Johannes "Hans" van Leeuwen (born 1946 in Gouda) is a Dutch-American emeritus professor of Civil, Construction and Environmental Engineering at Iowa State University and an entrepreneur in ethanol co-product development through Vandanco Technologies, LLC.

Biography[edit]

Van Leeuwen lived in the Netherlands, South Africa, Australia and has resided in the United States since 2000. He is an emeritus professor in the Department of Civil, Construction and Environmental Engineering at Iowa State University in Ames, Iowa. Together with Balaji Narasimhan, he was given a Vlasta Klima Balloun Professorship at Iowa State University.[1]. Previously he had been a professor at the University of New England, Australia, Griffith University, Australia, and the University of Pretoria.

Education[edit]

  • University of Pretoria (South Africa), 1988 - D Eng, environmental engineering
  • University of Pretoria, 1983 Graduate Diploma of Tertiary Education
  • University of Pretoria, 1979 - MS, engineering, water utilization
  • University of Pretoria, 1975 BS, chemical engineering.

Research[edit]

His research includes the recovery of byproducts from liquid wastes and sludges, fungal treatment of food processing wastewater, and reuse applications of residues from water softening. He has several patents to his name. He has developed processes for creating new products at ethanol plants, purifying alcohol, and keeping exotic species out of coastal waters through disinfestation of ballast water with bromine production through ozonation to avoid spreading feral species.

He has focused his attention on making added-value products from crops, including animal feed, food, ethanol and purer potable alcohol. He developed a new animal feed, potentially a new human food source, by developing a process for cultivating fungi and deriving valuable biochemicals on corn processing leftovers being commercialized in Europe.

His physical-chemical alcohol purification process has found application in the production of impurity-free IngeniOz vodka in Iowa [2].
