5 SEKAB focus 40 % cellulose 26 % hemicellulose 25 % lignin Scaling up and economy - productivity in continuous operation - raw material flexibility - plant design/ investment costs - scaling up of bioprocesses - process integration Acid / Enzymes Yeast CO 2 CO CO 2 2 CO 2 CO 2 Hemicellulose and Cellulose Monosugars C6 + C5 CH 3 -CH 2 -OH CH 3 -CH 2 -OH CH 3 -CH 2 -OH CH 3 -CH 2 -OH CH 3 -CH 2 -OH Ethanol + CO 2

6 E-Tech Biofuels Process Base Configuration

7 E-Tech business strategies Technology development and verification in demo plant on contract basis and in collaborations with universities, institutes and companies Revenues from: Consulting services such as feasibility studies Process engineering and preengineering design packages Technology licenses

8 Sulphite liquor ethanol plant Demo plant cellulosic ethanol

9 Demo Plant Fully integrated from cellulose feedstock to distilled ethanol Operated 24h/ 7d Dilute acid + enzymatic hydrolysis Two continuous flow-through thermochemical reactors Five 10 m 3 bio-reactors Yeast cultivation GMM certified Flexible Process configurations Feedstocks Other biorefinery applications (sugar platform) Capacity, 2 tons of dry wood chips / 24 h

10 Demo Plant 1. Raw material intake 2. Feeding vessel 3. Steaming and impregnation 4. Pretreatment 5. Neutralisation and inhibitor control 6. Enzymatic hydrolysis and fermentation 7. Yeast propagation 8. Distillation 9. Product tank 10. Filter press 11. Solid material to incineration 12. Liquid to incineration/ biogas production 13. Evaporation Equipment

11 Achievements Experience > hours of accumulated operation High availability, good control Continuous uninterrupted operation for 3 weeks Yields from spruce wood (glucose from cellulose % of theoretical) ~ 50 % for 2-stage dilute acid > 70 % for enzymes. > 4 % ethanol concentration. GMM C5 - yeast succesfully tested Increasing number of feedstocks

12 What is unique for the E-Tech Process Combination of: Patent protected process solutions/ methods/ integrations 12 Patents/ applications Process know-how Extensive experiences from operation of continuous demo plant A strong CelluloseTechnology Platform with an extensive research and industrial network. Collaborations with; Universities and Institutes national and international Biotech companies active in development of enzymes and pentose fermentation Engineering companies and equipment suppliers with extensive experience from cellulose and ethanol processing

13 Cellulose feedstocks - Pine - Birch - Poplar - Tops and Wood chips Spruce branches Pulp fibers Sugarcane bagasse Wheat straw Corn cobs Corn stover Strong focus on wood cellulose in Swedish ethanol research programmes Increasing focus on agro materials

14 Integration options Biorefinery Cellulose-annexe Energy Raw material Energy Integration/exchange Biomass Energy Raw material Integration options 1 st generation ethanol plant Chemical plant Heat & power Pulp & paper Products
