What are Empty Corn Cobs?
Empty corn cobs are the remnants of maize (corn) after the kernels have been removed. These cobs are a valuable by-product used primarily for biomass fuel and pellet production due to their high calorific value and availability.
Physical and Chemical Composition of Empty Corn Cobs
Physical Composition:
- Appearance: Hard, cylindrical structures.
- Size: Varies, typically 10-15 cm in length.
Chemical Composition:
- Cellulose: ~30-40%
- Hemicellulose: ~20-30%
- Lignin: ~15-25%
- Calorific Value: ~3,800-4,200 kcal/kg
