Bioethanol from biomass waste

  1. 1. Bioethanol from Biomass Waste Isroi (http://isroi.com)
  2. 2. Bioethanol Movie clip
  3. 3. Bioethanol  Renewable  Environmental friendly  Not compete with food and feed  Unblended bioethanol fuel or Blended with gasoline C2H5OH + 3 O2 → 2 CO2 + 3 H2O + heat
  4. 4. First Generation Bioethanol
  5. 5. First Generation Bioethanol Ethanol from sugar (sugarcane, etc) and amylum (starch, casava, corn, etc).
  6. 6. Second Generation Bioethanol
  7. 7. Why lignocellulose?
  8. 8. Why lignocellulose? Glucose Starch Cellulose Ethanol
  9. 9. Why lignocellulose?  Abundant  Renewable  Not compete with food and feet
  10. 10. Oil Palm Waste Abundant and un-use
  11. 11. Mass Balance in Oil Palm Mill 1 ton FFB 230 kg EFB
  12. 12. Problems and Challenges PurificationHydrolysis Fermentation Ethanol Waste water Lignocellulose Pretreatment
  13. 13. Pretreatment of Lignocelullose Mosier et al. (2005) Pretreatment: • Mechanical • Physical • Chemical • Biological • Combination Pretreatments have as a goal to improve the digestibility of the lignocellulosic biomass (Hendriks and Zeeman, 2008).
  14. 14. Advantages and Disadvantages Advantages Disadvantages • No chemical added • Take more times • Less energy used • Need more places • More environmental friendly Biological pretreatment of EFB by white-rot fungi compared with physical/chemical pretreatment
  15. 15. White-rot Fungi Enzymes produced by lignocellulytic fungi: • Laccase • Mangan Peroxidase (Mn P) • Lignin Peroxidase (Li P) White-rot fungi are the only known organisms that, to any extent, mineralize lignin to CO2 and water in pure culture (Gold and Alic, 1993)
  16. 16. Biological Pretreatment Untreated After pretreatment Visual Changes of OPEFB after pretreatment
  17. 17. MyDream EFB ETHANOL
  18. 18. Thank You
