Moisture content as a quality control parameter in thermally modified timber production
2017 - IRG/WP 17-20622
Quality assurance (QA) or factory production control (FPC) is necessary to ensure a proper production process. The requirements of QA/FPC can result from EN and national standards, quality assurance systems, or producer-specific rules.
TMT producers must ensure that the process was correct, and to ensure traceability of products. In addition to the electronic records, the material should be che...

On the natural durability of RED MERANTI for window frames as a function of gross density wood
2018 - IRG/WP 18-10927
MERANTI is a wood species belonging to the family Dipterocarpaceae, in the genus SHOREA (Shorea spp.). The genus has approximately 196 species with four subgenera. The subgenus RUBROSHOREA is commonly named RED MERANTI (RM) and is found on the Malayan Island of Sarawak, Indonesia, with approximately 65 varieties (Symington 1943). According to Brazier (1956), the distribution of gross densities wi...

Exploring the use of X-ray micro CT as a tool for the monitoring of moisture production and mass loss during lab-based fungal degradation testing
2019 - IRG/WP 19-20654
Bio-based building materials, such as wood and wood-engineered products, are susceptible to degradation by decay fungi. In-depth knowledge on the intricate material-fungus relationship as well as performance data for many bio-based building materials are still lacking, and especially knowledge on how a material’s structure and moisture properties affect the degradation process is missing. Althou...

Pigment production by the spalting fungus Scytalidium ganodermophthorum and its industry potential
2020 - IRG/WP 20-10957
Scytalidium ganodermophthorum is best known as a pathogen of cultivated mushrooms, with infected cultures turning yellow in color. The fungus is also used in the art form known as ‘spalting’ to produce yellow, green, and purple colors in wood for decorative purposes. Wood colored by fungus in this manner has been traditionally used in the creation of fine art and woodworking since the 16th cen...

Aiming for eco-friendly log production and wooden construction!
2021 - IRG/WP 21-50365
In order to reduce greenhouse gas (GHG) emissions to zero by 2050 in the fields of forest and forest products, it is necessary to promote appropriate management and renewal of planted forests, and development of wooden building materials and the wooden construction of mid-to-high-rise buildings with lower GHG emissions. Unless we also try to reduce the environmental loads other than GHG for such d...

In Vitro Growth of the Basidiomycetes Physisporinus vitreus strains in various conditions in comparison with some white rot fungi
2022 - IRG/WP 22-10987
The paper has preliminary test results to select Pysisporinus vitreus fungal strains for further experiments in a large research project on copper tolerance of P. vitreus by chemotropic test, choice test, and agar plate toxicity tests and determination of the effect of various ions on oxalic acid secretion by these white rot fungi. In the project, it is also aimed to run fungal decay tests to dete...

Extraction of fungal colorants for their use in coloured coatings for wood
2022 - IRG/WP 22-40938
Microorganisms are highly interesting for the production of useful metabolites. Such metabolites are e.g. colorants, that can easily be produced on industrial scale and low material costs. To date some microbial produced colorants are used in textile- and food industry because of their low toxicity and sustainability compared to synthetically produced colorants. However, little is known about the ...

Evaluation of different wood by-products for sustainable building biomaterial production using fungal mycelium
2022 - IRG/WP 22-50373
As human population increases, the demand for new innovative, sustainable, and low impact construction materials also grows. Mycelium-based composites have shown to be an excellent alternative for traditional products ranging from low-density objects to semi-structural applications. They also present the advantage of using the waste streams from other productive processes as feedstock, enabling th...

CIOL Wood - towards industrial scale production
2023 - IRG/WP 23-40980
CIOL® is a new, low cost, non-toxic wood modification system, needed to replace traditional and non-sustainable alternatives with great potential. It’s important to find sustainable, environmentally friendly replacements to heavy metals and biocides. In the new European Bauhaus, Ursula Von der Leyen, president of the European commission, talks about how new living environment should be beautifu...

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...
