What eggshells are good for

Updated on September 4, 2016

One of the easiest recyclables are eggshells. People have been using them for years, if not decades, as fertilizer, as calcium additive in their food/drink, and facials; they have been used to soothe itches and bug bites, why, eggshells have even made its way into the art world, they are use to make jewelry, vases, mosaics and mixed in paint to paint pictures. There are countless ways of using them in everyday life – some ways may surprise you while others may not. Before recycling them you need to wash the eggshells in warm water to make sure there is no egg whites remaining in the shell. Drying can be done by air or many recommend baking in the oven at 250 degrees for at least a good 10 minutes, oven bake if you are going to use them in food or drink.


To prepare your eggshells for usage you will need to crunch, crush or ground them up, depending on how they are used, as different applications will require your eggshells to have a different texture. If they are not going to be used right away it is best to store them in a glass container or jar with a good tight lid. Canning jars are good for this because they have a rubber gasket for tight closure.


Soil additive

Eggshells are a great additive to increase the calcium content in the soil of your vegetable garden. Calcium is important to plants specifically because it helps with cell wall structure, good strong stems and leaves, and with a healthy root system. Plants deficient in calcium show stunted growth of the leaves and roots. Sprinkling fine ground shells around and about your garden, not only will this feed your plants but discourages many plant feeding pests by slicing their undersides as they crawl across the shells. Needless to say, adding them to compost pile adds to the fertilizing quality of your compost. Eggshells also will help reduce acidity in your soil.

Egg the pans

Eggshells make a good abrasive for cleaning those tough messes off your pans and other household messes. Grind up those eggshells and add them to your dish soap with a little water; the scrubbing will be easier.

Grub killer

Do you have brown circular patches of grass in your lawn? You more then likely have grubs worms that are eating the grass roots. One of the cheapest way I found to get rid of them is to start saving empty eggshells and crushing them into semi-small pieces. If you don't eat a lot of eggs maybe one or two of your neighbor/s can help out, as it will take a whole lot of eggshells. Sprinkle your crushed shells, about three tablespoons, over each brown patch (you do not have to cover the brown patch). Just leave it and let Mother Nature do the rest of the job. I did this in October and let it winter over, in spring I turned the ground and planted new grass and have not seen a brown patch since.

Grandma's remedy

My grandmother used cracked eggshells in her coffee to take out the bitterness and would make this concoction of finely grounded eggshells dissolved in cider vinegar, she would let it sit for a few days in the cellar before moving it to the medicine cabinet. If we got a bug bite or scrape or itchiness while we were visiting, she would soak a piece of cotton or cloth and dap it on the spot.

Eggshell Tincture

Put on another face

I heard about this one a long time ago and tried it, it work pretty good. Grind the eggshells into a powder, whip about a one teaspoon into one egg white and use it as a facial. Let it dry and then wash off with water. Gives you that baby soft skin. You can also take about two tablespoons of mayonnaise and stir in one teaspoon of eggshell powder and wash with it; it get the pores cleaned out.

Pet friendly

Because eggshell are high in calcium I have heard of people using them as a supplement in their cat, dog and bird food, as well as a supplement for themselves; if you do use them this way made sure you bake in the oven at 250 degrees for at least 10 minutes or more to kill any viruses or salmonella.
