People in Cardiff are generating a rubbish mountain and there are fears the city is struggling to meet waste management targets.
Household waste increases by 5% every year in Cardiff
A council report says that waste levels increase by 5% every year, while the city's main tip could be full by 2010.
Cardiff council is working on a 10-year plan and a public consultation has now been launched.
Plans include a £4m recycling plant to sort waste 10 times faster than the current facility.
There are fears that Welsh Assembly Government targets for reducing waste dumping on landfill sites will not be met.
A report compiled by the council admits that the targets set by the assembly government for 40% of waste to be recycled or composted by 2010 will not be reached through its existing schemes.
New technologies could be introduced to deal with the problem of rubbish which cannot be recycled.
This includes Mechanical Biological Treatment (MBT) - a process which treats waste by allowing it to degrade by a biological action which in turn produces a dried organic material which can be burned to produce power or buried in landfill.
Friends of the Earth have said that the process has its merits but fears that the local authorities who adopt it will only dispose of the waste via incineration, which they say will lead to pollution.
Julian Rosser from the campaign organisation said: "There is nothing wrong with MBT in itself but we are worried that the treated rubbish produced will only be disposed of through burning.
"This will lead to pollution, even though incineration has improved from what it was 20 years ago, we are worried."
But the council has said that the process is just one of a number of options being considered.
The council wants to reduce the amount of waste being buried
It has said that by 2008, all households in the city will be able to take advantage of a free kerbside recycling collection - currently some households have to buy the green bags needed to take part.
The city tip has an estimated life span of another five years before it reaches capacity and the council said it was important that householders change attitudes to disposing of waste.
A £4m Materials Recycling Facility (MRF) is in the process of being constructed in Cardiff which will be one of the largest publicly owned facilities in Europe.
It will sort through 60,000 tonnes of rubbish each year - operating 10 times faster then the current facility.
Elgan Morgan the executive member for environment and transport said: "We want residents to think green when disposing of their waste."
A public consultation into how to tackle the problem of waste in the city has been launched, starting with a survey in the council's newspaper.
