Now I've learned that CDs and DVDs can be recycled, which is a good thing since they're made of chemicals and metals that have no business being in a landfill, e.g. "aluminum, gold, silver and nickel with petroleum-derived plastics, lacquers and dyes."
To learn how to recycle your CDs and DVDs, visit Earth 911. You might also consider using the GreenDisk Technotrash Can service. The company will handle up to 20 pounds for about $7.
I haven't given up on my CD project just yet, but its good to know that I'll have something to do with my box of CD-R coasters in case I do.
