Book Description
British Columbia has a large wood veneer products industry, producing predominantly plywood and laminated-veneer lumber (LVL). However, the damage done by the mountain pine beetle (Dendroctonus ponderosae, MPB) infestation has reduced material recovery and made the British Columbia plywood mills lose market share and mill profit. This project investigated the technical feasibility and economic benefits of using phenol formaldehyde resins to treat mountain pine beetle-attacked lodgepole pine (Pinus contorta Dougl.) veneers and to produce high-performance, durable engineered wood products.--Document.

Book Description
Wood is a gift from nature. It is a sustainable and renewable bio-composite material that possesses a natural ability to mitigate carbon dioxide. However, due to deforestation and climate change, it has become necessary to develop alternative building and construction materials. Engineered wood products (EWPs) such as parallel strand lumber, laminated veneer lumber, and cross-laminated timber are promising substitutions for conventional lumber products. This book presents a comprehensive overview of EWPs, including information on their classification, design, synthesis, properties, and more. It is divided into two sections: “General Overviews and Applications of EWPs” and “Recent Research and Development of EWPs”. The book is a valuable reference for manufacturers, engineers, architects, builders, researchers, and students in the field of construction.

Book Description
"When mountain pine beetle logs are used to manufacture plywood and laminated-veneer lumber, veneer recovery can drop by 30%. Veneer composing is an effective and efficient way to improve veneer recovery, and the lower moisture content of mountain pine beetle veneers makes composing green veneers feasible and advantageous. This project studied the feasibility of composing green mountain pine beetle veneers using three gluing methods: taping, string-gluing, and fibre-gluing."--Document.

Book Description
This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle (MPB) epidemic. This project quantified the impact of key parameters during plywood manufacturing on glue dry-out and bond quality using MPB veneers. The objectives of the study were to investigate the effect of key manufacturing parameters on glue dry-out and delamination of MPB plywood and to develop a manufacturing strategy to minimize glue dry-out and delamination in MPB plywood production.--Includes text from document.

Book Description
This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. This document reports on a project conducted to determine the impact of using mountain pine beetle (MPB)-attacked wood on plywood manufacturing processes and to implement the optimum processing parameters in mill production in order to increase value recovery and productivity. The specific objectives of the project were to investigate and quantify the effect of beetle-wood veneer on veneer visual and stress grading; the efffect of beetle-wood veneer on gluing, panel lay-up and gluebond performance; the effect of beetle-wood veneer on the plywood hot pressing process and resulting panel quality, stiffness, and strength; and the costs and benefits of adjusting manufacturing processes in a mill trial that transfers the technology.--Includes text from document.

Book Description
This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.

Book Description
Oriented strand board (OSB) accounts for a large share of the market for sheathing and sub-floor underlay, but because of its lower dimensional stability when exposed to moisture, it has not completely replaced plywood. The manufacture of OSB represents one of the major ways in which value can be recovered from mountain pine beetle-killed wood. This paper investigates a range of different coating and water-repellent technologies to reduce moisture absorption and thickness swelling of OSB made from mountain pine beetle wood.--Document.
