EPA Study Finds Reworld Facility Destroys 99% of PFAS Surrogate

An Environmental Protection Agency study has found that a Reworld waste treatment facility in Florida destroyed up to 99 percent of a conservative surrogate compound used to represent PFAS chemicals, with measured concentrations of the chemicals either non-detectable or well below air quality standards. The study, conducted at the company's Lake County Thermomechanical Treatment Facility in Okahumpka, was released this week to validate Reworld's recently launched ReAssure PFAS Destruction service, which the company says offers the largest full-scale PFAS destruction capacity in the country. The underlying EPA testing was carried out in spring 2024, more than two years before these results were made public.

 

Why PFAS Are Difficult to Eliminate

 

PFAS, often called forever chemicals, are a class of synthetic compounds used across thousands of everyday products, including carpets, textiles, paper products and packaging, prized for their resistance to heat, water and grease. That same chemical stability is what makes them so difficult to break down once they enter the environment, since they persist and accumulate rather than degrading over time, and as products containing them reach the end of their life and enter municipal solid waste streams, the chemicals can continue circulating unless something actively destroys them.

Because the exact PFAS content of incoming waste cannot be precisely measured, the EPA study used a stable fluorinated surrogate gas injected directly into the furnace rather than testing real waste with unknown PFAS levels. That approach was designed to represent a worst-case scenario, since the surrogate is described as harder to destroy than most PFAS compounds actually found in waste, meaning a high destruction rate against it suggests the process should perform at least as well against the PFAS typically present in municipal and industrial waste streams.

How Thermal Destruction Works at This Scale

 

Reworld's facilities process waste at temperatures above 1,100 degrees Celsius, a threshold widely cited in the industry as necessary for breaking the carbon-fluorine bonds that make PFAS so persistent. The company frames its approach around three established variables for thermal destruction, time, turbulence and temperature, and adds documented chain-of-custody tracking from waste pickup through to final destruction, which it markets as traceability distinct from the underlying combustion science itself.

The study also found no products of incomplete combustion during normal operating conditions, an important qualifier because incomplete destruction of PFAS can, in some circumstances, generate smaller fluorinated byproducts that carry their own environmental concerns. The absence of such byproducts under the tested conditions is what supports the claim that the process achieves genuine destruction rather than simply transforming the chemicals into a different persistent form.

The Scale Claim Behind ReAssure

 

Reworld says its ReAssure service provides access to around 17 million tons of processing capacity through its treatment facilities across the United States, supplemented by more than 50 material processing facilities that prepare non-bulk PFAS waste for delivery. The company describes that capacity as more than 17 times greater than hazardous waste incineration options, though this figure comes from Reworld itself rather than an independent industry assessment. The service also includes wastewater treatment using activated carbon and coordinated logistics, intended to let the company handle PFAS across a wider range of contaminated materials than destruction capacity alone would allow.

Chief executive Azeez Mohammed framed PFAS contamination as one of the defining environmental challenges of the current generation, arguing the EPA study demonstrates that compounds engineered to resist degradation can be permanently destroyed at scale. Whether that capacity claim holds up as demand for PFAS destruction grows, and whether other waste treatment operators can validate comparable destruction rates independently, will determine how much of the PFAS waste stream Reworld's approach can realistically address relative to the scale of the problem it describes.
