Education

  • D. Eng. Environmental Engineering, University of Pretoria (South Africa), 1988
  • Graduate Diploma of Tertiary Education, University of Pretoria, 1983
  • M.S. Engineering, Water Utilization, University of Pretoria, 1979
  • B.S. Chemical Engineering, University of Pretoria, 1975

Interest Areas

Dr. van Leeuwen's 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.
  • One of his developments, now owned by the Korean NK-03, is keeping exotic species out of coastal waters through disinfestation of ships' ballast water with bromine production through ozonation and now has been installed on five oil tankers.
  • The purification of alcohol makes the world's purest vodka possible and Oz Spirits LLC, of which he is the founder, is launching a product, IngeniOz vodka, based on this process involving ozone, activated carbon, and nanogold filtration.
  • He developed a new animal feed, potentially a new human food source, by developing a process for cultivating fungi on corn processing leftovers, with a product, MycoMeal, being commercialized.
