CD/DVD jewel cases are made of non-biodegradable materials; they will not decompose in a landfill, and destruction by burning is toxic. If your community has a Take It Back program, such as the one in Ottawa, you can find companies that specialize in recycling the cases. There are also companies online that will recycle these although you may have to spend a bit of money to ship the packages.

If you’d rather try your hand at reusing your empty jewel cases, there are a number of creative ways to repurpose them. You can easily transform a jewel case into a stand-up photo frame or a refillable desk calendar stand. If you have loads of empty jewel cases, you can pop in your favourite photos (cut to 4 3/4 x 4/ 3/4 inch or 12cm x 12cm) to create a wall display of your favourite pictures.
