10 Reasons To Stop Throwing Away Your Eggshells

Statistics say the average American consumes 250 eggs per year. Remember, we’re not just eating two at a time, sunny-side-up, we’re using them in our homemade baked goods, batters, main dishes, and more. And if you think the only two solutions for all those eggshells are the trash or composting pile, you may want to think again.

Reuse Them!

In the age of recycling, eggshells —nature’s suit of armor and an excellent source of calcium and minerals—can be reused in many ways that don’t readily come to mind. Enterprising consumers can make the best of what most would consider a highly disposable item.

Top 10 Uses for Eggshells

These ideas can help you raise your eggshell IQ. In all cases, except where specified, eggshells should be crushed, made either coarse or fine, depending on the use:

  1. Use eggshells as a calcium- and mineral-rich additive to wild bird feed and chicken feed.
  2. Add them to ground coffee before brewing. The shells help reduce any bitterness.
  3. As a soil additive for houseplants, they add minerals and help keep soil loose and aerated.
  4. Love camping? Use those shells with soapy water as a natural abrasive for pots and pans, especially when cleaning products and really hot water are at a premium.
  5. Bake clean eggshells at 350 degrees for 8 minutes. Let cool and grind to a fine powder. Add as a calcium supplement (a teaspoonful does it) to juice, smoothies, etc.
  6. Add to your garden to keep cats away that may be using it as a litter box. Cats will not like the sharpness under their tender paws. Their smell can also reportedly deter deer and repel slugs, snails, and cutworms without resorting to toxic chemicals. Maybe tantamount to that, mineral-charged eggshells can be crushed and scattered into each hole before planting. Sprinkle additional crushed shells around your plants every couple of weeks. Use them to start your seedlings! Here’s how.
  7. Skin irritations? Folklore tells us to drop an eggshell into some apple cider vinegar for a couple of days. Apply to skin irritations or itches.
  8. Unclog drains: Placed in your sink strainer, they can trap errant solids. When they ultimately break down, they will serve to clean pipes on their way out.
  9. Doggie defense: Dry eggshells in a 250-degree F oven for 30 minutes. Place in plastic bag and roll/crush with a rolling pin to a fine powder. Add to dog food as a supreme calcium supplement (be sure to check with your vet for the proper amount).
  10. Looking for a fun art project? Crush and add to paint for decorative textured walls or furniture!

I have used egg shells as planters for years. Also, (if you buy eggs in the clear plastic cartons) these make great mini green houses. You can adjust the lid to control temp and humidity. Just place a cotton ball in each corner and soak with water, mist the inside of the lid, if you are unable to water for a day or two. Keep lid closed, but not sealed. Once plants are large enough for the garden, carry them out, plant, start again! To identify plants, ( I know.. You’ll remember!) Use cuticle sticks ( broken in 2″ pieces. Dip ends in non toxic acrylic paint. Make a chart.. Blue: catnip. Red: sage.. Etc. Insert unpainted end in egg planter. If you are really organic, use beet juice, blueberries, cucumber.. Or any fruit or vegetable that stains. Happy gardening!

Thanks for so many ideas for using eggshells that will add to the ones I was taught by my elders. Used to think their ideas were “old wives tales” until I became an adult and used in my own planting and gardening efforts. Now, I have a few more new ideas to put into practice.

3 Viola Maxwell { 08.10.18 at 1:54 pm }

When you clean lint from dryer screen, place lint in empty egg carton boxes and when each section is filled pour melted wax (old candles are great) over lint. Break sections apart to start fire in your fireplace or barbecue grill.

4 Chris { 08.12.17 at 9:51 am }

With a pin make 2 tiny holes, one on each end of the shell. Then use the pin to break the yoke inside the eggshell. Either allow the egg to drip out or use a little force by blowing into one hole and cook egg as usual. Put eggshell in your chickens nest and this will promote her to lay more eggs.

