Francesc Rabanal - Chemistry & Biotechnology

  1. 1. CHEMISTRY & BIOTECHNOLOGY Francesc Rabanal University of Barcelonahttp://www.qo.ub.es/personals/frabanal.htm
  2. 2. CHEMICALS PLASTICS, FUELSCHEMISTRY: BIOTECHNOLOGY:PETROLEUM AGRICULTURE FEEDSTOCKS
  3. 3. BIOTECHNOLOGY and CHEMISTRY: A CLASSIC EXAMPLESEMISYTHETIC PENICILLINS FERMENTATION to obtain 6-aminopenicillanic acid (6-APA) or 7-aminocephaloesporanic acid (7-ACA) Chemical ans enzymatic processes: SEMISYTHETIC PENICILLINS and CEFALOSPORINS: Amoxicillin, ampicillin, cephalexin etc ca 30 billion euros 65% of antibiotic market
  4. 4. CHEMICAL INDUSTRY€ 1300 billion turnover; 10 million employeesMoving to GREEN Chemistry, WHITE Biotechnology: € 116 billion (2008) to 450 billion (2020) Sustainable methods Renewable stocks Reduce pollutants (greenhouse effect gases…) Save energy and water
  5. 5. KEY AREAS and EXAMPLES BIOMATERIALS Biodegradable polymers: poly(hydroxyalkanoates) (starch-based materials sugars, cellulose etc) synergy chemist/biotechnologist for product improvement (bioplastics)
  6. 6. KEY AREAS and EXAMPLESCHEMICAL COMMODITIES 1,3-propanediol, 3-hydroxypropionic acid, lactic acid (from corn sugar) succinic acid (paints, textiles, coatings…) from carbohydrates and biomass polyethylene (from sugar cane)
  7. 7. KEY AREAS and EXAMPLESNEW PROCESSES in development:polypropylene (from sugar cane)biobased terephtalic acid (furandicarboxylic acid, from sugar)1,4-butandiol (from renewable carbohydrate feedstock),use as a solvent, fine chemical, polymers (polybutyleneterephtalate)Adipic acid (from glucose polyurethanes, nylon 6,6)Acrolein and acrylic acid from glycerin
  8. 8. Example: Adipic acid from glucose Adipic acid from benzene (crude oil) O OH O H2 O2 HNO3 HO + OH O Adipic acid Adipic acid from glucose (renewable process) OH OH OH OH O OH O2 HO H2 HO OH OH OH O OH OH O OH OH O Glucaric acid Adipic acid Glucose
  9. 9. KEY AREAS and EXAMPLESBiofuels:Bioethanol: from sugar cane to starch/lignocellulosic sources enzymatic process to obtain glucose from cellulose, recycle agricultural waste (glucose is to Biotech like crude oil is to Chemical industry)Biodiesel: from inedible crops
  10. 10. Summary and ConclusionsClear synergies and expertise-sharing between Chemistryand Biotechnology to produce chemical commodities andbiomaterials.Cost-effective and sustainable processes are beingdeveloped and tendency will continue to expandBig Chemical Companies are complementary to Biotechs
