Members of Newark & Sherwood District Council's planning committee said they could not support proposals by Veolia Environmental Services for the facility at the former Rufford Colliery.
Their decision to object to the plans came after a protest this morning by members of People Against Incineration (PAIN) at a site visit by councillors, where campaigners released black balloons to show the carbon footprint the incinerator could have.

Local residents turned out in force with banners to make their views known about the plans and the protest went ahead peacefully, although police were called to the scene.
Planning officers at the district council recommended committee members object to the incinerator because of concerns about its carbon emissions and building the facility on greenfield land.
The authority will send its views to Nottinghamshire County Council which is expected to make a decision on the plans next month, although the decision could then be called in by the Secretary of State for a public inquiry.
