Clean Harbors (CLH) said Thursday that its latest study on per- and polyfluoroalkyl substances affirmed that the company's commercial incineration facilities can destroy multiple forms of PFAS, also known as, forever chemicals, that pose significant risk to human health.

The study was conducted in November at a Clean Harbors incineration facility, with onsite participation from the US Environmental Protection Agency and Department of Defense, the company said.

Clean Harbors said the study has also shown that the PFAS chemicals were destroyed while surpassing US Environmental Protection Agency's OTM-50 and 0010 emission standards.

The company said the latest study demonstrated that emissions resulted from the PFAS destruction were "two to eight orders of magnitude safer" than any state of federal ambient air limit or guideline.

The test results were shared for review and validation of the study's results with two third-parties -- Melvin Keener, executive director for the Coalition for Responsible Waste Incineration, and Dr. Jens Blotevogel, a principal research scientist at Commonwealth Scientific and Industrial Research Organization, the company said.
