Eggshells: most of us crack an egg, toss the shell, and never think twice. But what if those humble shells you’re throwing away could actually make your daily life healthier, greener, and even a little easier? Americans are becoming more conscious about reducing waste and making the most of what’s in their kitchens. Discovering creative, practical uses for eggshells isn’t just good for the planet—it can also benefit your home, garden, and even your health in surprising ways. Read on to learn why you should stop throwing out eggshells and how to start using them today.
Why Eggshells Deserve a Second Chance
Eggshells are made almost entirely of calcium carbonate, a mineral that’s essential for strong bones, healthy plants, and more. They also contain trace minerals like magnesium and phosphorus. Instead of letting these nutrients go to waste, you can put eggshells to work in several safe and practical ways around your home. While research suggests eggshells can be beneficial in certain uses, it’s important to handle them properly and follow safe practices.
Eggshells in the Garden: Nature’s Free Fertilizer
If you love gardening, eggshells can be a game-changer. Here’s how:
1. Boost Soil Health
- Crushed eggshells add calcium to the soil, which helps prevent problems like blossom end rot in tomatoes and peppers.
- They also improve soil structure, making it easier for roots to grow.
2. Natural Pest Control
- Sprinkle crushed eggshells around the base of plants. The sharp edges can deter soft-bodied pests like slugs and snails.
3. Compost Enhancer
- Adding eggshells to your compost pile increases its calcium content, which helps balance the nutrients in your finished compost.
How to Use:
- Rinse eggshells thoroughly and let them dry.
- Crush them by hand or with a rolling pin.
- Sprinkle directly in the garden or mix into compost.
Quick Tip: Always rinse eggshells before use to reduce the risk of bacteria.
Eggshells for Household Cleaning and Freshening
Eggshells aren’t just for the garden—they’re also handy for cleaning:
1. Natural Scrubbing Powder
- Crushed eggshells are mildly abrasive, making them perfect for scrubbing stubborn pots, pans, and sinks.
- Mix with a little dish soap and use as a gentle cleaner for hard-to-clean surfaces.
2. Drain Cleaner
- Drop a few crushed eggshells into your kitchen sink strainer. They help trap food particles and, as they break down, can help prevent clogs.
3. Odor Neutralizer
- Place dried eggshells in the bottom of your trash bin or compost pail to help absorb odors.
How to Use:
- Dry the shells completely before crushing to avoid any lingering smell.
- Store crushed shells in a jar for easy access.
Eggshells for Health and Wellness (With Caution)
Some people use eggshells as a calcium supplement, but it’s important to be cautious. Research suggests that properly prepared eggshell powder can be a source of dietary calcium, which is important for bone health. However, consuming eggshells requires careful cleaning and sterilization to avoid foodborne illness. Always consult your doctor before adding eggshell powder to your diet.
How to Prepare Eggshell Powder:
- Rinse eggshells thoroughly and boil for at least 10 minutes to sterilize.
- Bake at 200°F for 10–15 minutes to dry.
- Grind into a fine powder using a clean coffee grinder.
- Store in an airtight container.
Important Note: Only use eggshell powder if your healthcare provider approves. Never consume raw or unsterilized eggshells.
Eggshells for Crafts and Creative Projects
Eggshells can spark creativity for adults and kids alike. Here are a few ideas:
1. DIY Chalk
- Mix eggshell powder with flour and water to create homemade chalk for sidewalk art.
2. Seed Starters
- Use half-shells as tiny pots for starting seeds. When it’s time to transplant, plant the whole shell—roots will grow right through.
3. Mosaic Art
- Dye and break eggshells into small pieces to make colorful mosaics for cards, frames, or other crafts.
How to Use:
- Rinse and dry shells before using in crafts.
- Let kids help with safe, supervised projects.
Eggshells for Pet Care and Bird Feeders
Eggshells can also benefit your pets and local wildlife:
1. Calcium for Backyard Chickens

2. Bird Feeders
