Esposito, who lives in Kensington, said he does not believe Philadelphia residents litter more than people elsewhere. Rather, he repeated a phrase he’s heard often: “The dirtiest day in my neighborhood is the day after trash day.” In other words, he said the city’s blue recycling buckets, first issued to residents years ago, weren’t made for the explosive increase in plastic, and don’t have lids, so their contents often spill onto streets.
