Electroactive Cellulose Composites Towards Future Green Devices
In the last few decades, significant interest has arisen in the use of cellulose in conjunction with electrically conductive materials for a wide range of applications, from energy storage and actuators to sensors. The primary driving force for selecting cellulosic materials stems from their intrinsic and extrinsic properties, such as high flexibility, processability, chemical stability, […]
Återanvändning av matavfall för att konstruera svampmembran och filter för vatten- och luftrening
Filter och membran är halvgenomsläppliga barriärer, som ofta produceras från fossilbaserade polymerer och används för luft- och vattenrening. Membranfiltreringsanläggningar drabbas av omfattande membranbeläggningar, vilket kräver frekvent membranbyte. Detta medför en stor mängd plastavfall. Å andra sidan, har coronapandemin lett till en dramatisk ökning engångsmasker och flera miljarder masker slängs varje dag. Miljövänliga alternativ krävs för […]
Improved uniformity of the fibers liberated in the kraft pulp digester
This project sets out to elucidate mass transport characteristics during delignification of wood chips as a means of understanding and controlling non-uniform delignification effects, associated to low efficiency and poor property control in the current pulping processes. To obtain information on local variations of delignification effect in a wood chip, the treated chips will be […]
Soft highly swelling fibres by alkali-activated chemical modification
To make cellulose fibres more flexible and malleable, components inside the fibre must be properly modified, that is, the lignin, hemicellulose or cellulose needs to be at least partly transformed into a proper derivative. Several cellulose derivatives are today produced through chemical reactions that involves formation of ether bonds. To reach sufficient efficiency, these reactions […]

Development of thermoplastic lignocellulose based materials
The aim of this project is to develop and increase the knowledge of thermoplastic materials from bleached pulp through minimal chemical modification.
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 […]
Efficient Washing of Paper grade pulp in the kraft process
The project contributes to strengthened Swedish competitiveness through its expected research results and new fundamental knowledge for the development of an efficient pulp washing process and thus through an increased pace of innovation in the transition to a circular economy. After pulping the wood chips, the resulting pulp fibres and cooking liquor are separated in a […]
EcinRaw – Electroactive carbon fibers for intelligent recycling of raw materials
The project aims to improve the current wastewater treatment methods by innovative strategies to handle metal-containing water streams, for efficient recovery of critical raw materials (CRM). https://www.vinnova.se/en/p/electroactive-carbon-fibers-for-intelligent-recycling-of-raw-materials/
Characterisation and effects of micro- and nanoscale components and their impact on efficiency of chemical additives
The project’s focus is on developing a methodology that will provide new knowledge and processcontrol capabilities concerning nano- and microscale fibrillar wood-pulp material in thepapermaking process.
Real time 4D X-ray microtomography Imaging and analysis of water transport mechanisms in sustainable paper straws
At present, there are no quantitative experimental studies for liquid transport with relevant spatial and temporal resolution in cellulose fiber networks. This project aims to improve the understanding of the dynamic interplay between water transport processes and the cellulose fiber network. In this way, the proportion of sorption of water in pores and cell walls […]
