Most of us are used to tossing eggshells into the trash without a second thought, but did you know that these common kitchen scraps have a surprising number of uses? From garden fertilizer to natural cleaning agents, eggshells can be repurposed in many beneficial ways. Let’s explore why you should start saving your eggshells and how to use them effectively around your home.
Nutritional Value of Eggshells
Eggshells are made almost entirely of calcium carbonate, the same material found in lime, which is used to enrich garden soil. Just half an eggshell can provide enough calcium to meet the daily requirements for adults, making it a valuable resource for home health remedies and gardening.
Uses for Eggshells in the Garden
-
Soil Amendment: Crushed eggshells can be sprinkled directly into the soil to add calcium. This mineral helps plants develop strong cellular walls and is particularly beneficial for tomatoes and peppers, which are prone to calcium deficiency.
-
Seed Starters: Half an eggshell can be used as a biodegradable pot for starting seeds. Simply fill it with soil, plant your seed, and place it in an egg carton for stability. When the seedlings are ready, you can plant them directly in the garden, shell and all.
-
Pest Deterrent: Scatter crushed eggshells around your plants to deter soft-bodied pests like slugs and snails without using harsh chemicals.
Household Uses for Eggshells
-
Natural Cleaning Abrasive: Ground eggshells make a non-toxic abrasive for tough cleaning jobs. Mix them with a little soapy water to clean pots and pans without scratching them.
-
Coffee Enhancer: Adding crushed eggshells to coffee grounds can help reduce the bitterness of coffee. The shells help clarify the coffee by trapping grounds and absorbing acids.
How to Prepare Eggshells for Use
-
Clean the Shells: Rinse the eggshells in warm water until all the egg white and yolk are removed. You can boil them for a few minutes to ensure they are sterilized.
-
Dry the Shells: Spread the clean eggshells on a baking sheet and place them in an oven at 200 degrees Fahrenheit for about 10 minutes to dry completely.
-
Crush or Grind: For most uses, you’ll need to crush or grind the eggshells. Use a mortar and pestle, a spice grinder, or a rolling pin.
Conclusion
Eggshells are a surprisingly versatile and valuable resource that you’ll think twice about throwing away after discovering their many benefits. Whether enhancing your garden or finding eco-friendly solutions for home cleaning, eggshells can play a multifunctional role in your daily life. So next time you crack an egg, think about how you might reuse that shell to benefit your home and garden!
