Don’t Toss Those Eggshells: 17 Ways to Reuse Them

Getting rid of things like an eggshell is tough because they’re not great for garbage disposal and they leave behind odor and goo in our trash cans, sinks, and floors. Here are 17 things to do with them instead.

1. Put Eggshells in the garden

Interestingly, eggshells are rich in nutrients so they make a great fertilizer for the garden. Particularly, they’re high in calcium which will help create healthy plants and nutritious foods. 

2. Mix Eggshell with Coffee

For an extra dose of nutrition in the garden, mix the eggshell with a few scoops of ground coffee. It’s noted that specialty coffee should be avoided, but regular coffee boosts the eggshell’s nutritional power. 

3. Compost Eggshells 

Composting is a great way to reuse scraps from the kitchen, minimizing waste. While things like orange peels shouldn’t be added to compost, things like an eggshell are great additions to create a thriving compost pile. 

“It helps power the pile and adds more nutrients to it,” explains Jim, a garden expert. “It’s always a shame when I see somebody throw any eggshell away.”

It’s an instant fertilizer, it’s unbelievable how it works,” he added. “Simple nutritional things like that that are organic can provide so much power.”

Moreover, you can freeze them until you’re ready to compost them or make an “eggshell tea” by soaking them in water and using the tea for the garden. 

4. Use Eggshell as a Pesticide Alternative 

Crushing an eggshell into the garden won’t only boost crop health. It also acts as a pesticide because things like plant-eating slugs can’t glide over them the way they do the dirt, preventing them from causing damage. 

5. Mellow Out Coffee

Purportedly, you can add a few crushed pieces to your ground coffee to help mellow out the flavor. Furthermore, this will give you a little boost of collagen as well because store-bought supplements are often derived from eggshells. 

6. Use them to Scrub

The coarse texture of eggshells makes them ideal for cleaning pots and pans. Just crush a few and add them to a little dish soap. Next, scrub pots and pans with a sponge. 

7. Eggshells can Remove Stains

Putting crushed eggshells into a stained coffee or tea mug with some water and soaking it overnight can help remove some of those tough stains that stick around on mugs, seemingly forever. 

8. Use Eggshells for crafts

You can dye them, use them to make chalk or create beautiful and intricate mosaics. 

9. Turn them into Seedling Pods

Half an eggshell is the perfect size and shape to plant seeds in, plus they’re packed full of nutrients to help seedlings grow into healthy and thriving plants. Just add some dirt and the seed and bury it in the garden or a planter box. You’ll be amazed at how easy and cost-effective this gardening method is.
