Green Coloration of Wood in the Forest and Laboratory by Chlorociboria spp. – Applications for Furniture
2019 - IRG/WP 19-10947
Discoloration of wood caused by living saprophytic fungi is commonly found on lumber. These fungi do not destroy the integrity of wood, but the discolorations they cause are often considered undesirable. In Tunbrigde Wells (Great Britain), seldomly found green colored wood, usually considered commercially irrelevant, was valued for use in restoration of wood inlay artwork. The aim of this researc...

Visual assessment of longitudinal wheel timbers and assessing the feasibility of extending wheel timber service life in the UK railway network
2019 - IRG/WP 19-20651
Timber has been a versatile building material for centuries and during the start of the Railway Age in the nineteenth century it was in considerable demand for use in the railway network, particularly bridge building. Timber is still in service and widely used throughout the UK railway network. The resilience and favourable strength to weight ratio and its relative ease of fabrication make it an...

Protecting Sustainable Wood Infrastructure ̶ Improving the Performance of Poles, Piles, Ties & Timbers with Dual Treatments
2019 - IRG/WP 19-30735
Wood is by far the best structural material in terms of environmental impact, as shown by a number of LCA studies. This environmental impact superiority can be improved if the longevity of the commodity is extended. The main durability concern in large cross-section treated materials is the susceptibility of the heartwood to decay, as it is not typically treatable using traditional methods. This ...

Potential of totora and derivatives as sustainable lignocellulosic material
2019 - IRG/WP 19-40859
Totora (Schoenoplectus californicus C.A. Mey. Soják) is a macrophyte from the Cyperaceae family that grows in the Americas from California to Chile. This plant has long been used by several cultures such as the Ohlone in California, the Moche in Peru, or the Incas in Los Andes. Some communities have maintained its traditional use until the present, such as the communities living nearby Lake San P...

Effect of damage to polyurea coatings on metal losses from ammoniacal copper zinc arsenate treated Douglas-fir pile sections
2019 - IRG/WP 19-40867
Metal-based preservatives remain the most widely used treatments for protecting wood in soil or water contact. While these treatments are highly effective, one drawback is a tendency for small amounts of metal to migrate into the surrounding environment. The greatest risk in this regard is copper because many organisms are highly sensitive to this metal. While post treatment practices can reduce ...

Sustainable wood products development in a bio-refinery perspective: case studies in French Guiana
2022 - IRG/WP 22-50370
French Guiana, by its belonging to the Amazon region and the Guiana shield, has very specific environmental and social characteristics in the French regional ensemble. In this context, it is thus necessary to find how to reconcile the economic development of the territory, the conservation of biodiversity and the recognition of local knowledge and practices. Bringing together multidisciplinary ski...

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...

Management of invasive West Indian drywood termite in Queensland: Transition from mandatory to voluntary treatment
2023 - IRG/WP 23-11002
Cryptotermes brevis, the West Indian drywood termite (WIDT) is the most destructive drywood termite globally. It is capable of infesting both softwoods and hardwoods in timber structures. In Australia C. brevis was first discovered in 1940s and later an established infestation was discovered in Maryborough, Queensland in 1966 and then in Brisbane and Bundaberg in 1975. In 1977 the Queensland Gover...

Susceptibility of selected Australian commercial timbers to West Indian drywood termite Cryptotermes brevis
2023 - IRG/WP 23-11003
West Indian drywood termite (Cryptotermes brevis) is a globally distributed timber pest and is invasive in Queensland, Australia, causing widespread damage to structures and large economic impacts in control and repair costs. Despite this, the knowledge of which specific timbers are susceptible to attack is limited and requires investigation. Two six-week feeding trials were performed, exposing se...

Subterranean termite control management in urban areas in Spain. Example of management in the old town of Vigo, Spain
2023 - IRG/WP 23-11006
Termites are wood destroying insects always present in the nature with an important wood decomposition function. In Europe, they are mainly 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...

Emerging wood nanotechnologies towards sustainable application and preservation
2023 - IRG/WP 23-40959
Wood is one of the most abundant biomaterials on earth and has been used for construction historically. Although existing wood composites are commercially successful, materials development has not targeted nano-structural control of the wood cell wall, which could extend the property range. The high porosity and permeability of wood scaffold provide excellent opportunities for material infiltratio...

UV protection and dimensional stability of lignin-based wood treatments
2023 - IRG/WP 23-40979
New developments in the field of wood modification aim to enhance the intrinsic properties of natural timber. The limitation of wood should be preferably achieved with biobased ingredients and efficient, eco-friendly treatments possessing low environmental impact. Consequently, new solutions assuring expected properties and functionality over elongated service life and reducing the risk of product...

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...
