AMES, Iowa (November 2, 2017) — Iowa State University Startup Factory today announced Gross-Wen Technologies, Inc. (GWT) has been selected to participate in the Association of Public and Land-grant Universities (APLU) and the Association of American Universities’ (AAU) inaugural “University Innovation and Entrepreneurship (I&E) Showcase.”

According to the APLU website, the showcase aims to “promote the importance of federally-funded university research and demonstrate how university-led entrepreneurial engagement contributes to the innovation economy.”

GWT, founded in 2013, is commercializing an algal wastewater treatment technology developed at Iowa State.  The technology, called the Revolving Algal Biofilm Treatment System (RAB), removes nitrogen, phosphorus and other pollutants from municipal and industrial wastewaters. The algae biomass that is produced can then be used as a slow-release algal fertilizer.

GWT founder and President Dr. Martin Gross said GWT was chosen as one out of 22 university-affiliated startups to be featured at the showcase out of a field of 100 highly competitive applications received from over 40 institutions across the country.

“I was thrilled to receive the confirmation from APLU and AAU that we had been selected to participate,” Gross said. “This is a unique opportunity for us to showcase our innovation and to demonstrate how federal and state entrepreneurial programs can be critical in leading to the commercialization of new technologies like ours.”

GWT will join the select startups in an afternoon poster session and reception at the APLU Annual Meeting on November 13. On November 14, the startups will be featured in a Capitol Hill Exhibition and Reception.

GWT is a member of the ISU Startup Factory’s inaugural cohort that graduated in June. GWT is located in the ISU Startup Factory, housed at the Iowa State University Research Park.
