　　Nowadays many people are concerned about the problem of what to do with electronic waste such as old televisions，computers，radios，cellular telephones and other electronic equipment.

　　Electronic trash，or e­waste，is piling up faster than ever in American homes and businesses.People do not know what to do with old televisions or computers so they throw them in the trash.

　　National Solid Waste Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected.

　　The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year，and there is a push by more states to ban the waste from landfills(垃圾填埋场) and create recycling programs.They can be torn apart and sorted for useable parts.Mike Fannon who runs the plant in Baltimore says，“There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill，and in certain components there are some materials that should not really be in the landfill.”
