Processing of organosolv fractions for a functionalization and valorization in biobased materials

Optimization of organosolv wood fractioning is performed to obtain pulp containing cellulose, hemicellulose, andlow levels of lignin. The pulp is functionalized to achieve specific fibre properties, such as water stability. The functionalized fibres are evaluated in industrial partners’ products, i.e. biobased foams, to provide valuable feedback for optimization of the functionalization procedures based on industry …

This project is about development of novel wound dressing materials and we are making cellulose nanofiber hydrogels from wood as raw material.

Multiscale carbonized lignin nanomaterials with tailored structure for high electrochemical capacitance

The project work focuses on the development of functional nanostructured carbon material with large specific surface area and derived from sustainable materials, mainly lignin. Approaches such as electrospinning, freeze-casting as well as 3D printing can be involved. The possible applications of the carbon material can be electrodes in high-performance energy storage devices, for example, supercapacitors.

KAW Biocomposites

Technical objective The project is focused on materials design of biocomposites which are semi-structural, recyclable and/or biodegradable. The term “semi-structural” needs to be defined. If 30wt% glass fiber/polypropylene is selected as the reference material for substitution, it would mean that the modulus should be > 6 GPa and the tensile strength > 85 MPa. In …
