Abandoned mobile phones are seriously polluted and have high recycling value.

At present, mobile phones have almost become a necessary communication tool for human resources. However, with the acceleration of mobile phone replacement, the problem of recycling used mobile phones is also in front of people. A few days ago, some media pointed out that mobile phones and built-in lithium batteries are seriously polluted after being discarded, but they contain a variety of precious metals, which should be recycled after recycling.

According to data released by the Ministry of Industry and Information Technology, China’s mobile phone users have exceeded 1 billion, and the number of discarded mobile phones has reached 100 million each year. The United Nations recently released the "Electronic Waste for Resources" report predicts that by 2020, the number of discarded mobile phones in China will increase by seven times compared with 2007. But unfortunately, at present, China has not established an effective recycling system for discarded mobile phones, and the recycling rate of discarded mobile phones is less than 1%. More and more discarded mobile phones have put tremendous pressure on the environment.

It is understood that there are three main places for people to abandon their mobile phones: the first is to be at home, the second is to discard them casually, and the third is to sell to street vendors. Some insiders pointed out that if the discarded mobile phone is incinerated as garbage, the plastic shell of the mobile phone will produce chlorine-containing toxic substances and even produce primary carcinogens. The mobile phone lithium battery pollution amount is equivalent to 100 ordinary dry batteries. A traditional used mobile phone contains up to 20 substances that may be harmful to the environment. An old mobile phone battery can pollute 60,000 liters of water, equivalent to three standard swimming pools. In addition, some of the used mobile phone batteries are often recycled by some lawless elements and then made into counterfeit and shoddy batteries. The safety risks are enormous, which poses a serious threat to consumers' interests and personal safety.

But on the other hand, the abandoned mobile phones that have plagued many people contain a variety of precious metals and are a hidden "gold mine." According to media reports, a mobile phone contains 0.01% gold, 20%-25% copper, and 40%-50% renewable plastic. The total weight of 100 million discarded mobile phones is 10,000 tons. If it is recycled, it can extract 1,500 kilograms of gold, 1 million kilograms of copper and 30,000 kilograms of silver. This is a very exciting number.

However, some insiders pointed out that the recyclable value of a single mobile phone is not large. Therefore, it is more feasible to concentrate on recycling. In view of the fact that there is no unified recycling system in China at present, some experts suggest that the charger can be standardized first, which can greatly reduce the generation of mobile electronic waste.
