The iTrussT project – Advancements in timber bridge design, preservation, and monitoring
2025 - IRG/WP 25-20751
The Norwegian research project iTrussT (2025–2028) aims to advance timber bridge design and unlock wood’s full potential as a sustainable solution for modern infrastructure. It addresses three critical challenges: First, fatigue testing of glued laminated timber lamellae will provide deeper insights into shear failure mechanisms, supporting the development of safer, more efficient structures a...

Chestnut tannin-furfurylic resins for wood preservation: influence of the proportion of tannins as a copolymer
2025 - IRG/WP 25-30816
Tannin, which is present in all plants, is the most abundant polyphenol globally and can be extracted using water or organic solvents such as acetone, ethanol and methanol. Tannins are classified into two categories: condensed tannins (catechin-based polymers) and hydrolysable tannins (sugar esters with galloyl units). Previous studies have demonstrated its potential as a raw material for modifyin...

Preservation conditions of wooden roofs of two historical churches in middle-Sweden
2025 - IRG/WP 25-41016
Assessment of biodegradation by the rot of shingles from the roofs of churches of Hammarby and Tångeråsa in mid-Sweden was done by studies with X-ray computer tomography. The study suggests that inner rot could be detected with CT, which was not always easily detected by visual inspection. In some cases, erosion from the weathered side was fairly large, but the inner wood part was found not to b...

Durability evaluation of outdoor-exposed CLT treated with various wood presevatives using CT scans
2025 - IRG/WP 25-41035
Methods for wood preservation treatment of large materials such as Cross Laminated Timber (CLT) are limited. It is unclear which wood preservation treatment methods can effectively protect CLT from rot risk. In this study, accelerated rot tests (fungus cellar test) of CLT treated with the solvent-borne wood preservative by non-pressure treatment, named ‘deep penetration treatment’, were conduc...

Considerations on how different preservation processing methods of logs would have different effects on wood structures
2025 - IRG/WP 25-41040
Azekura-zukuri style wood structures (hereinafter referred to as azekura-style structures) have been utilized in forest conservation projects in Japan as substitutes for concrete structures. We estimate that making use of thinned and small logs for azekura-style structures has positive impact on circular economy and carbon fixation and contributes to the biodiversity within their areas. In additio...

Bio-Based but Toxic? The Neglected Ecotoxicity of Leachates from Wood Preservatives—A mini-review
2025 - IRG/WP 25-50403
Bio-based Wood preservatives, derived from renewable biomass, are emerging as promising alternatives to traditional synthetic wood preservatives. Research groups all around the world are studying the development of bio-based – environmentally friendly – wood preservatives and their fixation to wood finding natural compounds with very promising wood preserving potential. However, there is a ver...
