Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...

Unlocking the Potential of Dairy Coproducts in Wood Modification
2025 - IRG/WP 25-30822
The production of dairy coproducts, such as whey (sweet or acid) and whey ultrafiltration permeate, has significantly increased in response to the rising global cheese consumption. Proteins found in by-products are purified for human nutrition. However, upcycling lactose, which is the major compound of cheese by-products, is more challenging due to the high cost of upcycling processes. Furthermore...
