Electronic waste, commonly known as e-waste, refers to waste electrical and electronic products. The term "e-waste" refers to electrical or electronic equipment that is discarded and no longer in use. E-waste needs to be handled carefully because it can cause serious environmental pollution and jeopardize human health.
There are many types of e-waste, which can be broadly categorized into two types:
One type is used electronic products that contain relatively simple materials and are less harmful to the environment, such as refrigerators, washing machines, air-conditioning units and other household appliances, as well as medical and scientific research electrical appliances, etc., and it is relatively easy to dismantle and dispose of such products.
The other category is the material contained in the more complex, more harmful to the environment of waste electronic products, such as computers, television tubes within the lead, computer components containing arsenic, mercury and other harmful substances, cell phone raw materials in the arsenic, cadmium, lead, and a variety of other persistent degradation and bioaccumulation of toxic substances.
