Abstract: This study evaluated water hyacinth as feedstock for bioethanol production. Among different organic and mineral acids tested on pretreatment of water hyacinth, H<sub>2</sub>SO<sub>4</sub> was found to be effective. Structural changes before and after pretreatment were evaluated by SEM, FTIR and XRD analysis. Various process parameters on hydrolysis of H<sub>2</sub>SO<sub>4</sub> pretreated water hyacinth were optimized. Under optimized conditions, bioethanol (0.292% w/v) was obtained with an actual efficiency of 59.3%.
