Gross-Wen Technologies is a wastewater treatment technology company using algae instead of bacteria or chemicals to recover nitrogen and phosphorus from wastewater. The by-products are harvested as crops and used for other purposes such as fertilizer, shoe insoles, and sustainable biofuels. With multiple patents, Gross-Wen Technologies’ algae-based solution, the Revolving Algal Biofilm™️ system (RAB), is considered the most sustainable way to treat wastewater. During the treatment process, algae is consuming CO2 from the atmosphere, then the CO2 containing algae is used as a slow-release fertilizer. In 2014, the company was founded by Dr. Martin Gross and Dr. Zhiyou Wen and is based on a technology developed at Iowa State University. Learn more about Gross-Wen Technologies at www.algae.com.
