Liquefaction of woody waste: A novel approach in wood protection from CNSL based liquefied wood polyols
2017 - IRG/WP 17-30711
Liquefaction of lingo-cellulosic biomass is one of the thermo-chemical conversion processes for developing new materials, adhesives, preservatives and energy systems. The process also provides an opportunity to utilize waste wood such as saw-dust, woody wastes, branches and twigs for the development of value added products. Thus, this research paper deals with an investigation of antifungal and a...

Treatability of beechwood railway sleepers with potential creosote substitutes
2017 - IRG/WP 17-40790
Maintenance of an efficient railway infrastructure still requires the use of wooden railway sleepers, particularly because wooden sleepers have more favourable properties for intensified vibrations than concrete or steel sleepers. Creosote, used for decades for the impregnation of railway sleepers, will possibly no longer be available for this application due to European legislation. This reveals ...

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...

Biocontrol of wood decay insects and nematodes as an alternative to traditional chemical treatments
2018 - IRG/WP 18-10914
The protection of wood has been defined until relatively recently, as the application of a chemical to increase its durability. On the other hand, society is becoming more and more demanding in terms of the use of products which have the minimum ecological impact. This has led many countries to reduce the list of biocidal products that can be used (European Biocides Regulation), therefore it is ne...

Chemical defense of trees and wood natural durability: from protection to valorization
2019 - IRG/WP 19-10943
Natural durability of wood is defined as “the inherent resistance of wood against various wood-destroying organisms” (European standard EN 350-1). This property is due in particular to heartwood extractives. However, the wood natural durability is included in a wider defense system, and other organs such as bark and roots also host protective compounds. Studying the mechanisms on which global ...

Service life planning of wooden structures: Mathematical prediction models versus professional experience
2019 - IRG/WP 19-20663
During the last 15 years, enormous efforts have been made in developing models for predicting the service life of wooden structures and components. Currently, a framework of how exposure, dimension, design details and the material-intrinsic and the ability to take up and release water can be linked to model the moisture risk in wood products is in principle available.
The aim of this study was to...
