New research from Karlstad University shows that fast-growing spruce trees can have longer fibers than expected, even at a relatively young age (around 40 years).
These fibers – important for bonding and material strength – suggest that the wood could be used for more applications and with higher structural capacity than previously believed.
Traditionally, slow-growing trees have been considered to produce stronger and higher-quality wood. However, this study challenges that assumption: if fast-growing spruce can deliver comparable quality, forestry could be conducted more efficiently with shorter rotation periods.
Researchers measured fiber lengths of 5–6 mm in these young trees — values that open up possibilities for stronger materials in construction and industry. At the same time, faster growth could help forests absorb more carbon, supporting climate goals.
We’re proud that Mikael Perstorper from LIMAB is part of this important research, contributing his expertise in wood measurement and quality analysis.
The study notes that the findings come from a specific region with unique geological conditions, and more research is needed to determine if the results apply across Sweden.
