Improved Separation of Wood Components for Resource Efficient Biorefineries

This research addresses the alkali-induced degradation of polysaccharides which is a fundamental problem in wood pulping. By stabilizing the reducing end groups of these polysaccharides, we aim to preserve more of the valuable carbohydrate content and enhancing resource efficiency. The project contributes both to mechanistic understanding of carbohydrate degradation and to applied innovation in wood […]

Improved uniformity of the fibers liberated in the kraft pulp digester 

This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be

Functionalized cellulose structures from aqueous alkaline systems

Even though aqueous alkaline systems are among the most prominent and sustainable conversion media for cellulose (of particular importance for large scale processes) fundamental understanding of principal molecular interactions in these systems is still limited, especially of those stabilizing cellulose solutions in aqueous alkali.   However, regardless of the nature of stabilizing interactions in these solutions,

Turning the cold NaOH(aq) into a powerful processing system for cellulose by utilizing its abundance of CO2 – a step towards sustainable textile processes

Today, there is an urge to meet the increased textile consumption by wood- and recycled cellulose textiles, based on new sustainable dissolution concepts for cellulose. Still, there are only few solvents capable of dissolving the intricate cellulose structure while being environmentally friendly and industrially viable. One of them, experiencing a renewed interest is undoubtedly cold
