There's not much leftover, as they are served in small little sauce-like plates. It's pretty frowned upon to ask for more banchan if you aren't going to finish it.
A substantial restaurant meal in Korea is usually served with several standard side dishes. Due to the expense and effort of providing these to each table, restaurants often require a minimum party size of two. Also, I'm not sure if it's illegal or just gross, but if a dish looks untouched, sketchier places will sometimes just pass it along to the next customer.

But yes, the leftover dishes are thrown away.

Usually there isn't much. The plates are tiny and mostly have vegetables.
You eat them.
