Abstract :The amount of eggshells (chicken, duck, ostrich, turkey, goose, and quail eggs) that go to waste every year around the world is frightening. Eggshells are foods with high nutritional value that should not go to waste. Chicken egg shells, which contain significant amounts of calcium and minerals, end up in landfills without further processing. As a by-product, it creates an important problem for producers both economically and ecologically. The purpose of this review is to summarize the results of various research articles on eggshell and to provide a reference for subsequent studies in this field and to expand the usage areas of eggshell. Numerous studies have shown that eggshells are an important material, a currently unused calcium store. Finding ways to use eggshells for nutritional and non-nutritional purposes not only reduces waste but also provides several economic benefits. A total of 83 sources were used in the review. In the compilation study, the studies on saving the eggshell from the waste position and transforming it into a material with high added value are summarized. It is a reference in studies to be conducted on alternative uses of eggshell.
