When desoldering (how else is a true DIY hacker supposed to get free parts...) one always has the problem of where to put the little bits of solder that get removed. A handy commercial desoldering pump is great, but it needs to be cleaned out. One could flush it onto the bench / floor (as I have done for too many years), or one could take time to walk to a trash can, but I discovered a better idea. Using a handy plastic gum tub! The little door is just right for inserting the nozzle to dump. When it gets full, I can take it someplace to be properly recycled.
