The waste eggshells are put into water and then ground to separate the eggshell from the protein membrane. [10] Then the ground eggshell is placed in a separate vessel where air is injected into the water flow. The air and water mixture causes the lighter component (protein membrane) to float and the heavier (calcium carbonate eggshells) to sink.
Eggshell membrane is derived commercially from the eggshells of industrial processors. In the United States, egg-breaking facilities generate more than 24 billion broken eggshells every year. [ 1 ] There are various ways in which the membrane is separated from the shell , including chemical, mechanical, steam, and vacuum processes.
These types of eggs can also be very small and fragile. [citation needed] While many reptiles lay eggs with flexible, calcified eggshells, there are some that lay hard eggs. Eggs laid by snakes generally have leathery shells which often adhere to one another. Depending on the species, turtles and tortoises lay hard or soft eggs.
A baby crocodile has an egg tooth on the end of its snout. It is a tough piece of skin which is resorbed less than two months after hatching. Crocodile eggs are similar to those of birds in that they have an inner membrane and an outer one.

Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell.

Egg repair is the process of repairing the eggshell of a live egg, particularly for live birds as eggs may be damaged by parent birds with sharp claws that can punch holes in a fertilized egg. Eggs are repaired by gluing a piece of another egg of the same shape over the top. [1] Cracked eggs can be repaired by applying white glue. Broken or ...
