Gross-Wen Technologies is an Iowa-based company working to solve one of the world’s largest problems, water quality. The company was founded in 2013 by Dr. Martin Gross and Dr. Zhiyou Wen, and is based on a technology they developed at Iowa State University. The algae system is capable of cost effectively recovering nitrogen and phosphorus from wastewater. Martin and Zhiyou brought on Dr. Darren Jarboe as a co-founder in fall 2014.
