In Calgary, put this in the
Green cart — Compost
Eggshells go in the green cart.
Also searched as: egg shells.
Why the green cart?
Eggshells are essentially calcium carbonate and add minerals to the finished compost. The industrial process grinds and breaks them down completely — no need to crush or rinse them first.
Get it right
- Shells, cartons (if paper) and even the box liner can all go green together.
- Gardeners: crushed eggshells also work directly in home compost or as slug deterrent around plants.
