The "Post a Phone" from designer Priestman Goode is made to be mailed in a standard flat-pack A5 envelope, along with an ample spool of telephone cord. It's a cunning design, but what struck me most was his choice of materials: recycled cardboard and plastic. Now I imagine the phone itself is made of plastic, but why? Since the Post a Phone concept implicitly acknowledges the disposable nature of an occasional necessity, could it be possible to put the electronics in a more recyclable housing?
I'm just thinking out loud here. It very well may be more expensive from cradle-to-grave* to make cardboard a reasonable substitute for a single piece of plastic. It just seems like these are the sort of products where paper and cardboard would be great solutions.
* Or "cradle-to-cradle," as the case may be.
