Can CDs Be Recycled?

An anonymous reader asks: "I was recently doing a closet-cleaning and came across literally hundreds of old software CDs that are no longer usable — both manufactured CDs and CD-Rs. Note that by 'not usable', I mean that many of them simply couldn't be read anymore, possibly due to the fact that they'd been stored rather ineptly (no, I wasn't responsible for how they were stored). It seems wrong to just throw them out, but are there other things that can be done with them that will allow their raw materials to be reused in some way?Is it possible to reclaim CDs for raw materials?"

It pains me everytime I have to throw away perfectly good alumim(i)um foil. As it is, trying to roll a ton of it into a big ball for recycling would only serve to make me (a) $.02 richer, and (b) a laughing-stock.

      OTOH, in Austria (or at least several parts of it) you are supposed to sort your garbage into separate trash cans for organic, plastic and metal parts. Therefore, if you buy sliced ham at the butcher's, the coated paper that it comes wrapped in can easily be taken apart for separate disposal. Very nice.

  20. Cheat or hoax, you can *not* write to normal CDs by Dogtanian · · Score: 2, Interesting

    How it worked or whether it was a hoax is anyone's guess. If this was real, then I'm going with what one other user suggested; it wrote updates to the hard disk (or some other reusable medium). I saw software like this for the Amiga. And although it's a useful idea in the context of its time, it's misleading to suggest that this is actually writing to the CD itself.

    If that wasn't the case, I'm pretty sure it's a hoax. Why? Because commercial CDs aren't like CD-R/RW; the latter have crystalline layers that respond to heating changes from the laser to form reflective/non-reflective areas, the former are actually *stamped* with 3D pits and lands.

    Both reflect/deflect the reading laser beam in the same way (in most players), so the discs can be read in the same machines. However, there's no way you're going to *change* the contents of a stamped CD in anything like the same manner as you would with a CD-R. It's about as likely as a floppy disk drive's magnetic head being able to rewrite the grooves of a 7" vinyl single.

    In fact, you'd actually have to (somehow) melt or reconfigure the plastic of the CD itself, and since it was never designed for this, I've no idea how you'd do it accurately. It would likely be a horrifically expensive (and pointless) lab curiosity at best, and no-one in their right mind would try to market it in the face of CD-R.
