Perennial Grasses for Bioenergy and Bioproducts


Book Description

Perennial Grasses for Bioenergy and Bioproducts: Production, Uses, Sustainability and Markets for Giant Reed, Miscanthus, Switchgrass, Reed Canary Grass and Bamboo brings together a team of international authors to explore the current utilization, sustainability and future perspectives of perennial grasses in the bioeconomy. The book begins by examining the role of these crops as feedstock for bioenergy, in particular advanced biofuels and bioproducts. It then offers five chapters, each covering one perennial grass type, namely giant reed, miscanthus, switchgrass, reed canary grass and bamboo. The book covers their breeding, cultivation, harvesting, pre-treatment, economics and characterization. The book goes on to present the thermochemical conversion pathways for different types of feedstock. The last chapter explores issues concerning sustainability of perennial grasses, including their production in marginal lands. This thorough overview is a helpful reference for engineering researchers and professionals in the bioenergy sector, whose understanding of feedstock characterization, sustainability and production is critical in the development of conversion technologies. Those in the industrial crops sector will benefit from discussion of various issues surrounding crop production, which can guide their feedstock cultivation, harvesting and pre-treatment for specific conversion processes or end use. The book is also a useful resource for instructors and students in Masters and PhD programs in the area of biomass and energy crops. Policy makers and government agents involved in regulating the bioenergy and bioproducts sector will find comprehensive information to guide their decision making. Explores the whole value chain of grassy feedstock for advanced biofuels and bioproducts, from cultivation to end use, including biomass characterization (physical properties, chemical composition, etc.) and conversion and sustainability Examines the sustainability and economic factors related to perennial grasses and their conversion into biofuels and bioproducts Includes a complete list of grasses relevant for energy uses, and tables with their current and expected future uses and markets




Perennial Biomass Crops for a Resource-Constrained World


Book Description

This book presents a flavour of activities focussed on the need for sustainably produced biomass to support European strategic objectives for the developing bioeconomy. The chapters cover five broad topic areas relating to the use of perennial biomass crops in Europe. These are: ‘Bioenergy Resources from Perennial Crops in Europe’, ‘European Regional Examples for the Use of Perennial Crops for Bioenergy’, ‘Genotypic Selection of Perennial Biomass Crops for Crop Improvement’, ‘Ecophysiology of Perennial Biomass Crops’ and ‘Examples of End-Use of Perennial Biomass Crops’. Two major issues relating to the future use of biomass energy are the identification of the most suitable second generation biomass crops and the need to utilise land not under intensive agricultural production, broadly referred to as ‘marginal land’. The two main categories of plants that fit these needs are perennial rhizomatous grasses and trees that can be coppiced. The overarching questions that are addressed in the book relate to the suitability of perennial crops for providing feedstocks for a European bioeconomy and the need to exploit environments for biomass crops which do not compete with food crops. Bioenergy is the subject of a wide range of national and European policy measures. New developments covered are, for example, the use of perennial grasses to produce protein for animal feed and concepts to use perennial biomass crops to mitigate carbon emissions through soil carbon sequestration. Several chapters also show how prudent selection of suitable genotypes and breeding are essential to develop high yielding and sustainable second generation biomass crops which are adapted to a wide range of unfavourable conditions like chilling and freezing, drought, flooding and salinity. The final chapters also emphasise the need to be kept an eye out for potential new end-uses of perennial biomass crops that will contribute further to the developing bioeconomy.




Bioenergy and Biomass from Industrial Crops on Marginal Lands


Book Description

Biomass from Industrial Crops on Marginal Lands provides a thorough overview of the value chain and available land for industrial crops, from field to use for energy and bioproducts. It discusses the role of industrial crops in the biobased economy, which industrial crops can be successfully grown on marginal or contaminated lands, and how much of that kind of land is available. The book categorizes these crops into four main groups: oilseeds, lignocellulosic, carbohydrate and specialty crops. It analyzes the most promising industrial crops to be grown on marginal lands per category, giving information from production to end use. The structure of these chapters allows for comparisons and better informed choices between different crops for specific industry requirements and land conditions. Finally, in its final chapter, phytomanagement of contaminated lands as an effect of growing industrial crops will be discussed.Bioenergy and Biomass from Industrial Crops on Marginal Lands gathers in a single volume information that has so far been scattered in the available scientific literature. Therefore, it is a valuable tool for the scientists and industry practitioners working in the area of biomass production, biofuels production and biorefining. Graduate students in master courses on industrial crops as source for value added products and bioenergy also benefit from this comprehensive reference. Content spans the entire value chain of various types of biomass derived from industrial crops, and their application in bioenergy and biorefining within the context of the bioeconomy Covers the challenges for sustainable management and production chains of industrial crops grown on marginal or contaminated land for use in bioenergy and biorefining Includes examples of field and lab experiments, and case-studies from field to fuel




Phytoremediation Potential of Perennial Grasses


Book Description

Phytoremediation Potential of Perennial Grasses provides readers with the knowledge to select specific perennial grass species according to site-specific needs. In addition, it demonstrates the potential opportunities for grass-based phytoremediation to yield phytoproducts, especially biomass-based bioenergy and aromatic essential oils as a green economy while in the process of remediating contaminated sites. The book brings together recent and established knowledge on different aspects of grass-based phytoremediation, providing this information in a single source that offers a cutting-edge synthesis of scientific and experiential knowledge on polluted site restoration that is useful for both practitioners and scientists in environmental science and ecology. Provides a holistic approach to grass-based phytoremediation, covering the ecological, economic and social issues related to its management Addresses the key role that grass-based phytoremediation plays in maintaining ecosystem services in polluted sites Includes strategies to mitigate costs related to the phytoremediation of polluted sites

Environmental Enhancement Using Short-rotation Woody Crops and Perennial Grasses as Alternative Agricultural Crops


Book Description

Short-rotation woody crops and perennial grasses are grown as biomass feedstocks for energy and fiber. When replacing traditional row crops on similar lands, these alternative crops can provide multiple environmental benefits in addition to enhancing rural economies and providing valuable resources. The DOE is supporting research to address how these crops can provide environmental benefits to soil, water, and native wildlife species in addition to providing bioenergy feedstocks. Research is underway to address the potential for biomass crops to provide soils conservation and water quality improvements in crop settings. Replacement of traditional erosive row drops with biomass crops on marginal lands and establishment of biomass plantations as filter strips adjacent to streams and wetlands are being studied. The habitat value of different crops for wildlife species is also considered. Combining findings on wildlife use of individual plantations with information on the cumulative effects of multiple plantations on wildlife populations can provide guidance for establishing and managing biomass crops to enhance biodiversity while providing feedstocks. Data from site-specific environmental studies can provide input for evaluation of the effects of large-scale plantings at both landscape and regional levels of resolution.
