About Gross-Wen Technologies

Gross-Wen Technologies has developed a wastewater treatment system that utilizes algae to remove nutrients like nitrogen and phosphorus from the water. The core of their offering is the patented Revolving Algal Biofilm (RAB™) system, which is a reliable and effective solution for both municipal and industrial clients.

The company's business model is centered on not just treating wastewater but also creating a value-added product from the process. The nutrient-rich algae that are cultivated during the treatment are harvested and can be converted into slow-release fertilizers, bioplastics, or biofuels, including Sustainable Aviation Fuel (SAF). This approach changes the economics of wastewater treatment by creating a new revenue stream from a byproduct that is typically considered waste.

By turning pollutants into a resource, Gross-Wen Technologies offers a sustainable and environmentally friendly alternative to traditional wastewater treatment methods. The company serves a diverse client base, from municipalities looking for cost-effective nutrient removal to industrial facilities needing to meet stringent environmental regulations.
