Families in part of Gwynedd may suffer under new plans to cut the amount of rubbish they can put out for collection, a councillor has claimed.
Householders in Dwyfor will be charged for excessive rubbish
The Gwynedd Council scheme comes into effect next month and will allow only one wheelie bin full - or three black bin bags - of rubbish per home.
Opponents to the scheme claim this could encourage more fly-tipping.
But the council said it wanted people to take advantage of a range of recycling facilities within the county.
Waste management within the county is a top priority as the present landfill site at Cilgwyn near Caernarfon, which receives rubbish from thousands of homes in Gwynedd every week, is due to close in 2008.
Under the new scheme householders in Dwyfor will be allowed to pay if they have extra rubbish to dispose of, and could face fines if they "dispose of waste unreasonably".
Many councils are examining their waste processes, with new laws aiming to raise the amount of recycled and composted waste from 20% to 46% by 2010.
Research has found half of Welsh councils either already collect waste every fortnight, plan to, or are considering it.
The assembly government has an aim that by 2026 no additional household waste will be put into landfill sites.
Councillor Steve Churchman, from Garndolbenmaen, said Gwynedd had put "the dustcart before the horse" by putting new rules in force before they sorted out the doorstep collection of cardboard and plastic.
"I'm very much in favour of recycling but I feel the council is penalising people who might not have the means to either pay extra to have their extra rubbish removed, or have a car to take it to the local tip.
"I feel there's no way at present for larger families to be able to cope with just one bin, and it will lead to more fly-tipping, which is the last thing we want."
According to the council, the change is needed to meet its recycling and composting targets of 25% in 2006/07 and 40% in 2009/10.
The scheme will be phased in gradually throughout Gwynedd, beginning in Dwyfor on 20 November.
Gwynedd councillor Owain Williams, whose ward covers a composting facility in Clynnog Fawr, welcomed the move.
"The worst problem in Gwynedd is plastics at the moment and we must work to cut down on the number of landfill sites," he said.
A Gwynedd council spokesman said: "Currently Gwynedd residents are succeeding to recycle 24% of their municipal waste, which is a very encouraging figure."
"The council's recycling collections will extend to include the collection of plastic over the coming months."
