This year's Dow Energy Prize was awarded to Mark van Loosdrecht for his contribution to an innovative biological waste water treatment method.

This invention cuts the energy used in waste water treatment by 30% and may well bring about a major change in the way we treat waste water in a few years.
Two dissertations were also awarded the Dow Dissertation Prize. One prize went to Waldo Beek for his pioneering research into alternatives to the traditional solar cell; the other was awarded to Pepijn Pronk for his study of ice slurry using a fluidized bed heat exchanger.
