Computing power of used mobile phones

1. Apple mobile phone can resell computing power, and this system supports it

2. How to deal with old mobile phones? Is it random? Or is it recycled by the manufacturer? Or centralized management by government departments? These issues have been put on the agenda<

experts: actively promote

according to statistics, by the end of September last year, the number of mobile phone users in China had reached 250 million. If calculated according to the three-year turnover rate, nearly 70 million mobile phones are retired every year in China, generating 400000 tons of electronic waste

he Guili, director of China Tel laboratory, said that a small mobile phone uses more than ten metals with high recovery value, such as copper, gold, silver and palladium, as well as toxic and harmful substances such as lead, mercury, cadmium, hexavalent chromium, antimony, beryllium, nickel, zinc and polybrominated diphenyl ether. If the waste mobile phones are treated as ordinary garbage or burned, it will pollute the soil, water and air, and may cause diseases of human nervous system and immune system

therefore, professor he solemnly proposed that we should actively promote the safe disposal of used mobile phones. Professor Nie Yongfeng of Tsinghua University also put forward the same point of view. At the same time, he also said that it is technically feasible to recycle used mobile phones for treatment. Metal elements in mobile phones exist in solid form. After recycling, they can be disassembled by methods such as chemical decomposition. These technologies have made great progress in research at home and abroad

as for the main body of mobile phone recycling, the two professors pointed out that businesses are the most important. Professor Nie said that used mobile phones have high recycling value. For example, gold, platinum and other precious metals can save a lot of costs if they are recycled

businesses: in action

last year, Nokia, Haier, Hisense, Shouxin, TCL, Motorola, Samsung and other mobile phone manufacturers launched initiatives to improve the renewable utilization of procts and graally rece and eliminate the use of harmful substances. Take the initiative to take responsibility for the recycling of discarded mobile phones and accessories. At present, these mobile phone businesses are actively studying, formulating and implementing these action plans

Ms. Li, from the public relations department of Motorola in Beijing, said that since Motorola and other mobile phone manufacturers launched their first initiative last year, they have worked out a plan for recycling used mobile phones. At present, they are cooperating with technology research institutions at home and abroad to discuss the safe disposal of used mobile phones. Ms. Li promised that in front of the mobile phone sales counter in Beijing, Motorola's recycling cartons will appear in the near future to specially recycle the company's used mobile phones

it is understood that Shouxin is one of the leading domestic mobile phone manufacturers in this field. Last year, he Yaoliang, vice president of Shouxin, signed the "mobile phone environmental protection action" initiative on behalf of domestic mobile phone manufacturers, and solemnly promised to "proce safer, better quality and more environmentally friendly mobile phones, and recycle old mobile phones through the graal implementation of the old for new business"<

government: steady implementation of

the harm of waste mobile phones to the environment has also attracted the attention of government departments. Led by the State Environmental Protection Administration, it is cooperating with the National People's Congress in revising the law on the prevention and control of environmental pollution by solid wastes. One of the important contents is about the recycling of used mobile phones

an official from the material control department of the State Environmental Protection Administration said that there is no big technical difficulty in the treatment of used mobile phones in China. The main problem we are facing now is who will bear the cost of disposing of used mobile phones. It is impossible for the government to allocate funds for this work. The best thing is for manufacturers to pay for it. However, will manufacturers "share" the cost of disposing of used mobile phones and pass it on to consumers? This is a problem concerned and studied by the government, manufacturers and experts

in February 2003, the European Union issued and implemented the directive on waste electrical and electronic equipment and the directive on the prohibition of the use of certain hazardous substances in electrical and electronic equipment, which clearly stipulates that manufacturers of electronic procts, including mobile phones, have the responsibility and obligation to recycle procts that may have environmental hazards, The government has the responsibility to supervise this process

drawing on this experience, China is graally studying and formulating the "extended procer responsibility system", which advocates that "Whoever proces is responsible". Once it is implemented, China will have a rigid regulation on the recycling of used mobile phones, and the recycling of used mobile phones will have an effective solution.

If you don't need to sell an old mobile phone, you should not sell it. There is really no place to put it. You should also smash it and throw it away. Although it's not green enough, it's better than Wanyi's fraud

4. You'd better not sell the fake phones. I'll be sad to see the price
my mobile phone is still new. It's only sold more than 70, and your mobile phone is at most 60, so it's not worth selling

5. If you are worried that the old mobile phone will cause leakage, you can back up the important content in advance, and then delete it in turn, such as account password, address book, photo album, SMS, etc., and then restore the factory settings, so that the mobile phone will become the same as before without data. After these two steps are completed, a large amount of unimportant content can be stored in the mobile phone, so that the content can be covered and the deleted information in the mobile phone will not be recovered.

6. You can go to some mobile phone stores that specialize in purchasing old mobile phones

7.

Now everyone has at least one smart phone. With the progress of science and technology, the update speed of smart phones is faster and faster. Just bought a new one, maybe the next one has been developed

there are many smart phone brands, and various types of smart phones continue to add more life-friendly functions. Most people will pursue a new generation of mobile phones in order to seek the most face or novelty, and some people may change a mobile phone every year. In this way, each family will always have three or four mobile phones in idle state, so how do indivials deal with so many mobile phones

Where is the mobile phone

"I usually leave obsolete mobile phones at home?"

"newer mobile phones will give away, after all, they can still be used?"

