Apple has withdrawn all of its Mac products from EPEAT certification and will no longer be submitting items for review, according to a recent announcement by the recycling rating service. EPEAT is used by hundreds of companies, universities and government agencies in dozens of countries as an index of electronics recyclability. Despite the withdrawal of all Macs, most models still meet EPEAT standards for recyle-ability -- but the move could foreshadow some changes in design on the horizon.
