Effectivity of zinc borate in medium density fiberboard (MDF) for ground proximity testing
2024 - IRG/WP 24-20723
Medium-density fiberboard (MDF) is one of the most used and versatile wood composites. Most of its use has been focused on interior applications. Adhesives such as p-MDI (polymeric methyl diphenyl diisocyanate) provide MDF with a better performance against moisture, but resistance against decay is also required for outdoor use. A mix of wood fibers, p-MDI, and 0.75%-1.5% of ZB was made to produce ...

Field performance of preserved shakes and shingles
2024 - IRG/WP 24-41000
Wood shakes and shingles are used in applications where they are at risk of decay, either in sidewall (UC3.1) or roofing (UC3.2) applications. Material durability may come from using the heartwood of naturally durable species, using preservative treatments, or both. Through a series of long-term field tests, this paper explores the performance of naturally durable and preserved shakes and shingles...

Biofabrication of composite materials – Utilizing lignocellulosic biomass and mycelium in 3D printing
2024 - IRG/WP 24-50396
In this research, we investigated the potential of utilising lignocellulosic biomass and mycelium for 3D printing applications to develop sustainable biocomposite materials. Our study began with a systematic investigation of various fungal cultures, including Pleurotus ostreatus, Schizophyllum commune, Ganoderma resinaceum, Trametes versicolor and Gloeophyllum trabeum, in combination with substrat...

A comparison of methods – how to achieve a robust and conclusive durability classification of wood
2025 - IRG/WP 25-11063
The biological durability of wood is a relative and unitless size, and therefore wood species and wood-based materials are assigned to durability classes (DC). In Europe, such classes are based on a variety of measures, which can be absolute or relative to a non-durable reference species. The aim of efforts to develop and standardise methods for determining biological durability should be to ensur...

Detecting wood-decay fungi in walls: a non-destructive approach with an electronic nose
2025 - IRG/WP 25-11070
Wood-decay fungi degrade the structural integrity and safety of wooden buildings, leading to potential hazards and reduced durability. Conventional detection methods, such as visual inspection and destructive sampling, are often impractical for concealed spaces, such as those within walls or beneath floors. These methods often require specialised training and costly equipment, making non-destructi...

Novel treatments of solid wood - studies into the use of imidazole and succinimide
2025 - IRG/WP 25-30817
Recent activities have focussed on the use of ionic liquids (ILs) in wood treatments and bioprocessing. Most ILs are based on imidazolium systems, so it was decided to investigate the potential of imidazole as a treatment, along with another heterocyclic compound, namely succinimide. Thus, modification of Scots pine sapwood (Pinus sylvestris L.) with heterocyclic compounds, imidazole and succinimi...

AI Models for Accelerating Wood Protection Testing: Development of Predictive Tools Based on Long-Term Field Test Data
2025 - IRG/WP 25-41023
In this study, we present the development of DecAI, an artificial intelligence (AI) model designed to optimise and accelerate performance evaluations of wood protection products in the European EN 330:2014 "Field test: L-joint method." The Danish Technological Institute (DTI) compiled a dataset of over 100,000 data points from approx.10,000 L-joint samples collected over +15 years at field sites i...

A Case Study of Vogvarjeva hiša, a Local Ethnographic Museum
2025 - IRG/WP 25-41027
The Vogvarjeva hiša in Spodnje Duplje, Slovenia, is an example of traditional 18th Century wooden architecture and an important element of the region’s cultural heritage. The building was constructed from local timber on stone foundations and reflects the traditional rural building techniques of the Gorenjska region. Since it was declared a cultural monument in 1985, it has functioned as an eth...

Transformation of bamboo: From multiscale fibers to robust and degradable cellulose-based materials for plastic substitution
2025 - IRG/WP 25-41032
Bamboo is an ideal candidate to replace traditional plastics, reduce environmental pollution, and promote harmony between nature and humanity owing to its rapid growth and renewability. However, achieving arbitrary shape-shifting of bamboo while retaining its high strength and degradability remains challenging. This study used multiscale interface engineering to transform bamboo into a robust, bio...

Biocomposites based on fungal mycelium and beech particles impregnated with BPCM (bio-phase change material) for thermal energy storage
2025 - IRG/WP 25-41034
The building sector is a major contributor to Europe's carbon emissions, and transition to a bio-based economy is essential for achieving long-term sustainability goals. The European Union has set ambitious targets for climate-neutral heating and cooling by 2050, which requires the widespread adoption of energy-efficient and environmentally friendly technologies. A key element in this transition i...

Non-destructive methods for field assessment of wood biodeterioration in hardwood trailer decks exposed to tropical environments
2025 - IRG/WP 25-41039
Apitong (Dipterocarpus spp.), an increasingly rare tropical hardwood from the rainforest in Southeast Asia, has long been used as decking materials for open-bed trailers and trucks across North America. As the natural population of Apitong trees steadily declines, there is an urgent need to find sustainable, domestically sourced alternatives for trailer decking. A recent project evaluated the perf...

Recycling wood treated with copper-based preservatives to produce hard carbon materials for energy storage applications
2025 - IRG/WP 25-50401
In this study, we explored the possibility of recycling wood treated with copper-based preservatives to produce hard carbon materials for use in energy storage devices. We pyrolsed both untreated and copper-treated wood into hard carbon, conducted microstructural and physicochemical characterisation, prepared electrode materials, and evaluated their electrochemical performance in sodium-ion batter...
