TreeGlue: fully wood-based adhesives for sustainable wood composite

This project aims to develop high-performance bio-based adhesives from lignin, a renewable and abundant biomass resource. The research focuses on developing a green and mild demethylation strategy to convert methoxy groups in lignin into phenolic hydroxyl groups. This modification is expected to significantly enhance the reactivity of lignin, thereby promoting crosslinking reactions and leading to […]

Enzymatic functionalization of hemicellulose to produce biobased cross-linkers

The overall aim of this project is to enzymatically modify glycans from hemicellulose to produce bio-based cross-linkers for applications in adhesives, hydrogels and other cross-linked materials. Many materials that we consider as bio-based such as wood fibreboards, hydrogels and stabilizers from non-fossil polymers are still dependent on cross-linkers that are of fossil origin and often

Diffusion and damage during delignification of wood biomass (D4mass)

Delignification is a crucial process in the pulp industry that separates lignin and cellulose, the two biobased raw materials with enormous potential. During this process, the removal of lignin through diffusion is coupled with the accumulation of damage in cell walls, causing cracks and changing the trajectory of diffusion. However, a mechanistic understanding and a

Exploring Cellulose in the design and synthesis of covalent adaptable networks: a route towards recyclable and sustainable thermosets

Thermosets are known for their poor (re-)processing and recycling capabilities due to theirpermanently crosslinked microstructure. As a result, their end-of-life options are limited to landfill orincineration, preventing thermosetting materials from meeting the demand for sustainable andcircular materials. In recent years, the introduction of dynamic covalent bonds in polymeric networkshas formed a promising solution to the

Recycled, renewable and reprocessable insulation foams

Efficient insulating foams are crucial as building materials as they reduce the energy consumption for heating, but currently polymeric foams are predominantly made from fossil-based resources with linear waste streams making them unsustainable. In order to deal with these challenges, the goal with this project is to develop recyclable polymeric insulating foams that stem from

Circular, scalable, multifunctional wood aerogel 

Aerogels are attractive in various applications ranging from aerospace to energy storage due to low density and high specific surface area. Mainstream strategy to obtain lignocellulosic aerogels is bottom-up approach, disintegrating wood into nano building blocks (e.g. nanocellulose) followed by reassembling into aerogels. The complex and/or energy intensive processing are challenges. Top-down approach is an
