Where there was a stack ...

Almost a week after the stack's demolition, rubble remains strewn across the Port Kembla Copper industrial site.

And it could stay like that for a lot longer.

A Port Kembla Copper spokeswoman said the disposal of the rubble could take up to three months to complete.

"Rubble will be tested and disposed of in accordance with waste classification guidelines," she said.

"This may include reuse as inert fill on site, depending on the results of characterisation."

Initial results concerning composition of the dust plume from the demolition have been released on PKC's website stackinfo.com.au and the company spokeswoman said a more comprehensive report would be released next Wednesday.

Following the demolition, PKC said no evidence of dust impacts were detected to the south-west and southern areas of the exclusion zone, but some was deposited to the east and south-east of site.

Meantime, PKC has confirmed it has received serious bids to buy its Port Kembla site.

However, the company refused to comment on specific details "until arrangements have been firmed up".

PKC general manager Ian Wilson has in the past said the site could go for as much as $30 million, or as low as $10 million.

Last Friday, Mr Wilson told the Mercury various groups had approached him wanting to either purchase the entire site, purchase parts of the site, or enter into a lease arrangement.
