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 ...

Suberinic acid from birch bark and its suitability in wood protection
2024 - IRG/WP 24-20708
This study investigated the effect of different concentrations of suberinic acid (SA) on the growth of two fungi species. Initial radial growth tests showed a slightly slower growth rate for brown rot, whereas white rot exhibited faster growth than the untreated reference. In contrast, a commercial wood preservative significantly reduced the radial growth of both fungi species. Evidence of cell wa...

Terpene-based latex synthesis for exterior wood protection
2024 - IRG/WP 24-20715
Driven by challenges in raw material supply chains, the coatings industry is actively seeking biobased alternatives to enhance outdoor wood protection. This study aims to investigate the integration of biobased monomers into latex formulations, aligning with protocols applicable in industrial contexts. A semi-batch emulsion polymerization protocol was developed, designed to be scalable and meet es...

Investigation on the use of whey ultrafiltration permeate as a biosourced agent of wood protection
2024 - IRG/WP 24-20718
The ever-growing demand for sustainable materials has driven research toward innovative strategies in both the fields of material science and environmental management. Wood is a natural composite that is attracting more and more attention due to its high physical strength, great machinability, aesthetic appeal, and low price as a renewable and biodegradable resource. It has a long-standing history...

Virtual reality of wood protection
2024 - IRG/WP 24-20727
Virtual reality (VR) is a technology that allows people to explore and interact with computer generated environments using devices that stimulate different senses (sight, sound and touch). VR is mainly used for education, training and entertainment, but it also has the potential to provide new insights into scientific phenomena. We describe our work on the use of VR as a learning tool for students...

A novel treatment for increasing UV stabuility of wood based on citric acid and urea
2024 - IRG/WP 24-30811
Wood, a fundamental material in the Built Environment, faces challenges related to durability and weathering, notably UV degradation leading to colour changes. This study explored a novel treatment method utilising citric acid and urea to enhance the UV stability of wood. The reaction between these compounds forms fluorescent species and insoluble nanoparticles upon thermal treatment. Two treatmen...
