Eggshells are composed primarily of calcium carbonate. In most home compost sytems, whole or roughly crushed shells can take six months to over a year to fully break down, often remaining in large fragments. This limits how effectively their nutrients are put to practical use. Refining the shells into a fine, consistent powder allows for more immediate and practical use.
