Get your own trash can.
Or, send an email to Dan saying that you will empty the trash can every other day. He will empty it on those other days. CC the email to your manager. If he doesn’t empty the trash on his days, empty it in a garbage bag, and leave it their for him to do, so the trash can should start off empty on your days.
People have more respect for those that stick up for themselves. Even if at the beginning it looks like they don’t.
