Performance of treated Malaysian semantang bamboo (Gigantochloa scortechinii) - field and laboratory durability evaluation
2023 - IRG/WP 23-30788
Field performance of sematan bamboo, Gigantochloa scortechinii was evaluated under the Malaysian tropical climate, along with laboratory evaluation to white-rot fungi and mold. Starch was removed from the bamboo by submerging the bamboo in the river for 6-8 weeks, kiln-dried and cut to 300 mm (L) round bamboo and 25 mm (W) x 50 mm (L) stripe for the field and laboratory test respectively. Bamboo w...

Envelope wood protection against subterranean termites under H2-hazard class tropical environment by a new generation wood preservative with vegetal extracts-cypermethrin mixtures
2023 - IRG/WP 23-30795
Wood protection industries in progressive economies globally are compelled to develop cost-effective, environmentally acceptable wood treatment solutions for long term carbon storage in wood materials/products while appealing to consumer demands for low environmental impact treated wood. A new generation wood preservative, based in part on 2% vegetal extracts and 0.16% cypermethrin components, has...

Environmental Benefits of Wood Preservation
2023 - IRG/WP 23-50377
Over the past decade or two, many people have become significantly more aware and concerned about the global environment and the health of our planet. Building with wood products from sustainably managed forests carries significant environmental benefits. The ability of a growing tree to absorb carbon dioxide (CO2) and sequester the carbon is beneficial in the role of combating rising CO2 levels...

Manipulation of the hierarchical wood structure for extended carbon storage in the built environment
2023 - IRG/WP 23-50381
The sustainable processing of trees into construction materials can act as carbon storage. Carbon storage in durable sustainable wooden construction material has cumulative effects and net gain in storage in the built environment that can be offset by net losses in forest carbon by cutting the tree. Carbon storage for an extended period plays an important role in the mitigation of CO2 emissions an...

Laboratory evaluation of PA1b, an insecticidal protein extracted from pea seeds (Pisum sativum), as bait active ingredient against the subterranean termite Coptotermes gestroi (Blattodea: Rhinotermitidae) in tropical zones
2024 - IRG/WP 24-11038
Coptotermes gestroi (Wassman 1896) is one of the worst pests in tropic areas, economically. Two types of curative methods are used since decades to eliminate colonies that attack constructions: injection of biocidal treatment solutions on wood, walls and soil, and population control using baits. In application of the current regulations, the first technique can no longer be used in Europe, to lim...

Laboratory and field evaluations of bio-based termiticide containing Arnica extract from Berkem Biosolutions® against native and Formosan subterranean termites
2024 - IRG/WP 24-11049
Arnica extract from Berkem Biosolutions® is a 100% plant-based ingredient, rich in active molecules, particularly polyphenols, specially adapted to the needs and challenges of termite protection. The efficacy performance of a bio-based termiticide product containing Arnica extract from Berkem Biosolutions® had been evaluated both in soil treatment and in wood protection treatment against native ...

Studies on the treatability of selected pine species and corresponding efficacies of a new non-biocidal treatment
2024 - IRG/WP 24-20721
Wood decay caused by fungi may reduce the service life of wood in outdoor applications. Since moisture conditions in wood occur as one of the most crucial parameters for fungal decay, chemical modifications, which affect the latter, may increase the resistance of wood against such organisms. Usually, pine sapwood is easier to chemically treat than heartwood, as the former generally shows good perm...

Phytosanitary heat treatment of wood in a laboratory drying oven and, in a pilot-scale kiln using the house longhorn beetle (Hylotrupes bajulus) larvae as a model
2024 - IRG/WP 24-20722
International trade in wood products brings the risk of the movement of tree pests which can cause devasting ecosystem and economic damage. International phytosanitary guidelines were created to help countries that import wood products. Import requirements intend to minimize pest spreading. Thus, the ISPM 15 (International Standards for Phytosanitary Measures No. 15) which specifies the “Regulat...

Copper migration from preservative-treated Douglas-fir decking: models vs laboratory leaching data
2024 - IRG/WP 24-50390
The ability of a model to predict copper migration from Douglas-fir treated with organic metallic substances into a freshwater slough was evaluated against data generated through simulated overhead leaching. The model predicted very high loadings of ammoniacal copper zinc arsenate, alkaline copper quaternary or copper azole that had the potential to impact water quality while data from the exper...
