Sustainable Solutions for a Toxic Free World

Trusted experts in PFAS free solutions

PFAS comes in different sizes, with Ultra-Short Chain PFAS, Short Chain PFAS and Long Chain PFAS.

The chain length also affects how PFAS interact with the body.

Ultra-Short Chain

Definition Classed as C3 and below

Water Soluble?

Highly water soluble compounds that can break down into TFA in the environment.

Toxicity

Generally less toxic than longer-chain PFAS.

Common Examples

i) Refrigerants - R- 134a and R 410A;

ii) Precision cleaning - trans-1-chloro-3,3, 3-trifluoropropene.

Different Types of PFAS

Short Chain

Definition Classed as C4 to C6

Water Soluble?

More mobile and soluble in water than long chain, leading to wider environmental spread. They are also more difficult to remove from contaminated water using traditional methods like activated carbon filtration.

Toxicity

Less bioaccumulative than long chain, but still pose health risks.

Common Examples

i) Hydrophobic coatings across multiple industries PFBA;

ii) Fire fighting foams and concentrates - 6:2 FTAB;

iii) Metal plating industry 6:2 FTS; and

iv) Paper and packaging - PFBS.

Long Chain

Definition Classed as C7 to C12

Water Soluble?

Less soluble in water and more likely to accumulate in specific areas. They tend to bind strongly to organic matter in soil and sediment.

Toxicity

Highly toxic. Exert toxicity by binding to proteins, altering their structure and function.

Common Examples

i) Hydrophobic coatings across multiple industries;

ii) Legacy Fire fighting foams & concentrates;

iii) Metal plating; and

iv) Include PFOA (perfluorooctanoic acid) and PFOS.

PFAS Regulatory

PFOS and PFOA (which would include AFFF firefighting foams) are already banned in most countries, with wider PFAS restrictions to follow.

Industries such as chemical manufacturing, metal plating, petroleum refining, and the military face significant challenges due to these evolving regulations.

These sectors that are already grappling with costly PFAS-related litigation, now face a slew of stricter directives to manage ongoing waste discharge and groundwater contamination, critical for maintaining regulatory compliance and public trust.

This regulatory pressure has amplified the demand for effective PFAS treatment solutions. Furthermore, new regulations in the UK, USA, France and EU have also imposed stricter limits on PFAS in drinking water.

After capture, the current method of disposal of PFAS waste currently requires costly, specialist, high temperature incineration.

As new legislation has come in limiting the use of PFAS, the limited incineration capacity has caused costs and lead times to triple. There are also questions about the efficacy of incineration and its further cost to the environment.

Our Methodology

Step 1

Profiling the Stream to be Treated

No two waste streams are the same - our solution will develop a bespoke processing methodology around the composition of the waste, your specific requirements and anticipated flow rates, whilst taking into account seasonal variance if required.

Step 2

Ion Exchange Resin - Removing the PFAS

Ion Exchange resin works similarly to the Granular Activated Carbon (“GAC”) employed in legacy water treatment systems. The resin acts as a ‘sieve’ capturing the desired component of the waste stream.

Step 3

'Regenerating' the Ion Exchange Resin

We use a proprietary, drinking water compliant regeneration process to displace the PFAS from the resin. This means the same resin can be used many times, saving costs, and avoiding the need to destroy it after every single use.

Step 4

Destroying the PFAS

We employ Advanced Electrochemical Oxidation Processes (“AEOP”) to degrade the PFAS.

Leveraging our partnerships with leading universities and research institutions, we work on key areas of technology evolution, including sustainability, materials, chemistries and manufacturing processes.

We have contacts at the highest levels of government and are actively involved in setting the agenda for regulation in this area, as recognised industry experts.

The 2Encapsulate USP

Seamless, Sustainable, Scalable.

Our AEOP solution offers significantly lower costs-per-mass-processed than our competitors; it also offers clear and quantifiable advantages in terms of its efficiency, ESG alignment and scalability.

Our capture technology is capable of seamlessly integrating with other water treatment solutions, providing a fully flexible solution.

We Designed Drinking Water Approved Technology

Applicable to both water and environmental cleanup, as well as non-drinking water cleanup and industrial processing.

Our team brings in-depth knowledge and practical experience in tackling PFAS-related issues across a wide array of sectors, including government, aviation, property management, automotive and textiles, manufacturing, waste management, utilities, power generation, oil and gas, and mining. We also work on sites impacted by fire incidents.

Trackable, traceable and with regulatory accountability, our environmentally-friendly remedial solutions are also significantly more cost-efficient than those of our competitors.

What We Bring

Our clients vary from large-scale manufacturers to small businesses and we're dedicated to helping a wide range of industries thrive.
