Eggshells, often discarded after breakfast, are surprisingly useful for the home, garden, and health. Rich in calcium carbonate,

they make excellent natural fertilizer, especially for tomatoes, peppers, and eggplants. Crushed shells also deter pests

like slugs and snails without harming pets or the environment. In compost, they enrich soil nutrients—mix with coffee grounds

for a nutrient boost. You can also make “eggshell tea” by steeping crushed shells in boiling water overnight for a mineral-rich plant drink.

Around the home, crushed shells serve as a gentle abrasive cleaner for pots, pans, and mugs. Adding some to coffee

grounds reduces bitterness and acidity. Cleaned shells can be repurposed into candles, air fresheners, mosaics,

and kids’ craft projects. Halved shells work as biodegradable seed starters—just plant them directly in soil.

For health, boiled and finely ground shells can be used (safely and in moderation) as a calcium supplement, supporting bone health. Powdered shells

can also be mixed with baking soda and coconut oil for natural toothpaste. The inner membrane soothes skin, draws out splinters, and reduces inflammation.

Even as a science experiment—like dissolving in vinegar—eggshells teach chemistry. Reusing them reduces waste,

saves money, and turns a common kitchen scrap into a versatile resource.
