Production of Bioethanol Using Waste Biomass

In the present study, the most common sources of starch and sugar are used in the production of bioethanol, such as maize, wheat, sugarcane, and sugar beet. The different ways of converting these sources into bioethanol, such as saccharification and fermentation, which are critical stages in the transformation of starch and sugar into bioethanol, are also investigated. The chapter also examines all the steps and methods involved in the use of the most common raw material, i.e., lignocellulosic biomass for the production of bioethanol, and focuses on the study of pretreatment, enzymatic hydrolysis, fermentation, distillation, and purification. The study is followed by the issues associated with the utilization of lignocellulosic biomass for bioethanol production, such as farming leftovers, forestry refuse, and specialized energy crops. This book part discusses the present status of research on the use of palm tree residues, rice straw, and citrus peel as raw materials for the production of bioethanol, in addition to the production techniques.
