SAN FRANCISCO, CA — A new effort to grade computer, television, printer and game console companies on their efforts to take back and recycle their old products finds most firms struggling to succeed -- news that comes to no surprise for anyone following progress on e-waste in the United States.

In the rankings, created by the Electronics Takeback Coalition, Dell and Asus score the highest, with B and B- grades, respectively. Samsung also earned a B grade, but was simultaneously dinged with a "dishonorable mention" by the group. According to its report card:

Samsung has made tremendous strides with its takeback program over the last two years and has earned a B on this year's report card. However, this report must also include a Dishonorable Mention because of serious concerns about Samsung's occupational health record at manufacturing plants in Korea, where many young workers have been diagnosed with blood cancers and several have already died.

Overall, the highest grades were earned by computer companies -- Dell, Asus, and Apple -- while the lowest grades were earned by printer manufacturers. Hewlett-Packard was the company with the highest grade in the Printers category, with a C-, while all the rest of the companies graded in that sector -- Brother, Epson, Lexmark, Kodak and Canon -- all earned Fs.

"If you don't offer physical collection sites or events, you are not serious about your takeback program," Barbara Kyle, National Coordinator of the Electronics TakeBack Coalition, said in a statement. "With so many cheap consumer printers being practically disposable these days, the printer companies should be doing a lot more to make sure they get their old equipment back. Most of the printer companies simply offer mailback recycling programs, but statistics show that people won't mail back larger products like printers."
