Managing Electronic Waste: Issues with Exporting E-Waste. CRS Report for Congress

摘要

Electronic waste (e-waste) is a term that is used loosely to refer to obsolete, broken, or irreparable electronic devices like televisions, computer central processing units (CPUs), computer monitors (flat screen and cathode ray tubes), laptops, printers, scanners, and associated wiring. E-waste has become a concern in the United States due to the high volumes in which it is generated, the hazardous constituents it often contains (such as lead, mercury, and chromium), and the lack of regulations applicable to its disposal or recycling. Under most circumstances, e-waste can legally be disposed of in a municipal solid waste landfill or recycled with few environmental regulatory requirements. Concerns about e-waste landfill disposal have led federal and state environmental agencies to encourage recycling. To date, 19 states have implemented some form of mandatory e-waste recycling program. These state requirements, mixed with increased consumer awareness regarding potential problems with landfilling e-waste, have led to an increase in recycling. With that increase have come new questions about e-waste management. Instead of questions only about the potential impacts associated with e-waste disposal, questions have arisen regarding the potential danger associated with e-waste recycling particularly when recycling involves the export of e-waste to developing countries where there are few requirements to protect workers or the environment. Answering questions about both e-waste disposal and recycling involves a host of challenges. For example, little information is available to allow a complete assessment of how e-waste ultimately managed. General estimates have been made about the management of cathode ray tubes (CRTs, the only devices where disposal is federally regulated), but little reliable information is available regarding other categories of e-waste. For example, accurate data regarding how much is generated, how it is managed (through disposal or recycling), and where it is processed (either domestically or abroad) are largely unknown. Further, little information is available regarding the total amount of functioning electronics exported to developing countries for legitimate reuse.
