This article reviews the types of adhesive systems that are currently being used and that are under development for wood composites. These newer adhesives are generally considered to be more environmentally-friendly and lead to greater sustainability. The article will also discuss the related requirements of common types of wood composites and the processes that are used to manufacture these innovative materials. Wood composites are products derived by bonding together smaller pieces of timber products, such as strands, particles, fibers, or veneers. They are also sometimes referred to as engineered wood or manufactured board. These products are manufactured to meet national or international standards. They are used in a variety of structural and nonstructural applications similar to solid wood products. Plywood is considered to be the original wood composite, but many other types of materials have developed over the years.
