For decades, researchers have been working on methods to enable machine strength grading beginning at the round timber stage, instead of doing the grading only on the sawn timber. This would lead to an integrated process, by which raw material efficiency and product quality of construction timber production could be optimized throughout. The newest developments in scanning technology now offer the opportunity to create such an integrated process with the potential for implementation in the industrial. This is what we do in the research project READiStrength (funded by the ERA-NET Cofund Call "ForestValue – Innovating the forest-based bioeconomy"), including the most important European softwood species spruce, pine, fir and Douglas fir.
