I never think twice about eggshells, once I crack an egg, I simply chuck the shells away. Little did I know that I can use eggs for way more than simple compost, the only thing you have to do is sanitize your egg shells. Drop the eggshells into boiling water, let them hang out for 15 minutes, lay them on a towel to dry completely, and then bake them in the oven for 20 minutes at 250 degrees F, this sterilizes the shells completely, removing any harmful bacteria. Depending on how you want to use the shells, you’ll want to remove the inner membrane (but not for things like softening your cuticles). You can then grind the cleaned eggshells into a powder and use the shells in large chunks. Follow these tips to make your food and food scraps work overtime for you.
