Molecular Basis of the Interactions and Recalcitrance of Lignocellulosic Biomass
Lignocellulosic biomass represents the main renewable resource from the biosphere for the production of biofuels, platform chemicals and bio-based materials. Lignocellulose consists of a complex polymeric network of cellulose microfibrils embedded in a matrix of hemicelluloses, pectins, and lignins with exquisite organization from the nano- to the microscale. However, the heterogeneity of the lignocellulose polymeric […]
Upscaling of natural plastic alternatives: towards a sustainable industry
The extensive use of fossil-based plastic around the world is accelerating climate change. The global life cycle GHG emissions of fossil-based plastics were 1.7 Gt of CO2 equivalent in 2015 and would reach 6.5 Gt CO2 equivalent by 2050 if the current plastic demand trend were to continue. However, legislations and consumers are pushing the […]
Colloidal properties of nanocellulose dispersions
The project aim is to control the stability and orientation of nanocellulose particles, by understanding the fundamental colloidal interactions between them in aqueous media. The information will then be used to create ordered and self-organized structures from nanocellulose dispersions. This knowledge is of great importance, since many nanocellulose based materials today are produced directly from […]
Circular cellulose to textile fiber production
The overall aim is to enable an upscaled process for textile fiber production based on alternative cellulose rich feedstocks together with TreeToTextile’s process, which is resource and energy-efficient without use of toxic chemicals. The proposed project focuses on the knowledge development for utilization of cellulose from residual streams, such as agricultural waste streams, recycled cartonboard/paper, […]
FibreFuse – Biobaserade kolfiber: Hur undviks att biobaserade kolfibrer fastnar i varandra under tillverkningen?
Att använda kolfibrer som armering i kompositer ger ett lättviktsmaterial som kan ersätta stål, aluminium eller glasfiber i många konstruktioner, t.ex. i fordonsindustrin eller till turbinbladen i vindkraftverk. Dessvärre är dagens kommersiella kolfibrer för dyra för många tillämpningar och även tillverkade av fossilbaserade polymerer. Lignin har länge ansetts vara en speciellt attraktiv kandidat som råmaterial […]
Conducting polymers-modified wood composites
In this project, we used different conducting polymers to impregnate the wood. Our goal is to create a pathway for studying the nano/microscopic structure of the conductive wood and the interactions between the wood components and the conducting polymer matrix. . In detail, we mainly focus on the difference of crystallinity and the orientation of […]
HEALIX
This project is about development of novel wound dressing materials and we are making cellulose nanofiber hydrogels from wood as raw material.
Ex situ and in situ advanced electron microscopy of enzymatic action for biomass tailoring and transport paths in conducting fibres and yarns
The structure of wood is complex with many components. As new cellulose-based materials and devices are to be developed and optimized it is crucial to understand the material microstructure of wood and also the properties of its individual microstructural constituents. Electron microscopy offers a unique capability for site specific imaging, diffraction and spectroscopy with high […]
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 […]
Hållbara isoleringsmaterial för efterisolering av byggnader
Projektets huvudsakliga syfte är att utveckla teknik som kan bidra till att förbättra energieffektiviteten i de stora hyreshus som byggdes på 1960- och 1970-talet och bidra till att uppnå detta på ett hållbart sätt. Ambitionen är att utveckla ett isoleringsmaterial som är 100% biobaserat och återvinningsbart via kartongåtervinningen och därmed bidra till omställningen till en […]
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 […]
