The Castle Leisure Centre opened at Elephant and Castle last year and I have been to the pool there many days this year. There are bins throughout the centre, with recycling ones next to general waste bins. I've been amazed over the months at the failure of people to sort their rubbish. Those people who bother to put empty shampoo or water bottles in the bin seem to do this randomly, about half go in the bin labelled plastics and half in the general waste bin adjacent.
At Taunton station last week I saw the clearest attempt I have seen yet to help people simply sort their rubbish.
Every waste bin has one recycling bin adjoining it, and clear directions are given on what to put where should you be in doubt.
