  2. 2. Lignocellulosic feedstock  Wood  primary (native)  plantation  primary forest waste  secondary processing waste  Agricultural residues  straws (wheat, barley, rice)  bagasse (sugarcane, sweet sorghum)  stover (corn, milo)  Municipal waste  Waste paper your contact: Dirk Volkmann – dirk@volkmann-consult.de
  3. 3. - complexity of the raw material - composition: target: cellulose (35 – 50%) to separate the lignin and the hemicellulose hemicellulose from the cellulose and to (20 - 35%) break up the protective skin of the cellulose to lignin make it predisposed for (10 – 25 %) enzymes your contact: Dirk Volkmann – dirk@volkmann-consult.de
  4. 4. cellulosic technologies acid hydrolysis enzymatic concentrated acid processes hydrolysis dilute acid hydrolysis lignocellusic removal (pretreatment) ethanol of the lignin present in new acid hydrolysis lignocellulosic feedstocks biomass synthesis gas production of ethanol from biomass synthesis gas your contact: Dirk Volkmann – dirk@volkmann-consult.de
