Needs for wood durability research on planted tree species in the tropics
2008 - IRG/WP 08-10651
The area of forest plantation has been expanding especially in tropical Asia since 1990’s. Most of them are developed for pulp and paper industries and planted with fast growing trees. It is expected that wood from those fast growing trees are also used for value added products such as sawn timber. In order to promote the utilization of fast wood as the resource of value added products, natural...

Assessment of antagonism between lignicolous microorganisms: Research on possible use to preserve wood poles
2010 - IRG/WP 10-10718
Biological environments contain a certain number of microbial populations which, within a given ecological niche, display various relations ranging from symbiosis to parasitism. Researchers have been interested in these types of relations for around fifty years, especially in one very particular type of relationship: the antagonism exerted between individuals of the same microbial population. Toda...

CreoSub – New protection technology to substitute creosote in railway sleepers, timber bridges, and utility poles
2014 - IRG/WP 14-30644
Creosote oil is one of the oldest industrially used wood preservatives. Due to its toxic profile, the European Commission has restricted the use of creosote specific applications, but it is highly controversial within the European Commission. Its approval for use after 2018 is very questionable and may depend on derived research results until then, i.e., the viability of alternatives developed to ...

The potential of 2D NIR imaging for wood protection research
2015 - IRG/WP 15-20566
Investigating wood and wood-based materials using infrared spectroscopy has since long been explored. Recently, image-based systems have been developed that are used in food and pharmaceutical industries for rapid screening. Such hyperspectral cameras are able to collect spatial and spectral information simultaneously, resulting in a volume with a spectral profile for each pixel of the image. We p...

Factors Affecting Performance of Preserved Wood Decking Against Decay Fungi
2015 - IRG/WP 15-30663
Decking is the largest market for residential preserved wood in the United States. Preserved decking must be resistant to colonization by decay fungi initiating from spores, and occasionally from mycelia due to elevated soil levels or adjacent untreated wood. The most vulnerable parts of a preserved wood deck are untreated, or under-treated, wood that becomes exposed by field cuts and checking. Fi...

Commercial Timbers of Kenya
2016 - IRG/WP 16-10876
The global timber trade has for years been too familiar with an assortment of available African timbers, reputed for their appearance in terms of colour, grain, pattern and durability. African forests are fast disappearing through over-exploitation as a result of demand for agricultural land. Kenya, the home of some of these valuable hardwoods, has been similarly affected, with its forest land cov...

Towards better integration of wood protection in the forestry wood industry chain - a case study on hybrid poplar
2019 - IRG/WP 19-50359
Wood and wood products are limited in service life as in the forest ecosystem trees at end of their life are degraded to re-enter the bio-geochemical cycle. Humans can select wood species with a level of natural durability fit for an envisaged end use. Mainly those applications that require a long service life under conditions that are similar to those at soil level in a forest ecosystem have been...
