Compost or Not

Can I Compost Egg shells?

Yes

Egg shells can be composted.

What to Know

  • Eggshells are an excellent addition to compost
  • They're rich in calcium carbonate, which helps balance soil pH and provides nutrients for plants
  • Eggshells break down slowly, so they continue to enrich soil over time

Tips

  • Rinse eggshells to remove any residual egg white to prevent odors
  • Crush the shells into small pieces to speed up decomposition
  • For even faster breakdown, you can bake and grind them into a powder before adding to your compost
