of land lose its use value, so it is no exaggeration to say that waste batteries are "small pollution bombs" Dry batteries commonly used in our daily life mainly include acidic zinc-manganese batteries and alkaline zinc-manganese batteries, both of which contain various metal substances such as mercury, manganese, cadmium, lead and zinc. After the discarded battery is abandoned, the shell of the battery will slowly corrode, and the heavy metal substances in it will gradually penetrate into the water and soil, causing pollution. The biggest feature of heavy metal pollution is that it cannot be degraded in nature and can only be eliminated by purification. The harm of waste batteries is mainly concentrated in the small amount of heavy metals contained in them, which shows the harm of metal types. Excessive manganese accumulates in the body, causing neurological dysfunction, which manifests as comprehensive dysfunction in the early stage. The heavier ones have heavy legs, monotonous language, dull expression and indifference, often accompanied by mental symptoms. Zinc and zinc salts can precipitate protein and have * * * effect on membrane mucosa. When the concentration in water exceeds 10-50 ms/L, it is carcinogenic and may cause chemical pneumonia. Lead: Lead mainly acts on nervous system, blood circulation system, digestive system, liver, kidney and other organs, which can inhibit the anabolic process of hemoglobin, and can also directly act on mature red blood cells, which has a great impact on infants and young children, leading to physical retardation of children, and chronic lead poisoning can lead to mental retardation of children. Nickel powder is soluble in blood, participates in internal circulation, and has strong toxicity, which can damage the central nervous system, cause vascular variation, and even lead to cancer in severe cases. Mercury is the most noteworthy of these heavy metal pollutants. This heavy metal is very harmful to human beings. For a long time, when producing dry batteries in China, a toxic substance-mercury or mercury compounds has to be added. In China, the mercury content of alkaline dry batteries reaches 1-5%, and that of neutral dry batteries is 0.025%. Mercury used in the production of dry batteries in China has obvious neurotoxicity every year. In addition, it also has adverse effects on endocrine system and immune system. 1953, the Minamata disease that shocked the world occurred in Kyushu Island, Japan, which sounded the alarm of mercury pollution to mankind. Heavy metal pollution threatens human health. If people ignore the treatment of heavy metal pollution, they will eventually swallow the bitter fruit of self-brewing. Therefore, it is more and more important to strengthen the recycling of used batteries.
Question 10: What should I do to replace the used batteries of mobile phones? Don't throw away old batteries casually. Collected, there are special recycling of old household appliances and the like, which can be given to others.
I cleaned up the garbage a few years ago and accidentally put the battery into the fire and exploded. . . Scared me, I'll never throw it around again.
