Abstract

Faced with the escalating crisis of global deforestation, including particularly alarming rates in Sri Lanka, researchers have turned their attention to the potential of boronbased preservatives for treating timber. The comprehensive study of the samples has revealed a significant negative correlation between the treatability of timber under pressure and the total area of vessels and wood density. Woods with fewer and smaller vessels are more receptive to boron treatment, making them more suitable for preservation. The study also identified a positive, though somewhat weak, correlation between treatability and the total ray area within the wood, indicating that the internal structure of timber plays a crucial role in its preservation potential. The timber during the research has been categorized based on the depth of boron penetration, with categories ranging from fully penetrated to less than 5 mm. The findings obtained suggest that boron preservatives offer a promising and sustainable alternative to traditional timber treatment methods. By categorizing wood based on the treatability and anatomical properties, we can optimize the treatment processes, thereby maximizing resource utilization and minimizing waste. Thus boron-treated timber could become a cornerstone in the fight against deforestation in future, providing a responsible and environmentally friendly alternative to the untreated wood. In doing so, the research contributes significantly to the preservation of our forests and the overall well-being of our planet, offering a promising trajectory in sustainable forestry practices.
