I suspect most of Milton's got the blue bins by now. From what I read in the last South Cambs. magazine, we're not expected to put the things out for collection until the first green/blue day after October 11th, which based on the present schedule will be Tuesday 19th October (and there'll be a new South Cambs. magazine with new timetable before then). So it'll be "continue with green/blue box" until then. I've been stockpiling plastic since I knew the blue bins were coming, so at least I'll be able to start filling it up now.
