Now through August 30, 2013, Apple will recycle your school’s old, unwanted Mac computers, PCs, and qualifying peripherals from any manufacturer — at no cost. There’s no purchase required, and all accredited K-12 and higher education institutions with at least 25 recyclable items are eligible to participate.
To start, you’ll need to register. Then all products must be packaged according to Apple’s detailed packaging instructions. Last but not least, you must recycle a minimum of 25 items.
