I don't know how exactly how many IT magazines are sold each month, but lot of cover discs must get binned, so why not make part of it recyclable? My preferred publications use the same kind of packaging, so there is obviously a very welcome movement in that direction.
I hope that is so. My latest issue October came in the case. The cases I find most useful . The older discs from 1 year back get transferred into clear plastic envelopes with the main content slip and the cases recycled for my masterpieces.
