- 1961, I joined the application department for paper chemicals of BASF in Ludwigshafen / Germany, as a fairly well experienced paper engineer. Because of my practical experience at the Massey Coater of Holmens, initially I worked as a paper coating specialist.
- 1963, I changed to the new established group of retention-drainage aids (RDA`s), flocculants and defoamers / deaerators.
- 1965, I became group leader of this team with worldwide responsibility, which lead me to frequent trips to all countries in the world with significant paper industries,
- especially to all West and East European countries, to North America, to Japan, Indonesia, South Korea and China.
- 1974, I became authorized officer and senior group leader for dyes and wet end chemicals, responsible for whole Europe.
- 1981, I got promoted to Director.
- 1984, I became the head of the Application sub-department for dyes and wet end chemicals with worldwide responsibility.
- 1990, as Vice President and leader of this sub-department, I was responsible for the worldwide business with paper dyes and wet end chemicals.
- 1997, BASF established a new Business Unit for all paper chemicals – wet end and coating – where I became the head of marketing.
- 2000, I got promoted to the leader of this Business Unit.
- 2002, after 40 years with BASF, I officially retired and worked for further two years in part-time as a project consultant for BASF.
In the last 45 years, I collected a lot of informations and experiences in papermaking, paper chemistry and technology, chemical additives, of the international paper and supplier market in general, of staff and business management, economics, marketing, product and business strategies, sales and service customs and last but not least how to reach customer satisfaction. Regular international contacts to the paper industry, to paper institutes and to Universities, as well as active memberships in paper associations, e.g. ZELLCHEMING, TAPPI, VPM, have been the basis and important network of my interesting and successful business life.
During my time with BASF, I presented almost 100 external lectures at national and international paper conferences, besides a lot of company internal speeches. As single author or co-author, I published several dozen articles in paper magazines and books. From my personal point of view, the most trend setting publications in chronological order are:
- 1. Produktionssteigerung und Kostensenkung durch Polyethyleniminderivate – LUSAP-Verfahren (Production Increase and Cost Saving by Polyethylenimine Derivatives – LUSAP-Process), Hubert Wilfinger, Werner Auhorn; Wochenblatt für Papierfabrikation 1968, No. 7, pages 201-207
- 2. Gewollte und ungewollte Wechselwirkungen von Retentionsmitteln mit anderen Inhalts- und Zusatzstoffen in Papierstoffsuspensionen (Intended and unintended interactions between retention aids and other substances in paper stock suspensions), Wolf Günder, Werner Auhorn; Wochenblatt für Papierfabrikation 1975, No..16, pages 581-592
- 3. Untersuchung von Störsubstanzen in geschlossenen Kreislaufsystemen (Investigations of Detrimental Substances in closed process water circuits), Werner Auhorn, Jaroslav Melzer; Wochenblatt für Papierfabrikation 1979, No. 13, pages 493-502
- 4. Polyvinylamin – Eine neue Klasse von Polymeren für die Papierherstellung mit umweltfreundlichen Eigenschaftsprofil (Polyvinylamine – a new Class of Polymers for Paper Manufacturing with Environment-friendly Properties), Friedrich Linhart, Werner Auhorn; DAS PAPIER, 1992, No. 10A. pages V38-V45
A further selection of my publications in magazines and books as well as some other informative printings about papermaking chemistry and technology from other authors and editors you will find in the separate site “Publications”.
- In recognition of my multifaceted contribution to the field of paper chemistry, the ZELLCHEMING awarded me with the ”Georg Jayme Commemorative Medal” in June of 1998, at their annual meeting in Baden-Baden, Germany.
- In 2002, I received from TAPPI Paper and Board Division the ”Technical Award and Harris O. Ware Prize” at their Technology Summit in Atlanta, USA. TAPPI especially emphasized my extensive knowledge of wet en chemistry, underlining the multitude of interactions in the wet end together with the synergies between papermaking and paper coating. In 1998 I was also an active team member of ”TAPPI Futurists project – The world in 2015”.
- The board of trustees of Deutsches Museum Munich honored me with the “Oskar-von-Miller-Badge in Bronze” in 2004, in recognition to my activities for remaking and modernization of the paper exhibition there and the implementation of a new multimedia show ”PapierLive”, where the visitors of the paper department of the museum get once a week in a visual conversation contact with several paper and board mills in Germany. By this, the first Museum TV worldwide has been established (www.papier-live.de).
