Introduction and Background of the study

Eggshell, as for what we know, is the outer covering of an egg. According

to Sonenklar, the US food industry generate 150,000 tons of eggshell wastes per

year. The percentage on how the eggshells are disposed are 26.6% as fertilizer,

21.1% used for animal feeds, 26.3% being thrown in municipal dumps, and

26.0% used for other purposes. The eggshell is mostly made up of calcium

carbonate. It is the ingredient which makes the egg shells strong and hard. A

good quality eggshell will consist of an average of 2.2 grams of calcium. Also, the

membrane of it is a valuable source of protein. When separated, both products

have an array of uses.

Calcium carbonate is insoluble …show more content…
