What can I use my discarded eggshells for at home? Why not use eggshells to make alternative packaging for eggs?
In this project, I tried boiling, baking, stirring and drying eggshells and mixing them with agar and other materials to make packaging material for eggs.
The material can be reused as a base for eggs and, on the reverse side, as a coaster for crockery. After repeated use, the material can be dissolved directly in water and used as a good fertiliser for plants.
The use of this material can be a good solution for the disposal of eggshells, which can be reused as a product. In addition, it can be easily broken down after use, and the entire process creates a cycle that is very environmentally friendly.
