Analysis and performance of spruce alternative species and discarded wood for windows production
2024 - IRG/WP 24-50386
Climate change is having a significant impact on European forestry, particularly on the softwood species used for window frames. This study investigates potential replacement tree species for spruce (Picea abies), the predominant material for window frames. We evaluate Douglas fir (Pseudotsuga menziesii), Scots pine (Pinus sylvestris), thermally modified poplar (Populus nigra) and discarded silver...

Are we barking up the right tree? - the use of bark residues in wood protection
2025 - IRG/WP 25-20742
Tree bark, a lignocellulosic side-stream, is typically underutilised, often combusted or landfilled, thus contributing to greenhouse gas emissions. This communication paper explores the potential of bark residues, particularly suberinic acid, tannins and other polyphenols, in wood protection applications, including coatings, adhesives, and fire retardants. Several European projects have been initi...

CIOL Wood - Scientific Innovations in Wood Modification for Enhanced Performance and Usage
2025 - IRG/WP 25-20743
CIOL® is a wood modification technology designed as an environmentally friendly alternative to traditional wood preservatives. Utilising a biobased formulation based on sorbitol and citric acid, CIOL® enhances wood's chemical structure, improving its durability, stability, and resistance to decay. This paper provides an overview of the advancements made in CIOL® technology, including its improv...

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...
