A DVD is very similar to a CD, but has a much larger data capacity, holding about seven times more data than a CD. This is why DVDs are used for the memory-intensive picture movies, while CDs are used for music. Both use the same technology.
Because CDs and DVDs are durable, convenient, easy to carry and store, and cheap to produce, they are now being widely used and are replacing other types of data storage. It is likely in the future we will have more and more of these plastic discs, rather than fewer. And each one will sooner or later be disposed of.
Reduce.
If you are using CDs for data storage, look into using DVDs instead -- you can store more data while using less material, thereby reducing the number of discs needed. If you use CDs and DVDs primarily for music and movies, rent them or purchase used CDs and DVDs. Each time the discs are reused, it reduces the number of discs that need to be manufactured and disposed of.
Reuse.
In addition to the obvious reburning of re-writable CDs and DVDs, you can reuse CDs and DVDs for a variety of craft projects. They are very easy to cut into any shape with ordinary household scissors and can be decorated with a variety of markers and paints.
Here are some simple ideas:
Drink coasters -- Buy a small piece of corkboard from a craft store,
Cut four 1 x 1 inch squares and glue them to the printed side of the CD. Leave the shiny side up as your coaster.
You can also use the pre-gummed felt circle table protectors instead of the cork.
Bird chasers -- Hang CDs in your garden. The shiny surface moving in the breeze will scare away birds. This works very well by orchardists.
Reflectors -- Use as reflectors on fenceposts, bicycles, driveways, or anywhere you want to call attention to something in the dark.
Garden Row Markers -- Write the name of the vegetable with a permanent marker on the CD-ROM.
Cut the edges of each into a flower shape if you want. Glue or tack the CD-ROM to a stick and put in the ground to mark your garden rows.
If the CD or DVD is music or a movie and you just don’t want it any more, put it back into circulation by trading them in at a music store that accepts used CDs, or donate them to charity.
Recycle.
CDs, DVDs, and their jewel cases can and are being recycled.
While they are generally not recyclable through local drop-off or curbside programs, there are a few well-established programs that separate and retrieve the various materials and recycle them.
Cases and CD's are pelletized, then end up as egg cartons and automotive parts.
If you are concerned about proprietary data on the discs, you can cut them with a ordinary household scissors, or place them one at a time in a microwave oven with a small glass of water for 5 seconds on the "high" setting.
