A public inquiry into controversial plans for a waste incinerator on the outskirts of King's Lynn begins today at the town's Corn Exchange.
Norfolk County Council has agreed a 25 year contract with the Cory Wheelabrator company to burn 170,000 tonnes of household waste each year.
It maintains that the plant will be built on an industrial site and will use proven technology that is widely and successfully used across Europe.
The council says the project will stop waste going to landfill and generate electricity.
Opponents say the proposals are environmentally damaging and socially unacceptable.
They say there are proven technologies which are better than incineration which can also produce energy with significantly less pollution.
Lawyers representing the various groups being represented at the inquiry will today outline their cases to the planning inspector.
