VOC-free remedial treatment agent on organic solvent basis with surface cleaning by photocatalysis using titanium dioxide
2014 - IRG/WP 14-40651
Due to the EU Regulations according to the harmonisation of the European market of biocidal products and the EU Regulations regarding emissions of volatile organic compounds in residential properties a new VOC free yet organic solvent based remedial treatment agent is introduced including a potential method to clean up the wooden surface of remaining biocides after a remedial treatment using photo...

Bio-friendly preservative systems for enhanced wood durability - the first periodic report on DURAWOOD
2015 - IRG/WP 15-30677
The objective of the paper is the DURAWOOD scientific project carried out within Polish-Norwegian Research Programme, which lasts from September 2013 till August 2016. The aim of the project concentrates on the developing of a new, eco-friendly and biocide-free wood protective systems as an alternative to traditional, commonly used preservatives or coatings, containing biocides. Several wood prese...

Application of nanoparticles of silver and nanoparticles of titanium dioxide in reinforcement of wood and coating for wood in Costa Rica
2015 - IRG/WP 15-40698
Wood is one of the most widely used materials in last 20 years by society in many applications, with a considerable proportion of this material coming from forest plantations. Plantations usually produce timber with reduced strength properties and low natural durability. On the other hand, nanotechnology applications have the potential to increase wood properties. Likewise, nanotechnology cannot o...

Life cycle assessment of creosote treated wood and tall oil treated wood with focus on end-of-life
2016 - IRG/WP 16-50320
The use of creosote for protecting wood products in heavy-duty application outdoors has been common for many years, but stricter regulations have limited creosote’s use. Life cycle assessments (LCA) have shown that in some applications alternatives to creosote treated products do not have less environmental impacts. Searching for alternatives to creosote, tall-oil-based preservatives have been ...

How carbon stored in harvested wood products contribute in a greenhouse gas accounting perspective
2017 - IRG/WP 17-50327
In 2014 the net annual removal by Norwegian forests was 30.4 mill ton CO2-eqvivalents while the emissions in other sectors was 53.2 mill ton CO2-eqvivalents. Hence, forests can play a major role in the national greenhouse gas balance. But forests also contribute to the carbon pool stored in wood products. The aim of this paper is, by using Norway as an example, to illustrate how the greenhouse gas...

Marine borer resistance of various wood materials in Japan
2021 - IRG/WP 21-10983
Wood resistance against marine borer was intensively studied in the 1940s in Japan, but the research activities on the subject diminished afterward, as the use of wooden marine structures and ships decreased. Today, however, use of wood as a construction material is officially promoted for its environmental benefits. The author started to immerse some wood materials in the seawater pool at PARI ...

Carbon footprint of a cross laminated timber building – Torvbraten school case study
2021 - IRG/WP 21-50366
Torvbråten school is a public school in Asker, Norway, that has reached many sustainability goals. The school was the second in Norway to have Nordic Swan Ecolabel and has a 60 % reduction in carbon footprint compared to the reference benchmark. The building is made of cross laminated timber (CLT) and extensive wood use in general. From a wood protection viewpoint, will this sustainability sustai...

Comparative study of the properties of silicate coatings with different mineral pigments (titanium dioxide, iron (III) oxide, copper (II) oxide) on the surface of wood
2022 - IRG/WP 22-40936
Silicate coatings are attractive alternatives to conventional organic-based coatings for wood protection. In this work, silicate coatings were prepared with a potassium silicate binder modified with a methyl siliconate solution, and three types of mineral pigments titanium dioxide, iron (III) oxide and copper (II) oxide. The coatings were applied on beech wood and cured under ambient conditions. T...

Make do and mend: Re-using timber in Smithfield Market
2022 - IRG/WP 22-50371
Historic buildings are part of our built environment. They are a record of how construction and use of materials have evolved and provide excellent opportunities for regeneration of urban areas. Moreover, re-using these buildings and as much of the material within, contributes to the Green Revolution.
Currently, there is tremendous growth in green construction and as Bob Dylan once said, “the t...

Long-term field performance of a carbon-based preservative in ground contact test conditions
2023 - IRG/WP 23-30781
Carbon-based preservatives have demonstrated reasonable long-term field performance in above ground testing. This study examines the performance of a carbon-based preservative formulation containing quaternary ammonium compounds and tebuconazole as a treatment for three softwood species exposed in ground contact at two sites in Canada. The treatment was associated with improved decay resistance an...

Carbon nanotubes and multifunctional silane additive as fillers in PF resin and their effect on the composite flammability
2023 - IRG/WP 23-30783
Adhesive bonds are the most readily modifiable and, at the same time, give the greatest scope for modification of components of lignocellulosic composites. A study of a manufactured lignocellulosic composite based on a phenol-formaldehyde resin and pine veneer with additives modifying the properties of the resin was made. The multifunctional commercial silicon oxide Protectosil 851 and multi-walle...

Environmental Benefits of Wood Preservation
2023 - IRG/WP 23-50377
Over the past decade or two, many people have become significantly more aware and concerned about the global environment and the health of our planet. Building with wood products from sustainably managed forests carries significant environmental benefits. The ability of a growing tree to absorb carbon dioxide (CO2) and sequester the carbon is beneficial in the role of combating rising CO2 levels...

Manipulation of the hierarchical wood structure for extended carbon storage in the built environment
2023 - IRG/WP 23-50381
The sustainable processing of trees into construction materials can act as carbon storage. Carbon storage in durable sustainable wooden construction material has cumulative effects and net gain in storage in the built environment that can be offset by net losses in forest carbon by cutting the tree. Carbon storage for an extended period plays an important role in the mitigation of CO2 emissions an...
