What is the theoretical yield per acre and the calorific value (GCV) of Biomass Materials in India for biomass pellet production?

The values provided for yield per acre and calorific value (GCV) of biomass materials, such as Napier Grass, are theoretical estimates. These figures can vary depending on several factors, including soil type, climate, farming practices, and the specific region where the biomass is cultivated. Local conditions may lead to variations in both the yield and the calorific output, making it essential to consider regional data for more accurate assessments.

1. Napier Grass

  • Yield per acre: 130 to 150 tons per year
  • GCV: 3800-4200 kcal/kg
  • Ash Percentage: 2-3%

2. Mustard (Husk and Stalks)

  • Yield of Mustard Husk per acre: 0.5 to 1 ton
  • GCV: 3500-4000 kcal/kg
  • Ash Percentage: 6-8%
  • Yield of Mustard Stalks per acre: 1.5 to 2 tons
  • GCV: 3700-4000 kcal/kg
  • Ash Percentage: 7-8%

3. Wheat (Straw and Pod)

  • Yield of Wheat Straw per acre: 1.5 to 2 tons
  • GCV: 3500 kcal/kg
  • Ash Percentage: 6-7%
  • Yield of Wheat Pod per acre: Residue after wheat harvest
  • GCV: 3400-3500 kcal/kg
  • Ash Percentage: 5-6%

4. Rice (Husk and Straw)

  • Yield of Rice Husk per acre: 500 to 600 kg
  • GCV: 3200 kcal/kg
  • Ash Percentage: 12-14%
  • Yield of Rice Straw per acre: 2.5 to 3 tons
  • GCV: 3200 kcal/kg
  • Ash Percentage: 15-16%

5. Corn (Cob and Stalk)

  • Yield of Corn Cob per acre: 0.8 to 1 ton
  • GCV: 3800-4200 kcal/kg
  • Ash Percentage: 3-4%
  • Yield of Corn Stalk per acre: 1.5 to 2 tons
  • GCV: 3500-3700 kcal/kg
  • Ash Percentage: 5-6%

6. Sorghum (Cob, Straw, and Stalk)

  • Yield of Sorghum Cob per acre: Residue after harvest
  • GCV: 3600-3700 kcal/kg
  • Ash Percentage: 4-5%
  • Yield of Sorghum Stalks per acre: 2 to 3 tons
  • GCV: 3500-3600 kcal/kg
  • Ash Percentage: 5-6%

7. Sugarcane Bagasse

  • Yield per acre: 8 to 10 tons (after crushing)
  • GCV: 2200-2500 kcal/kg
  • Ash Percentage: 2-4%

8. Cotton (Husk and Stalk)

  • Yield of Cotton Husk per acre: 0.5 to 1 ton
  • GCV: 3600-3700 kcal/kg
  • Ash Percentage: 5-6%
  • Yield of Cotton Stalks per acre: 1 to 1.5 tons
  • GCV: 3500-3600 kcal/kg
  • Ash Percentage: 6-7%

9. Millets (Pearl Millet, Finger Millet, Small Millets)

  • Yield of Millet Stalks per acre: 1 to 1.5 tons
  • GCV: 3500-3700 kcal/kg
  • Ash Percentage: 4-5%

10. Forestry Biomass (Eucalyptus, Acacia, Pine, Cedar)

  • Yield per acre: 8 to 10 tons of wood per year
  • GCV: 4300-4500 kcal/kg (depending on the type of wood)
  • Ash Percentage: 0.5-1%

These values are adjusted to reflect typical yields from Indian agricultural practices, helping optimize biomass pellet production for energy and industrial use.
