You should post that to "ideas!" What an excellent way to move your worm composting around without having to dig each time.
When I first started my little garden strip (I live in a condo too), I buried a lot of kitchen scraps. When I dug the area up the following spring, there wasn't even a hint of those scraps left!
Yes, Mac is right according to what I've read. Worms eat eggshells and it helps them to clean out their systems. I grind mine up using a regular drinking glass and a cutting board. But I've also used larger pieces of eggshells in my garden to deter slugs. It seems they don't like to creep over the sharp edges, and then the garden worms can eat them too.
