Maybe it’s just good old-fashioned thriftiness, but it falls on us all to take a second look at things we might have thrown away yesteryear.

Fertilize the Garden

Improve the garden with help from your breakfast. Rinse and remove the clear inner membrane of eggshells. Store dry eggshells in a large, secure container. We promise it won’t stink. (If you’re eating these tasty omelets regularly, the jar will fill up quickly!) Mash them down to fine bits with a steel or wooden spoon. Then you can load up on eggshells again. Once the spring temperatures soften the soil, you can sprinkle and mix the ground eggshells you’ve been saving into your garden for a great source of calcium carbonate for the soil. An added bonus: they reduce soil acidity.

Create a Non-Toxic Abrasive Cleaner

You vowed to steer clear of powdered household and industrial cleaners (goodbye, Ajax!) but have no clue what to use instead of these powerful chemicals. We spotted a non-toxic and gentle-on-your-nose cleaner on

Firstly, collect the eggshells of about a dozen eggs. Once you’re ready to prepare the cleaner, wash the eggshells and line them up on a baking sheet. Dry the shells outside in the sun or on low heat in the oven for a few minutes. Use a mortar and pestle, coffee grinder or high-speed blender to blend into a fine paste. You should have about 1 cup of powder. In a mason jar, add 3 cups baking soda to the eggshell powder. To clean, just mix the powder with vinegar (or water). Use this formula on pots and pans (with baked-on food), shower doors (with months of gunk), toilet bowl rings and grout.

Start the Herb Garden of Your Dreams

Daydream about covering every inch of your winter home with happy, green indoor plants? Here’s one step to realizing that dream. For your next weekend brunch, cook up a super yummy egg dish (eggs benedict casserole is always a winner). When cracking each egg, cut the top of the shell and pour the egg out of the shell to preserve most of the length of the eggshell. Gently rinse before storing. Remember to save the egg carton—this is where your herb starter plants will grow.

Once the shells have dried, use a sharp needle or awl to poke a hole in the bottom of each (for water drainage). Place an eggshell in each carton divot. Fill each most of the way with soil. Place seeds into soil, according to seed-sowing instructions. Mist soil with spray bottle and keep carton in full sun. Water regularly and keep an eye out for sprouts. Once it’s time to transfer into a pot or garden, you can transplant as-is.

Yolk Separator

Don’t be fooled by the gadgets you see at the store. The best way to separate egg whites from yolks is to use a good old-fashioned eggshell. Crack an egg in half and slowly pour the white into a bowl. Once the white starts tugging at the yolk, use the jagged side of the eggshell to separate the white. And, hey, don’t discard that yolk either. Here are 36 things you can make with egg yolk.

Feed the Birds

You can also be an incredible neighbor to your local birds with this great tip from Birds and Blooms. When you have enough eggshells to cover a baking tray, bake them at around 250 degrees until dry. They will be brittle enough to crush easily. Spread the mixture in a feeder or on the ground for birds to munch on. It’s a great source of calcium for the birds—especially for females during the spring, prime time for laying eggs.

Clean Up the Sink

Most people want their kitchen sink strainer to be spotless—but you may want to consider keeping a few loose eggshells down there while you wash up. The eggshell pieces will help prevent food solids from going down the drain, and as the egg starts to break down it acts as a natural abrasive to help clean drain pipes.
