Cracked eggshells are messy. Residual egg white (albumen) clings to the inside of the shells, creating a sticky and smelly situation. Piling those shells back in the carton essentially turns it into a mini compost pile right in your fridge. The odor may not hit you immediately, but over time, it can seep into other foods. Suddenly, your fridge has a faint but unmistakable smell of rotten eggs—all because of a shortcut.
Egg Cartons Aren’t Built for That
Egg cartons are designed to protect clean, whole eggs. Most are made from cardboard or foam, which absorb moisture and trap odors. Once contaminated with sticky, used shells, the carton becomes unusable for recycling, repurposing, or safe storage. You’ve effectively ruined something meant to keep your food clean and safe.
The Right Way to Dispose of Eggshells
The better option? Keep a small bowl nearby when cracking eggs, and place the empty shells there. When you’re done cooking, you can toss the shells into the trash, compost bin, or even use them in your garden—crushed eggshells are great for soil. The key is keeping them out of the carton and out of your fridge. A simple habit change can protect your food, keep your kitchen cleaner, and reduce unwanted smells.
