Wood preservation is the process of treating wood to improve its durability, resistance to decay, and longevity. This is typically done by applying chemicals to the wood to protect it from fungi, insects, and other forms of deterioration. The goal of wood preservation is to extend the lifespan of wood products, reduce maintenance costs, and promote sustainability by minimizing the need for replacements. Research in this area focuses on developing new methods and technologies for wood preservation, testing the efficacy of different chemical treatments, and understanding the environmental impact of these processes.
