A thermo-radical technology that brings the flame to where traditional treatments cannot reach

PFAS degradation in concentrated liquid matrices

The real problem with PFAS is not capturing them, but destroying them

Public discourse on PFAS is simple: they are “persistent” compounds, widespread across all environmental matrices and difficult to treat.

The industrial reality is far worse. Ninety percent of the technologies used in treatment plants move PFAS (adsorption, resins, membranes), but do not destroy them. This creates a concentrated residue that must be managed elsewhere, often with high costs and increasing risks.

Meanwhile, Europe is preparing for a much more restrictive regulatory framework, with a proposed PFAS ban and increasingly stringent guidelines.

The point is clear: there is a need for technologies that can not only remove PFAS, but mineralize them.

This is precisely the industrial challenge addressed by K-INN Tech’s technology.

K-INN Tech’s solution: using the flame as a chemical reagent

The pilot plant developed by K-INN Tech is neither an incinerator nor a conventional thermal oxidizer.

It is a thermo-radical oxidizer that uses a flame specifically engineered to generate a radical-rich environment capable of directly attacking C–F bonds, the strongest bonds in organic chemistry.

In other words: it does not merely heat, it reacts.

And this is the difference between “breaking PFAS” and “breaking PFAS completely.”

Why is it different from an incinerator?

In conventional incinerators, the liquid is sprayed by atomizing lances around or onto the flame.

Here, instead, thanks to a patented system, the matrix is forced to pass longitudinally through the entire length of the flame, exactly where the presence of radicals, and therefore radical reactivity, is at its highest.

If you want to destroy PFAS, you have to bring them precisely there.

What does this change for a plant designer or an operator?

From removal to destruction

There is no longer a residue to be disposed of elsewhere. Fluorine is fully converted into HF, then removed as fluoride salts, measured and safely neutralized.

Concentrates are no longer a problem

The treatment works on:

  • untreated leachates
  • concentrated leachates
  • super-concentrates with dry matter up to 24%
  • concentrated foams from SAFF®
No undesired by-products

Degradation is verified through a fluorine mass balance, not through partial analyses of selected target PFAS. This means:

  • no fragmented PFAS
  • no fluorinated intermediates
  • no "analytical disappearance" of PFAS, which in reality conceals the fact that the problem has not been solved

How the plant works

From an operational standpoint, the system has a simple configuration:

  • 20 kW methane burner (~2m3/h)
  • converging flame
  • liquid feed at the center of the flame
  • 1 L/h of liquid matrix fed, even with very high viscosities
  • confined combustion chamber
  • flue gases treated with quench + activated carbon
  • sampling on alkaline traps for measurements of the produced HF

It is a pilot system, yes, but designed with an industrial approach: replicable, scalable, and controllable.

This technology is relevant, now

There are three reasons: not marketing-driven, but market-driven, why this technology is relevant.

1. Incoming regulations

PFAS restrictions at both European and national level will make it increasingly unacceptable to:

  • produce contaminated concentrates that must be disposed of
  • transport hazardous residues
  • rely solely on activated carbon or resins

Those who can demonstrate the definitive destruction of PFAS will be ahead.

2. Growth of concentrates from other treatments

Every plant that installs activated carbon filters, resins, membranes, or uses SAFF® technology generates a concentrated residue.

Today, that residue “has no home”, but tomorrow, we may be able to provide one.

3. Cost pressure and environmental responsibility

Utilities and industrial operators must:

  • reduce environmental risk
  • control disposal costs
  • espond to increasingly stringent demands for transparency regarding PFAS degradation

A technology that mineralizes PFAS therefore represents a clear competitive advantage.

Conclusions

K-INN Tech’s pilot plant demonstrates that it is possible to mineralize PFAS even in the most challenging matrices:

  • concentrated leachates
  • post-treatment residues
  • liquids with high viscosity and dry matter

We are not talking about removal or partial degradation.

We are talking about breaking C–F bonds, all the way to conversion into HF, verified through a fluorine mass balance closure (average 95%).

It is a thermo-radical technology, robust, scalable, and ready for industrial applications, that introduces a simple yet disruptive principle:

If you truly want to eliminate PFAS, you must bring them to the heart of the flame, where the radicals are.
