A Handbook Of Bioenergy Crops

As the world's population is projected to reach 10 billion or more by 2100, devastating fossil fuel shortages loom in the future unless more renewable alternatives to energy are developed. Bioenergy, in the form of cellulosic biomass, starch, sugar, and oils from crop plants, has emerged as one of the cheaper, cleaner, and environmentally sustainab

This completely revised second edition includes new information on biomass in relation to climate change, new coverage of vital issues including the "food versus fuel" debate, and essential new information on "second generation" fuels and advances in conversion techniques. The book begins with a guide to biomass accumulation, harvesting, transportation and storage, as well as conversion technologies for biofuels. This is followed by an examination of the environmental impact and economic and social dimensions, including prospects for renewable energy. The book then goes on to cover all the main potential energy crops.

The volume on Industrial Crop Breeding will be part of the series, Handbook of Plant Breeding. This volume will focus on the emerging area of plant breeding for sustainable production of transportation fuels and bio based products using the current advances in the field. The book is scheduled to consist of a total number of 30 chapters divided into four sections. The sections will emphasize crops being considered for different challenge areas including oil crops for biodiesel; sugar, starch and cellulosic crops for biofuel; crops for bio products and issues and future prospects. A chapter introducing the first three sections will also be included. Outstanding scientists for each crop species are proposed as senior authors, who may invite co-authors to contribute part of a chapter to provide additional expertise or perspective. The proposed authors will represent various national and international institutions to get a more diverse view on the topic and somehow get a global view on the common issues that researchers on industrial crops are facing. The book will comprise primarily of specific issues, available germplasm, breeding techniques, and potential geographical areas of production pertaining to individual crops being considered for industrial uses. We hope to encourage the proposed authors of new crops to provide an estimate of the crop readiness for commercial development and discuss the limitations. This book will be will be of interest and envisioned to serve as an updated reference to researchers in both academic and industrial setting, to students and teachers of plant breeding and to policy makers who are looking for alternative solutions to dependency on imported petroleum products.

In its second volume, this book aims to link the academic research with development in the real world and provide a historical and institutional background that can enrich more formal research. The first section will include an assessment of the evolution and the state of the nascent second-generation biofuel as well as a perspective on the evolution of corn ethanol and sugarcane ethanol in Brazil. It will also include a historical and institutional background on the biofuel industry in Brazil that has global lessons, and later, provide a technical overview of major analytical tools used to assess the economic, land use and greenhouse gas implications of biofuel policies at a regional and global level. Additionally, the book analyzes the various drivers for land use change both at a micro-economic level and at a macro-economic level. It presents studies that apply regional and global economic models to examine the effects of biofuel policies in the US, EU and Brazil on regional and global land use, on food and fuel prices and greenhouse gas emissions. These papers illustrate the use of partial and general equilibrium modeling approaches to simulate the effects of various biofuel policies, and includes studies showing the effects of risk aversion, time preferences and liquidity constraints on farmers decision to grow energy crops for biofuel production. By presenting the tools of lifecycle analysis for assessing the direct greenhouse gas intensity of biofuels, this handbook investigates the types of indirect or market mediated effects that can offset or strengthen these direct effects. It will include tools to assess the direct and indirect effects of biofuel production on greenhouse gas emissions in the US and Brazil, and ultimately provide a comprehensive background to understand the state of biofuel in the present and how to analyze their implication.

Ethanol as an alternative fuel is receiving a lot of attention because it addresses concerns related to dwindling oil supplies, energy independence, and climate change. The majority of the ethanol in the US is produced from corn starch. With the US Department of Energy’s target that 30% of the fuel in the US is produced from renewable resources by 2030, the anticipated demand for corn starch will quickly exceed the current production of corn. This, plus the concern that less grain will become available for food and feed purposes, necessitates the use of other feedstocks for the production of ethanol. For the very same reasons, there is increasing research activity and growing interest in many other biomass crops. Genetic Improvement of Bio-Energy Crops focuses on the production of ethanol from lignocellulosic biomass, which includes corn stover, biomass from dedicated annual and perennial energy crops, and trees as well as a number of important biomass crops. The biomass is typically pretreated through thermochemical processing to make it more amenable to hydrolysis with cellulolytic enzymes. The enzymatic hydrolysis yields monomeric sugars that can be fermented to ethanol by micro-organisms. While much emphasis has been placed on the optimization of thermo-chemical pretreatment processes, production of more efficient hydrolytic enzymes, and the development of robust microbial strains, relatively little effort has been dedicated to the improvement of the biomass itself.

It also gives an historical perspective and introduces the ethical issues.

Providing comprehensive coverage on biofuel crop production and the technological, environmental and resource issues associated with a sustainable biofuel industry, this book is ideal for researchers and industry personnel. Beginning with an introduction to biofuels and the challenges they face, the book then includes detailed coverage on crops of current importance or with high future prospects, including sections on algae, sugar crops and grass, oil and forestry species. The chapters focus on the genetics, breeding, cultivation, harvesting and handling of each crop.
