Perspectivity of Producing Building Materials from Wood with Heart Rot

The perspectivity of processing of wood containing the heart rot in building materials is substantiated. The subject of the study is methods for processing of wood with heart rot. The shortage of hardwood and softwood demands to treat the unmerchantable wood. Most often, wood with heart rot is sawn for firewood and sold the population as fuel. Differentiated approach to the choice of the method for processing of wood with heart rot is the substantiation of the type of the obtained materials and products of various functional purposes depending on the size of heart rot. To ensure the competitiveness, products made of wood with heart rot must have higher performance characteristics in comparison with existing materials and products. Therefore, the methods of producing need to be connected with specific materials or products. Wood with heart rot of a diameter of up to 50 mm is the most appropriate to use for the production of rounded logs. For processing of wood with heart rot of diameter of 50–100 mm, the best method is a rotary cut of healthy wood for subsequent bonding of plywood products. From wood with heart rot of a diameter of 50 mm and more, square-edged sawn timber of small sizes (pallets) can be obtained.
