The Green Party has called for environmental awards made to East Sussex County Council to be withdrawn, over disputed waste disposal plans.
Plans for a rubbish incinerator at Newhaven were approved last week
The council received two Green Apple Awards from the Green Organisation for its Rethink Rubbish campaign last week.
But the Green Party said its decision to consider plans for an incinerator at Newhaven and a new waste tip in Eastbourne had "undone" any benefits.
A council spokeswoman said the awards recognised its work on waste awareness.
'Lack of planning'
The Green Party has written to the Green Organisation asking for the awards to be taken back.
Spokesman Clive Gross said: "Whatever benefit the Rethink Rubbish campaign has had in driving up recycling rates in East Sussex has now been undone a hundred-fold with the council's backing of these two schemes.
"Allowing the council to keep these awards will simply enable them to indulge in greenwash of the worst kind."
Plans for a rubbish incinerator at Newhaven were given approval by the council's cabinet last week.
The new waste tip at Tutts Barn Lane, in Eastbourne, is proposed in the Waste Local Plan, but the council said it had only been identified as a preferred site at this stage.
The Green Party said it believed both schemes were a result of "a complete lack of forward planning of waste management".
However, the council said it had set itself high reduce, re-use and recycling targets which went "hand in hand" with its plan to manage the county's 1.5 million tons of yearly waste.
