Recent Research from Shizuoka University Highlight Findings in Biofuel (Bioethanol Production From Paper Sludge By Subcritical Water Pretreatment and Semi-simultaneous Saccharification and Fermentation).

Researchers from Shizuoka University in Hamamatsu, Japan have conducted a study on the potential for bioethanol production from paper sludge (PS) obtained from paper mills. The researchers found that waste-paper-containing PS can be used as a raw material for bioethanol production, as the global waste paper utilization rate has increased. They used subcritical water pretreatment to selectively decompose enzyme inhibitors in the PS without generating other enzyme inhibitors, resulting in a significant increase in bioethanol yield. The researchers concluded that this method could enable the use of large amounts of PS as ethanol feedstock in the future. [Extracted from the article]
