Tall oil in combination with eugenol for wood protection
2023 - IRG/WP 23-30787
The aim of this study was to investigate the possibility to use tall oil in combination with eugenol for wood protection. The idea was that the eugenol would increase the decay resistance of the tall oil while the tall oil would decrease the leaching of the eugenol.
The results show that an impregnation liquid of 31,5% tall oil, 3% eugenol and 65,5% methanol increased decay resistance of pine sa...

Bio-inspired wood protection, modification and functionalization
2023 - IRG/WP 23-40989
Wood is a versatile, natural, and environmentally friendly resource that has attracted attention as a material for sustainable building for many years. Recent advances in materials research have delivered several innovative solutions for the construction sector. However, intrinsic properties of wood affects its operational durability, which is still a limiting factor in many applications and envir...

Evaluation of the effectiveness of soaking of high-temperature plywood in low-temperature oil-based wood
2023 - IRG/WP 23-40991
We conducted a preliminary investigation to determine if soaking high-temperature plywood in a low-temperature preservative solution could achieve deeper penetration of the preservative, even in plywood made with refractory wood species such as Japanese larch. Specimens cut from commercial plywood (Japanese larch) were stored at various temperatures before being soaked in the preservative solution...

A mini review on climate change impact on bio-ecology of subterranean termites
2023 - IRG/WP 23-50375
Climate change is creating possibilities of changes in the bio-ecology of termites across the globe. This change will be felt differently in different regions. While changes in swarming times will be common in the Northern hemisphere, the tropic will encounter more life-history related changes. But termites posing newer threats induced by climate change will be mostly dependent on human activitie...

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 ...

Enhancing UV resistance and decay resistance of wood by nanoparticle dispersed linseed oil nanoemulsion
2024 - IRG/WP 24-20706
Enhancing increasing demand for eco-friendly and cost-effective wood coatings and preservatives has led to the development of water-borne formulations and use of non-toxic and natural materials such as vegetable oils and waxes. The aim of this study was to improve the UV resistance and decay resistance of wood by nanomaterial dispersed linseed oil emulsions. Highly stable nanoemulsions of linseed ...

Potential of heartwood extracts as wood preservatives combined with linseed oil in 8-year above-ground and in-ground field trials
2024 - IRG/WP 24-20719
The current study assessed the efficacy of heartwood extracts from Tectona grandis, Dalbergia sissoo, Cedrus deodara, and Pinus roxburghii, combined with linseed oil, as protectants for two non-durable wood species against termites and decay fungi. Stakes measuring 45.7 × 1.9 × 1.9 cm and blocks measuring 12.5 × 3.75 × 2.5 cm of the sapwood of southern pine (Pinus sp.) and cottonwood (Populus ...

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...

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...

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...

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...
