New method transforms “forever chemicals” into harmless substances, minimizing hazardous waste.
RESTON, Va.—April 22, 2025—Noblis, a leading provider of science, technology and strategy services to the federal government, today announced it has been awarded U.S. patent number 12,246,974 for a groundbreaking system and method for the efficient and safe removal of per- and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” This method offers a substantial improvement over existing PFAS removal processes, which often produce more hazardous substances.
The patented technology is applicable to a wide range of contaminated sites, including groundwater, industrial wastewater and other affected environments. The method involves a multi-stage process using concentrated contaminated waste, which is then heated with calcium oxide in a special reactor. This reactor turns the harmful chemicals into harmless ones. Leftover products are released as water vapor and air, ensuring a very clean result.
“This patent represents a significant milestone in our commitment to developing innovative and effective solutions for environmental challenges,” said Mile Corrigan, president and CEO of Noblis. “Our novel PFAS removal technology offers a safer and more efficient way to protect communities from the harmful effects of forever chemicals.”
“Seeing this invention come to fruition is incredibly rewarding,” said Dr. Javier Santillan, a Noblis environmental engineer and the lead inventor of the technology. “We focused on creating a process that not only eliminates PFAS but also minimizes the production of hazardous byproducts. I’m excited to see the positive impact this technology will have on environmental cleanup efforts.”
