Veolia Environmental Services claims that the North Quay plant will generate electricity for 16,500 homes by processing 210,000 tonnes of waste from East Sussex and Brighton and Hove.
Earlier this year, former communities secretary Ruth Kelly said she would not call the plan in despite a large number of objections (Planning, 30 March, p3).
A ten-day public inquiry is now in progress to decide whether Veolia can compulsorily purchase land to bring the scheme forward. Local campaign group DOVE2000 is challenging the move.
An East Sussex County Council spokesman told Planning: "The committee took into account that the Environment Agency said the facility will not damage the environment or harm human health and that the site has been identified in the local plan as appropriate for such development."
Meanwhile, Staffordshire County Council said it is considering plans for a waste plant as part of its drive to landfill no waste by 2020. Warwickshire County Council dropped plans for an incinerator last month and aims to send more waste to the proposed Staffordshire plant (Planning, 26 October, p5).
