2 2 BIOREFINERY CONCEPT THE CIMV PROCESS Based on the oil refining model. Promote 100% of the non-food Biomass in Biofuels and/or Bioproducts. High feedstocks fexilibility (straw, bagasse, hardwood, etc.). bio-based products : Biolignin TM, Cellulose pulp, C 5 sugars syrup..

3 3 CIMV PROCESS : ORGANOSOLV TECHNOLOGY 9 Patents Raw Material (wood, straw, bagasse, ) Mechanical conditioning CIMV 1 Organic refining Sugars & Lignin CIMV 3 Organics acids recycling Cellulose CIMV 2 CIMV 6 CIMV 4 & 5 Delignification Separation lignins / sugars Deacidification CIMV 7 Washing Enzymatic hydrolysis BIOLIGNIN TM C 5 SUGARS SYRUP CELLULOSIC PULP GLUCOSE CIMV8&9

4 4 CIMV PROCESS : 3 DIFFERENT OUTLETS Option 3: 1: 2: Biolignin / / Cellulose BioEthanol Glucose Pulp / Xylose / Xylose Pulping Straw/ Wood Alkaline/ neutral washing Option Option Option 3 : Biolignin 2 : Biolignin 1 : Biolignin / Cellulose / Glucose / BioEthanol Pulp/ / Xylose Bleaching Crushing and Drying Dust Extraction Organic acid recovery Delignification Cellulose deacidification water cellulose P1 Hydrolysis Co-Hydrolysis C5/C6 Wet Lap Glucose P2 Cellulose Pulp ETHANOL distillation Hydrolysis Organic acid evaporation Lignin dispersion Lignin Filtration C5 sugar concentration C5 sugars Hydrolysis Co-Fermentation C5/C6 Xylose Xylose stillage Biolignin C5 sugar syrup purification Lignin Drying

5 5 CIMV PROCESS ADVANTAGES: FEEDSTOCK FLEXIBILITY ( straws, hardwood, bagasse ) ~ 100%SOLVENT RECYCLING NO DEGRADATION PRODUCT PURITY AND SPECIFIC PROPERTIES OF THE PRODUCTS
