Is cascading of harvested wood products really an environmentally beneficial strategy in Finland and Norway?
2020 - IRG/WP 20-50364
The role of cascading wood waste in the bioeconomy is highlighted in the several strategic documents. The European Waste Framework Directive describes a waste hierarchy where re-use and recovery are considered more favourable options compared with energy recovery, and applies strict re-use and recycling targets to household waste and non-hazardous construction and demolition waste. It is not fully...

Introduction to the project ‘Deterioration and decay of wooden cultural heritage in Arctic and Alpine environments’ (ArcticAlpineDecay)
2022 - IRG/WP 22-10997
The Arctic is already affected by climate change, and this is expected to accelerate over the coming decades. Alpine regions in Norway are projected to face similar challenges. Current knowledge on Norwegian wooden cultural heritage in Arctic and Alpine regions is scattered and contains significant knowledge gaps. Historically, - scientists, sectorial governance, tourist trade and commerce have ma...

Field durability testing of wood above ground - Part 1: 15 years’ experience with the Bundle method
2023 - IRG/WP 23-20695
A ‘jack of all trades’ method for above-ground wood durability testing has been sought for decades, but until now no method has found its way into standardization. The method of choice shall be applicable for untreated and treated wood – ideally also for wood composites. It shall be reproducible, objective, fast, easy, and inexpensive. Finally, it shall provide high predictive power.
This s...

Field durability testing of wood above ground - Part 2: The full guideline of the Bundle method
2023 - IRG/WP 23-20696
To determine the biological durability of wood above ground, numerous approaches for test methods have been pursued and tried out in the field in the past. So far, no method has managed to find its way into a European standard. During the last 15 years, experience with the Bundle method has been gained. As described in Part 1 of this paper, the method is recommended as a suitable tool for determin...

Utilising novel service life prediction methods for robust and precise Life-Cycle-Costing (LCC)
2023 - IRG/WP 23-50384
Life-Cycle-Costing (LCC) is one of the basic indicators for the assessment of sustainability and cost effectiveness in construction applications. Project WoodLCC was thus conceived to enable LCC through input from models for detailed service life planning of wooden components and buildings. The project is a continuation of the service life planning research conducted in Europe over the last three ...

Characterisation of fungal decay in cable car trestles in Svalbard
2023 - IRG/WP 23-11031
The Arctic will be strongly affected by climate change. In Svalbard the coal mining industry were established in the early 20th century. All man-made structures and sites dating before 1946 in Svalbard are protected by law and considered as cultural heritage. This included the massive cable car trestles that are constructed from untreated Norway spruce and mounted directly into the soil. We hereby...
