Can I Compost Clam shells?
Yes
Clam shells can be composted.
What to Know
- Clam shells are compostable but break down very slowly
- They are high in calcium carbonate, which can help balance the pH of your compost
- Shells don't contribute much in terms of nutrients but can improve soil structure
Tips
- Crush or grind the shells into smaller pieces to speed up decomposition
- Use sparingly as they take a long time to break down
- They're best mixed with other compostable materials rather than added in large quantities at once
