Advances in 2nd Generation of Bioethanol Production presents a comprehensive overview of technologies and strategies for the conversion of lignocellulosic biomass. This includes issues like sustainable production, environmental and economic benefits, and the main hurdles for upscaling and achieving commercial viability. The book assesses the current biomass conversion technologies, their readiness level for commercial production, and applications of bioethanol in bioenergy and chemical feedstock. The essential conversion process of 2nd generation biofuels, including feedstock composition and pretreatment, is then broken down, with special focus on advantages and pitfalls of each feedstock and process. It also explores the advances and challenges of bioprocessing, hydrolysis technologies and simultaneous fermentation of pentose and hexose. Finally, it presents the current status and bottlenecks for industrial production of bioethanol, as well as its future prospects. Its interdisciplinary approach, drawing upon plant biology, chemistry, biochemistry, microbiology, and genetics, makes Advances in 2nd Generation of Bioethanol Production a must-have reference for researchers in academia and industry R&D. It allows them to compare challenges and opportunities of new technologies and identify the gaps where new technology is needed. Practitioners in the industry also benefit from the information on working principles, design and control of the bioethanol production process, highlighting areas where technology innovation and investment should be placed. Graduate students and researchers newly entered in this field find here a key-resource to thoroughly understand the process as well as the fundamentals of bioethanol and bioproducts production from lignocellulosic biomass. Presents fundamentals and state-of-the-art of available pathways for bioethanol and bioproducts production from lignocellulosic biomass Discusses key-challenges for large scale production of bioethanol, such as pretreatment and hydrolysis Covers the specificities of various feedstocks and processes, the role of microorganisms in fermentation, saccharification limitations and challenges in the C5 and C6 fermentation

Global Bioethanol: Evolution, Risks, and Uncertainties explores the conceptual and methodological approaches for the understanding of bioethanol technologies, policies and future perspectives. After a decade of huge investments made by big companies and governments all around the world, it is time to talk about the real conditions in which bioethanol will (or will not) evolve. Uncertainties and certainties are discussed and addressed to understand the futures of global bioethanol. The book analyses the evolution of bioethanol in the world's energy mix under technological, economic and commercial perspectives. It gives particular emphasis on the innovative trajectories of second-generation ethanol and their potential in different countries and regions. Future scenarios are proposed in order to evaluate the possible outcomes of ethanol in a global perspective. For providing a thorough overview of the bioethanol sector from different points of view, this book is a very useful resource for all involved with biofuels in general and bioethanol in particular, including energy engineers, researchers, consultants, analysts and policy makers. - Presents a thorough examination of the uncertainties surrounding bioethanol in the future global energy mix - Provides a data-driven and updated picture on the technological, economic, and market trends and scenarios for bioethanol - Offers a foresight analysis on the perspectives of bioethanol as a global commodity - Includes a prospective about who is going to lead the new trajectories in the global arena

Bioethanol and Beyond: Advances in Production Process and Future Directions discusses the advances in the production process of bioethanol, ranging from first to fourth generation bioethanol. Bioethanol is currently applied besides simple fuels (biofuel): it is mixed with other fuels, such as gasoline and diesel, and used for generating renewable fuels, such as hydrogen. Advances in the industrial bioethanol (first and second generation) chain point towards the co-energy generation, in situ, and the possibility of generating outside the industry via energetic densification of the residues. A biorefinery is suggested as a strategy to use the industrial residues by amplifying the products portfolio and, thus, collaborating with the process feasibility. The book covers the technological possibilities to produce bioethanol. These processes include the second generation with the use of structural sugars from the plant cell wall and residues from algae (third and fourth generation bioethanol). The fermentation process and contamination in the industrial fermentation is presented, as well as strategies for its control. Pretreatment technologies, enzymatic hydrolysis technologies, and the search for enzymes are described based on recent developments and finds. When it comes to commercialization, technical-analytical standards have been developed in order to control bioethanol quality, contributing to overcome technical barriers and providing product reliability. This book covers the most important tasks in the production process and future directions for the uses, which is a very useful source of information for everything involved in bioethanol science. In particular, this book will answer the questions of students and researches regarding bioethanol production process, as well as professionals in the industry supply chain.

Bioethanol is a versatile transportation fuel and fuel additive that offers excellent performance and reduced air pollution compared to conventional fuels. Its production and use adds little, if any, net release of carbon dioxide to the atmosphere, dramatically reducing the potential for global climate change. Through a sustained research program and an emerging economic competitiveness, the technology for bioethanol production is poised for immediate widespread commercial applications. Written by engineers and scientists providing a technical focus, this handbook provides the up-to-date information needed by managers, engineers, and scientists to evaluate the technology, market, and economics of this fuel, while examining the development of production required to support its commercial use.

Bioethanol Production from Food Crops: Sustainable Sources, Interventions and Challenges comprehensively covers the global scenario of ethanol production from both food and non-food crops and other sources.
