NAPPIES and other disposable hygiene products will sit in Lake Macquarie bins for up to a fortnight after 2015-16, under a city council plan.
The proposal has raised concerns that residents will be bothered by odours, particularly in summer.
Jennifer Thompson, director of a Morisset child-care centre, said her centre went through 600 nappies a week.
Ms Thompson said the centre could not cope with fortnightly nappy pick-ups.
‘‘The council will have to do something about it,’’ Ms Thompson said.
Cr Brian Adamthwaite said the council would find a solution to the problem before 2015-16.
‘‘I don’t expect nappies will sit for two weeks in bins,’’ Mr Adamthwaite said.
Nappies and other hygiene products will be collected weekly, as normal, in general waste bins until 2015-16.
Beyond that the council’s general waste bin will be collected fortnightly because a new third bin will take organic waste.
A council report said its ‘‘preferred solution’’ when that happened was to collect nappies and other hygiene products fortnightly in the general waste bin.
It planned to lobby government and industry to use ‘‘biodegradable absorbent hygiene products’’.
The report said the council considered a fourth bin for hygiene products, but judged the $19.2million a year cost too expensive.
Collecting hygiene products fortnightly in the general waste bin would cost $18million, but weekly collection in the planned third bin would cost $17.8million.
However, the government does not allow such waste to be composted, so the council cannot put them in the third bin.
The council plans to lobby the NSW Environment Protection Authority to grant an exemption.
Councillors will vote on the matter tonight.
