Vehicles used by businesses to illegally dump waste, including asbestos, could be crushed under a proposal being considered by the South Australian Government.

Environment Minister Ian Hunter said the suggestion was made by the state's waste industry at a recent summit.

"We asked the waste industry to come up with ideas on how we can improve recycling and avoidance of waste, but also how we can crackdown on the cowboy operators in the industry," he said

"One of the solutions that came from the industry itself is if you have a conviction in illegal dumping, then you seize the vehicle that was involved and crush it like we do under hoon licensing now."

Mr Hunter said the idea was aimed at discouraging business operators from illegally dumping waste.

"It's a significant impediment to carrying on your business if your vehicle is taken away and crushed," he said.

"These will be vehicles that were used in illegal dumping but there must be a conviction, of course, through the courts.

"This is another weapon, I suppose, to discourage illegal dumping."

Mr Hunter said the Government would canvass industry and community support on the idea.

Last week, tonnes of dumped waste which included asbestos, was left on former defence land owned by Renewal SA at Osborne.

The material was quickly removed from the site which is, at times, used by anglers and dirt bike enthusiasts.

An emergency response team from the Environment Protection Authority (EPA) gathered evidence from the site in a bid to identify the culprits.

Authorities said there were up to five tonnes of building material dumped, some of it in plastic bags labelled as asbestos.

A spokesman from the EPA said he was confident there had been no risk to the public from the illegal dumping.
