Astronauts often stay more than a year on the ISS, they produce trash like any other human. Is there like a limit that they may produce ever day or maybe some measures were put in place to reduce the amount of trash produced every day?
The obvious natural limit on amount of trash comes from the law of preservation of mass: they can't make more trash than the amount of material that was delivered by a delivery spacecraft with a resupply mission. They pack all the trash into bags kept for that specific purpose, and when a cargo spacecraft is to undock to be deorbited and burn up in the atmosphere or land, it's loaded with all the accumulated trash, which then subsequently burns up in the atmosphere with the spacecraft or splashes down on Earth. (and obviously since it all fit on the way up, it fits on the way down.)
