It keeps the critters out of scraps if you have a bin to keep it in until it breaks down & can be composted into the ground, from what my DH told me. He insisted we have a tumbling composter, & he is the KING of frugal when it comes to that stuff, but said something about the right ratio of oxygen to break it down... & it can break down rapidly in a bin that is being tumbled regularly.
I want to make a worm bin too... baby steps though... as we already have the tumbling composter because DH got as super deal on it last year.
