In the face of 20 to 30 days of cell phone updates, 18 months of computer upgrades, as well as the proliferation of LCD monitors, rear-projection TVs, are you ready to or have you updated your consumer electronics? At this time, have you thought about what to do with the old products you have eliminated? Now more and more discarded electronic products become garbage, unknowingly affecting our lives.
For what is e-waste, although there is no clear technical standards to determine, but generally speaking, has been abandoned or can no longer use the electronic products are e-waste. For example: end-of-life television sets, out of the old computer, old refrigerators, microwave ovens, discarded cell phones and so on. When the number of these e-waste is more and more, its harm will appear.
E-waste is diverse and complex, and contains many toxic materials. The picture tubes of the televisions we watch every day contain explosive waste and a lot of heavy metal elements. A near-end-of-life 21-inch color TV, its tube has about 1 kg of lead, most of which is contained in the production of the tube in the glass material, so the overuse of the TV in addition to the image quality is not good, increase power consumption, like a "hidden in the home of the killer", at any time to disseminate the possible harm to human beings. The first step is to make sure that you have the right equipment for the right job.
Outdated or end-of-life computers are even more harmful than televisions. It takes more than 700 chemicals to make a PC, more than half of which are harmful to the human body, and when these chemicals are not recycled properly, the pollution to the environment is even greater.
In our country, due to economic development, a large part of the old electronic products that people have eliminated are still of great value for use in other areas. These can still be used in the old electrical appliances, old computers through the old goods trading market into the rural areas or economically underdeveloped areas, most of the other can not be used into the illegal dismantling of small workshops. But this is not the final destination for e-waste. Waste computers, televisions and other electronic waste after simple crushing, grinding and other processes, put into a strong acid solution dissolved, copper, silver, tin and other precious metals will be extracted, those "treated" waste has no use, it is discharged into the natural world, resulting in air, soil and groundwater sources of serious pollution, damage to the environment is simply the The damage done to the environment is simply shocking.
In the past, household appliances and electronic products have become e-waste, how to deal with these e-waste? Where is their better "home"? In foreign countries, has established a corresponding electronic waste recycling system and laws. Enterprises in the production of products at the same time to assume responsibility for the recovery of electronic waste, and electronic waste dismantling has formed a very professional division of labor. The recycling rate of electronic waste in the United States is more than 90%. Finland's electronic waste treatment plant, can realize the complete environmental protection recycling, will not cause pollution to the environment. The practices of these developed countries are worthy of our thinking and reference.
