In respect of the supermarket issue, I do find the criticism ironic, really, given that most of the waste streams that we're trying to deal with actually come out of supermarkets in the first place. So I don't have too much of a problem making it convenient for people to return their containers when they're going to the supermarket. When they've got them in their boot they can take them and put them into a reverse vending machine in large supermarkets. It won't happen for every supermarket but we know from overseas experience that the success of these schemes depends in part through the convenience of the return venues that are accessible to people that want to return their containers.
