I live in Maryland. Here you can simply use a sharps container and dispose of it in regular trash pickup. I just buy the ones from Costco for a couple dollars each. Once it's full, just use the locking cap (I still tape it up), and put it in the trash can. Someone would have to work VERY hard to open it up. Once it's in a landfill it's no more dangerous than anything else that goes in there.
If I cut my finger while working in the yard and put a bandaid on it I don't need to think of it as some biohazard. I simply throw the bandaid in the trash. Once you protect the needles by putting them in a sharps container, 100 syringes have much less blood in them than a single bandaid, and are much less dangerous than a bandaid.
No sense in making things more complicated than they have to be.
