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...

Prevention of termite tubing on foam insulation materials
2024 - IRG/WP 24-11039
Foam insulation products have been shown to be damaged by termites who can readily tunnel within it and use it as a conduit within structures. Different types of commercially available foam insulation were tested to see if they could support termite (Coptotermes formosanus, Shiraki) tunnelling on or within them and whether they could be used as a conduit to access a wood food source placed above i...

Investigating moisture dynamics and fungal decay risk: integrating X-ray CT visualization and simulation benchmarks through a Fungal Control Unit
2024 - IRG/WP 24-11045
Wood is susceptible to fungal attack and over time the structural integrity can be compromised. This risk is of course strongly related to moisture dynamics, as moisture is needed for fungal growth. While existing methodologies, such as lab and field tests, provide valuable insights into wood decay, they often fall short in replicating real-life conditions, particularly within the intricacies of t...

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 ...

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...

EMC as a quality control parameter for thermally modified wood
2024 - IRG/WP 24-20720
While standards for quality performance of treated wood have been in place for many years, none have been developed for modified wood such as thermally modified wood (TMW). Only in one case has TMW been listed in 2018, by the Nordic Wood Preservation Council (NWPC).
A key component of a quality system is its control parameters, i.e. the metrics that are to be measured and controlled. Existing m...

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...
