Effect of heating on aldehydes emissions from solid wood
2011 - IRG/WP 10-50277
We have found that acetaldehyde, a probable human carcinogen, is produced from wood through reaction with ethanol. Alcohols are increasingly being used in houses and buildings for cleaning purposes. Acetaldehyde emission from solid wood has been attributed to ethanol acidification by enzymes such as ethanol dehydrogenase. Heating could inactivate these enzymes. In this study, the effects of heatin...

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...

Declaring life cycle inventory of toxicity related emissions in environmental product declarations of preservative treated wood products
2018 - IRG/WP 18-50339
Life cycle assessment (LCA) including impacts on toxicity for preservative treated wood has been shown to have large uncertainties. With the growing demand for verified LCA in environmental product declarations (EPD), the need for reliable data is crucial for realistic assessment of wood products. Uncertainty is caused by several issues such as service life prediction, leaching rates and calculati...

Aiming for eco-friendly log production and wooden construction!
2021 - IRG/WP 21-50365
In order to reduce greenhouse gas (GHG) emissions to zero by 2050 in the fields of forest and forest products, it is necessary to promote appropriate management and renewal of planted forests, and development of wooden building materials and the wooden construction of mid-to-high-rise buildings with lower GHG emissions. Unless we also try to reduce the environmental loads other than GHG for such d...
