Fungal decay in cable car pylons in Svalbard - overview of results
2025 - IRG/WP 25-41026
A total of 212 iconic wooden cable car pylons were constructed for mining operations in Svalbard, significantly contributing to Longyearbyen's historical identity as a mining town. Fieldwork in Svalbard involved collecting wood samples from 22 of these pylons, targeting wood exposed both aboveground and ground proximity. Whilst the timber used in the constructions was assumed to be untreated Norwa...

Linking treatability with moisture dynamics
2025 - IRG/WP 25-41031
Wood preservation is inherently linked to the ability to penetrate treating liquids. The EN 147374 (2022) standard provides a methodology to assess treatability and allows to identify wood species in relation to treatability classes. Over the past decades, performance of wood species in applications in use class 3 has been linked both to the impact of moisture dynamics and the resistance against f...

Colorimetric performance of temperate wood species under tropical weathering
2025 - IRG/WP 25-41041
The appearance of wood, including its color and texture, is one of the most important features for its application as solid products, such as furniture, cladding, and terrace decking. Weathering can cause significant changes in the color of wooden products in outdoor applications, influencing their market acceptance and long-term performance. This study evaluated the colorimetric performance of fo...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...
