Multi scale modeling of the delignification kinetics during kraft cooking

The kraft process is today the dominant industrial technology for the production of pulp from wood.In this process, wood chips are boiled with chemicals in order to dissolve lignin, hemicellulose andextractives. The process itself contains several complex mass transport mechanisms, where thechemicals are to be transported into the wood chip and then further into the […]

Polysaccharide Monooxygenases (LPMOs) for Advanced Nanocellulose Materials

LPMOs (lytic polysaccharide monooxygenases) are oxidative enzymes that enhance cellulose fibrillation by introducing charged carboxyl groups onto the cellulose surfaces in aqueous reaction conditions. The use of LPMOs in production of nanocelluloses could reduce the need of hazardous chemicals and facilitate more environmentally friendly processes. The aim of this subproject is to produce recombinant LPMOs

Assessment of the homogeneity of chemical modifications aimed for thermoplasticisation of cellulosic fibres

The strong driving force behind the sustainable biomaterial-based society is to replace the fossil fuel-based materials with renewable resources to for example address the climate change. Thermoplastic polymer products are used on a daily bases in every household and they need to possess the properties such as being ductile and formable. However, cellulosic materials do

Bio-based binders for molded cellulose fibers

Natural binders are inexpensive, biodegradable, environmentally friendly and renewable, but usually form weaker bonds and slightly harder to apply. The objective of the project is to develop and optimize the process of using various plant polysaccharides as binder for holocellulose fibers and cellulose nanofibrils (CNF). The selected polysaccharides are further functionalized to improve interfacial adhesion

A new sustainable route to polysaccharide hydrogel formation for medical and cosmetic applications

Hydrogels are an extremely versatile class of material, and have found relevance in cosmetic, medical, pharmaceutical, and industrial processes. A hydrogel has a low solid content, often comprising at least 90% water. Although hydrogels are increasingly used in cosmetics and drug manufacture, the production process is far from sustainable, relying on fossil-based polymers and chemical

Self-assembly of 2D nanoflakes by using 1D cellulose nanofibrils

The earth-abundant 1D cellulose nanofibrils (CNFs) have shown the capacity to assemble different functional nanoparticles into 2D films and 3D foams. 2D nanomaterials such as MXene, graphene, transitional metal dichalcogenides (MoS2, WS2, etc.) are the ones of most promising functional materials in optical, electronic, and magnetic fields. We are using the 1D CNF to align

Renewable High-Performance Materials from the Forest with Designed Degradation – Next Generation of Plastic (Re-Design Plastic)

Sustainable material design can alleviate the environmental burden related to material waste. Use of available and abundant resources, create materials that can be recycled, and final degradability in nature is central to achieve this. The overarching aim of the proposal is to holistically design new materials from cellulose fibers by; developing new sustainable modification strategies,
