Abstract

This book examines the very current issue of wood waste treatment to a solid biofuel for energy recovery. The book is dedicated to research in the densification processes of wood waste and its mathematical description for uniaxial densification into compact biofuels – briquettes.This monograph, derived from an experimental research of densification process in laboratory conditions and also in real technologies in practice, provides a thorough understanding of the influencing parameters impact during densification of wood waste into solid biofuel. The book shows the experimental strategy to determine the effects of individual parameters and specifies their impact on the resulting density of the briquettes. The publication also defines the level of importance of the results in terms of optimization of the densification machine’s pressing chamber.Using a designed mathematical model, which was a result of experimental research and which can serve to predict the density of briquettes for some predefined densification conditions and can aid in the design of densification machines, the author has made this topic accessible beyond his discipline, biofuels producers and the academic community.

Abstract

ca. 200 words; this text will present the book in all promotional forms (e.g. flyers). Please describe the book in straightforward and consumer-friendly terms.The book gathers 28 quality papers containing new and important knowledge on forest operations, engineering and management. Active forest management is indeed applied through forest engineering, and careful forest tending is conditional to the implementation of sound operational methods, which may guarantee cost-effective management while protecting environmental functionality and worker health. Efficiently managed forest operations offer the highest benefit and the lowest cost, in all fields: financial, social and environmental. While maintaining a cross-disciplinary character, forest engineering represents a special sector of interest within the field of forestry and aims at increasing the overall efficiency of forest operations. Forest engineering often deals with practical issues that have a strong economic impact, and for this reason the industry has always had a strong interest in forest engineering, which explains the close connection between scientists and economic operators. The central role of forest engineering in modern forestry is demonstrated by the many sessions gathered under this general label at the IUFRO 125th Anniversary Congress, which offered a great opportunity for catching up with the latest results of sector research. Over the years, much progress has been done in the field of forest engineering, which has been supported by the dramatic technology advances of the most recent times. The 28 papers contained in this book come from many different countries and cover a large variety of subjects, from pure productivity, to resource availability, operation planning, environmental impacts and operator safety and health. Energy biomass is also represented, as a witness to the growing role of forestry in the quest for renewable energy sources.

Abstract

In the past 20 years protein engineering has been used for the production of proteins mostly for biological applications. The incorporation of artificial amino acids and chemical handles into proteins had made possible the design and production of protein-based materials like hybrid inorganic-organic materials, smart/ responsive materials, monodisperse polymers, and nanoscale assemblies. In the current topic, we cover current uses and envision future applications of materials generated using protein engineering and biosynthesis techniques.

Abstract

Value chains of bio-based chemicals are very complex. Hence, a strategic decision support tool for bioeconomic site and logistics planning is developed. It includes an integrated model and three sub-models: optimization for the locations and capacities of pretreatment plants, technical for technical and economic evaluations, risk for the evaluation of uncertainties. As a result, the model suggests a nearly optimal location and the associated logistic network for the production of biochemicals.

