How to Dispose of a CD
CDs are a fantastic way to store large amounts of data and are so inexpensive that backing up computers or using them to store information is common. Unfortunately, unless the CD is a CD-RW, which is rewriteable, the data burned onto it is permanent. When you no longer need it, you must destroy the used CD if you don't want that information to get into the wrong hands.

Look for a paper shredder that also handles credit cards and CDs. These models are affordable and offer the quickest, cleanest way of disposing of a CD no longer needed. Slide it in and it's history. Most shredders with this feature shred 10 sheets of paper or more at a time.

Try breaking the CD into pieces, but only while wearing gloves and eye protection because edges of broken CDs are sharp and cut easily. Breaking a used CD in half or quarters is sufficient to destroy the information contained on it.

Use wired bristled brushes, similar to ones used on barbecue grills, and scrape the used CD until the plastic base is visible through the layers of data storage to destroy it.

Opt for rough grit sandpaper or use a belt sander to work off the surface of the used CD so it's no longer readable.

Place the CD on a paper towel or paper plate along with a cup of water and turn the microwave on for about 5 seconds. The microwave destroys any data on the CD rather quickly, while the towel or plate saves the bottom of the microwave from any melting damage.

Tips & Warnings
When you microwave a used CD to destroy it, the water helps to absorb the waves emitted. There are sparks and a burnt plastic smell, and allowing it to go too long or without the towel or water can cause serious damage to the microwave, destroying more than just the CD.
