Environmentally Friendly Wood Modification based on Tannin-Furfuryl alcohol - Effect on stabilisation, mechanical properties and decay durability
2022 - IRG/WP 22-40929
Furfurylation is a well-known wood modification technology. This paper studied the effect of tannin addition on the wood furfurylation. Three kinds of dicarboxylic acids, adipic acid, succinic acid, and tartaric acid, as well as glyoxal as a comparing agent, were used to catalyse the polymerisation of furanic or tannin-furanic solutions during wood modification. Impregnation of furanic or tannin-f...

Improving wood durability by mineralisation and thermal modification
2022 - IRG/WP 22-40948
A significant increase in the fungal durability of wood was achieved by using a modification procedure combining two environmentally friendly methods: thermal modification and mineralisation. It offers an ecological alternative to other biocidal treatments. European beech (Fagus sylvatica) and Norway spruce (Picea abies) were selected as model wood species and exposed to four different fungi: Gloe...

The spread of technology in a simple wooden pile construction method to prevent shallow landslides
2025 - IRG/WP 25-20733
This study introduces the development and practical application of an innovative slope stabilization technique called the Wood Pile Root System Method (WPRSM), aimed at preventing shallow landslides, which have increased due to the rising occurrence of extreme weather events caused by climate change. This method effectively reinforces slopes using thinned timber, providing a sustainable and cost-e...

Sustainable and environmentally friendly bio-based protection against fire
2025 - IRG/WP 25-20756
Flame-retardant agents are used to confer fire resistant properties with effects strongly dependent on their ability to form char during the thermal degradation. The char coats the polymeric materials and provides a good barrier against heat and oxygen diffusion, thus reducing the combustion rate of the polymeric materials. Halogenated agents that are used today are toxic and may cause severe heal...

Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
New mineral-wood composites that demonstrate improved fire properties and higher resistance to selected fungi have been prepared using an environmentally-friendly mineralisation process involving impregnation with an aqueous magnesium acetoacetate solution. MgCO3-based compounds are formed in situ, deep within the wood’s structure. We show that the new mineralisation method overcomes wood’s lo...
