The project aim is the design and engineering of biomass-derived composites to substitute petroleum-based materials.
The aim of my project is to create a scientific base for sustainable processes for using the waste-residue streams from pulp production more efficiently.
In this project vi use molecular dynamics (MD) simulations to investigate hygroscopic properties of various lignins. Our hope is that structure and dynamics on the atomistic level of details will complement existing macromechanical models. The goal is to test existing atomistic models of lignin subject to its interactions with water. The output of the project
Laboratory X-ray tube-based microscopic computed tomography (XµCT) aided finite element (FE) modelling considers XµCT data to characterize key engineering properties needed for modelling of material behavior. The method includes steps such as XµCT scanning, segmentation, meshing, and fiber reconstruction and can be supported by techniques such as digital image correlation and digital volume correlation. At
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
The current and future environmental challenges call for improved and more sustainable processes in the pulp industry. To contribute to a sustainable and competitive Swedish bioeconomy the pulp industry needs to increase efficiency without increasing the use of hazardous chemicals. Oxygen delignification is a unit process that has been used in pulp mill fiberlines between
The kraft process is today the dominant industrial technology for the production of pulp from wood.In this process, wood chips are boiled with chemicals in order to dissolve lignin, hemicellulose andextractives. The process itself contains several complex mass transport mechanisms, where thechemicals are to be transported into the wood chip and then further into the
The use of wood as a building material because of its efficiency, sustainability, and durability is increasing. Wood is a renewable resource, it has low carbon impact and low embodied energy. The amount of energy needed for producing wood products is much less than comparable products made from other materials. In spite of its common
