A recycler of cell phones, eRecyclingCorps (eRC), announced on February 26 that it had reached the 10 million cell phone trade-ins milestone since its inception in 2009. In addition, eRC almost tripled its year-over-year volume with over seven million cell phone trade-ins in 2012. According to the Environmental Protection Agency, U.S. households have over a billion unused cell phones and only 10 percent of cell phones are being recycled.
