We are shocked and horrified at the footage. A lot of hard work has gone into preparing the new scheme and residents have been diligently separating their rubbish as we asked. To then see this happening is completely unacceptable and we are very sorry.
We are having urgent discussions with Serco to investigate what their staff have done, which we strongly hope is an isolated incident. If there is any disciplinary action or retraining of staff required, we will insist that this happens as a priority. And clearly we will be looking at what we pay Serco in these circumstances."
