In the agriculture, forestry, the primary and secondary wood working industry there are considerable resources of raw materials which can only be used in a rational manner for energetic purposes. Due to requirements from the users. one of the most retinal way of utilization is to make pellets with high density and specific energy content. Making pellets of 6-8 mm diameter, their utilization in furnaces allows an almost fully automated operation with high thermal efficiency. This book describes both the theoretical and practical aspects of pellet production including material requirements and preparation, pressing technologies, quality requirements, burning properties, investments and the overall economy of pellet production.

This book comprehensively summarizes important aspects of research in the active field of lignocellulosic (polymer) composites, including polymer materials from or containing cellulose, hemicellulose and lignin. It describes how these materials can be produced from forest products and natural fibers from sources such as jute, flax, sisal, and many more, and even from agricultural residues (like wheat straw, corn stover, or sugarcane bagasse). In times of high demand for renewable green materials, lignocellulosic materials from organic matter produced by trees, shrubs and agricultural crops present a highly attractive feedstock. The international authors explain different treatment and fabrication methods for the production of lignocellulosic materials. Other chapters address the properties of these green materials or illustrate specific applications, ranging from food packaging and household products to adsorbents and even conductive polymer composites. In this way, this book offers a broad and comprehensive overview over the entire field of lignocellulosic composite materials.

This study examines the process of capital accumulation at the level of the business firm, linking it to the macro-level of the world-economy as explicated by Hopkins and Wallerstein. Focusing upon the timber industry in the nineteenth century, and using primary archival material, the work analyzes how capital operates in the resource sector in the world-economy. The purpose is to refine further our understanding of capitalism as a mode of social organization and production, and in the process, refine contemporary theories of social change. In terms of coverage, the book addresses the timber industry over the course of the nineteenth century and provides an historical reconstruction of that industry. Its primary focus, however, is on the main features of timber and lumber production as a process of capital accumulation. The study will be of interest to scholars of social change and economic transformation, economic history, and political sociology.

This book covers both basic and applied sciences in a rather specified area of pulp and paper manufacture. The basic science of lignocellulose enzymology and plant genetics is covered also in many other contexts, whereas the application of biotechnology in process and product development is thoroughly reviewed. All the latest advances as well as new ideas of the research field are covered. This book will serve as an updated and compact information package of biotechnical aspects and the most recent advances of the pulp and paper industry sector.

The volume is intended as a basic introduction to the history of papermaking technology, and it is aimed at students and teachers as course material and as a handbook for professionals working in either industry, research centres or universities. It caters to graduate audiences in forestry, business, technical sciences, and history.

Pulp and paper mill industries are always associated with the disposal problem of highly contaminated sludge or bio-solids. The development of innovative systems to maximize recovery of useful materials and/or energy in a sustainable way has become necessary. The management of wastes, in particular of industrial waste, in an economically and environmentally acceptable manner is one of the most critical issues facing modern industry, mainly due to the increased difficulties in properly locating disposal works and complying with even more stringent environmental quality requirements imposed by legislation. This book presents a general Introduction on waste management in the pulp and paper industry and contains topics on the generation of waste in pulp and paper mills, waste composition, methods of sludge pre-treatment, processes and technologies for conversion of pulp and paper mill waste into valuable products, waste reduction techniques employed in the pulp and paper Industry worldwide and future trends.

This monograph describes ways of using trees and their byproducts in environmental protection technologies and methodologies throughout their lifecycles. The tree, the planet's main source of biomass, is an indispensable tool for sustainable technologies, and the authors present a holistic picture of how and why in this volume. The authors describe the indispensable role of the living tree in phytoremediation and biomonitoring and detail the relationship of the tree with its surrounding ecosystem. The direct and indirect relationships of a tree at its vegetation period with various components of the ecosystem (i.e. atmosphere, hydrosphere, lithosphere and soil) contribute to the role of a tree as the medium for integrating aerogenic and edaphic pollutants. Trees phytostabilize pollutants in their organisms and remove them from the soil. The ability of some species of trees to reflect the quality of the environment makes a basis for the environmental bioindication, while quantitative representation of the chemical composition of the surrounding environment allows for the use of trees in biomonitoring. Morphological features of trees (e.g. annual tree rings) allow us to observe environmental conditions in the past and retrospectively evaluate them. This monograph also details how wood products (e.g. biochar, chips, bark, etc.) of a tree after it has died are used in environmental technologies. Due to the specific morphological form and physical and chemical composition of wood products, they may be used as active materials in the technologies aimed at reducing pollution in an effective and sustainable manner.

With today's ever growing economic and ecological problems, wood as a raw material takes on increasing significance as the most important renewable source of energy and as industrial feedstock for numerous products. Its chemical and anatomical structure and the excellent properties that result allow wood to be processed into the most diverse products; from logs to furniture and veneers, and from wood chippings to wooden composites and paper. The aim of this book is to review advances in research on the cellular aspects of cambial growth and wood formation in trees over recent decades. The book is divided into two major parts. The first part covers the basic process of wood biosynthesis, focusing on five major steps that are involved in this process: cell division, cell expansion, secondary cell wall formation, programmed cell death and heartwood formation. The second part of the book deals with the regulation of wood formation by endogenous and exogenous factors. On the endogenous level the emphasis is placed on two aspects: control of wood formation by phytohormones and by molecular mechanisms. Apart from endogenous factors, various exogenous effects (such as climate factors) are involved in wood formation. Due to modern microscopic as well as molecular techniques, the understanding of wood formation has progressed significantly over the last decade. Emphasizing the cellular aspects, this book first gives an overview of the basic process of wood formation, before it focuses on factors involved in the regulation of this process.

Pulp and paper production has increased globally and will continue to increase in the near future. Approximately 155 million tons of wood pulp is produced worldwide and about 260 million is projected for 2010. To cope with the increasing demand, an increase in production and improved environmental performance is needed as the industry is under constant pressure to reduce environmental emissions to air and water. This book gives updated information on environmentally benign approaches for pulp bleaching, which can help solve the problems associated with conventional bleaching technologies.
Main focus is on the environmentally-friendly technologies that can help solve some of the problems associated with conventional bleaching technologiesInformation given is up-to-date, authoritative, and cites the experiences of many mills and pertinent research, which is of interest to those working in the industry or intending to do soCovers in great depth all the aspects of various bleaching processes including environmental issues
