I've never come across anywhere that can recycle CDs, I didn't think they were recyclable.
Other uses I've seen
Hang them in the garden to scare birds.
Use them as coffee mats
Broken up (either put in a cloth and hit with a hammer or cut with string scissors) they make pretty mirror mosaic tiles.
A friend of mine has made some pretty mobiles by cutting CDs into strips, then heating them and twisting. I wouldn't want to do this indoors due to the fumes and also some CDs burn rather than melt.
