Possibility of Using Eggshell in Industry

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.
