Pulp production from wood is one of the most central processes for producing renewable raw materials that can replace fossil resources such as petroleum. To enhance the role of the forest industry as a carbon sink, it is crucial to reduce carbon dioxide emissions from pulp production. One promising strategy to achieve this is to […]

This PhD project aims to identify and quantify the key factors that influence adhesive strength in bio-based adhesive systems. It focuses on understanding how adhesive chemistry, wood surface characteristics, and bonding conditions interact to affect both strength and durability. The research combines mechanical testing methods, such as tensile shear and compressive Strength, with material characterization

The goal of the experiment is to study interactions between bio-based adhesives (based on lignin-starch) and porous substrates (wood, paper). X-ray Computed Tomography (nXCT) of specimens of thicknesses 50 μm with a bond line of 2 μm-thin will be used to study adhesive penetration at multiscale levels in relation to (surface and interfacial adhesion, porous
Bond strength is commonly used today as the primary measure of a glued product’s ultimate failure characteristics. While it is essential for ensuring product performance, bond strength alone is not sufficient to define most other properties. Once an adequate level of bond strength is achieved, characteristics such as bond stiffness, Fracture Toughness and other interfacial

This project is part of the BioGlue Centre (https://www.slu.se/en/departments/forest-biomaterials-technology/bioglue-centre/), which is a co-operation between three universities and many industries aiming to have a better understanding around adhesives and bonding for wood materials in different sectors, such as furniture, construction, and packaging. In this project specifically, the aim is to map suitable and available bio-based raw

Heterogeneity is one of the fundamental scientific and technological challenges of all bio-based materials. The research area of NeoPulp is pulping and papermaking processes. We plan to study the heterogeneity between fibres that affects both process performance and the properties of current and new fibre-based materials. This is a largely unexplored research area where the
