There are not many formal and sound recycling institutions in China, and they are often small privately established recycling institutions. The key of electronic waste treatment is recycling, and it is difficult for small recycling institutions to complete a wide range of electronic equipment recycling tasks, so some discarded electronic equipment has become environmental pollution sources.
Establishing a perfect recycling system needs the support of the broad masses, and at least has the following two points: one is door-to-door recycling, and the other is telephone contact. Through these two items, the recycling problem of some electronic equipment can be well solved, and the trade-in policy implemented by the state is also a very good means. If this mechanism is normalized, it will certainly play a very good role.
E-waste is profitable
Waste electrical appliances can extract many valuable metals, such as gold, platinum and indium. Needless to say, gold and platinum, indium is called metallic vitamin, and its price has now risen from 70 dollars per kilogram to 1200 dollars. If the waste batteries in old mobile phones are recycled, the total amount is 1 ton, and 200 grams of gold can be extracted. You know, generally only 2 grams of gold can be extracted from each ton of gold-bearing ore.
The annual profit of American electronic waste disposal companies has reached $25 million to $30 million (according to statistics, it costs $300 to mine 1 ounce of gold and only $ kloc-0/ounce to recover 1 ounce of gold). Yongkang, known as the "Hardware Capital" of China, is the largest scrap metal recycling base in China, with more than 200 scrap metal processing and training companies. The annual turnover of scrap metal reaches 6-7 billion yuan, and the output of alloy aluminum is about 250,000 tons.
