TECHNOLOGY

Physical not Chemical

Proprietary product locks PFAS into a variety of concrete materials through a physical PFAS immobilisation mechanism. Physical mechanism is advantageous, as changes in environmental chemistry have a lesser impact on immobilised PFAS fraction.

Optimisation Range

Allows simultaneous sustainable use of vaste amounts/variable PFAS impacted materials, with associated cost reduction and risk minimisation achieving non-detect leaching of any PFAS.

Useful Structures

Can be incorporated into concrete mix designs to achieve equal or greater material strength (> 32MPa) when compared to untreated concrete. Ambiolock is valuable for high traffic area use.

Risk Resilience

Beyond extending the lifetime of created concrete or stabilised sand, Ambiolock has demonstrated insignificant leachability when treated concrete is broken back into powder form.

AMBIOLOCK is incorporated into a concrete substatemix to achieve equal or greater material strength when compared to untreated concrete, while reducing leachable fractions of PFAS by up to 99%.

*Mass flux of all PFAS components to ND

AMBIOLOCK tests demonstrated NO appreciable leachable PFAS fraction when concrete or stabilized soil crushed.

AMBIOLOCK Stabilised Sand

AMBIOLOCK Stabilised Concrete

Crushing of Ambiolock treated concrete into various particle sizes and analysis of the separated particle size fractions for PFAS leaching evaluation. Represents longterm use, wearing down of concrete or stabilised soil and possible disposal in the future.

AMBIOLOCK Use Evaluation

The AMBIOLOCK Technology use is optimised through a process of:

* Consultations with Client to consider the range of end use opportunities for the specific PFAS impacted materials;
* Access to impacted materials and completion of Bench Top Study to evaluate and ensure precise mixing specifications to achieve desire end use; and
* Project Scale-up definition – with AMBIOLOCK, aggregate. PFAS impacted material components. Includes RAP, with costings considerations/ comparatives for Client decision.

Prefabricated AMBIOLOCK Concrete Slabs

AMBIOLOCK with Other PFAS Impacted Materials

Waste concrete can be crushed to a proper size and used as aggregate. AMBIOLOCK’s value is the inclusive flexibility for other impacted materials whether they be liquid of solid to be included into the concrete substrate. Note: bench top study requireto ensure concrete substrate is fit for purpose.

Some of the following PFAS Impacted materials that can be considered are:

Liquids

Waste Water

Solids

Concrete

Bitumen

Mixed Solid Waste

Soil

Tank Sludge

Heavy Metals

Each Site and Project is Different

– logistics, impact levels, materials worked with, regulatory obligations, desired – highest value use…

However:

ReUse/ReCycling impacted materials offer obvious cost savings in both materiasl and limiting disposal offsite costs;
Valued Public Perception – Effective Risk Mitigation;
Green Solution/Construction – Climate Change Positive
