3 PRO.E.SA TM Steps 3000 m 2 dedicated to renewable Strong Partnership: ENEA Regione Piemonte Politecnico of Turin Novozymes Nedalco, Scouting, testing and development of technology on lab scale Construction and test on continuous pilot plant Construction of Industrial Demo t/y

4 PRO.E.SA Technology: the 3 pillars Agronomy Pretreatment Hydrolysis & Fermentation

5 Agronomy: main agronomic goals Our general approach: Respect of environment No competition Fuel Vs. Food Easy to insert into the traditional agronomic system and biomass market High yielding species High biomass bioethanol conversion Our approach to biofuel sustainability: Low input requirements biomass (chemicalsutilities) Optimization of agronomic systems (cultivationlogistic transportation)

9 PRO.E.SA Technology: the 3 pillars Agronomy Pretreatment Hydrolysis & Fermentation

10 Pretreatment Technology STEP 1 ( ) SCOUTING OF THE POTENTIAL AVAILABLE TECHNOLOGY IN THE LIGNOCELLULOSIC ETHANOL PROCESS CHAIN At conceptual level (through literature and patent analysis) At techno economical level through visits at the different potential technology provider (company and universities) STEP 2 ( ) DEVELOPMENT OF THE TECHNOLOGY AT BATCH SCALE Trial runs have been carried out with the aim to develop Chemtex improved version of Pretreatment technology STEP 3 ( ) DEVELOPMENT OF THE TECHNOLOGY AT PILOT SCALE New Pretreatment Process has been successfully run on the continuous pilot plant from June 2009

11 PRO.E.SA TM technology : conditions optimization Technology perform well with different biomasses

12 PRO.E.SA Technology: the 3 pillars Agronomy Pretreatment Hydrolysis & Fermentation

13 Hydrolysis and Fermentation STEP 1 ( ) SCOUTING OF EXISTING REACTOR DESIGN SOLUTION STEP 2 ( ) TEST RUN OF THE TECHNOLOGY ON EXISTING CHEMTEX REACTORS STARTING OF MODELING APPROACH. New process concept developed at lab scale allowed and simplified the problems connected to high solid load of the VISCOSTY REDUCTION with standard reactor and proper design. STEP 3 ( ) DEFINITION OF THE TECHNOLOGY AT PILOT SCALE New Hydrolysis Process has been successfully run on the continuous pilot plant from January 2010

14 Hydrolysis and Fermentation Advantages of new continuous high solid Viscosity Reduction concept: Possibility to work at dry matter contents up to 40% Very low energy consumption for agitation Material is liquefied after few hours (less than 8 h) even at low enzyme load Easy ph and temperature control

15 FLEXIBLE: Feedstock can be widely selected: energy crop and agricultural wastes LOW OPEX / CAPEX Possibility to produce cost competite EtOH in almost any geographical area PROVEN: Continuous pilot plant since June 2009 Industrial scale start up Q COMMITED PARTIES: Technology competitiveness is sustained by Chemtex and its partners continuous development effort
