Eggshells Utilisation in Polymer Composites

The outer covering of a hard shelled egg is known as eggshell. These are obtained from various sources like egg stations, chicken hatcheries industries and homes in different weights. It is a kind of waste which is considered not be used anywhere. It can produce hydroxyapatite which is considered most effective component of bone. This can have applications in medical supplements, bone graft substitute, floor tiles and in cements in order to improve strength but here discussion is limited to polymer composite. In composite fabrication egg shell waste is utilized, as it not only enhances the strength of composite but also provides us solution for the proper disposal waste egg shell. This review paper presents the brief insight of utilization of egg shell waste in polymer composite so as to improve its strength. From this review paper it may be concluded that research on tribological behavior of egg shell is less so it can be implemented in different sectors like metal matrix composite etc.
