Integrated biorefinery for production of biodegradable film, bioethanol, and soda pulp from corn stalks

In traditional pulping, black liquor is burned in an alkali recovery system to produce energy. According the integrated forest biorefinery (IFBR) concept, hemicellulose partially pre-extracted prior pulp production generate value-added products. Corn stalks have a remarkable carbohydrate content (75% w/w), and thus were examined this study terms of IFBR concept. The hemicelluloses with hot water (90, 120, 135, 150 °C), NaOH, NaOH + NaBH4 (50, 70, 90 °C) for 4 h. charges 16.7, 26.7, 33.3% explored. extracts utilized bioethanol biodegradable films, papermaking pulps produced from solid fractions. Differences among groups identified via analysis variance, Duncan’s test was applied determine those differences that significant. results showed alkaline pre-extraction (26.7% at 50 removed 35.6% xylose stalk structure. liquid fraction collected °C gave 14.7% (g/100 g soluble material) yield bioethanol. Moreover, theoretical ethanol calculated as 89.4%. addition gluten nanocellulose xylan enabled high-quality films. Furthermore, fractions comparable properties control soda pulp.
