Traditional agriculture and emerging biofuels technology produce a number of wastes and by-products, ranging from corn fiber and glycerin to animal manure, that have the potential to serve as the basis for additional sources of bioenergy that includes both liquid biofuels and biogas. Biofuels from Agricultural Wastes and Byproducts is the first book to focus solely on the production of biofuels primarily from agricultural waste and by-products. The book is divided roughly into two sections. The first section looks at liquid biofuel production from agricultural byproducts, densification of agricultural residues, and the delivery from farm to processing plant of waste and byproducts for use in biofuel production. The second section focuses on anaerobic digestion of food and animal wastes, microbial diversity, molecular and biochemical aspects of methanogensis. Together these sections solidify Biofuels from Agricultural Wastes and Byproducts as a definitive source of information on the use of agricultural waste and by-products in biofuel production.

Biotransformation of Agricultural Waste and By-Products in the 4F Economy: The Food, Feed, Fiber, Fuel (4F) Economy presents an evaluation of plant species better exploitable for a particular transformation. As crops are already covering large parts of cultivable soils, is it is not conceivable to try to extend the cultures beyond the limit of available soils, but a further increase in productivity is not easy to obtain. The book discusses advances in technology and plants design which support the exploitation and valorization of vegetable and fruit by-products through fermentation (feed-batch liquid fermentation, solid-state fermentation) in bio-based bio-chemicals/biofuels production. Pathways in the biosynthesis of fibers, sugars, and metabolites are provided with a focus on the lifecycle of bacteria, yeasts, and even plant species. The text analyzes cellular structures and the organization of cell walls in order to show which polysaccharides offer more favorable fermentative processes and which are detrimental. Provides an overview of all plant based biosources Includes examples of biochemical/biofuel production from plant waste Discusses the production of enzymes used in the plant fermentation processes Explores the new fermentation technologies and production of chemicals and fuels from various plants

Materials from renewable resources are receiving increased attention, as leading industries and manufacturers attempt to replace declining petrochemical-based feedstocks with products derived from natural biomass, such as cereal straws. Cereal straws are expected to play an important role in the shift toward a sustainable economy, and a basic knowledge of the composition and structure of cereal straw is the key to using it wisely. Cereal Straw as a Resource for Sustainable Biomaterials and Biofuels: Chemistry, Extractives, Lignins, Hemicelluloses and Cellulose provides an introduction to straw chemistry. Topics discussed include the structure, ultrastructure, and chemical composition of straw; the structure and isolation of extractives from the straw; the three main components of straw: cellulose, hemicelluloses, and lignins; and chemical modifications of straw for industrial applications. This book will be helpful to scientists interested in the areas of natural resource management, environmental chemistry, plant chemistry, material science, polysaccharide chemistry, and lignin chemistry. It will also be of interest to academic and industrial scientists/researchers interested in novel applications of agricultural residues for industrial and/or recycling technologies. Provides the basics of straw composition and the structure of its cell walls Details the procedures required to fractionate straw components to produce chemical derivatives from straw cellulose, hemicelluloses, and lignins Elucidates new techniques for the production of biodegradable materials for the energy sector, chemical industry, and pulp and paper business

Biomass is a renewable resource, whose utilization has receivedgreat attention due to environmental considerations and theincreasing demands of energy worldwide. Since the energy crises ofthe 1970s, many countries have become interested in biomass as afuel source to expand the development of domestic and renewableenergy sources, reduce the environmental impacts of energyproduction provide rural prosperity for its poor farmers andbolster a flat agricultural sector. Biomass energy(bioenergy) can be an important alternative in the future and amore sustainable energy. In fact, for large portions of therural populations of developing countries, and for the poorestsections of urban populations, biomass is often the only availableand affordable source of energy for satisfying basic needs ascooking and heating. The focus of this book is to present a historical overview,country perspectives, the use of biomass to produce biofuels, thecurrent and upcoming sources of biofuels, technologies andprocesses for biofuel production, the various types of biofuelsand, specifically, the ways and means to make biofuel productionsustainable, economically feasible, minimize environmental damageand to deliver on its many promises. The Energy and Environment book series from ScrivenerPublishing and series editor, James G. Speight, aims to cover theenvironmental impacts and social concerns of energy production inits various forms. This first volume in the Energy and theEnvironment series offers a comprehensive coverage of one ofthe fastest-growing and most important sources of energy,biofuels. Future volumes will cover oil and gas, wind andsolar energy, and their environmental aspects.

Biomass is a continuously renewed source of energy formed from or by a wide variety of living organisms. Through biochemical and thermochemical processes, it is converted into gaseous, liquid or solid biofuels, which already meet a significant share of the current world energy needs. Because of their contribution to the sustainability of energy supply, reduction of green house gas emissions as well as local employment and energy self-reliance, research interest and activity in enhancing biofuel energy output, efficiency and performance remain strong. The first part of this volume comprises five articles mainly concerned with biomass resource potential and management. More specifically, the reported investigations assess grass and lawn substrates, rapeseed straw and microalgae from Upflow Anaerobic Sludge Blanket (UASB) reactor effluents as possible sources of biogas, bioethanol and biodiesel, respectively. The emphasis in the subsequent group of eleven articles is on biomass conversion processes, aiming at assessing performance as well as output quality and diversity. Biodiesel, a fluid biofuel produced from biomass with high lipids such as rapeseed oil, sunflowers and soy beans, is the focus of two articles: the first investigates the effect of biodiesel blending with diesel fuel on diesel engine performance and emissions, the second assesses the efficiency of catalytic reforming of biodiesel into a gaseous mixture, used directly as Solid Oxide Fuel Cell (SOFC) fuel. In the last three articles, the prospects of biofuels as viable sources of energy are examined within European contexts. This volume addresses a significant number of important themes and thus combines subject breadth and density with in-depth study of biomass resourcing and processing as well as the issue of biofuel and renewable energy sustainability.
