Mega worm bin

Everyone knows about worm farms. Mostly because folks get duped into thinking they can get rich raising worms to sell to fishermen. But a little worm bin is a nice way to get rid of some household garbage - old spinach, babana peels, etc.

There is no upper limit on this sort of thing. You could have really enormous worm bins. I propose that municipalities use technology similar to that used for oil tanks and water towers, and create giant worm bins. Yard waste would be ground fine, then fed to the worms. The more grass clippings and leaves, the more worms you will ultimately have. Tree-filled suburbs out east could have worm bins the size of sports stadiums, chowing down on leaves and grass. Agricultural plant waste could go into the worm bins as well.

These bins would produce quality worm castings, suitable to go back onto the soil. They would also be a source of safe protein in the form of luscious worms. These could be made into animal feed or deep fried for snacks (after a stopover in the cornmeal bin to rid their innards of gravel). Intrepid souls could go for a swim with the worms. Once a year, excess worms would be released from the bin in a televised ceremony.
