So, these are not to be put in the recycling bin.

If there is no craft idea of interest or feasibility, or way to repurpose them from home, what is to be done with CD cases other than adding them to the landfill?

Any idea?  I am stumped.....

I would suggest put a bunch in a ribbon. Throw out the damaged ones. Offer them in the Random Acts of Kindness or give them to your Goodwill. A pack of 50 empty clear CD cases go for $28.00 on Amazon.

I've purchased DVD cases in bulk to replace damaged cases I have or have purchased at a yard sale. Maybe someone needs to replace their CD cases too.

Here are some interesting ideas.  https://www.diys.com/use-old-cd-cases/
