In Duluth, Minnesota, an innovative project aims to repurpose the heat from millions of gallons of treated wastewater discharged daily into the St. Louis River. Spearheaded by a local nonprofit, the initiative seeks to convert the approximately 90-degree effluent into a renewable energy source for local heating.
With a $700,000 federal grant, the project plans to use a network of underground pipes and pumps to distribute the wastewater's heat to hundreds of homes in the area. This method has precedents in countries like Finland, Denmark, and China but represents a novel approach in the U.S.
