Creating biomass pellets using only Napier Grass (75%) and Coconut Shell (25%) is not only possible — it’s also efficient when processed correctly. This blend offers a balance between ease of pelletization, good energy output, and moderate ash content.

🔬 Estimated Properties of Napier Grass (75%) + Coconut Shell (25%) Pellet

✅ Why This Blend Works

• Napier Grass: Excellent binder, high volatile content.
• Coconut Shell: Improves energy value and pellet hardness, reduces ash.

🔁 Optional Optimization – Two-Ingredient Tweak

For better results:

• Napier Grass: 65–70%
• Coconut Shell: 30–35%

Improved Results:

• Ash Content ↓ to ~6%
• GCV ↑ to ~4500 kcal/kg
• Durability ↑ for industrial usage

⚙️ Essential Equipment

• Dewatering Screw Press (for wet Napier)
• Flash or Rotary Dryer
• Hammer Mill (<3 mm screen)
• Ribbon Mixer
• Ring Die Pellet Mill (1:6 to 1:8 ratio)
• Counterflow Cooler

💡 Best Practices

• Uniform grinding (<3 mm)
• Consistent moisture (12–15%)
• Final moisture <10%
• Use clean, sorted coconut shell (no husk)
