Xylophene AS™, the challenge of developing a modern antisapstain formulation for the french market
2000 - IRG/WP 00-30250
In France Sodium Pentachlorophenol (NaPCP) has been used for more than 40 years for the protection of freshly cut and unseasoned lumber. The French sawmill industry requires a protection of 6 months and maximum 10% surface infection by moulds and/or sapstain fungi. However, this active substance did have some serious environmental flaws and no authorisation was granted for a direct contact of NaPC...

Effects of new fixative additives on leachability of boron wood preservatives
2009 - IRG/WP 09-30507
Borates are well known with their protective capacity against both fungi and insects with low mammalian toxicity and environmental acceptable. However, boron itself does not ensure the appropriate protection for wood in the exterior applications because of their easily depletion from the treated wood under wet conditions. In this study, the potential use of monoglyceride and polyvinyl alcohol prod...

Potential of antifungal and antitermitic activity of several essential oils
2009 - IRG/WP 09-30515
In the recent years, there has been an increasing concern regarding the safety of wood preservatives. Many research groups have examined the potential of essential oils as biocide based on their biological activity. This paper described the antitermitic and antifungal activity of twenty four essential oils from different plant species. The termicidal activity was carried out with a no-choice test...

Effects of polyvinyl alcohol on leachability and efficacy of boron wood preservatives against fungal decay and termites attack
2010 - IRG/WP 10-30526
In this study, the use of polyvinyl alcohol (PVA) as boron fixative agent was investigated. Two levels of PVA (2.5 and 4%) were evaluated with disodium octaborate tetrahydrate (DOT) at three concentrations (1, 2 and 4% boric acid equivalent (BAE) using a double vacuum impregnation processes on Scots pine sapwood specimens. Leaching was performed according to a laboratory leaching procedure. Boron ...

Decontamination of sludges, liquids and soils polluted by “class 1, 2 & 3a” and “temporary” wood treatment products from dipping tanks
2016 - IRG/WP 16-50315
Wood is one of the most widely used building materials as it is easy to find and process. As an organic material, time leads to a degradation of its substance, and even more so when it is exposed to pathogens such as fungi, bacteria and insects. In order to try and inhibit this phenomenon, several preservation treatments have been developed and applied thanks to the production of chemical biocides...

From wood protection to health protection: larvicidal potential of formulations containing Sextonia rubra wood residues extract against Aedes aegypti mosquitoes
2020 - IRG/WP 20-10968
French Guiana is a French overseas territory almost entirely covered by Amazonian rainforest and characterized by its incredible biodiversity. Several woody species harboured by this tropical forest are exploited sustainably for timber industry. They are commercialized notably for carpentry and outdoor applications because of their remarkable natural durability. Among them, stand Dicorynia guianen...

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...
