Wood hemicelluloses for surface modification of fibers, paper and boards

Project description:
SNS-97. The goal of this multidisciplinary project is to evaluate possibilities for conversion of hemicelluloses separated from forest sources as well as from waste steams from the pulp and fiber production into novel surface materials for fibrils, fibers and packaging materials. Hemicelluloses are the second most abundant polysaccharide after cellulose and they comprise about one third of wood material. However, compared with cellulose and starch, utilization of hemicelluloses has been mainly neglected. The future target is an increased utilization of this valuable material for example to replace some currently used oil based materials. The project will include experiments with different hemicelluloses samples, xylans and mannans, in order to evaluate their potentials for further development of applications. The results will provide valuable information for novel utilization of forest resources.
