Otto Wienhaus

Otto Wienhaus (2012)

Otto Wienhaus (born August 14, 1937 in Tharandt ) is a German forest engineer and chemist. He conducted application-oriented research on the production of activated carbon from wood residues and later on the production of binders for wood-based materials from lignin , tannins and wood tars . After 1990 he devoted himself to the chemical fundamentals of forest damage research . From 1990 to 2002 he held the professorship for plant chemistry and ecotoxicology at the Faculty of Forest, Geo and Hydro Sciences at the Technical University of Dresden in Tharandt .

Life

Otto Wienhaus is the fourth child of Adelheid geb. von Oertzen and Heinrich Wienhaus , one of the most important terpene chemists of his time. In 1955 he passed the Abitur at the extended secondary school in Freital. From 1955 to 1956 he completed an apprenticeship in forestry at the state forestry company in Lübben (Spreewald) .

From 1956 to 1961 he studied forestry at the Technical University of Dresden with a degree in forest engineering. The subject of the diploma thesis was: "Some investigations on storm-affected spruce trees in a test area in the Oberböhmsdorf district of the Schleiz State Forestry Company ". He was the best graduate of the 1956 enrollment class. In 1961, he worked as an assistant at the Pirna State Forestry Company in Königstein in the Elbe Sandstone Mountains.

From 1961 to 1966 he studied chemistry at the Technical University of Dresden. The subject of the diploma thesis was “Some experiments on dimethyl sulfoxide wood digestion as a basis for further investigations”. As a scientific assistant from 1966 to 1986 at the Tharandt Institute for Plant and Wood Chemistry , he devoted himself to the hydrogenolysis of lignin with the aim of increasing the yield of mono- and oligophenols. In a high-pressure test facility initiated by him, he carried out series of tests on a semi-industrial scale, which led to a higher phenol yield by pasting the lignin with medium oil from lignite . On the basis of a dissertation on this under the title: "Basics of the fragmentation of pulp waste liquor lignins under the conditions of high pressure hydrogenation", he was awarded a Dr. rer. nat. PhD .

He then did research on the production of activated carbon from wood residues such as wood chips, bark and xylitol. A dissertation on the subject of "Thermal-chemical refinement of wood residues into wood and activated carbons" led to a PhD B for Dr. sc. nat.

In 1981 Wienhaus was awarded the Facultas Docendi for the field of wood chemistry, and in 1986 he was appointed full professor for wood technology at the Faculty of Mechanical Engineering of the Technical University of Dresden. He researched the use of lignin, tannins and wood tars for the raw material-saving production of binders for wood-based materials. In 1990 he was appointed to the professorship for plant chemistry and ecotoxicology and from 1991 onwards he devoted himself to the chemical fundamentals of immissions damage research.

From 1990 to 1994 and from 1996 to 2000 he was director of the Institute for Plant and Wood Chemistry in Tharandt . From 1991 he worked on the reconstruction of the immission ecological test field in the Tharandt forest not far from the Warnsdorf spring. With the help of a computer-controlled pollutant gas metering system, plants can be artificially exposed to the pollutant gas emissions that occur in nature.

From 1998 to 2000, Wienhaus coordinated the user interests of various university institutions so that they could move into the newly built “Judeich-Bau” at Pienner Strasse 19. Its construction costs amounted to 25.23 million DM, the costs of the initial installation to 2.67 million DM.
