Evaluation of the efficacy of silver nanoparticles and chitosan oligomer composites as poplar wood protective treatments against termites
2023 - IRG/WP 23-40963
Populus × euramericana ‘I-214’ (poplar) is a fast-growing species widely distributed throughout the world, and in the Castile-Leon region of Spain it accounts for more than 50% of all plantations. Its wood is becoming increasingly appreciated, yet its low durability against xylophagous agents —termites being one of the most aggressive and destructive in warm climates— continues to be a li...

Investigating the fire properties of a composite material made of MDF-residues, citric acid and sorbitol
2023 - IRG/WP 23-40969
In times of climate change and a shortage of energy and raw materials, it has become apparent, that material reuse of wood in a cascade system can reduce the ecological impact of a material and be cost effective. A new composite material has been developed made from citric acid, sorbitol, water and waste MDF. Not only will there be a material reuse option for waste MDF but due to the small particl...

Preliminary investigation of the durability and performance of 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) treated aspen strandboard
2024 - IRG/WP 24-30804
Wood modification technologies are growing in popularity because of their potential to improve wood properties by permanent covalent chemical modifications rather than chemical impregnation. These features can be utilized in wood composites to help improve dimensional stability and composite resistance to fungal decay. In this study, 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU) was used to m...

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...

Biofabrication of composite materials – Utilizing lignocellulosic biomass and mycelium in 3D printing
2024 - IRG/WP 24-50396
In this research, we investigated the potential of utilising lignocellulosic biomass and mycelium for 3D printing applications to develop sustainable biocomposite materials. Our study began with a systematic investigation of various fungal cultures, including Pleurotus ostreatus, Schizophyllum commune, Ganoderma resinaceum, Trametes versicolor and Gloeophyllum trabeum, in combination with substrat...
