Thank you so much for sharing your ideas re: old diskettes and used papers. Another question for this week is: As teachers we always throw away smaller pieces of chalk. Do you have any idea what to do with it to make it still useful?

Good for you for recycling things!
This article tells how to smash it, mix with water and reform to make bigger more usable pcs of chalk. You might also be able to put them in some kind of mold or recycle a yogurt cup or something to make more of a molded shape. If it is too chunky to use for blackboard use the kids can use it as sidewalk chalk and you can add a bit of tempura paint powder to color it if you want.
This tells how to make the chalk dust as above and turn it into sidewalk paint.
Here are some other uses for chalk. I have heard of using it for the laundry use before. Also have read you can put a few pieces of chalk in a toolbox to keep your tools from rusting.
Along the lines of using chalk to keep tools from rusting, if you want to help prevent tarnish on jewelry (or silverware), you can store it in a plastic bag with a piece of chalk. The chalk will absorb moisture. Don't do this with pearls or opals, the low moisture is bad for them.
White chalk is great for treating ring-around-the-collar and sweat stains on clothing. It absorbs the specific oil in those and makes it easier for your detergent and water to remove the stains.