Abstract

The conversion of lignocellulosic biomass into renewable fuels and other commodities has provided an appealing alternative towards supplanting global dependence on fossil fuels. The suitability of multitudes of plants for deconstruction to useful precursor molecules and products is currently being evaluated. These studies have probed a variety of phenotypic traits, including cellulose, non-cellulosic polysaccharide, lignin, and lignin monomer composition, glucose and xylose production following enzymatic hydrolysis, and an assessment of lignin-carbohydrate and lignin-lignin linkages, to name a few. These quintessential traits can provide an assessment of biomass recalcitrance, enabling researchers to devise appropriate deconstruction strategies. Plants with high polysaccharide and lower lignin contents have been shown to breakdown to monomeric sugars more readily. Not all plants contain ideal proportions of the various cell wall constituents, however. The capabilities of biotechnology can alleviate this conundrum by tailoring the chemical composition of plants to be more favorable for conversion to sugars, fuels, etc. Increases in the total biomass yield, cellulose content, or conversion efficiency through, for example, a reduction in lignin content, are pathways being evaluated to genetically improve plants for use in manufacturing biofuels and bio-based chemicals. Although plants have been previously domesticated for food and fiber production, the collection of phenotypic traits prerequisite for biofuel production may necessitate new genetic breeding schemes. Given the plethora of potential plants available for exploration, rapid analytical methods are needed to more efficiently screen through the bulk of samples to hone in on which feedstocks contain the desired chemistry for subsequent conversion to valuable, renewable commodities. The standard methods for analyzing biomass and related intermediates and finished products are laborious, potentially toxic, and/or destructive. They may also necessitate a complex data analysis, significantly increasing the experimental time and add unwanted delays in process monitoring, where delays can incur in significant costs. Advances in thermochemical and spectroscopic techniques have enabled the screening of thousands of plants for different phenotypes, such as cell-wall cellulose, non-cellulosic polysaccharide, and lignin composition, lignin monomer composition, or monomeric sugar release. Some instrumental methods have been coupled with multivariate analysis, providing elegant chemometric predictive models enabling the accelerated identification of potential feedstocks. In addition to the use of high-throughput analytical methods for the characterization of feedstocks based on phenotypic metrics, rapid instrumental techniques have been developed for the real-time monitoring of diverse processes, such as the efficacy of a specific pretreatment strategy, or the formation of end products, such as biofuels and biomaterials. Real-time process monitoring techniques are needed for all stages of the feedstocks-to-biofuels conversion process in order to maximize efficiency and lower costs by monitoring and optimizing performance. These approaches allow researchers to adjust experimental conditions during, rather than at the conclusion, of a process, thereby decreasing overhead expenses. This Frontiers Research Topic explores options for the modification of biomass composition and the conversion of these feedstocks into to biofuels or biomaterials and the related innovations in methods for the analysis of the composition of plant biomass, and advances in assessing up- and downstream processes in real-time. Finally, a review of the computational models available for techno-economic modeling and lifecycle analysis will be presented.

Abstract

Biomass will play an important role in the future for the replacement of fossil sources for fuels and chemicals. Catalytic processes are required for the efficient conversion of biomass. The development of such processes and the understanding of the catalytic reactions of biomass molecules has recently attracted considerable and increasing attention. In this book, thirteen experts in different fields deliver their views on the state-of-the-art and future development of the use of biomass as a sustainable feedstock for the chemical industry. The book focuses on chemical aspects, such as catalyst development product analysis or reaction engineering, but also seeks a wider perspective and convers related issues like bioeconomics and plant growth.This book is aimed at students and scientists in the interdisciplinary field of catalysis for an introduction to the emerging field of biomass conversion and an overview on recent developments and challenges. The papers are based on lectures presented by the authors at a summer school organized by the Fritz-Haber-Institut and held in August 2010 at Kloster Seeon in Germany in the framework of the National Science Foundation-funded program Partnership in International Research and Education: Molecular Engineering for the Conversion of Biomass Derived Reactants to Fuels, Chemicals, and Materials.

Abstract

Algae biomass has enormous potential to produce fuels and value-added products. Algae-derived biofuels and bioproducts offer great promise in contributing to U.S. energy security and in mitigating the environmental concerns associated with conventional fuels. Algae’s ability to grow in low quality water/wastewater and to accumulate lipids has encouraged scientists to investigate algae as a medium for wastewater treatment and a potential source of fuel and bioproducts. There are growing demands for biomass-based transportation fuels, including biodiesel, bio-oil, biomethane, biohydrogen, and other high-value products (nutraceuticals, proteins, omega-3 etc.). Algae can help address these needs. The topic of algae energy includes the production and characterization of algae cultures, conversion into fuel feedstocks and high value products, and optimization of product isolation and use. In view of the increasing efforts in algae biomass production and conversion into energy and high-value products, the current research topic covers important aspects of algal strain selection, culture systems, inorganic carbon utilization, lipid metabolism and quality, biomass harvesting, extraction of lipids and proteins, and thermochemical conversion of algal feedstocks into biocrude.

Abstract

Grasses are diverse, spanning native prairies to high-yielding grain cropping systems. They are valued for their beauty and useful for soil stabilization, pollution mitigation, biofuel production, nutritional value, and forage quality; grasses encompass the most important grain crops in the world. There are thousands of distinct grass species and many have promiscuous hybridization patterns, blurring species boundaries. Resources for advancing the science and knowledgebase of individual grass species or their unique characteristics varies, often proportional to their perceived value to society. For many grasses, limited genetic information hinders research progress. Presented in this research topic is a brief snapshot of creative efforts to apply modern genomics research methodologies to the study of several minor grass species.
