Or, you could be even more efficient and you could pulverize the bones, then use the Automatic Crafting Table MkII Minium Stone trick to duplicate your bonemeal. Here's how:

Pulverizer --> ACT-MkII (turn bonemeal back to bones) --> Loop back to Pulverizer

This doubles your bone amount each revolution. All you need is a steady source of MJ and one bone (to start the system). Very simple and useful.

This also works with Blaze Rods/Powder and any other material which can be pulverized/macerated (and produce extra output) and Miniummed (new word!) back to its original state.
