Hi. I would like to know if anyone has used old cd’s or dvd’s to make certain items. I have access to thousands of these and am looking for ways to recycle instead of sending to landfills. I also have the cases, which I believe are made from polypro.
The old “jewel CD case” design is polystyrene. See:
There have been a mixture of other types (although these are a minority).
Traditional DVD cases are said to be polypropylene (same link as above). However the outer transparent sleeve (holding the printed paper label) might be made from some other material. If so, it means that the DVD case is mixed palstic, and hence difficult to process.
