Eggshells are one of those kitchen waste products we tend to throw away without a second thought. However, what many people don’t realize is that this “waste” is actually a valuable source of nutrients, both for human health and for plant health. Reusing them is not only a smart way to reduce waste, but also a natural and economical way to reap real benefits.

Health Benefits

Eggshells are composed of 90% calcium carbonate, an essential mineral for maintaining strong bones and teeth. After proper disinfection and pulverizing, they can be consumed in small amounts as a natural supplement. To do this, simply boil the shells for 5 minutes, dry them in the sun or oven, and then grind them into a fine powder.
