Wood plays an important role in the world economy. However, wood is subject to attack from wood-degrading fungi and insects and durability and quality of wood products are becoming increasing concerns for consumers. Development of effective and low environmental impact technologies to improve wood product quality and durability will be required to address these concerns. The application of a biological treatment to wood products is an example of one such technology. During the past fifteen years, a series of research projects were conducted at FPInnovations–Forintek Division to explore and develop various biological technologies and treatments to improve wood quality and durability against mold, stain and decay. These projects included 1) biological protection of logs and green lumber from mold, stain and decay; 2) biological pre-drying of wetwood lumber; 3) biological treatment to improve wood panel durability; 4) biological modification of wood to reduce resin use in panel manufacturing; and 5) biological incising to harden wood. This article summarizes the significant technical breakthroughs and findings made in these studies.
