    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.

    Why Mangroves are declining globally

    Mangroves can thrive in harsh environment and are used to natural perturbations like tropical cyclones. But, with several confounding pressures exacerbating each other, mangroves fail to withstand and diminish.

    Mangroves, the coastal cousins of the inland forests, do not only represent a unique set of rich biodiversity but also provide important livelihoods, coastal defence, and carbon sinks. Yet despite their critical importance, mangrove forests sized the entire Tokyo city (8,600 km2) disappeared during the last three decades. South and Southeast Asian region encountered the highest loss with Indonesia topping the countries.

    Exponential climate action by diverse actors is key

    Researchers Avit Bhowmik and Sol Agin comment on the latest report from The Intergovernmental Panel on Climate Change (IPCC).

    For the very first time, IPCC explicitly recognized and emphasized the role of diverse non-state and subnational actors in climate action. Starting at the very first page of the report, the importance of distributed and diverse climate action projects and multilevel and polycentric climate governance for sustaining the reductions in greenhouse gas (GHG) emissions was highlighted throughout the report and particularly in section 14.5.

    Research that facilitates safe and sustainable online shopping

    What barriers do consumers face on the digital market place, and how can these be counteracted? In a project with the Swedish Consumer Agency, researchers at CTF, Service Research Center at Karlstad University, have examined this issue. The research findings are now used in an information campaign directed at consumers.

    In 2020, the Swedish Consumer Agency was tasked by the Swedish Government to identify and analyse barriers to well-functioning consumer markets and sustainable consumption. Part of the assignment was to identify pros and cons with different types of measures to combat these barriers.

    Research projects to localise Sámi walking trails

    The forced displacement of Sámi people in the early 20th century is an unknown subject for many. Richard Ek has been granted research funding to use digital technology to localise the walking trails and develop them into tourist destinations.

    The project is called Sámi Trail of Tears Walking Trail, and aims to examine and prepare walking trail through Northern Sweden’s interior, that will follow the geographical route the displaced Sámi were forced to take in the early 20th century.
