You can put raw eggs into your compost bin. However, you must keep the carbon to nitrogen ratio of your compost bin balanced. Composting ingredients are often referred to as "greens" and "browns," indicating whether they are primarily nitrogen- or carbon-based.
Beside above, how long does it take for eggshells to biodegrade? three years
In this manner, are eggshells biodegradable or nonbiodegradable?
Eggshells are slightly soluble mineral wastes. Calcium carbonate and similar materials make them up. They are not biodegradable. No biological processes are involved.
What is the shell of an egg made of?
Eggshell is made almost entirely of calcium carbonate (CaCO3) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out bacteria and dust.
