Waste electromechanical and waste household appliances, including scrapped cars, bicycles, electric vehicles and other vehicles, televisions, computers, mobile phones, DVDs, medical devices, floppy disks, and waste batteries, household appliances, rubber hoses, and other materials and chemicals that require metal and require energy. Energy system. The disposal and management of waste electromechanical and waste household appliances has become a common concern of all countries in the world. About 20 million tons of steel is used annually in China for the production of electromechanical and home appliances, plus auxiliary materials such as plastics and rubber products, with a total mass of 30 million tons/year. After a few years, these electromechanical and home appliances became waste. Waste electrical and mechanical appliances and waste household appliances are largely different from ordinary urban household waste.

Compared with waste electrical appliances, waste electrical and mechanical equipment also does not rot and produce percolating water and gas in a dry environment, but waste electrical appliances will find the above situation. E-waste is also different from industrial hazardous and toxic solid wastes with large quantities and low value. Waste electrical machinery and waste household appliances will cause serious pollution to the environment without proper treatment. If the waste is discarded at will, after the wind and rain, the harmful toxic substances in the electronic waste will be released, and the surface water will flow into the groundwater or invade the soil, causing certain pollution to the groundwater and soil. Therefore, when considering the technology and management of e-waste, practical measures should be formulated for the characteristics of e-waste.
