11 Challenges for cellulosic ethanol production - process solutions High process yields Low operating costs All sugars to ethanol Feedstock specific reaction conditions Feedstock optimized enzymes Integrated enzyme production Low investment costs Sustainable process 11

12 Advantages of process integrated enzyme production Low substrate cost Enzymes are produced on lignocellulosic substrate. No additional utilities needed Process integrated No formulation and logistics Enzymes are produced directly where they are needed Process integrated production of enzymes is the most cost efficient way and leads to independence from enzyme suppliers. 12

13 Challenges for cellulosic ethanol production - process solutions High process yields Low operating costs All sugars to ethanol Feedstock specific reaction conditions Feedstock optimized enzymes Integrated enzyme production No external energy required Low investment costs Sustainable process 13

14 Energy consumption Low energy consumption in DSP 120% 100% New ethanol separation process with very low energy consumption 80% 60% 40% Based on Süd-Chemie technology Patented process and material 20% 0% Standard DSP 2G SC Technology SC Technology optimized With the innovative Süd-Chemie separation process up to 50% of energy can be saved in DSP. 14

15 Challenges for cellulosic ethanol production - process solutions High process yields Low operating costs All sugars to ethanol Feedstock specific reaction conditions Feedstock optimized enzymes Integrated enzyme production No external energy required Low investment costs Proven (bio)chemical process technology All scalable to production scale Sustainable process 15

16 Challenges for cellulosic ethanol production - process solutions High process yields Low operating costs All sugars to ethanol Feedstock specific reaction conditions Feedstock optimized enzymes Integrated enzyme production No external energy required Low investment costs Proven (bio)chemical process technology All scalable to production scale Sustainable process No Food-or-Feed issue Ethanol is nearly Carbon neutral Process is energy self sufficient 16

17 Sustainable cellulosic ethanol Process works flexible for different renewable feedstocks Production costs will be competitive to 1 st generation bioethanol Energy neutral: No additional fossil energy needed Nearly carbon neutral: GHG emissions reductions of about 95% compared to fossil fuels Domestic fuel production: More independence from fossil fuels Creation of green jobs and income for rural areas and agricultural industry No Food for Fuel competition and no additional land use The technology is mature and ready for commercialization. 17
