The RemBind® technology was originally developed in 2010 in collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
While the product was initially designed to bind up gasworks contaminants, independent testing by AirServices Australia in 2015, showed the potential of RemBind® to immobilise PFAS. After further product refinement, it was demonstrated that RemBind® had the unique capability to bind short and long-chain PFASs, setting RemBind® apart from other reagents.
Thousands of tonnes of PFAS impacted soil have been treated at full-scale in North America, Europe, Australia and New Zealand with regulatory sign off through our global network of distributors.
RemBind® contains a patented blend of activated carbons and clay minerals designed to bind PFAS compounds.
These so called “mixed mode” sorbents forms hydrophobic interactions with the C‑F backbone of the PFAS molecules, with carefully selected activated carbons doing the heavy lifting.
The clay mineral components bind to the charged head of the PFAS compounds through electrostatic interactions, providing a second mode of binding which gives RemBind® an advantage in binding shorter chain PFAS molecules which are becoming increasingly relevant to regulators given their higher mobility in the environment.
The clay mineral component also gives RemBind® a number of material handling benefits in that it settles quicker than many other fine powders in the field, and it forms a ‘milky’ slurry ideal for dust-free applications.
