        THE ANSWER TO MELBOURNE’S CONTAMINATED SITES?


The largest soil decontamination project in Australia – and only the second clean up

of its kind in the world using the unique thermal desorption technology - will be

unveiled:



When:  Thursday, December 11 

            At 10 am


Where: 917 Princes Highway 

             Springvale (Near Westall Road intersection.Proposed site of the Harvey

            Norman/IKEA $300 million homemaker centre. The largest in Southern

            Hemisphere).



This unique technology – endorsed by the Victorian Government and the EPA - could

also be used to clean numerous contaminated chemical, manufacturing and petroleum

sites around Melbourne. 


The process avoids taking contaminated soil to landfill, is cheaper and causes minimal

disruption to neighbouring properties. 


More than 20,000 tonnes of contaminated soil is being treated on the eight hectare

Harvey Norman site at a cost of $6 million.


The contaminated soil is being cleaned and neutralised by the Australian company

Innova Soil Technology using its Direct Heated, Fast Quenched, Thermal Desorption

(DFTD) process.


The process cleans the soil of hydrocarbon contaminants (Polychlorinated Biphenyl

or PCB) by heating the soil in a rotary dryer to almost 500 degrees until the

contaminants are vaporised and reduced to an “undetectable” level.


The evaporated contaminants are then heated to almost 1000 degrees and converted to

harmless carbon dioxide, water and a small portion of acid gas, which is then

neutralized. 


The decontamination has been undertaken on a 24x7 basis cleansing an average of 15

tonnes of soil an hour since the plant was established on site in the mid year.


On completion of the decontamination early next year the site will be removed from

the Victorian EPA Priority Site Register enabling the $300 million construction of the

largest Harvey Norman site in Australia to commence.


Mr. Bruce Dawson, EPA executive director regional services praised Harvey Norman

for the remediation of the site although they were not responsible for the original

contamination 


“On-site treatment means sending less contaminated soil to landfill,’ he said.


(News Directors/Pictorial Editors please note: The process incorporates the

contaminated rubble and soil being excavated and loaded onto a conveyor belt before

moving into the heating drums. Fifteen minutes later it cascades out of the feeder as

clean soil, which can be immediately handled. Quite graphic. KD)
