Environmental Benefits of Wood Preservation
2023 - IRG/WP 23-50377
Over the past decade or two, many people have become significantly more aware and concerned about the global environment and the health of our planet. Building with wood products from sustainably managed forests carries significant environmental benefits. The ability of a growing tree to absorb carbon dioxide (CO2) and sequester the carbon is beneficial in the role of combating rising CO2 levels...

Fungicidal properties of black liquor from the waste MDF board digestion in terms of wood protection
2023 - IRG/WP 23-50379
The aim of the work was to determine the fungicidal properties of black liquor as a product of the chemical digestion of waste MDF board. The resistance of wood treated with black liquor from MDF waste pulping process was compared with the resistance of wood treated with black liquor from the pulping process of a by-product from agricultural production. The control material consisted of non-treate...

Towards a microactuator-sensing network for the structural health monitoring of wood
2023 - IRG/WP 23-50380
Timber structures decay over time with degradation in their structural integrity. Changing environmental conditions, varying loads, exposure to moisture or insect attacks lead to changes in their vibrational response behaviour. Here we present a low-cost device used as a triggered exciter to enable the monitoring of the structural integrity of timber bearers or even power poles in electricity netw...

Manipulation of the hierarchical wood structure for extended carbon storage in the built environment
2023 - IRG/WP 23-50381
The sustainable processing of trees into construction materials can act as carbon storage. Carbon storage in durable sustainable wooden construction material has cumulative effects and net gain in storage in the built environment that can be offset by net losses in forest carbon by cutting the tree. Carbon storage for an extended period plays an important role in the mitigation of CO2 emissions an...

Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

Assessment of the condition of wooden mill in the area of Kovačevići in Bosnia and Herzegovina
2023 - IRG/WP 23-11030
An excellent example of cultural and technical heritage is almost 100 year old wooden mills near Cazin in Bosnia and Herzegovina. These mills played an important role, especially in times of Bosnian war (1992-95), when this region was cut off from electricity. The laboratory analysis revealed that the respective mill was made of chestnut (Castanea sativa) and oak (Quercus sp.) wood. The sufficient...

Research on gaseous COS degradation by brown-rot fungus Gloeophyllum trabeum
2024 - IRG/WP 24-11033
Physiological studies of wood rotting fungi have mostly focused on the metabolism of carbon and nitrogen sources, which constitute the dominants components of wood. On the other hand, despite the physiological importance of trace elements such as sulfur, studies on their acquisition sources and metabolic pathways are limited. Until now, wood rotting fungi have been thought to utilize slight amount...

Cellulose nanomaterials in growth media for wood decay fungi
2024 - IRG/WP 24-11035
Cellulose nanofibrils (CNFs) were investigated as a partial substitution for agar in growth media for wood decay fungi. Radial growth measurements of eight basidiomycete fungi were taken on solid growth media with and without CNFs. Additionally, fungal strain virulence was evaluated using the European CSN Standard EN 113-2 wood decay durability test. The inclusion of CNFs did not significantly aff...

Protocol of action in urban areas affected by subterranean termite attacks in Spain. Example of management in the old town of Areatza
2024 - IRG/WP 24-11037
Termites are wood destroying insects always present in the nature with an important wood decomposition function. In Europe are located in the Mediterranean area. In Spain termites are an important problem in urban areas. It is estimated about 80% of old historic towns in Spain are affected by subterranean termite attacks and it is the most important damage in wood structures and wood elements. The...

Intra-species variability of moisture dynamics in wood
2024 - IRG/WP 24-11040
Moisture dynamics of wood and wood-based materials play a major role in wood durability against different decay organisms. Their impact becomes particularly evident when wood is exposed, but not permanently wet. To date, however, this has only been taken into account indirectly and therefore inadequately when testing the durability of wood. While test methods are available, for example to determin...

A novel cellulose-binding domain from the brown-rot fungus that can be used to evaluate cellulose in wood
2024 - IRG/WP 24-11046
Wood-rotting basidiomycetes are the primary microorganisms that decay wood in nature. They are classified as white-rot fungi and brown-rot fungi by the difference in decaying types. White-rot fungi secrete a variety of cellulolytic enzymes during wood degradation. These enzymes often have an additional cellulose-binding domain (CBD) that adsorbs to the cellulose surface and localizes the catalytic...

Suberinic acid from birch bark and its suitability in wood protection
2024 - IRG/WP 24-20708
This study investigated the effect of different concentrations of suberinic acid (SA) on the growth of two fungi species. Initial radial growth tests showed a slightly slower growth rate for brown rot, whereas white rot exhibited faster growth than the untreated reference. In contrast, a commercial wood preservative significantly reduced the radial growth of both fungi species. Evidence of cell wa...
