EPEAT, a certification organization that evaluates the recyclability of electronic devices, has tested a series of ultrathin notebooks from Apple, Lenovo, Samsung, and Toshiba and found that they meet the group’s environmental testing criteria, reports “InformationWeek” (http://macte.ch/K43Up).

The products investigated were “the lightest and thinnest of the manufacturers’ products,” a spokeswoman for the organization said in an email, confirming that the devices met EPEAT’s disassembly standards. This appears to include both the MacBook Air and Apple’s MacBook Pro with Retina display model, though EPEAT’s spokeswoman would not confirm this, says “InformationWeek.”

“We can’t name the products tested unless the manufacturers do so,” she said.
