Councillors were set to meet to consider whether to adopt the waste plan as Planning went to press. But Friends of the Earth (FoE) and environmental groups Dump the Dump and Defenders of Ouse Valley called for a fresh inquiry into the plan.
They claim that the current version is flawed because it focuses on waste incineration in Newhaven. The groups also object to the Hollingdean depot being used to transfer waste outside Brighton and Hove.
The plan was scrutinised at a public inquiry in 2003, when the inspector recommended a number of changes. These included managing as much waste as possible in the city and ensuring that it is recycled and composted by 2015.
But the campaigners believe the recommendations have been ignored. FoE South East spokeswoman Brenda Pollack said: "We want to see a recycling-led strategy, not an incinerator-led one."
But a council spokeswoman insisted: "Recycling targets set in the current plan already exceed government targets."
