Like every year, one should make sure to clean his bins, and make sure no chometz is thrown inside. If one owns bins together with a non-Jew or a Jew who doesn’t keep Torah and mitzvos, and isn’t careful about chometz (and this year, even those who keep Torah and mitzvos may accidentally put in chometz on Shabbos morning) and it is likely that chometz may get thrown into the bin over Pesach, he should make sure to relinquish his rights to the bin/bins in front of three people on erev Shabbos before the time of biur chometz (one shouldn’t wait until Shabbos morning, as ideally we aren’t mafkir things on Shabbos, and ideally one shouldn’t even wait until just before Shabbos either, as we try and do biur and mechiras chometz the same time as every year to avoid confusion). Although one continues to use the bin/bins after he was mafkir it throughout the duration of Pesach, it is not considered as if he reacquires it, since the neighbours aren’t particular about him using their bin [Shu”t Betzel HaChochma (3:109), and Shu”t Teshuvos V’Hanhagos (1:289 and 2:211:11)].
There are some pokim who are lenient and say that one doesn’t need to be worried about chometz inside the bin. They hold that since the chometz is not fit for eating (although sometimes people put chometz inside a bag in the bin, and in such a case it is suitable for eating, we can say like the Teshuvos V’Hanhagos 2:211:11 that the reason behind the obligation of biur chometz is because one may come to eat the chometz, and in a case of a bag inside a bin there is no concern, therefore, there is no need to get rid of it, especially if it isn’t yours), and the bin acts a mechitzah [partition], there is no need to be mafkir the bin.
