Projects & Activities

”AMBIOLOCK is a total solution, allowing for the re-use, recycling or disposal of a large variety of PFAS impacted materials. See the projects and activities for just a snippet of how AMBIOLOCK can be used.”

ACTIVITIES

Encapsulation fo PFAS Contamination in impacted concrete in fire fighting or fire training areas areas was conceptualised by AMBIOLOCK developers almost 10 years ago.

Education continues on the actual issue of concrete/other solid materials as a source of contamination from the activities that utilised Fire Fighting Foam with PFAS components.

The focus by Industry and their consulting advisors has been primarily on PFAS impacts to Soil and Groundwater contamination. These typically are not the primary source areas, but are secondary sources continually replenished from the ongoing runoff from the Fire Training Grounds and other locations where PFAS Foam has been utilized.

PROJECTS - Some Examples

Numerous early Research & Development (R&D) projects have been undertaken to develop and advance the PFAS encapsulation technology, now known as AMBIOLOCK. Early versions of the technology (Pre-AMBIOLOCK products) comprised a number of PFASencapsulation solutions, that were trialled with various application methodologies across a number of Airports, Fire Training facilities and Industrial sites. A selection of projects completed includes the following:

Surface Coatings pre-AMBIOLOCK products

Canberra Airport

Canberra Airport Fire Training Ground (FTG) – Samples of PFASimpacted concrete were collected, treated and subject to extensive laboratory testing to assess the performance of the PFAS encapsulation technology.

Hobart Airport Washdown Bay

Washdown area was treated with surface application to control the runoff of PFAS impacted water from the site.

Sydney Airport

This projected involved treatment of impacted and damaged concrete.

Industrial Site Victoria

Sizable PFAS impacted area treated impacted cores issues were noted from incomplete cleaning of the surface prior to application and interference of other contaminants (diesel) to ensure a proper sealing.

Brisbane Airport

Fire system suppression system test area was treated.

Sydney Testing

Rapidset Concrete Testing conducted to determine if Rapidset cement would see any unfavourable effects with the addition of AMBIOLOCK. Strength or curing time with the AMBIOLOCK inclusion to be same or better wth regards to curing times, strength of concrete created and ease of application.

Gold Coast Airport

Soil Stabilisation with an Admix application of AMBIOLOCK was conducted on various types of PFAS impacted soils (including sandy and silty clays) at the Gold Coast Airport. Testing results (for over a year since application) illustrated 99%+ control of leaching from stabilised soil with over 32 MPa strength created. Testing also indicated that could reduce the application of AMBIOLOCK by 50% and still achieving leaching control and strength (this indicates some real cost savings based on good pre-application evaluatons).

Melbourne Laboratory

Stress testing (particle size distribution studies) showed that PFAS leaching controlled even when AMBIOLOCK treated cores broken down to fine particles (this indicated longterm resilience of structures – beyond normal concrete and possible future disposal of deconstructed structures to low level landfills).

Co-operative Research Centre - PFAS mitigation control technology

Extensive testing of concrete cores with and without AMBIOLOCK application. Result indicated an assured advantage of AMBIOLOCK product in longterm controls of PFAS leaching, permeability controls, strength of materials, etc
