Algae-to-energy cleans wastewater too

A plan to use algae to simultaneously treat wastewater and produce the raw materials for biofuels won the inaugural Clean Energy Prize on Friday.

The students at Univ. of Michigan who won the top prize of $65,000 plan to use it to start up the business.

“We’re trying to address two major global concerns: clean water and clean energy,” said Geoff Horst, an ecology doctoral student at MSU who developed the technology,” and we can do that with one process.”
