Research on gaseous COS degradation by brown-rot fungus Gloeophyllum trabeum
2024 - IRG/WP 24-11033
Physiological studies of wood rotting fungi have mostly focused on the metabolism of carbon and nitrogen sources, which constitute the dominants components of wood. On the other hand, despite the physiological importance of trace elements such as sulfur, studies on their acquisition sources and metabolic pathways are limited. Until now, wood rotting fungi have been thought to utilize slight amount...

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...

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...

Properties of thermal modified wood of Pinus pinaster, Pinus radiata and Pinus sylvestris from Galicia, Spain
2024 - IRG/WP 24-30800
This paper provides the results of a research about the properties of thermal modified wood of maritime pine (Pinus pinaster Ait.), radiata pine (Pinus radiata D. Don) and Scots pine (Pinus sylvestris L.) from Galicia, Spain, thermal treated in the industrial vacuum-heat autoclave plant of FINSA group in Galicia, Spain. These three pine wood species are used in different solid products but due the...

Natural weathering of modified pine and Eucalyptus woods by surface charring
2024 - IRG/WP 24-30801
Within various wood modification techniques, surface charring is anticipated to extend the lifespan of wooden components in building facades; however, visual deterioration of charred cladding materials has become a notable concern. This study, conducted through international collaboration, aimed to assess the resistance of bio-based facade materials to weathering in the Turkish climate. The natura...

Developing thermal-energy storage systems based on Kraft lignin-glyoxal and organic phase-change material modified wood
2024 - IRG/WP 24-30810
This study investigated the use of modified wood as a thermal-energy storage material through the integration of paraffin-based phase-change materials (PCMs). The objective was to evaluate the influence of Kraft lignin-glyoxal prepolymer on the properties of wood modified with PCMs. The implementation of the modified wood involved preparing PCM emulsions, synthesizing lignin-glyoxal prepolymer, an...

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...
