Controversial plans to build a waste processing plant in south Liverpool are to go before a public inquiry later.
Jack Allen Holdings wants to build the plant at Garston Docks to process commercial and domestic waste.
Liverpool City Council has already rejected two planning applications for the plant, which would handle about 150,000 tonnes of waste a year.
Local residents have objected, saying it will create noise and traffic problems in a residential area.
Jack Allen Holdings has said the resource recovery facility would provide a solution to a growing waste crisis on Merseyside.
The firm's initial plans were revised after concerns were raised by local residents.
The height of the building was reduced and plans to treat the fibre product from the recycling process on site were scrapped.
Jack Allen Holdings lodged an appeal with the planning inspectorate and the public inquiry is due to start later.
