Protesters against a planned waste recycling centre in Wrexham have handed in an 11,000-name petition.
Plans for a waste incinerator were dropped after opposition
Portuguese firm HLC dropped controversial plans for a £25m waste incinerator two years ago.
But campaigners are against new proposals for waste disposal.
Wrexham Council has questioned whether the petition is representative and says new ways of ways of getting rid of household waste have to be found.
A public inquiry was cancelled after HLC abandoned plans for the waste incinerator on Wrexham Industrial Estate in 2003.
Local people had opposed the incinerator, mainly on health grounds, claiming there would be dangerous emissions.
The firm later unveiled an alternative plan for processing waste using pyrolysis (decomposition by heat) and gasification.
The Wrexham centre which would be able to handle 160,000 tonnes of waste a year would also need approval from the Environment Agency.
The Dee Borders Waste Action Group is behind the petition handed in at Wrexham Guildhall on Friday.
Their objections include the "lack of full assessment of risks and potential pollution, inappropriate location and the impact on the local economy".
Caroline Munro, the group's chairperson, said: "The people of Wrexham and the surrounding areas in Cheshire have given a resounding 'no' to HLC's plans."
Campaigners say that several companies on the industrial estate are already withholding investment until the application is decided, claiming it is jeopardising multi-million pounds investment.
The authority has to find alternative ways of disposing of rubbish
Andy Threlkeld, Kellogg's director and chairman of the Wrexham Industrial Estate Business Forum, said the companies thought the site was "an inappropriate last resort."
"It presents a threat to our businesses and any future investment, and is causing anxiety and controversy in the surrounding community of Wrexham and beyond," he said.
However, Wrexham Council said they were still waiting for an amended planning application from HLC.
And leader Aled Roberts questioned whether the petition represented the views of people in Wrexham.
"When questioned as part of the waste strategy survey 69% of our residents agreed with the council's strategy to produce energy through a thermal treatment process such as pyrolysis and/or gasification system before any rubbish is sent to landfill," he said.
"This was after recycling and composting as much rubbish as possible."
He added that the council was trying to extend kerbside recycling to all the town's 55,000 homes but that even then it will still face a problem with residual waste.
A spokeswoman for HLC said: "We've done quite a lot of work on trying to provide people with information and have been working closely with the council."
