Sävar has used a CT scanner for eight years, but it is now being relocated to the new log sorting facility so it can be fully utilized. As soon as logs arrive, the scanner identifies knots, cracks, and areas of dense fiber. Each log receives its own ID – almost like a fingerprint – making every log an individual with its own optimized purpose and value.
“We can decide exactly how each log should be sawn to produce the right products. The value optimization is absolutely outstanding,” says Samuelsson.
SEK 400 Million in Investments
The new technology is part of Norra Timber’s SEK 400 million investment program, which includes state-of-the-art CT scanners and log sorting systems at both Sävar and Kåge. The equipment has already been up and running in Kåge for about a year.
“By scanning the logs immediately, we can sort them according to internal quality. If a customer wants planks completely free of knots, we can select those logs from the start,” Samuelsson explains.
What makes the Sävar project unique is the integration of the scanning system with the production line. After scanning, each individual log is recognized as it enters the sawing process. A new log rotator, installed just before the saw line, positions the log exactly as the CT scan has predetermined.
The secret lies in measurement and control. Hypermodern technology ensures the optimal use of each log, and checkpoints verify that the process runs as planned. The benefits are clear: reduced waste, higher product quality, and more tailored solutions for customers.
“This makes us more competitive, but it’s also about responsibility. We use the raw material more efficiently and can show both customers and forest owners exactly how the wood is being used,” says Samuelsson.
Installation is currently underway, and the entire system will be operational in autumn 2025.
