Researchers at the Rochester Institute of Technology and Peru’s Pontificia Universidad Catlica published a study in the October edition of the Resources, Conservation and Recycling journal finding that 40 million used computers in the United States were recycled, reused, or sent to landfills in 2010. The study, “Materials Flow Analysis of E-waste,” concluded that 30 percent were reused, 20 to 47 percent were recycled, and 17 to 21 percent were sent to landfills; between 6 and 29 percent were exported for end-of-life management.
