As industries try to move away from using products with 'forever chemicals,' here's one possible replacement

PFAS, also known as forever chemicals, have been linked to human illnesses and diseases but are still being used in commercial products because there isn't a functional substitute.

One of those products is firefighting foam, but Wisconsin farmers think they may have a solution, which was recently tested in Dalton, Georgia, reports Courtney Everett of Wisconsin Public Radio. "Farmers and volunteer firefighters were using a new soybean-based product called SoyFoam, which holds the potential to significantly reduce the health risks associated with PFAS exposure."

Wisconsin Soybean Marketing Board President Pat Mullolly, who was present at the demo, told Everett, "It looked like the consistency of paint. It was a brown-type substance, maybe a little bit thicker than salt. They inject that into the water stream, and it creates foam." Everett added, "According to Mullolly, the biodegradable foam could eliminate the use of PFAS in firefighting foam. The chemicals have been linked by the U.S. Fire Administration to health risks and groundwater pollution."

Although SoyFoam technology is in the testing phase, "Mullolly is hopeful the product and other ongoing state projects can grow Wisconsin's agricultural economy," Everett reports. "Economic opportunities for soybean farmers across the United States are growing, Mullolly added." He told Everett, "There's some soy oil in Goodyear tires and Sketchers shoes. Dalton, Georgia, is the world headquarters for Astroturf, and they're using soy oil in their polyurethane."
