Biomass fractionation: chemical pulping refineries and novel fractionation processes
We investigate radically new energy and resource efficient production technologiesfor chemical pulping, e.g. Kraft-Oxygen Delignification (KrOxy) process and new dissolving pulp technologies. In addition, our research group develops novel biomass fractionation processes based on the utilization of supercritical water and green solvents, e.g. gamma-valerolactone (GVL).
Cellulose: We study conversion of cellulose e.g. into man-made cellulose fibers and all-cellulose composites.
Hemicelluloses: Our research topics include the valorisation of xylan from alkaline extractions, production of xylo-oligosaccharides and catalytic conversion of biomass-derived sugars into furans.
Lignin: Lignin is an interesting biomass component which can be converted into valuable products such as bio-oil. Lignin-cellulose blends can be used e.g. as precursor fibers for carbon fibers, or as natural dye in textiles.
ALL-CELL: From ultra-light to ultra-strong all-cellulose composites via green processing
Finland Distinguished Professor grant awarded to Prof. Tatiana Budtova (Center for Materials Forming of MINES ParisTech, France). The goal of the 4-year project (started 2016) is to imagine, prepare and characterize new fully bio-based materials, all-cellulose composites.
Ioncell-F is a technology that turns used textiles, pulp or even old newspapers into new textile fibers sustainably and without harmful chemicals. The process converts cellulose into fibers which in turn can be made into long-lasting fabrics.
