Those bins in M+S and tesco are just for PR. They don't do anything different with the cards than with leftover till receipts ie into the recycling bin, where they are pulped or used for fuel. Maybe they fish out the ones with glitter or plastic bits first and put those in general waste.
There used to be charities that took old cards and remade them, either by cutting off the pretty part and sticking it onto card, or by sticking a new surface onto the inside. I still have a stash waiting to find somewhere that will do this again. I suspect there may have been problems with copyright, but it would be possible to save the credit as part of the repurposing. With all the upcycling going on now I'm surprised there's not a whole industry doing it. Think of those really nice cards with great illustrations, being seen for five minutes then binned is such a waste.
Anybody?
