This paper explores the detailed study of calcium carbonate (CaCO3)
and its different origins such as naturally derived calcium carbonate (CaCO3),
calcium carbonate (CaCO3) obtained from different eggshells and
their various extraction methods. In this work, attempt has been made to add
the eggshell powder as filler to various polymer matrix and applications of
eggshells in various sectors. A growing effort has emerged to use bio-fillers
as a replacement for synthetic once in an attempt to reduce cost. Recently,
eggshell filler (ESF) has raised tremendous attention in polymer industry due
to its high calcium carbonate (CaCO3) content, which shows a great
potential to substitute conventional mineral filler like talk, calcium
carbonate and china clay. Percentage of calcium carbonate content varies from
different types of eggs. Hybrid hen eggshell can be utilized as it contains 95%
by weight of calcium carbonate (CaCO3) and 5% by weight of organic
materials. Eggshell filler can be used as an alternative for commercial grade
calcium carbonate filler. Also the various uses of eggshells in nutrition and
medicine and it can be used for different purposes that minimize their effect
on environmental pollution.
