More voices have been added to calls for the Tasmanian Government to deal with a growing pile of discarded car tyres.

There are about 1.3 million tyres covering 20 acres at Tasmania's only tyre recycling plant in Longford, and the pile grows by about 400,000 a year.

It has been set on fire several times in recent years, and locals say with the size of the pile now, the next fire could be devastating.

Independent MLC Greg Hall is introducing a notice of motion to put pressure on the Government to pay for a tyre processor.

Northern Midlands Mayor David Downie says that there is strong interest from private companies, but the council can do nothing without a planning application.

“In the last four years we've had three proposals that haven't actually come to fruition,” he told reporters.

“People are talking - we want to see them actually walk the talk.”

Mr Hall said the Government must start working with the Northern Midlands Council.

“At the moment, the tyres are all stored here and therein lies the problem,” he said.

“To move them off the island attaches quite a cost to it. If we could have a small industry set up here it would provide local employment and sort out this problem.”

Mr Downie said private-sector processing firms could become more interested if the Government introduced a levy on new tyres to pay for the disposal of old ones.

“They need help from the State Government to have a charge set when people buy new tyres,” he said.

“They should pay a levy to help with the disposal of their old tyres.”

The Government has pledged to meet with the council later this month.
