More than 550 people have joined an internet petition against Gloucestershire's planned incinerator.
The £500 million burner, which would be built at Javelin OPark, in Haresfield, needs planning permission next month if it is to go ahead.
Campaigners are hoping the petition will be another reason for county councillors to refuse the plans.
If it is built, it will deal with Gloucestershire's waste which is currently sent to landfill.
The petition is at http://epetitions.direct.gov.uk/petitions/43257.
