Using nature to solve problems.
Our short story.
In 2014, Gross-Wen Technologies was founded by Dr. Martin Gross and Dr. Zhiyou Wen at Iowa State University while developing GWT’s sustainable RAB™ system to help municipal and industrial clients effectively treat wastewater in more economical and reliable ways.
Since then, GWT has grown into a trusted source for environmentally-friendly wastewater treatment.

Our mission has always been simple.
Since its formation, the mission has been to provide a sustainable algae-based wastewater treatment that is effective, reliable, and economical.
We have reinvented the way pollutants are viewed through our innovative, patented process of recovering nutrients from wastewater with algae and then recycling those nutrient-rich algae into slow-releasing algal-based fertilizer – an additional revenue stream!
