Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.

This book is primarily a general text covering the whole sweep of the forest industries. The over-riding emphasis is on a clear, simple interpretation of the underlying science, demonstrating how such principles apply to processing operations. The book considers the broad question "what is wood?" by looking at the biology, chemistry and physics of wood structure. Wood quality is examined, and explanations are offered on how and why wood quality varies and the implications for processing. Finally, various "industrial processes" are reviewed and interpreted. All chapters have been written by specialists, but the presentation targets a generalist audience.

Since the sixth edition of this classic text/reference was published in 1981, there have been so many developments in the field that the new seventh edition represents an almost total rewrite of the subject matter. The opportunity has been taken to rearrange the structure and broaden the scope to cover areas of conversion, machining and the application of paints and finishes; the format has also been enlarged to improve readability. Part 1 contains chapters that deal with the structure of wood at the gross, cellular and molecular levels; variability is also covered. Part 2 has five chapters on the properties of wood, with special coverage of elastic behaviour, toughness and the use of structural-sized timber for strength tests. Part 3 on processing has material on several new areas not covered in earlier editions of the book; for example, log conversion, seasoning, and the machining of wood and board. The discussion of grading and grade stresses is fully updated. Part 4 on utilisation examines the latest techniques and standards for the manufacture of wood products. Part 5 examines all aspects of timber in service, including protection and preservation. The book will appeal to a wide readership, both as a student text and reference. Students of wood science and forestry at undergraduate and equivalent level will find it of special value. All institutions with courses in the built environment will wish to make the book available as a reference source.

73 articles, newly commissioned or revised from the acclaimed Encyclopedia of Materials Science & Engineering, cover the whole range of knowledge and current research in wood science. Topics discussed include the availability of economics and timber resources, wood products such as plywood and mineral-bonded wood composites, the major commercial and wood species of the world, fundamentals of wood properties and behavior, factors causing deterioration and their control and principal processing methods. Recent developments in the use of acoustic emission techniques and biotechnology in wood processing are dealt with and the range of materials covered includes woody materials such as bamboo, coconut wood and rattan, not hitherto treated by any similar publication. Extensively illustrated, with nearly 200 photographs, drawings and tables in over 300 pages, each article is intended to serve as the primary source of information on a given topic. The reader is guided to further reading by helpful cross-references and nearly 500 up-to-date citations in the bibliographies at the end of each article. A comprehensive, three-level subject index is also provided. The Concise Encyclopedia of Wood & Wood-Based Materials will be invaluable to architects, engineers, builders, plant managers, wood technologists, purchasing agents, politicians, timber merchants, and furniture manufacturers.

Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.

This book offers a broad range of options for technically adapting, handling and processing wood with specific wood characteristics. It starts by discussing wood anatomy and the general factors leading to the formation of wood characteristics. The individual characteristics are then categorized into four groups: 1. Wood characteristics inherent in a tree’s natural growth. 2. Biotically-induced wood characteristics. 3. Abiotically-induced wood characteristics. 4. Types and causes of cracks. New to this English edition is a comparison of wood characteristics found in trees from the boreal, temperate and tropical climate zones. The results show a clear relationship between the effects of sunshine duration, the vertical and horizontal angle of radiation, and crown coverage and the way wood characteristics form. The book addresses all those who work with wood professionally: foresters, gardeners and arborists who want to be able to observe a living tree and identify its internal features and the causes of its prominent wood characteristics. Based on the findings described in this book they can determine how to avoid certain undesirable characteristics, or alternatively how to promote favorable ones as the tree and stand grow. Botanists and dendrologists will learn how wood characteristics arise, and how they affect living trees and wood products. The needs of wood technologists seeking to prevent adverse wood characteristics from influencing wood processing, or to enhance favorable wood characteristics, are also addressed.
