Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

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 ...

X-ray micro-computed tomography of copper distribution in CA, ACQ and MCA treated wood and changes in microstructure of ACQ-treated southern pine following natural weathering
2024 - IRG/WP 24-20707
We hypothesized that X-ray micro-CT would be able to visualize: (a) the distribution of copper in CA-treated southern pine; and (b) microstructural changes in ACQ-treated southern pine exposed to natural weathering. Small blocks were removed from southern pine samples treated with CA and also southern pine treated with ACQ and MCA. Small blocks were also removed from ACQ-treated boards (flat and p...

Exploring bio-based chemicals in the residual stream from the thermal wood modification process
2024 - IRG/WP 24-30799
Numerous chemical-free processes have emerged in the wood processing industry to enhance the durability and optimize the service life of wooden elements exposed to exterior conditions. One such method, the hygrothermolytic modification process, patented as FirmoLin®, represents an industrial treatment for thermal modification of wood. This involves subjecting solid wood to a pressurized unsaturat...

Manufacturing of bamboo hybrids with high strength, superior fire retardancy, and dimensional stability
2024 - IRG/WP 24-30808
Bamboo, renowned for its rapid growth, high strength-to-weight ratio, and eco-friendly attributes, has found extensive use in decorative building materials and glue-laminated beams. However, the inherent challenges of dimensional instability and flammability in natural bamboo restrict its broad application. This research introduces a range of environmentally friendly techniques aimed at producing ...

Bio-durability and weathering performances of cardanol-treated wood
2024 - IRG/WP 24-30809
Cardanol is an excellent insecticide, fungicide, and termiticide derived from thermally treated cashew nutshell liquid (CNSL) and has been extensively explored in the chemical industry and for medicinal uses. However, its potential for wood protection remains unexplored. This study aims to understand the bio-durability and weathering properties of cardanol-treated wood. The southern pine and yello...

Durability of Malaysian plybamboo to mold
2024 - IRG/WP 24-41014
Durability of 3-layer plybamboo fabricated from two Malaysian bamboo species, Gigantochloa levis (beting) and Gigantochloa scortechinii (semantan) using three different adhesives - urea formaldehyde (UF), melamine urea formaldehyde (MUF) and phenol resorcinal formaldehyde (PRF) was evaluated in this study. Samples were exposed to the mold, Aspergillus brasiliensis for 4-week following the ASTM D44...

Bio-based thermal insulation panels – a way of cascading utilization of post-consumer wood
2024 - IRG/WP 24-50388
Cascading wood utilization is critical to fulfilling a circular economy frame in the wood industry. The work's aim was to apply wood dust from plywood production to the production of innovative bio-based thermal insulation panels. Trametes hirsute fungus was used as a composite binder, and then a composite structure and thermal insulation properties, water absorbability, and strength properties of...
