At home, eggshells are dumped as waste. Do you know that eggshells are not food waste? Eggshells can be used for many purposes when they are broken to bits.
Upon closing the lid after putting eggshells in the Eggshell Grinder, the sharp blades inside break eggshells into pieces once you turn the lid with your hand. The eggshell powder can be seen through the lid & net of Eggshell Grinder.
Eggshell powder can be used as a nutritious fertilizer for plants. It can be used to remove old dirt on the surface of bowls and dishes. And it can be used as an eco-friendly detergent as well.
Use Eggshell Grinder to turn eggshells into a helpful resource.
