Gross-Wen Technologies has secured a $1 million loan from the Iowa Economic Development Authority via the State Small Business Credit Initiative Innovation Fund. The funds will support hiring and market expansion for the company, which specializes in algae-based wastewater treatment technology.

This system, utilized in cities like Slater, Iowa, employs vertical conveyor belts coated with algae to absorb nitrogen and phosphorus from wastewater. Gross-Wen's largest installation in Pasco, Washington, is the world's largest algae-based treatment site, expected to reuse 1.5 billion gallons of wastewater annually. The loan aligns with Gross-Wen's growth strategy as demand for sustainable water treatment solutions rises.
