This project focuses on one of the most basic questions within the topic of fire retarded (FR) treated wood; “how we can actually measure the concentration of FR in wood specimens”, this seems like a trivial question, but is actually a significant issue, barrier to further research studies, and more wide spread usage of wood …

The development of catalysts to upgrade renewable feedstocks is vital for a sustainable future. Alternative feedstocks typically differ in chemical composition compared to fossil-based feedstocks and to further develop catalytic materials that enable efficient and environmentally friendly chemical processes, it is necessary to understand the functional mechanisms of these materials in detail.The high oxygen content …

Compacted paper laminates can be formed by deep-drawing or press-forming to produce packaging solutions with height to diameter ratios not reachable with conventional thermoforming machines. These processes involve complex interactions of the fibres in the compacted paper layers and between these layers, including the bonding between them, which can be made either with glue or …
Modern produktutveckling är till allt större del virtuell vilket innebär att datormodeller används för att förutspå en förpacknings beteende innan den existerar fysiskt. Fördelen med att använda datormodeller är att produktutvecklarna kan pröva nya ideer och koncept virtuellt utan att tillverka dyra fysiska verktyg samt att ledtiden från ide till produkt kan kortas avsevärt. Vidare …
Den globala efterfrågan på textilfibrer ökar kraftigt, samtidigt som världens bomullsproduktion har stagnerat bland annat p.g.a. konkurrens om den odlingsbara arealen. Bomullsproduktion medför dessutom en stor belastning på miljön, och det finns starka incitament att ersätta både bomull, och den oljebaserade polyesterfibern, med ett mera miljövänligt och långsiktigt hållbart alternativ såsom cellulosa från trä. Idén …

The project involves the development of new experimental methods to characterize deformation processes in fiber-based materials, in particular paperboard. The experiments are to be performed on several scales, from micro to macro, and aim to increase understanding of the mechanisms that control the mechanical properties and behaviour of the material. Experimental devices that can be …
The use of wood and wood based materials in moist environments is limited because of these material’s susceptibility to decay fungi. The durability thus needs to be improved, which can be achieved by chemical wood modification. The exact mechanisms behind the increased durability of modified wood is however not known, but the lowered moisture content is …

Modern methods to protect wood from degradation aims at increasing the service life of the material by removing or reducing the cause of degradation: water within the material. This can be done by wood modification, e.g. acetylation or heat treatment. However, there is a lack of understanding of what happens within the wood, which hampers …
The project is focused on the chemical design and development of new monomeric building blocks from lignin and cellulose feedstocks. These building blocks mainly include different cyclic diols, diesters, diamines, etc, to prepare mechanically rigid and thermally stable bio-based thermoplastics for use as high-performance packaging and engineering plastics.
Reduction of fouling and efficient cleaning is of great importance for membrane processes to be successfully implemented in ligno-cellulosic biorefineries on an industrial scale. The key objective of this project is to develop real time methods to analyse fouling and cleaning plus new cleaning methods, e.g. enzymatic cleaning. Thus, the project aims to reduce water consumption, …

The project aims to develop experimental methods for characterizing packaging materials. In the project, the microstructure of packaging materials w ill be methodically characterized and linked to mechanical properties. Traditionally, mechanical testing of paperboard material has been carried out without regard to micro-level mechanisms. With new experimental methods such as in situ x-ray tomography, much …
We need to increase the use of lignocellulosic materials in all sectors in society, e.g., both as construction materials and as feedstock for the chemical industry. The possiblilty of such an increase is dependent on whether we can make construction materials more durable by eco-friendly methods, and the lignocellulosic feedstock easier to degrade in the …
