The incredible, edible egg, indeed—even the shells serve up extra usefulness! Put your breakfast remnants to work in the kitchen, garden, and even the first aid kit with one of these five hacks.

Delicious and versatile, eggs are on the ingredients list for countless favorite recipes. But while the yolks and the whites go into breakfasts, lunches, and dinners, the eggshells typically go nowhere but the garbage bin. All those wasted shards add up, apparently. According to, Americans trash about 150,000 tons of eggshells each and every year! Things would be different if everyone knew that you can actually use eggshells for a variety of tasks both in and around the house.


Uses for Eggshells - Seedlings


If you’re itching to start gardening indoors before spring officially arrives, remember that eggshells make an excellent vessel for seedlings.

Uses for Eggshells - Natural Bandage


The next time you nick a finger while slicing and dicing in the kitchen, rest assured there’s a natural bandage within easy reach.

Uses for Eggshells - Get Rid of Snails and Slugs


Gardens are gorgeous; unwanted snails and slugs are not.
