Biomass conversion plant has many components which are connected each other. Material and energy flow among the components, therefore we should grasp the detail of the balance (Figures 13-16). If there is a choke point, the flow stagnation causes to the troubles of opera­tion and low efficiency of the performance. (Masami UENO, University of Ruyku, Faculty of Agriculture, Okinawa, Japan).

5. Conclusion

The different kind of biomass considered as main source for biofuel (diesel-methane, etha­nol, compost — etc). The cost of extraction and blending is very effective point for use of bio­mass in addition to ability for use of all part from biomass as multipurpose.
