12. The influence of fibre characteristics on bulk and strength properties of TMP and CTMP from spruce
Sammanfattning : This thesis is intended to contribute to an increased knowledge about the influence of fibre characteristics on bulk and strength properties of thermomechanical pulp (TMP) and chemithermomechanical pulp (CTMP) from spruce. It deals with laboratory sheet properties and how they are affected by the conditions during pressing and drying, e.g. LÄS MER
13. Production and application of fine fractions made of chemical pulp for enhanced paperboard strength
Sammanfattning : For all kinds of paperboard packages, the bending stiffness of the paperboard is a crucial property. In multi-ply folding boxboard (FBB) grades, this is obtained by placing different stocks in the outer and centre plies of the board. In the outer plies, a stock with a high tensile stiffness is used, typically made from refined kraft pulp fibres. LÄS MER
14. Anaerobic Digestion of Wastewaters from Pulp and Paper Mills : A Substantial Source for Biomethane Production in Sweden
Sammanfattning : The Swedish pulp and paper industry is the third largest exporter of pulp and paper products worldwide. It is a highly energy-demanding and water-utilising industry, which generates large volumes of wastewater rich in organic material. LÄS MER
15. Mechanical Pulp Based Nano-ligno-cellulose : Production, Characterisation and their Effect on Paper Properties
Sammanfattning : Almost all research on biorefinery concepts are based on chemical pulping processes and ways of utilising lignin, hemicelluloses and extractives as well as a part of the remaining cellulose for production of nano materials in order to create more valuable products than today. Within the Forest as a Resource (FORE) research program at FSCN we are utilising the whole chain of unit processes from forestry to final products as paper and board, where the pulping process research focus on high yield process as TMP and CTMP.
