Can you recycle cigarette butts & ash?

Cigarette filters are a single-use plastic and the most littered item on earth — they never go in recycling. Make sure ash is fully cold before binning. Vapes are a completely different (battery/fire) problem — see vapes.

Which bin does it go in?

Cold ash and butts in general waste — butts are plastic (cellulose acetate), not paper.

Before throwing it away, see reuse, repair and donation routes.
