6 Amazing ways to reuse eggshells: Don't throw them away!

After fixing yourself some scrambled eggs or if you’ve used some eggs to bake a cake, you may have instinctively reached your hand towards the trash can to drop the eggshells in there. Hold on! Don't throw away the eggshells: you can recycle and reuse them in many beneficial ways. If you take full advantage of this and other components of your kitchen, you could achieve a more sustainable life.

The eggshell, which you have probably been throwing away until now, is made up of essential minerals such as zinc, phosphorus, manganese, iron, and, mainly, 90% calcium, an essential mineral for bones, teeth, the cardiovascular system and other organs. It can be used as a natural beauty ingredient and even as a plant fertilizer.

If you’d like to be more environmentally friendly, perhaps you’ve heard about the Zero Waste philosophy. Its followers work for the conservation of all the natural resources in many ways: responsible production, sensible consumption, reuse and recovery of products, packaging, and materials, all without burning items and avoiding discharges to the land, water, or air that can threaten the environment or human health. Eggshells are one of the most common wastes that can be easily reused.

Before using the shells, it’s a good idea to make sure they’re clean and free from bacteria. For that purpose, rinse the shells inside and out, making sure to remove any residue or membrane that may be stuck to the inside. Then boil the shells, dry them, and take them to the oven on medium heat for 10 minutes. Crush until powdery and use.
