I love this idea and I will look at implementing it this weekend!
This is the best discussion I've read about 'Trench Composting'-- LINK. --offering different ways and means to bury your scraps.
I'm going to start experimenting with pouring occasional doses of the weed tea that I've been brewing for some time. Its made from rotted Wandering Jew (or Trad Tradescantia albiflor).
Roughly, I've buried each bin/tower in beds 3x 2 metres. With the assumption that my Vetiver -- once consolidated and deep rooted --will contain the bed like a bathtub wall.
"Whenever I am not satisfied with the performance of a bed, I can usually turn things around by peppering it with cathole compost holes filled with autumn food preservation waste, and then covering it with a biodegradable mulch of chopped leaves. I use holes rather than trenches because more soil is exposed to the gazillions of microbes that turn food waste into soil organic matter. When the holes are spaced about 18 inches (45 cm) apart, the columns of soil between them become havens for decomposers from big earthworms to the tiniest bacteria. When the bed is tucked in with a thick blanket of mulch, the stage is set for slow soil-improvement miracles." -- Barbara Pleasant
As for kitchen management protocols...We use a couple of stew or oven pots with well fitting solid glass lids. One is for the the chooks -- the other for these wormery towers. Both are around 1.5 litres in volume.
They sit on the counter and are emptied at least every other day. If you use a porcelain container or a high quality stainless steel pot, these pots are easy to clean. The trick is the heavy glass (so that you can remind yourself to empty) lids.
Since the hole has already been dug --it's as easy as visiting the outdoor rubbish bin.
The only self evident proviso is to watch the salt content of the stuff you bury -- especially if you have heavy soils.
In general practice ALL BIODEGRADABLE WASTES exit the kitchen this way --although much of the paper packaging, all the plastic and the glass ware goes out thru the council recycle bin.
The cage mesh wormery has been so successful that I've -- we have -- doubled their numbers.
In this age of NO PLASTIC BAGS when shopping about, at home here we adjusted our habits and all the biodegradables go into the soil outback.
It seems a crime to put at the council bin every week.
At the school garden we are burying all the scraps from the School Tuck Shop as well as the weekend breakfasts held before school.
My dogs leave the towers alone as they cannot access whatever is in them -- even if they fancy the menu. No rats. No invasive mice. Just a few sneaky fruit flies.
I'm burying vegetative matter, bones,cooking scraps, paper and cardboard, slops...whatever.
Thus far I have had no cause to add extra stuff in way of 'browns and greens' . This is about rotting, it is not a composting ritual ruled by churned biochemistry. Mainly anaerobic.
The stuff rots in situ. If, and when, the hole fills up with rotted stuff (aka compost) I have the option of pulling the frame up and burying the cage in another section of the garden. In the meantime the assumption is that garden microbiology and earthworms will share the composted material about the beds as each bed these wormeries occupy is not very large.

Vetiver grass helps to stabilise soil and protects it against erosion. It can protect against pests and weeds. Vetiver is also used as animal feed. (Wiki.)
GrowVetiver is a plant nursery run by Dave & Keir Riley that harvests and grows Vetiver grass for local community applications and use. It is based in Beachmere, just north of Brisbane, Australia.
