The Reality of Disposing of Eggshells: Hidden Risks

Omelettes generate eggshell waste that many people crush and rinse, assuming fine fragments will wash through. In practice, shell particles snag on moist residue and bind with grease, soap film, and food fibers.

Over time these rough pieces help anchor larger blockages. Abrasive edges can also contribute to wear in aging metal pipes. Always place shells in the trash or compost; keep them away from sinks to preserve clear drainage.
