Chemical modification of cellulose nanofibrils for tailoring properties of composites
2022 - IRG/WP 22-40934
Due to its natural abundance, complete biodegradability and excellent properties, cellulose is one of the most promising materials for the production of bio composites, as well as one of the most promising fillers for biodegradable polymer composites. This is also true for nanocellulose. A large number of hydroxyl groups on the surface of fibers or fibrils enables a whole series of chemical reacti...

Reuse of discarded wood and alternative wood species to replace spruce in the development of wooden windows for complete disassembly – REWINNUSE
2023 - IRG/WP 23-30785
The REWINNUSE project focuses on the reuse of discarded wood and alternative wood species and on the development of wooden windows that can be easily disassembled into their basic components. In cooperation with the project partners (M Sora, the University of Ljubljana Biotechnical Faculty (BF), the Norwegian Institute of Bioeconomy - NIBIO and the Slovenian Forestry Institute (GIS)), the project ...

Analysis and performance of spruce alternative species and discarded wood for windows production
2024 - IRG/WP 24-50386
Climate change is having a significant impact on European forestry, particularly on the softwood species used for window frames. This study investigates potential replacement tree species for spruce (Picea abies), the predominant material for window frames. We evaluate Douglas fir (Pseudotsuga menziesii), Scots pine (Pinus sylvestris), thermally modified poplar (Populus nigra) and discarded silver...

The durability and mechanical properties of 40 years old Black locust poles
2024 - IRG/WP 24-11042
This study investigates the durability and mechanical properties of 40-year-old black locust (Robinia pseudoacacia) poles harvested from a vineyard in Slovenia. Wood from these poles was compared to recently harvested black locust wood to determine possible reuse options. Visual inspection, hyperspectral imaging, and laboratory tests were conducted to assess decay, density, mechanical properties, ...
