Pour it in a proper waste container with a label and hand it over to EHS if in a lab. If not, do what another commenter said and let small amounts evaporate in a well-ventilated place.
Large volumes are something you should contact local waste disposal about. This usually isn’t free, but sometimes they have certain times of year they’ll take them for free. Large volumes are ~ >1L.

Acetone evaporates quickly. You just let it sit for a minute and it’ll dispose of itself

so just inhale it all… ok

Our hoods have a solvent trap at the front in case of large spills, it’s a stainless steel grate covering a large, high surface area secondary steel trap below. Ngl, I pour smaller amounts of pure volatiles in there to evaporate. Usually < 10 mL. Small volumes with dissolved solids get dumped in the glass waste container in the hood to evaporate before disposal too.
Not the best practice, but the pragmatic approach.
Larger volumes go to proper waste containers. Local EHS mostly just dilutes things before pouring it down the drain. Not much we can do about that, so I opt for greener solvents from the beginning wherever possible.

Yeah, I don’t work in a lab, but if I clean something in the shop with Acetone, I leave the rag to dry on the side of the trash can. If I think it’s a lot, I’ll put it outside to evaporate or burn it.
