Disposing of eggshells might seem like a hassle, but they actually have a wide range of eco-friendly and practical uses. In the garden, their high calcium content makes them an excellent natural fertilizer, and they can help deter pests like slugs. You can compost them, blend them with coffee grounds, or steep them in water to create a nutrient-rich “eggshell tea” for your plants.
Around the house, crushed eggshells are surprisingly versatile. They work well as a gentle abrasive for scrubbing pots, removing stains from mugs, or even cutting the bitterness in coffee. In DIY projects, they’re perfect for making mosaics, decorating vases, or creating biodegradable seedling starters. They can even be fed back to chickens, used to sharpen blades, or crafted into unique candle holders.
Eggshells also offer some health-related benefits. You can grind them into a calcium-rich paste for dental care, use them to draw out splinters, or apply them to soothe blisters. They’re also fun for science experiments—just soak one in vinegar to see the shell dissolve.
Instead of throwing eggshells away, consider reusing them to cut down on waste and bring added value to your home, garden, and everyday life.
