Dr. Herbert Sixta studied chemistry at the University of Innsbruck, Austria, and obtained the PhD in 1982 with his work on the interaction of carbon dioxide, hydrogen and saturated hydrocarbons with Pt-, Ru-, Cu- and Ru/Cu-catalysts. He then moved to Lenzing AG, a leading company for the production of regenerated cellulose fibers, where he built up a research department mainly focused on pulp chemistry and technology (1987). After his habilitation in 1995 at the Technical University of Graz, Austria, he has been giving lectures on cellulose chemistry, pulping technology and chemistry at the universities of Graz, Linz and Vienna. At present, the scientific activities of Herbert Sixta are focused on the improvements of pulping technologies for the production of dissolving pulps including the recovery of value-added by-products derived from pulping and purification processes.
