Professor Emeritus Herbert Sixta: “The most important task of a professor is to educate young people, to help them build their career”

After an extensive career in academia and the forest-based industries, Professor Herbert Sixta has retired. Having worked in Austria for 25 years, Sixta arrived to Aalto in 2007, where his research in biorefineries helped create, among other things, the Ioncell process, a technology that turns used textiles, pulp, and paper into new textile fibres sustainably and without chemicals.
