Abstract

Eggshells which are very easily discarded as waste are very rich source of calcium. This calcium if utilized properly can turn out to be a boon rather than a waste material. The first step is collection of egg shells of different birds in ample quantity. These shells are then pretreated and then subjected to pulverization to obtain a fine egg powder. From this egg powder calcium extraction is carried out and comparative study of calcium obtained from different bird egg shells is done. The powder obtained can be used as a fertilizer, for plant growth stimulation and various other applications. As this waste is calcium rich it can be used as filler in situ with different polymers and its mechanical properties can be tested using a universal testing machine (UTM). The properties that can be tested are tensile strength, compressive strength, elongation %. Also impact strength can be tested using Izod Impact tester.
