It seems so obvious when you see it - the Urbano trash bin that can be used with plastic bags you bring home and might otherwise discard. Many people already reuse bags to house their recycling or even their garbage but this design makes it even easier and cleaner to do so. They are not exactly high style but certainly look better than leaving bags of recycling lying around.
Another twist to make this design even more compelling: extra bags can be stored under the one in use, pushed down by the handles and tucked beneath them. Replacing the bags, then, is even easier than in a traditionally designed trash can - you just pull up the new bag after your remove the old one and hook its handles around the catches provided.
