1 The Second Generation of Fuel-ethanol ethanol Production Technology April

2 Category of Ethanol Raw Material Sugar Cane Cassava Corn Wheat Bagasse Molasses Starch Cellulose Application Beverage ETHANOL Industrial Fuel 2

3 Composition of Lignocellulosic Biomass Pentose (xylose), which is unfermentable by normal microorganisms, contained in biomass causes low yield. Agricultural Products e.g. corn Lignocellulosic Biomass e.g. bagasse (hemicellulose) Others Others lignin) cellulose starch hemicellulose 3

4 Feature of Technology Conventional technology lignin others C 6 Sugar Fermentation of C 6 Sugar by yeast etc C 5 Sugar yield increase Our new technology lignin others C 6 Sugar Fermentation of C 6 Sugar by yeast etc C 5 Sugar New microorganism can convert C 5 sugar to ethanol recombinant E.coli "KO11" 4 4

5 Demonstration Plant in Japan In In 2001, 2001, Marubeni & Tsukishima (TSK) (TSK) acquired the the exclusive right right to to sell sell and and use use Verenium Process with with KO11, KO11, in in Thailand, Malaysia, Indonesia and and Japan. Japan. TSK TSK has has developed BCI BCI Technology in in Japan Japan under under NEDO s technical development program. In In 2003, 2003, TSK TSK constructed the the demonstration plant, plant, which which can can produce the the ethanol ethanol from from the the construction waste waste wood woodby by 24h 24h continuous operation. Demonstration Plant in Ichikawa, Chiba *NEDO : New Energy and Industrial Technology Development 5Organization Semi-governmental entity under Ministry of Economy, Trade and Industry 5

16 Effects of Bagasse-to to-ethanol Process Process Merit Demerit Molasses-toethanol Process Bagasse-toethanol Process Plant Cost is lower. Raw material cost is stably low. Raw material cost fluctuates. Plant cost is higher Break-down of Ethanol Production Cost Profit Raw Material 4 2 Operation Cost. 0 Depreciation (Molasses-bagasse combination) Only molasses Molasses & Bagasse Only Bagasse Handling Cost of Bagasse Handling Cost of Bagasse 16

17 Expansion of Cellulose-to to-ethanol Project Present market Future market Sugar/Starch-toethanol Technology Raw Material: Sugarcane, Corn, Wheat Shortage of food Destruction of environment Market will mature. Cellulose-to to-ethanol Technology Raw Material: Wood chips, Corn stover, baggase Good to environment. Under development stage. Need more technology. Expand greatly Many of new cellulose-toethanol plants expect to be build. Various of new biotechnologies to be developed. The plant cost to be reduced. 17