Hi Kyle Powell: Yes, we have some great ideas for the non-plastic cartons, too! Check it out (and thanks for your idea!):

There are plenty of great ideas for eggshells here. But what about those cardboard containers the eggs come in? Try this and put a charcoal briquette in each little section of the container. Then drizzle melted parafin over each one. The finished product makes a nifty little package that’s neat, easy to store, and great for starting a charcoal grill while camping or boating. We used them on our sailboat when I was growing up and they worked like a charm!

The super success of first Knights of the Old Republic game initiated a sequel’The Sith Lords, which has all the key aspects of the first RPG plus more re-playable quests and a good storyline.

If you suffer with slugs and snails eating your Hosta plants scatter broken eggshells around the plants. That’ll keep them away !!

9 Steven { 03.01.16 at 5:02 am }

I was taught to float eggshells on top when making a stock. When cooled the fats stick to them and make skimming easier.

All GREAT IDEAS.. I am moving to a new home and can’t wait to start using all of the gardening tips!

15 Vickie O { 07.09.15 at 8:33 am }

Use then as containers to start seeds! When ready for transplant, crunch the bottom so roots can get out and bury the whole shell.

16 Laurie { 07.09.15 at 8:20 am }

Don’t forget to save the egg cartons. Useful for many small items: nails, pills, beads…

17 liam barrett { 07.09.15 at 3:50 am }

I use the boiled egg water as s patio weed killer. Just pour it on the weed and it will burn it away.

18 Martha Bredwell { 07.09.15 at 1:04 am }

You can also put the eggshells in a jar with some water, wait a week, then sprinkle the water on your plants for the minerals.

19 Ignatz { 07.08.15 at 10:59 pm }

This is an uncommon use, but if you keep snails in tanks, you can actually use an eggshell to patch a cracked snail’s shell.

20 lonnie { 09.04.14 at 5:34 pm }

grind them up and put them in your chicken feed

I like putting them into my compost for the worms to eat grind them fined for them

27 Deborah { 08.21.14 at 10:29 pm }

Break up the shells into small pieces and glue down on a substrate to make a mosaic picture. Paint shells before or after. Sign and frame for an original work of art.

28 Deborah { 08.21.14 at 10:26 pm }

Don’t give to dogs under 1 year old as they can cause problems with their kidneys. They can’t handle too much calcium before one year.

29 tess casey { 08.21.14 at 3:54 pm }

and, the water used to boil eggs….excellent for your plants!

30 Al Segur { 08.21.14 at 2:33 pm }

Egg shells dumped from a boat, simulate minnows(shiners), and draw fish.

31 KN Charlton { 08.21.14 at 1:45 pm }

My parents used to crumble them and feed them back to the chickens! We always had good eggs so it must have worked. Dad said it gave them some calcium!

32 Stu { 08.21.14 at 1:14 pm }

I dry shells and then pulverize in a blender to be used in plant mix.

33 DaWanda { 08.21.14 at 1:21 am }

I put them in the microwave for three minutes and crush them. I add them to the holes I plant my tomatoes in to prevent end blossom rot. I also add them to my bird seed and potted plants.

34 Mary { 08.20.14 at 8:17 pm }

In one of her books, Adele Davis suggested soaking crumbled egg shell in fresh lemon juice for several days. Try refrigerating this calcium extraction in a glass jar over several days; even a week. Add to fresh O.J., smoothies, salad dressings and other foods.

35 marilyn { 08.20.14 at 2:21 pm }

When scissors need sharpening, just cut thru repeatedly, over full length of scissors, wash scissors well afterwards. (Can also be done w/dull knives, but it is possible to cut hand holding egg – extra caution on those). m

36 Iva Costa { 08.20.14 at 1:30 pm }

I read about the egg shells which have add more for what I alredy knew! Thanks good information! A+

37 Cyn { 08.19.14 at 9:28 pm }

Use the egg shells as plant starters also ..
Step 1 clean ..
Step 2 fill with dirt.
Step 3 add seed

Allow seed to grow then transplant into ground.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
