This exactly sums up the problem. It's no use being able to recycle everything if doing so requires everybody to sort their waste and take it to different places. Most people won't do that. If we remove single use bags and cling film (yes, cling film is going to be a tough one), you're no longer reliant on the consumer to responsibly manage their waste. There's a trade off. You're no longer sorting waste, and you're still generating less waste, but reduced shelf lives mean you now need to shop for fresh produce more often, potentially using more fuel and offsetting any gains. But you're no longer producing waste that takes centuries to decompose.
