The Environmental Protection Agency says Americans dispose of 130 million mobile devices annually; of that, only 8 percent gets recycled.
The turnover in phones continues to increase as new early-upgrade plans allow consumers to change models even more frequently. In 2014 Americans bought an estimated 152 million smartphones, according to estimates by the Consumers Electronics Association.
All that potential waste adds up. For every million cellphones recycled, 35,274 pounds of copper, 772 pounds of silver, 75 pounds of gold and 33 pounds of palladium can be recovered. Phones contain toxic chemicals that, when placed in a landfill, may ultimately go into groundwater and poison the water in surrounding areas. Most Americans say they know that recycling is important, but statistics show they don't always act accordingly, an EPA spokesperson explained to CBS News.
