Worms and Kitchen Garbage

I've been bringing worms to school for the last 7-8 years to share with the short people for science. Three years ago, I found a small and simple worm box on Ebay, cheaper than it would've cost N to build. Much easier than going out in the rain every November and digging through our compost to look for worms. I'm not a champion worm box owner, but I do give them a level of care that keeps them alive and multiplying.
One of my co-workers recently moved to a larger home that leaves little of her property left for a yard. She told me that they no longer had room for a compost pile and wanted to know if a small worm box (like mine) would be able to take it's place - for kitchen garbage, not grass and leaves. I told her that if she produced the amount of fruit, vegetable and coffee ground garbage that we do, there's no way the worms in a small box could keep up.
More co-workers joined the discussion and one wondered out loud if our yard debris containers would be a suitable replacement. None of us knew for sure, but it made perfect sense. Since then I've gone to the county website and found out that kitchen garbage is on the list of acceptable debris that can be put into "big green/grey".
Good news for people who feel they don't have enough room in their yards to compost and good news for people like us with dogs who like to mine the compost for kitchen treasures!
