it goes to the sewer system which needs to be able to take care of things anyway. The amount of waste water through a RO system insignificant - your toilet flushing needs will use more water than your RO drinking water needs. (a typical low flush toilet, though some camping toilets use less)
Haven’t looked at them in a while, but I know the aquarium ro filters produce 1:1 waste: water. Could certainly be more efficient now, but I haven’t researched in a while

there are different systems with different efficiency ratings. However even the worst don’t use much water - you don’t drink much water in a day.
