I don’t add bones. But things like paper do break down well. I add bits here and there to my Bokashi bins- things like napkins, bits of cardboard etc. I throw in avocado pits and peels too.
Here is sort of the long winded description of my process:
I have four Bokashi bins on my back porch. I have a large plastic yogurt container on my counter (or in my sink) for veggie scraps plus paper. Note that I keep the size of things to about 2”. When that gets full. I take it to the back porch and open up the available Bokashi bin and add the material, using an old potato masher to compress it. I throw in a toddler size handful of the Bokashi bran, put the piece of paper bag back on top (torn bag that fits the opening, helping to keep things anaerobic). Close bin. Once a bin is full, I move on to the next one. When I get close to having all 4 bins full, I take the oldest 2 out to my 2 active compost bins outside and add them on top of each. Then I rinse the Bokashi bins out and put the empty ones at the ends of the line.
In the summer when I have a lot of material in the yard, I tend to use two of my outside bins as hot compost bins- I’ll add a bunch of layers all at once and include a Bokashi bin in each. It takes about a month for those big compost bins to break down completely. I also have two other identical bins to throw stuff in while those two are cooking. I have chickens so I always have tons of green and browns between their litter and the yard waste. (Their poop board uses shredded paper).
Anyway, by the time the hot compost is ready, those avocado pits are crumbly. They’ve been through the Bokashi process and the hot composting process.
(I’d personally tear apart that egg carton, and for me, corn cobs go to the chickens, then into hot compost.)
I use a lot of paper- I’m not afraid to put it in either the Bokashi bin or the compost pile. As long as you’re adding greens and browns in some layers, it should easily break down.
