In the past, we have seen people riding bicycles in the countryside, walking the streets and alleys to recycle old mobile phones, using pots or kitchen knives to change mobile phones, etc. What are these old mobile phones used for after recycling? What's behind it?
With the development of the economy, our living standards continue to improve, the use of mobile phone replacement speed is also accelerating, the market for recycling second-hand mobile phones is also getting bigger and bigger, data statistics, from 2015 to 2019, China's second-hand mobile phone recycling from 56.3 million to 85.7 million, the whereabouts of these mobile phones have also triggered a lot of people's speculations, so what is the secret behind the recycling of old hands?
Usually, people engaged in the business of recycling mobile phones include offline small traders and professional recycling agencies, but no matter what kind of recycled mobile phones, recycled mobile phones need to be detected, priced, and sorted for the next step. Generally speaking, mobile phones that do not have obvious traces of use, no obvious damage to the appearance and good functions can be sold directly to consumers after simple refurbishment, or bought in backward regions such as Africa and Southeast Asia. Most of the unusable mobile phones will be disassembled, and the heavy metals such as gold, silver and copper on the circuit board of the mobile phone will be extracted and reused, and the data shows that the gold content contained in a mobile phone is 0.015%, the silver content is 0.3%, and the copper content is 20%-25%. According to this ratio, if China's annual discarded mobile phones reach 400 million, the total weight can reach 10,000 tons, and all these heavy metals can be extracted in return of 300 billion yuan.
Of course, the extraction of heavy metals such as gold, silver and copper from mobile phones is not something that ordinary people can do, and needs to be handed over to a special person to operate, and there is another common method of processing, professional dismantling personnel can dismantle parts such as earpieces, speakers, cameras, etc., sell second-hand electronic components, and the cottage mobile phone assembly factory can be assembled into a new cottage machine with other components, which is also a processing method.
However, the Ministry of Industry and Information Technology predicts that after the popularization of 5G, China's annual waste mobile phones may increase from the previous 400 million to 520 million, and the entire second-hand mobile phone recycling market may exceed 300 billion. However, compared with Europe, the United States, Japan and other countries, China's mobile phone recycling rate is only 10%, why does this situation occur? Many people say that they would rather leave their phones idle at home for reasons such as low recycling prices and the possibility of information leaking. In fact, there is no need to worry about information, format the phone, restore to factory settings, there is no need to worry about the problem of information leakage. For people who are engaged in the profession of recycling mobile phones, it may take a lot of time and effort to find some private information from these mobile phones, and it may eventually outweigh the losses, and few people will move such evil thoughts.