"I won't sell it. It's not safe. I heard that someone will get personal information from an old mobile phone."

some people organize social surveys, for old mobile phones, users either leave them idle at home; Or give someone away; Or sell to second-hand mobile phone buyers. Among them, "put it at home" and "give it away" account for the largest proportion, up to 90%. Many people will not sell their mobile phones because it costs a lot of money to buy a new mobile phone. If they sell their old mobile phones to purchasers, they will not be worthless, and they do not believe that their personal information will be completely removed

on October 31, according to the Ministry of instry and information technology, by the end of September, the total number of mobile phone users in China had reached 1.316 billion. This means that in the future, hundreds of millions of mobile phones will be discarded in China every year, excluding those idle in previous years. According to the investigation. In China, only 1% of mobile phone users will recycle their mobile phones through regular channels. Many used mobile phones sold are sent to factories by second-hand mobile phone recyclers

so what's the use of the removed mobile phone

the recycled mobile phones are mainly used for three purposes:

1. Valuable popular models, such as apple and Xiaomi, will be renovated in Xiaowang's second and third tier cities. Of course, the price may be reced. Many people like to renovate their mobile phones because they want to be cheap

2. For some mobile phones with problems that cannot be renovated, they will be sent to the mobile phone repair shop for disassembly, and the available parts will be taken out for secondary use

Third, the mobile phones that are not reused will be sent to the factory for precious metal extraction. Under normal circumstances, it should be sent to more qualified processing enterprises. However, e to the lack of clear formal processing enterprises and the neglect of waste mobile phone recycling, many mobile phones are sent to small workshops to extract precious metals by burning and melting. It is bound to cause environmental pollution

mobile phones contain certain heavy metals such as lead, arsenic, cadmium, copper and zinc. The pollution intensity of a waste battery is 100 times that of an ordinary dry battery. If it is discarded at will, the heavy metals in the battery will enter into the soil and water, endangering the environment and human health. If burned, the plastic shell of the mobile phone will proce toxic substances, diffuse the air, cause air pollution and affect health. Moreover, it is not safe to leave the battery at home. After a long time, the battery will swell and decay, causing the solution in the battery to flow out. It is also a source of pollution in the family and endangers the health of the family

a mobile phone contains a variety of valuable materials, including gold, silver, copper and other precious metals. According to research, one ton of used mobile phones can extract 120 grams of gold, 3 kilograms of silver, 100 kilograms of copper and hundreds of kilograms of plastic. If discarded at will, hundreds of millions of used mobile phones in China every year will cause a waste of resources

it can be seen that used mobile phones are a rich mine. If the country recycles the used mobile phones every year, it can moderately alleviate the demand for precious metals in some instries

now, the biggest problem of mobile phone recycling in China is that there is no formal recycling enterprise. Moreover, compared with the cost of recycling and processing, the profit of mobile phone recycling is not high

in 2016, mobile phones have been included in the catalogue of disposal of waste electrical and electronic procts, but the specific rules have not yet been issued

First, the old mobile phone security processing method:

1. after the important data backup, restore the mobile phone to factory settings or format

2. access some unimportant content or large files (such as movies, useless pictures, etc.) for many times to fill the storage space of the mobile phone

3. install a "file shredder" to the mobile phone to erase completely, or go to the regular mobile phone recycling agency or maintenance center to ask professionals to completely destroy the mobile phone data

4. if the mobile phone has a memory card, try to put the privacy files in the memory card. When changing the mobile phone, just take out the memory card and insert it into the new mobile phone

5. don't throw your mobile phone away as household garbage

6. the safest way is not to store important private information in your mobile phone

9.

The update speed of current smart phones is too fast. Just bought a new version of mobile phone, maybe another one will come out in a few days. Xiaobian said that he couldn't afford it. So how to deal with the old mobile phone? Let's discuss it together

you can also go to the regular website or mobile phone store for processing, and there are special recycling agencies, but remember to delete all the personal information of the mobile phone, so as not to be embezzled by criminals

second hand mobile phones refer to the mobile phones that are eliminated when users update. They usually have some functional problems or aging, but not completely broken. As more and more used mobile phones are idle at home, they want to get rid of them

please think twice, maybe you are throwing away a small gold mine. There are gold, silver, copper, iridium and other precious metals in mobile phone parts. With the soaring global metal prices, recycling precious metals from second-hand mobile phones and other electronic procts has become a booming new instry in Asia - "recycling mobile phone instry"

mobile phone components. We know that today's mobile phones are made up of a lot of mobile phone components. Old mobile phones or broken mobile phones may only have the motherboard or a part of the mobile phone broken, resulting in the whole mobile phone can't be used, so these people will dismantle the components that can be used again on the mobile phone. On the one hand, when someone comes to repair the mobile phone, some replaceable components can be replaced directly, which can charge a high fee for the maintenance of the mobile phone. We know that the maintenance of the mobile phone is still a few hundred yuan, but the components of these old mobile phones are indeed exchanged at a low price

Another reason is the data stored in old mobile phones. A lot of people will delete the information in their mobile phones when they switch to their mobile phones, so many people think that the formatted mobile phones have no data to use. In fact, it is not. The formatted files can be recovered again with certain technical support. However, in this case, the formatted files can be recovered again, The data in the mobile phone will be used by some lawless elements. These data, whether they are sold or used by themselves, will have a great impact on us
