Opponents of the Oneida Seven Generations plant concept demonstrate outside a December 2011 hearing on the proposal in downtown Green Bay.
The court fight over an alternative energy development on Green Bay's west side might not be finished.
Oneida Seven Generations Corp. said Monday it would appeal a court ruling that the company misled city officials about its gasification plant proposed at 1230 Hurlbut St.
Brown County Circuit Judge Marc Hammer ruled Jan. 9 that city officials properly repealed a permit because of the alleged misrepresentations.
In a statement Monday, Oneida Seven Generations said it "remains convinced" that the trash-recycling project would help the economy, create jobs and benefit the environment.
The plant would process household trash at high temperatures in a way that would divert waste from landfills and create a new source of electrical energy. Critics liken it to an incinerator and say it would harm the environment.
