Oak maturation casks at the Rodenbach brewery, an industrial heritage of the Flemish Community requiring protective measures
2017 - IRG/WP 17-10898
Brewery Rodenbach has world-renowned cask halls with close to 300 oak casks, some of these big maturation casks are 150 years old and this is protected as part of the industrial heritage of the Flemish Community. Since some of these maturation casks or “foeders” were the last decades no longer fully in use some parameters of their physical condition might have increased incidence of fungal dec...

A Green and Novel Technology for Recovering Copper and Wood from Treated Wood Waste – Part II: Optimization, copper metal recovery, and process design
2017 - IRG/WP 17-50326
The US consumes 70 million pounds of copper and produces 580 million cubic feet treated wood annually. The EPA disallows burning and reusing treated wood waste due to health/environmental concerns. Vast quantities of copper and wood are landfilled. Two safe and low cost extraction systems, citric acid and ammonium citrate, were identified in Part I of this study. In Part II of the study, effects o...

Thermodynamic properties of furfurylated wood during moisture adsorption process
2018 - IRG/WP 18-40828
Furfurylation of wood seems a promising wood modification method considering the wide raw material source of furfuryl alcohol (FA) and overall performance of FA modified wood. However, the modification mechanism of furfurylation is still not clear and needs further investigation. In this study, poplar (Populus cathayana Rehd.) samples with the size of 1(R) mm × Ф4 mm, were impregnated with ...

In-line quality control of the film thickness in industrial coating processes for exterior cladding
2018 - IRG/WP 18-40835
The production of industrially coated wood cladding has been strongly increasing in Scandinavia during the last years. In the beginning of this development, industrial coating processes included solely the application of pigmented primers; these however provide only a short protection of the wood surface and the application of a top coat is required during the first 6 to 12 months after mounting t...

Visualization of Feeding Process of Larvae of the Wood-boring Beetles Using X-ray Computer Tomography
2019 - IRG/WP 19-10953
X-ray computer tomography (CT) was applied to observe the movement of the larvae of the wood-boring beetles Lyctus brunneus, Lyctus africanus, and Heterobostrychus aequalis inside the infested wood specimens. The larvae bred with artificial diet were inserted into the hole of wood specimens of rubber wood Hevea spp. or Japanese oak Quercus crispula. The wood specimens with larvae were scanned usin...

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...

GDR3544 “Science du Bois” - Academic and Industrial French Partnerships on Wood Science
2019 - IRG/WP 19-50362
The wood sciences are currently practiced by a very diverse community of disciplines, themes and institutional contexts of different actors. The Research Group in Wood Sciences (GDR3544 "Sciences du Bois") was created in 2012 by the National Center for Scientific Research (CNRS), and renewed from 2016 to 2020.
The objectives of GDR " Science du Bois " are to manage the coordination of wood scienc...

Investigations into the use of Maleic Anhydride/Sodium Hypophosphite as a Wood Modification Process
2020 - IRG/WP 20-40891
The formation of crosslinked bonds between wood constituents is believed to be an effective way to stabilize wood against wet conditions. The possibility to use maleic anhydride (MA) combined with sodium hypophosphite (SHP) as crosslinking agents was studied, using Scots pine sapwood and a model compound. The modified wood showed weight gain and bulking effect after treatment and subsequent Soxhle...

An Update on the Status of Industrial Heavy-Duty Preservatives in Europe
2022 - IRG/WP 22-30762
Creosote has been used for over 150 years for preservation of heavy duty industrial timbers such as railway sleepers, utility poles, and agricultural posts. The regulatory regimes in place today across Europe (eg EU & GB Biocidal Products Regulation (BPR)) require a detailed assessment of the environmental and human health properties of wood preservatives at both the active substance and product l...

Field test methods as long-term aging – report of selective wood properties
2023 - IRG/WP 23-40962
Wood samples from a long-term field test are a valuable compendium of information about the material in the context of its aging processes. In the current work, wood samples from the round-robin test within the ECOMOD project were used as a material for the natural aging process (III and IV class of utility). The research scope was to determine selected properties of this wood which can be partial...

New wood-modification process based on grafted urethane groups: Durability of carbamamylated Scots pine (Pinus sylvestris L.) wood
2023 - IRG/WP 23-40974
Substituting commonly used toxic preservatives with wood modification treatments can make the wood material less prone to water and moisture uptake. This approach favours a more sustainable protection of wood against biodegradation. In this study, Scots pine sapwood was full-cell impregnated with an aqueous solution of urea (30%), dried at 40°C for 24h, and subsequently heat-treated at 150°C for...

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...
