Vosteen Consulting GmbH was founded in 2001 by Prof. Dr.-Ing. Bernhard W. Vosteen to use own experiences from 45 years of industrial research and development.
Dr. Vosteen is a process engineer (diploma thesis on "Theoretical Thermodynamiics" in 1964 at the TU Berlin). In 1965 he became a Ph.D. student at the Institute of Heat and Fuel Technology at the Technical University of Braunschweig (doctoral thesis on "Coupled Heat- und Mass-Transfer" in 1970, Doctor-Father: Prof. Sergei Traustel).
In 1971 Dr. Vosteen became a member of the R & D department of Babcock-Schilde-Haas GmbH, Bad Hersfeld; he worked there as a specialist for the calcination of gypsum in cookers, rotary kilns and autoclaves, spending several years on the drying of gypsum products; still today his work on "staged drying" of gypsum wallboards is well known. In 1975, Prof. Vosteen changed over to BAYER AG became the head of a group "drying technology" of the central engineering research at BAYER AG, Leverkusen; he and his staff (25 employee) were tackling the design, commissioning and optimization of almost all drying processes, such as those are used at the BAYER sites in Leverkusen, Dormagen, Ürdingen and Brunsbüttel. A special focus at that time was "contact drying" as applied in different chemical industry divisions. In 1985, Prof. Vosteen moved to L & C Steinmüller GmbH, Gummersbach, where he was head of the R & D department with a staff of 50 employees, working at a wide range of developments in the fields of coal and waste incineration. In 1990, Prof. Vosteen returned to BAYER AG, working at first externally on the incineration and co-combustion of plastic waste and further on pyrolysis of car shredder waste (applying the Schwel-Brenn-process of Siemens). From 1992, Dr. Vosteen was working internally with BAYER / CURRENTA at process development in waste incineration at all running kilns and in wastewater and sewage treatment.
From 1995 until 2008, Prof. Vosteen was teaching alternately about "thermal waste treatment" and "sewage sludge treatment" at the TU Clausthal (Institute for Energy Process Engineering and Fuel Technology, Prof. Rudolf Jeschar and later Prof. Roman Weber) and at the Martin-Luther-University Halle-Wittenberg (Institute For environmental protection technology, Prof. Heinz Köser, at the Merseburg campus).
A special focus of Prof. Vosteen's research within BAYER/CURRENTA as well as at the named universities was waste incineration, co-combustion of wastes in coal-fired boilers, and finally the abatement of mercury emissions. Many of his former students, graduates and doctoral students are now recognized project leaders and experts in combustion technology and flue gas cleaning.
The company is run today by Prof. Vosteen and his sons Konrad and Johann Vosteen.
