Protesters are expected to gather tonight at a meeting to discuss plans for a new biofuel plant outside Brighton and Hove.
The £20million power station in Shoreham will run on plant oils and animal fats. However, concerns have been raised over air pollution and the smell it could cause.
A planning application for the plant, which could provide electricity for 18,000 homes, will be considered at a meeting of Adur District Council at 7pm.
