Applicability of wood durability testing methods to bio-based building materials
2015 - IRG/WP 15-20561
It is well known that organic materials may be susceptible to attack from a range of fungal organisms and any bio-based material used in locations where there is the possibility of microbiological activity must be expected to be able to withstand or prevent such attack. There are a wide range of test methods and standards in place to test susceptibility although most of these test individual compo...

Performance of bio-based building materials – viewpoints from the first year of COST Action FP1303
2015 - IRG/WP 15-20572
Maintaining and expanding the market potential for bio-based building products in indoor and outdoor construction uses remains a key activity for industries in the forestry and biotechnological sector, particularly in Europe. Whilst there are ongoing activities within IRG for collecting and populating a database on performance on wood, the performance data for many other (i.e. non-wood) "environme...

Laboratory test to determine the effect on durability of combining biobased building materials with timber in construction
2017 - IRG/WP 17-20604
The use of Structural Insulated panels is a construction approach that is seeing more abundant use and is becoming a widely available method. Preformed units are usually a composite structure which often include a range of bio-based materials such as timber, wool or straw. Traditional laboratory based wood decay tests do not take into account this combination of biobased materials and it may be po...

Comparative study on the efficacy of biobased wood preservative over conventional wood preservatives against fungi and termites
2022 - IRG/WP 22-30761
The current focus of wood preservation research is on developing wood preservatives from natural and environmentally compatible compounds for industrial application. Liquefaction of wood is one of the promising approaches to utilize woody waste where the wood powder is converted into a chemically active liquid with the help of a liquefying agent like phenol, cresol, plant-based solvent as CNSL and...

Modification of wood by fast pyrolysis bio-oil – the NewWave project concept for bio-based wood treatment
2023 - IRG/WP 23-40990
The NewWave project aims to contribute to building a circular economy by introducing sustainable raw materials in different manufacturing lines, replacing toxic chemicals and lowering the environmental footprint of the products. The raw materials are obtained from the thermochemical fractionation of biomass. This process converts biomass residues by fast pyrolysis into Fast Pyrolysis Bio-Oil (FPBO...

Efficacy performance of Pea Extract as bait toxicant for termite control in Reunion Island
2024 - IRG/WP 24-11050
This study was carried out to determine the toxicity of Pisum sativum L., extract (Pea Extract) for the subterranean termite, Coptotermes gestroi (Isoptera: Rhinotermitidae). Yellow field peas (Pisum sativum L.) are particularly rich in protein. A solid-liquid hydroalcoholic extraction process was employed on the dried form of pea seeds to obtain one particular peptide PA1b (Pea Albumin 1, subunit...

The potential of Wacapou (Vouacapoua americana) extracts to develop new biobased protective solutions for white woods
2024 - IRG/WP 24-20724
The valorisation of Amazonian wood residues into active chemical compounds could be an eco-friendly, cost effective and valuable way to develop wood preservatives formulations in order to enhance the decay and termite resistances of low durable wood species, by impregnation processes. Wacapou (Vouacapoua spp., Fabaceae) is a well-known Guianese wood species for its use in local wood construction ...
