5 Things to Do with… Eggshells

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.


If you're itching to start gardening indoors before spring officially arrives, remember that eggshells make an excellent vessel for seedlings. When your plants finally outgrow their temporary homes, you can transplant them, shells and oil, directly into the soil, because the shells biodegrade. Read all the details at Instructables.


The next time you nick a finger while slicing and dicing in the kitchen, rest assured there's a natural bandage within easy reach. It so happens that in a hardboiled egg, the membrane between the shell and the white can help stop the bleeding and serve as a makeshift Band-Aid until you can give your injury proper attention.


Believe it or not, you can make sidewalk chalk out of eggshells. First, grind the eggshells into powder. Next, mix the powder with tap water, flour, and food coloring (in your favorite bold hue), forming a batter-like paste. Finally, add the mixture to a silicone mold.

You already know that ice cubes sharpen the blades in your blender But did you know that eggshells do the same thing? Why not save the shells in your freezer, pulling them out whenever your blender needs a performance a boost? Just make sure to clean the blender afterwards, so you don't get any crunchy surprises.


Gardens are gorgeous; unwanted snails and slugs are not. To get rid of these slimy creatures without resorting to chemical pesticides, simply spread crushed eggshells in a circle around your plantings. Rather than crawl over the jagged edges of the shell flakes, the pests would rather crawl back to where they came from.
