Eggshells can be recycled! Just rinse them out, let them dry for a a few days, crush them up and mix in with soil to add nutrients for your plants. I keep an empty ready-made frosting container on the sill above my kitchen sink to collect and dry eggshells, then mash them easily with a small metal meat mallot.
Another thing I occasionally recycle is banana peels, but they aren’t too appealing to photograph [snickering to myself at the play on words]. Roses LOVE banana peels. Just chop the peels into 1″ pieces and bury them a couple of inches in the soil.
Note from Amy: Two things I love about this: that my mom wrote “Egg Shells” in big green letters on the side of the frosting container, and that she actually takes the time to do this with all her egg shells. Mine come to their final resting place in le garbage. But then, you should see Mom’s garden.
