Position: Chair Geochemistry (emeritus from march 1997)

Curriculum Vitae

Date of birth: 26-02-1932
Place of birth: Arnhem

Education:

1957	Obtained doctoral degree in 1957; majored in Petrology, with secondary subjects Geophysics and Structural Geology. Worked in 1954 3 months in a German lead-zinc mine, and took part in a geophysical expedition on board of a submarine of the Royal Dutch Navy
1961	PhD with mention "cum laude"

Career:

1957-1961	Exploration geologist with Maden Tetkik Arama Enstitüsü (Geological Survey of Turkey), with a 3 month interruption in 1961 as research fellow of the German Research Organisation.
1961-1972	Scientist at Utrecht University, in charge of setting up and running a high pressure/high temperature laboratory
1965-1966	NATO Research Fellow at Princeton University, USA
1972-1997	(retired in 1997)Full professor of geochemistry and experimental petrology at Utrecht University.
1973-1996	Part-time lecturer environmental geochemistry at IHE/Delft.
1979-1980	Senior officer of UNESCO, to give a course to geologists of the Geological Survey of Greece.
1996-March 2003	Part-time professor of geochemical engineering at IHE/Delft

Professional interests:

Although the early scientific career was mainly directed towards (experimental) petrology, environmental geochemistry became increasingly more important from 1970 onwards. This has led to the development of a number of environmental technologies, based on optimization of natural geochemical processes. Some of the larger projects include:

• Development of a process for the neutralization of waste acids by olivine; a large project is supported by the EC.
• Development of a process to break down jarosite by reaction with organic waste streams under moderately elevated temperatures and pressures in autoclaves, e.g. of the VERTECH type. Project supported by EC.
• Zeolitisation of coal fly ashes. Large project in collaboration with KEMA.
• Formation of self-sealing and self-healing isolations under toxic waste deposits, by the reaction between two contrasting waste types.
• Recovery of manganese from manganese tailings in the Nikopol area, Dnepropetrovsk Oblast, Ukraine.

The application of natural processes to solve environmental problems has been defined as "Geochemical Engineering"; the subject was formalized in a paper by Schuiling in 1990 in Applied Geochemistry ("Geochemical Engineering; some thoughts on a new research field").
Approximately 50 PhD-students have obtained their degree under his supervision.
Of special interest to the present project are the years spent in mining exploration as well as visits to mining districts all over the world (India, Philippines, Brazil, Canada, Russia, Ukraine, several countries of the EC). Noteworthy is a NATO-sponsored inspection tour of mining wastes in Southern Poland.
