Abstract
In the context of increasing population, climate changes, and the depletion of energy resources, researchers have focused on the development of alternative renewable biofuels. Bioethanol has been identified as a biodegradable and environmentally friendly biofuel that gains much more interest as a future energy source. It is produced from various renewable resources including, starch, sugar, lignocellulosic materials, algal feedstocks, and agricultural/food processing waste by the fermentation process that contains four main sections including pretreatment, hydrolysis, fermentation, and downstream. Industrial fermentation processes are considered as an important biotechnological platform and there have been significant developments in order to improve conversion efficiency and reduce the capital and operation costs. This chapter focuses on the discussion of synergic studies from feedstock to life cycle assessment of bioethanol production as reported in the literature. © 2023 Elsevier Ltd. All rights reserved.
