Hyperlignification of wood is a novel wood protection technology that enables wood impregnation with highly concentrated lignin solutions (Thybring et al. 2024). The hyperlignified wood is shielded from moisture and decay fungi, enhancing durability while avoiding toxic biocides.
Lignin is a renewable and extremely abundant byproduct of paper production. In combination with biobased solvents such as water and bioethanol, the production of hyperlignified wood offers an attractive solution to achieve durability in local, low-value wood. This could potentially transform the outdoor wood market, which is actively seeking alternatives to environmentally harmful practices. While technological development is needed in the upscaling of the technology, this study investigates the potential impact of production of hyperlignified wood and tries to assess the scalability of the technology.
