This study evaluates three bioethanol production pathways that are composed by saccarification and fermentation process (SFP), gasification and chemical synthesis process (GCP), gasification and biosynthesis process (GBP). These pathways are designed by process simulator PRO/II, and these material and energy balances are calculated. From the simulation results, the CO2 emission reduction of each process is evaluated. It becomes clear that the CO2 emission reduction of the process via syngas is larger than that of the process via sugars. The ethanol yield of GBP is the maximum, and GBP can support oneself a power and thermal energy in the process. In three processes, therefore, the CO2 emission reduction of GBP is the largest. The ethanol yield of SFP and GCP is almost the same. Because the residue including lignin contains moisture, the thermal energy from which SFP can be recovered is not large. On the other hand, GCP can use the thermal energy generated by chemical synthesis for the power production. It is indicated that GCP has the possibility of increasing the CO2 emission reduction more than SFP.

The economic impacts, CO<SUB>2</SUB> emission, and change in industrial structures using rice husk power plant in Japan were investigated using input-output table of Japan. The direct and second economic impacts by investment to the rice husk power plant sector were 1.5 times higher than that to the power sector. The flow of money shifted to the agriculture, forestry and fisheries sector during introduction rice husk power plant. Increasing rate of using rice husk power plant induce the high-value added and the low CO<SUB>2</SUB> emission society with a very little change in industrial structure.
