Breakthrough in Bioremediation of PFAS
A novel technology that can efficiently bind to and break down per- and polyfluoroalkyl substances (PFAS) in the environment was developed by scientists at Texas A&M Agrilife Research. The new approach uses a plant-based material that adsorbs PFAS, and microbial fungi that literally eat up the so-called “forever chemicals.” Michigan has some of the most extensive PFAS contamination in the country, rendering fish caught in rivers unsafe to eat. PFAS have been linked to adverse health effects in humans and wildlife.
A fungus called “white rot” has shown promise to degrade PFAS. The researchers in this study used an abundant and renewable component of dry plant matter to create a porous framework as a low-cost, efficient, and sustainable alternative for PFAS remediation made from the leaves, stalks, and cobs of corn plants left in the field after harvest.
In the new study, the researchers found that their platform successfully bound PFAS at higher concentrations than other currently available sorbents. After two weeks, more than 98% and 99% of PFOA and PFOS, respectively, were removed with the PFAS degraded biologically into less toxic products.
