### 4. **Decorative Crafts and Art Projects**

Their unique shape and natural color make pistachio shells perfect for DIY crafts. Use them to create mosaics, picture frames, jewelry, or even decorative bowls. They’re an inexpensive, eco-friendly material for creative projects.

### 5. **Pet Bedding or Litter Additive**

Crushed pistachio shells can be mixed with pet bedding or litter to add absorbency and control odors. Always ensure the shells are cleaned thoroughly to avoid any residual oils that might affect your pets.

### 6. **Natural Drainage for Compost Bins**

Adding pistachio shells to your compost bin improves aeration and drainage, helping the compost break down more efficiently. Their tough texture prevents the pile from becoming too compacted.

### 7. **Non-Slip Surface for Walkways and Driveways**

Spread crushed pistachio shells over slippery outdoor surfaces during winter to provide extra traction. They act like natural grit, helping to prevent slips and falls on icy paths.
