1. Microfibrillated cellulose : Energy-efficient preparation techniques and key properties
Abstract : This work describes three alternative processes for producing microfibrillated cellulose (MFC) in which pulp fibres are first pre-treated and then homogenized using a high-pressure homogenizer. In one process, fibre cell wall delamination was facilitated with a combined enzymatic and mechanical pre-treatment. READ MORE

2. Microfibrillated cellulose: Energy-efficient preparation techniques and applications in paper
Abstract : This work describes three alternative processes for producing microfibrillated cellulose (MFC; also referred to as cellulose nanofibrils, CNF) in which bleached pulp fibres are first pretreated and then homogenized using a high-pressure homogenizer. In one process, fibre cell wall delamination was facilitated by a combined enzymatic and mechanical pretreatment. READ MORE

3. Dissolving pulp : Multivariate Characterisation and Analysis of Reactivity and Spectroscopic Properties
Abstract : Various chemical properties can be used to characterise dissolving pulp. The quality of the pulp must be carefully controlled to ensure that it meets the requirements for its intended use and the further processes to be applied. READ MORE

4. Mechanical Pulp-Based Nanocellulose : Processing and applications relating to paper and paperboard, composite films, and foams
Abstract : This thesis deals with processing of nanocellulose originating from pulps, with focus on mechanical pulp fibres and fines fractions. The nanocellulose materials produced within this research project were tested for different purposes ranging from strength additives in paper and paperboard products, via composite films to foam materials.

5. Dissolution of cellulose for textile fibre applications
Abstract : This thesis forms part of a project with the objective of developing and implementing a novel, wood-based, process for the industrial production of cellulose textile fibres. This new process should not only be cost effective but also have far less environmental impact then current processes. READ MORE
