But I'm taking about having big trash bags piled on the street for 12+ h practically everyday. For instance, an easy solution would be to put them only 2-3h before the trash trucks come (I've seen them before the last train at ~11pm, the truck comes at 9am). A cultural-change would be to have big metal containers to put the trash away so that animals don't have an easy way in.
