    WoodPro creates sustainable value addition from forest residues

    Bio-based resources from well managed forests play important roles in transition to a sustainable society. In WoodPro, the research team will explore new processing chains that convert forest residues to high-value industrial chemicals and soil amendment products.

    - WoodPro is an EU cooperation in form of a consortium with three sub-projects hosted in Karlstad University, the Natural Resources Institute in Finland (LUKE) and the University of Eastern Finland (UEF). Many industrial partners in Sweden and Finland, both large industries and small and medium sized enterprises, have expressed an interest to collaborate within WoodPro, says Ali Mohammadi, senior lecturer in environmental and energy systems, and the consortium leader.

    Research on sustainable papermaking

    Karlstad University has been granted funds from the Knowledge Foundation, for conducting research on energy-efficient tissue manufacturing, in collaboration with the paper industry. The aim of this research project is to reinforce Sweden’s competitiveness and to contribute to a sustainable development.

    – We look forward to starting this research project in collaboration with the industry, where we combine laboratory studies, pilot trials and modelling, says Björn Sjöstrand, senior lecturer in Chemical Engineering and the research project leader. It’s a collaboration between researchers at Karlstad University and the companies Valmet and Albany International.

    Research on virtual paper machine receives award

    Björn Sjöstrand, senior lecturer in Chemical Engineering, has been awarded the Heinzel-Mondi-Sappi Award for his research on the virtual paper machine. His research makes it possible to optimise and test the manufacturing process in the industry, without expensive production stoppages.

    “The award was given out at the Paper & Biorefinery conference in Graz in Austria,” says Björn Sjöstrand. “I received the award for my article ‘Numerical model of water removal and air penetration’, about models for vacuum-based water removal.”

    Welcome, Rainey Lyons

    Rainey Lyons has joined Karlstad University and the mathematics department. Rainey has previously worked for University of Louisiana at Lafayette, USA, where he worked in a subfield of mathematical biology looking at structured population dynamics set in a space of Radon measures.

    - I was changing the setting of which we do this modelling to a more abstract object than a function, says Rainey Lyons. The structured populations are modeling a population where we care about some kind of structure – the individual´s age or size for example. This is actually used currently by biologist working with trees. A trees size is very important because if it´s taller than the other trees it can get more sunlight and therefore can be more competitive.

    Research contributing to increased recycling

    Björn Sjöstrand, Senior Lecturer in Chemical Engineering at Karlstad University, was awarded the Young Researcher’s Award 2022 at Forum for Bioeconomy. Björn Sjöstrand’s research aims to create new insights into hornification – a research area with the potential of providing more opportunities for the forest industry to understand the changes in the wood fibres’ capacity to forming strong networks.

    - Hornification occurs when the cellulose in the fibre bind to other cellulose chains within the same fibre, says Björn Sjöstrand. This prevents the fibre from swelling and reduces their flexibility. Flexible fibres are important for strength properties when manufacturing cardboard and paper.

    Chemistry experiments under microgravity condition

    Solar cell researchers from Karlstad University have once again conducted experiments in zero gravity during parabolic flights in Bordeaux, France. The aim is to study how the structure of the active layer of the polymer solar cell is formed, to thereby be able to increase its efficiency.

    – This is the second time we have conducted experiments during parabolic flights, says Jan van Stam, Professor of Physical Chemistry at Karlstad University. We are studying the transition from solution to thin, solid film that constitutes the active layer of the solar cell, where the sunlight is converted into electricity. When you remove gravity, structure formation slows down. This makes it possible for us to, in more detail, study how the structure of the material changes.
