[China Aluminum] Net: “There is no rubbish in the world, only misplaced treasures.†Excavating the surplus value of electronic waste, and truly making the best use of it, is not only an advanced environmental protection concept, but also a way worth advocating.
More recently, I would like to concentrate on the disposal of a batch of spent batteries and found that the community did not even classify the trash. This is not uncommon in the satellite city of New Delhi where I live. On the streets of India, the dumping of rubbish is commonplace, providing a lot of small animals with the convenience of feeding.
The battery contains polychlorinated biphenyls and is a carcinogen. A survey of soil samples from seven cities in India, such as New Delhi, Mumbai, Chennai, and Bangalore, showed that the average concentration of PCBs in industrial soils in India was twice the global level, and a large number of PCBs were commonly found in City and surrounding areas. Due to the large amount of e-waste generated, India's soil has been contaminated with organic materials such as heavy metals and PCBs for decades. The absence of supporting garbage collection projects has created conditions for continued pollution.
Not only India, but also many developing countries are experiencing e-waste pollution. According to statistics, the number of discarded electronic products in East Asia and Southeast Asia increased by 63% between 2010 and 2015, and the total amount of e-waste and per capita output both increased rapidly, and the speed exceeded the population growth. In 2007, if Apple launched a smartphone based on its predecessor, it has so far sold 7 billion smart phones globally, including non-smart phones. In 10 years, the total mobile phone production reached 17 billion, of which more than half have been Abandoned. It is no wonder that some scholars have expressed emotion: "For many countries lacking an environmentally friendly e-waste management infrastructure, the sudden increase in the amount of such waste is worrying."
Although the reduction of e-waste has become a consensus, how to correctly Handle it is to say it well and to do less. Because the proceeds from the sale to the recycler were small and inconvenient, some people chose to throw it away. As everyone knows, a No. 1 battery can contaminate one square meter of land; a button cell can contaminate 600,000 liters of water; the mercury content of an energy-saving lamp infiltrates into the groundwater layer and will generate hundreds of tons of wastewater. With the increasing burden of electronic waste collection and processing, how to reduce the pressure on environmental governance has become a practical issue that countries have to face.
In fact, the manufacturing of polluting e-waste is also changing waste into treasure. The key lies in changing awareness and handling methods. The e-waste itself comes with many useful and expensive materials. In a complex electronic component, there are more than 60 chemical elements. If you properly handle it, you can't find the "mother's house." The German second-hand electronics market is relatively mature. With convenient services, old electronic products are no longer "useless old bones"; France is enacting a nationwide e-waste recycling law to make manufacturers bear the main responsibility for recycling e-waste; In Japan, not long ago, the Tokyo Olympic Organizing Committee called on the people to donate as much as possible waste electronic products in order to recycle metal and produce all medals for the 2020 Olympic Games. There is a famous saying in the recycling industry that “there is no rubbish in the world, only the misplaced treasuresâ€, and the exploration of the surplus value of e-waste to make the best use of it is not only an advanced concept of environmental protection, but also a lifestyle that is worth advocating.
We are living in a rapidly changing technology era, and the speed of electronic product updates will continue to accelerate. Surveys show that even in Europe, where environmental protection is very important, only one-third of e-waste is currently recycled, and most of the remaining e-waste of mobile phones, computers, and television are illegally traded and thrown away. “Regular mismanagement has occurred in every country, and thefts and illegal recycling are commonplace.†“Consumers don’t know where to look for a recycling centerâ€... There are many things that can be done to eliminate the shortcomings of electronic waste as soon as possible. No matter which method is adopted, solving the next kilometer of e-waste "landing", today's garbage can become tomorrow's resources.
