There are many reasons why it is important to recycle electronic waste. Much of the material used to construct electronics，including metal and plastic parts，can be recycled into new items at a discount of the cost and energy use needed to create things from new raw materials（原材料）. Additionally，many electronics contain poisonous substances （有毒物质）that are harmful to the environment and could be deadly if they go into an  area's groundwater. When properly recycled，they can be reused and will not do harm to the environment. Because of these environmental concerns，many areas require by law that electronic waste be properly recycled.
