About Gross-Wen Technologies

Gross-Wen Technologies exists to help municipalities and industrial clients sustainably treat water in more effective and affordable ways! Our technology was developed at Iowa State University, and from there, we’ve grown into a trusted source for environmentally friendly wastewater processing.

Sustainable and Effective Water Treatment

Since our company’s conception, our mission has been simple: to provide algae-based water treatment that is sustainable, effective, reliable and affordable. We’ve reinvented the way nutrient pollutants are viewed through our process of extracting nutrients from wastewater with algae then recycling those nutrients through a fertilizer or bioplastic product.
