Eggshells are something that many of us simply throw into the bin without a second thought. While they’re not great to eat, there are many other ways eggshells can be used.
Give these ideas a try before sending them out with the rubbish.
1. Clean your frypan
Crush the shells into small pieces, and add them to your frypan or grill along with some hot water, and then scour away. The shell pieces will help remove the stubborn, baked on crust.
2. Sharpen your blender blades
Freeze your eggshells for approximately 30 minutes, then add to your blender and cover with water. Switch it on and blend away, and your blades will be nice and sharp again. You can then add the mixture to your compost!
3. Garden fertiliser
Use a mortar and pestle to finely crush your egg shells, and then sprinkle into your soil. You can store this mixture in an airtight container.
4. Make chalk
Make sidewalk chalk out of your eggshells by crushing or blending them into a fine powder, and adding flour and water until you reach a mixture with the consistency of wet sand. Roll it into a small log and wrap in paper towel. Allow to dry for two or three days before unwrapping. You could add some food colouring to the wet mixture to make different colours. The grandkids will love it!
5. Feed them to your chickens
It sounds a bit strange, but if you have chickens, you can actually feed your eggshells back to them. They are an excellent source of calcium and will actually improve the condition of their eggs.
6. Brew them with your coffee
Another one that sounds rather odd, but brewing your coffee with eggshells can lower the acidity and give you a smoother tasting cup of Joe.
It’s important to boil your eggshells first, as they can carry salmonella bacteria. Simply crush them and add them to your plunger or percolator and brew as usual.
7. Plant seedlings in them
Rinse out your eggshells and use them to start out your seedlings. They are nutrient rich and excellent for plants, and you can simply plant them into the ground like an eco-friendly, biodegradable container.
8. Compost them
Throw your eggshells into your compost bin for a much-needed calcium boost.
