The eggshells we get left with are great for compost, but it would be even better to keep them out of the waste stream completely. You can easily turn them into sidewalk chalk – useful with the weather warming for kids to make art, games or write words of encouragement for the neighborhood.

I’ve been trying to make the most of the food I have under lockdown. After peeling some oranges and knowing I wasn’t allowed to compost the rinds, I wondered if there was a way to make the rinds edible – and quickly learned I could easily make tart candy citrus peels with just sugar and water.
