TRS Group Patented PFAS Treatment

The U.S. Patent and Trademark Office has awarded TRS Group (TRS) a patent for the thermal treatment of per- and polyfluoroalkyl substances (PFAS). Sometimes called “forever compounds,” this class of about 5,000 contaminants does not naturally degrade and can remain in our environment for centuries. The patented process uses heaters to raise soil temperatures to desorb and volatilize PFAS. Importantly, the target temperatures are high enough to degrade soil organic matter but still low enough to mitigate the risk of forming potentially dangerous PFAS by-products.

“TRS is excited to apply our heating technologies to remediate these harmful contaminants,” said Brett Trowbridge, CEO of TRS. “Our technology is a game-changer, as we can target the source of these forever chemicals, lowering the cost and improving the sustainability of remediating a complex problem.”

TRS is an employee-owned (ESOP) environmental remediation firm with joint ventures in Europe, Brazil and China. Using our thermal remediation technologies, we have cleaned more than 160 sites. Our research and development team is focused on lowering the costs and improving the sustainability of thermal remediation technologies.
