Characterization of rice husk varieties in Uganda for biofuels and their techno-economic feasibility in gasification

- Low bulk densities and lignin necessitate use of binders for husk densification.
- The C/N ratios are higher than required for either biogas production or composting.
- Ash and non concentration of husk generation suit downdraft gasification systems.
- Electricity production cost using 250 kW rice-husk gasifier system is US$0.22/kW h.
- Electricity production cost using 250 kW diesel engine system is US$0.36/kW h.
