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...

Changes in decay risk of wood in ground contact over Europe, from analysis of historic climate conditions
2024 - IRG/WP 24-41008
Changing climate conditions will affect global temperature and precipitation patterns, shifting some geographical areas into states that are more suitable for fungal wood decay. Climate normals, which are taken over a 30-year period, capture vast spatial and temporal variations in these conditions and comparing these can show changes over time. Importantly, being able to identify locations that ha...

Phytosanitary treatment of roundwood for oversea shipping - on the suitability of dry heat treatment as alternative to climate-change effective fumigation
2024 - IRG/WP 24-50394
The transcontinental trade of roundwood requires thorough phytosanitary treatment to protect native flora and fauna against foreign pests. This is generally done by fumigating shipping containers packed with roundwood with sulfuryl fluoride, a potent greenhouse gas. After treatment, the gas is released into the atmosphere, causing massive emissions. Since 2017, the usage of sulfuryl fluoride in th...
