Yep, my clients do so too as CJ says.

If your qustion intends asking where to put it finally check the safety data sheets of the respective product. I can tell you for powdererd cement based addy:
"Cement based tile adhesive waste, as powder or hardened, is to treat acc. to the european waste catalogue waste key 170101 for concrete waste / cement based building rubble / cement construction waste."

My clients either have a waste container and/or bring it to the local waste disposal site.

I have one "rubbish" bucket. I empty any residue adhesive into that and next morning throw it in the bin with the rest of the crap.
