This atlas presents macroscopic descriptions, macro cross section pictures, general characteristics and identification keys of 335 wood species currently introduced in the European timber market from all over the world. Overall 292 different genera are represented and CITES-listed timbers are also included. Macroscopic descriptions are based on a recently proposed list of macroscopic features for wood identification. Macroscopic features and their codes are defined and illustrated in the atlas. Wood descriptions also include information about natural durability, physical and mechanical properties, end uses, environmental sustainability and possible related misleading commercial names. Furthermore, each genus is described in terms of number of species, geographical distribution and main commercial timbers, and details are given about to what extent timbers within the genus can be typically identified through macroscopic and microscopic analysis, if any. The atlas will be a valuable guide for all agents in charge for timber verification, those involved in the European Timber Regulation enforcement and CITES inspections, as well as wood scientists, foresters, wood sellers, wood restorers, and any wood worker and wood passionate interested in a fast and reliable tool for wood identification.
Large numbers of tropical trees from natural forests or plantation forest are available for human consumption and management. This book focuses on the prospects and utilization of tropical plantation trees in context of economic and business, planting, managing stocks, and uses of trees converted to various wood-based products. It provides information on key areas of tropical plantation trees including growth performance, nursery practices, soil properties, planting stock production, raw material cellulose, anatomy, pulping and papermaking, fiber modification, and properties of wood composites. Features: Comprehensive information on prospects and utilization of tropical plantation tree species. Features information on potential products derived from tropical plantation trees including cellulose-based wood products, particleboard with bioplastic binder, and laminated veneer lumber. Discusses species usage of economic importance other than wood production. Presents information on nursery practices, growth performance, and soil properties of tropical trees. Illustrates methodologies for repeating investigations on work that has been done previously in tropical tree research. This book introduces information for entrepreneurs or researchers before undertaking work with these tree species illustrating technical methodologies allowing for repetition or previous successful works. This information proves valuable to researchers if further work is needed for improvement on these plant-derived products.
Wood has played a major role throughout human history. Strong and versatile, the earliest humans used wood to make shelters, cook food, construct tools, build boats, and make weapons. Recently, scientists, politicians, and economists have renewed their interest in wood because of its unique properties, aesthetics, availability, abundance, and perhaps most important of all, its renewability. However, wood will not reach its highest use potential until we fully describe it, understand the mechanisms that control its performance properties, and, finally, are able to manipulate those properties to give us the desired performance we seek. The Handbook of Wood Chemistry and Wood Composites analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood. They emphasize the mechanisms of reaction involved and resulting changes in performance properties including modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating decades of teaching experience, the editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.
