Evaluating the potential for re-using timber from deconstructed sea defence groynes from the Bournemouth groyne field
2024 - IRG/WP 24-50397
In the shadow of a looming climate crisis, the modern age construction industry is evolving. The for implementing sustainable practices has never been greater and the potential role of the circular economy is front and centre. It can play a pivotal role in transforming the industry by promoting sustainable practices which emphasise the need to reduce consumption of natural resources. Re-using timb...

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...

Evaluating the Efficacy of Arnica Extract-Based Termiticide from Berkem Biosolutions® in Subterranean Termite Control: A Comprehensive Laboratory and Four-Year Field Study
2025 - IRG/WP 25-20731
Subterranean termites pose significant threats to wooden structures. This study evaluated the efficacy of a bio-based termiticide product containing Arnica extract from Berkem Biosolutions® in controlling subterranean termites in both laboratory and field conditions. The laboratory assessments utilised “the Bottle H” test unit, adhering to the Japan Wood Preservation Association (JWPA) standa...

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...

Wood phytosanitation: which Standard should be applied?
2025 - IRG/WP 25-20748
The international Standards ISPM 15 and ISPM 39 are both essential tools for safeguarding global plant health, but they serve different purposes, and apply to different aspects of international trade. ISPM 15 focuses on wood packaging material and mandates Standardised treatments and marking, while ISPM 39 addresses international movement of wood and emphasises risk assessment and tailored phytosa...

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...

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...

Durability and service life of wood in constructions. The Spanish approach of European Standard EN 460
2025 - IRG/WP 25-41028
The durability of wood is an important factor to be considered in the construction influencing in final durability and expected service life of a wood product in construction. There are many factors influencing in the durability (service life) of a wood in construction: Natural durability of wood species, preservative treatments and protection by design; combined with the variability of environmen...

Large scale management of subterranean termite attacks in urban areas in Spain. Spanish standard UNE 56418:2016
2025 - IRG/WP 25-41036
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 attacking wood and wood-based elements in the buildings. It is estimated about 80% of old historic towns in Spain are affected by subterranean termite attack and it is one of the m...

Durability Enhancement of US Hardwoods for Use in Open Trailer Decks
2025 - IRG/WP 25-41048
Apitong, a tropical hardwood derived from endangered species within Dipterocarpus genus, has long been used as a decking material for open flat-bed and lowboy trailers in the U.S. However, as more Dipterocarpus species are classified as endangered and critically endangered by International Union for Conservation of Nature (IUCN) due to the declining population of Apitong trees, there is a growing ...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...
