That is the main function of the kidneys  -- maintaining the salt
balance in the body.  It comes out in the urine.

 Disposing of "waste" is a lesser function of the kidneys in the sense
that, if your kidneys don't work, you die from an electrolyte (salt)
imbalance before the miscellaneous wastes accumulate sufficiently to
kill you.
