Q. Large garbage containers that belong to a Jewish landlord, and they will be emptied only during Pesach, can the landlord place his own discarded Chometz into them on Erev Pesach.
A. If the waste containers belong to the landlord, he should also rent them out. Then he could place he's own discarded chometz before Pesach on them, as the containers and the property are not in his domain.
