Grinding And Storing Egg Shells

So what is the simple secret? When it comes to storing egg shells, it’s all about grinding them up and storing them frozen!

Grinding or crushing egg shells down to a fine powder has more benefits than simply allowing for better storage. When it comes to using egg shells in your garden and flowers, the finer the egg shells are ground, the more quickly they will benefit your plants.

Whole or large egg shell pieces can take a long time to break down. Until they do, they can’t provide much in the way of nutrients to your soil or plants. But when you crush eggs shells into a fine grind, the powder-like substance is able to release its nutrients into the soil much more rapidly.

In fact, other than using a few slightly broken shells around plants to protect them from cutworms and slugs, the majority of the time you will be using egg shells, it is best to have them finely ground. So why not store them that way from the start?

It’s fast, easy, and best of all, allows you to compactly store them in your freezer. Even better, you can store them safely, with no worries of mold, bacteria or foul odors!

Two of the biggest issues with storing egg shells are safety and storage space. Especially if you are trying to store egg shells all winter long. When left out, egg shells can create a bit of a foul odor from the leftover egg remnants inside the shell.

If the smell wasn’t bad enough, they can also grow bacteria and mold. And then there is the issue of where to store all of the shells until you need them. But by simply grinding them up and plopping them into a storage bag in your freezer, both issues are solved in an instant!

To make our egg shells easy to grind, we place them on an old cookie tray. We then dry them out in the oven set on low for just a few minutes. We simply save our shells for a few weeks in a resealable bag until we have enough to dry them out on the tray.

This step can be omitted, but it makes the shells even easier to grind when completely dry. Next, using a basic hand-held coffee grinder (a blender works will work well too), you can chop up egg shells in an instant.

The grinder does a great job of creating a very fine powder that hand crushing simply can’t do. So fine that you can fit hundred and hundreds of eggs into a one gallon size freezer bag with ease. Affiliate Link: Basics Electric Coffee Grinder, Coffee Bean and Spice Grinder

One final note, always be sure to clean and sanitize your coffee grinder blades after chopping eggs in them. Warm soapy water will do the trick in a flash.
