Wood plays a major role for the Norwegian Public Roads Administration (NPRA) in design and construction of modern bridges. The Norwegian design code demands a service life of 100 years; this poses a challenge independent of the material used. In case of wood, NPRA regards the creosote treatment as...

The forest-based sectors are in a period of significant transition due to climate change mitigation efforts, changes in forest products demand and other external mega-trends. This study applies a three-step Delphi process to identify the main drivers and formulate possible scenarios for the...

Planting new forests has received scientific and political attention as a measure to mitigate climate change. Large, new forests have been planted in places like China and Ethiopia and, over time, a billion hectares could become available globally for planting new forests. Sustainable management of ...

This paper presents an optimization model designed to find productivity functions for timber forwarding. Timber forwarding or skidding has for some 25 years been calculated using shortest path formulations on grid networks. Unfortunately, few productivity studies relate to such grids. Here, an...

Laboratory studies have shown that wood has hygroscopic properties. When used as a construction material in buildings, it can thus influence indoor relative humidity and temperature. Ventilation can affect indoor climate if the temperature differ between indoor and outdoor air. The coating of...

Many building users prefer wood over other building materials, but it is unclear how modified wood is perceived compared with unmodified wood. Additionally, it is unclear which material properties play a role in the general preference for wood, how tactile and tactile-visual perceptions of...

Forestry and forest industries are important for regional income and employment in Norway as well as in most North European countries, but few studies exist about factors affecting the timber supply at regional level. The main objective of this study is to estimate aggregated regional timber supply ...

The wood rot decay of structures and buildings in Norway represents high costs. This paper reports the observed trends for the potential rot decay of Norwegian wood structures in the cities of Oslo and Bergen over the recent 55 years, calculated as the "wood rot climate index" developed by...

This paper investigates the effects of the glue line, moisture content, and temperature on diffusion coefficients of engineered wood products. The diffusion coefficient were measured in three orthogonal directions for glued laminated timber (Glulam) made of Blackbutt (Eucalyptus pilularis), Pacific ...

Forest harvest residue is a low-competitive biomass feedstock that is usually left to decay on site after forestry operations. Its removal and pyrolytic conversion to biochar is seen as an opportunity to reduce terrestrial CO₂ emissions and mitigate climate change. The mitigation effect of biochar...
