Evaluating a wealth of quantitative data, Biofuels: Biotechnology, Chemistry, and Sustainable Development discusses different types of biofuels, the science behind their production, the economics of their introduction to the marketplace, their environmental impacts, and their implications for world agriculture. It broadens the discussion on biofuels beyond bioethanol and biodiesel, taking into account the data, ideas, and bioproducts that have appeared over the last 50 years. An Insider’s Look at the Biotech Industry Written by a seasoned expert in the biotech industry, the book analyzes in detail the present status and future prospects of biofuels, from ethanol and biodiesel to biotechnological routes to biohydrogen. It emphasizes the ways biotechnology can improve process economics as well as facilitate sustainable agroindustries and crucial elements of a biobased economy. The author also explores the additional innovations required in microbial and plant biotechnology, metabolic engineering, bioreactor design, and the genetic manipulation of novel biomass species of plants, such as softwoods and algae. The Role of Biofuels in the Future With over 1,000 references and nearly 200 graphs and tables of data, this well-researched, comprehensive work examines the past and present of various biofuels while considering the future of a biocommodity economy.

With the availability of the new technologies and advanced in research on the bioethanol fuel production, innovative raw materials have been explored. Biomass is biodegradable, sustainable, less CO2, CO, SOx, HC and NOX emissions sources as well as renewable and outstanding energy resource for the creation of steam and electricity, transportation fuel and manufacturing industries. In this study, banana and pineapple wastes were used as raw materials. Fermentation bioprocess has been made using yeast, amylase, cellulase and pectinase. Fermentation of banana and pineapple mash using the highest concentration of yeast showed the highest concentration of bioethanol. The use of the mixture (pulp and skin) fruit was more suitable than skin and pulp as it could reduce the cost of the whole production process. Chemical elements of the biofuels were affected by the different concentration of yeast, and different pH treated with rotten and fresh banana. The produced bioethanol from banana and pineapple biomass was of good quality following the ASTM standard and an interesting issue that can be used as environmental recycling process for waste management.

What role will biofuels play in the scientific portfolio that might bring energy independence and security, revitalize rural infrastructures, and wean us off of our addiction to oil? The shifting energy landscape of the 21st century, with its increased demand for renewable energy technology, poses a worrying challenge. Discussing the multidisciplinary study of bioenergy and its potential for replacing fossil fuels in the coming decades, Introduction to Biofuels provides a roadmap for understanding the broad sweep of technological, sociological, and energy policy issues that intermingle and intertwine. Copiously illustrated and with numerous examples, this book explores key technologies, including biotechnology, bioprocessing, and genetic reprogramming of microorganisms. The author examines the future of biofuels from a broader perspective, addressing the economic, social, and environmental issues crucial for studying the sustainable development of bioenergy. Each chapter begins with questions and provides the answers later in the chapter as key informational points. Embedded Science, Technology, Engineering, and Math (STEM) sections provide detailed derivations and equations for a subset of topics that can be found easily as buzzwords in popular media and on web sites. Together, the STEM topics form a thread of essential technologies and a guide to how researchers have established quantitative parameters that are crucial to the ever-growing biofuels database. With so much information scattered throughout the literature, it is often difficult to make sense of what is real and what is an optimistic selling of ideas with no scientific credibility. This book does an excellent job of filtering through volumes of data, providing a historical perspective on which to anchor the information, and outlining the strengths and constraints of the different biofuels.

This book explores a novel technique for processing biodiesel using lipase immobilization by encapsulation and its physical properties, stability characteristics, and application in stirred tank and re-circulated packed bed immobilized reactors for biodiesel production. The enzymatic processing of biodiesel addresses many of the problems associated with chemical processing. It requires only moderate operating conditions and yields a high-quality product with a high level of conversion and the life cycle assessment of enzymatic biodiesel production has more favourable environmental consequences. The chemical processing problems of waste water treatment are lessened and soap formation is not an issue, meaning that waste oil with higher FFA can be used as the feedstock. The by product glycerol does not require any purification and it can be sold at higher price. However, soluble enzymatic processing is not perfect. It is costly, the enzyme cannot be recycled and its removal from the product is difficult. For these reasons, immobilized enzymatic process has been developed which retains the advantages of the soluble enzymatic process and reuse of the enzyme is possible which decreases the enzyme cost, the biodiesel produced does not contain any enzyme residue and the activity of the enzyme can be increased by immobilization. The drawbacks of the immobilized enzyme process are mass transfer limitation, enzyme leakage, the lack of a versatile commercial immobilized enzyme and some of immobilization methods involve toxic chemicals. To overcome the drawbacks of the immobilized enzyme, an attempt is made to use a degradable biopolymer (κ-carrageenan) as a carrier for lipase immobilization.

The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.
