UConn professor seeks to turn grease into fuel

STORRS, Conn. (AP) — A year ago, Richard Parnas had never heard of brown grease: sticky, stinky, remnants of sludge sucked from grease traps at restaurants, bars and commercial kitchens. The glop for years has been considered useless, a common clog-inducer at sewage treatment plants, often burned as costly waste.

Parnas immediately saw the potential, one that he hopes could change the fuel industry and improve the environment. If he is correct, the University of Connecticut professor’s vision also could make him and his partners wealthy.
