| Feedstock Type | Energy Content (MJ/kg) | Typical Applications | Sustainability Considerations |
|---|---|---|---|
| Wood Pellets | 15-18 | Heating (residential, commercial, industrial) | Sustainable forestry practices, transportation emissions |
| Agricultural Residues (Straw) | 12-15 | Combined Heat and Power (CHP), Biofuels | Soil nutrient depletion, transportation distances |
| Energy Crops (Miscanthus) | 14-17 | CHP, Biofuels | Land use change, fertilizer requirements |
| Food Waste | 8-12 | Anaerobic Digestion (Biogas) | Waste collection and sorting, digestate management |
Beyond these examples, the development of advanced biofuels from non-food biomass sources represents a promising avenue for reducing reliance on fossil fuels in the transportation sector. These technologies are still evolving, but hold the potential to significantly contribute to a more sustainable energy system.
Biomass Heating Systems: Technologies and Efficiency
