One of SM2‘s main objectives is to provide sawmills with opportunities to diversify their production into new products and markets. In this regard, a group of researchers has obtained very interesting preliminary results within the scope of a wood protection project.
This project aims to evaluate the potential of a borate treatment for protecting wood from fungal growth; it can be carried out simultaneously with the heat treatment (HT) required for wood export according to international standards. Borate is applied by injection during heat treatment of the wood and provides uniform distribution in the stack without increasing the duration of heat treatment.
The trials, still at a preliminary stage, have made it possible to demonstrate the effectiveness of the injection system and a significant penetration of the sapwood of the product (top photo), while increasing resistance to fungi (bottom photo). More comprehensive results will be reported later.
