How to Make a Vermicomposting Flush Toilet

It seems I have built at least one "Vermicomposting Flush Toilet" and we have another one that was already in place. Though from monitoring it seems there are at least in one Anoplotrupes stercorosus or alike who take care of cleaning up. We do not put toilette paper or alike inside but in a separate bin. From times living without a toilette in a forest I can remeber, it was not really needed to dug a hole and afterwards cover it, as those friendly beetle tend to sense their primary food source out of quite some distance (they can fly - not that great but much better then walking) and below 24h 100% was already gone. Of course toilet-paper was extra handled.  Without those beetles composting would perhaps take long time on an acid forest soil?

I had never really thought how nature solved the problem with all those excrement in a forest, as I had never seen some, only toilet paper. One great thing about those toilets is, they do not smell, never get full, thus needing very little to zero attention. That is what I dislike very much about compost toilets, even if it doesn't smell that much, one has to empty them sooner or later, better frequently, which is a pita to me.

Based off of this design i have started to build my own vermicomposting flush toilet in Australia. We have extrem temp fluctuations.
I'm documenting the build and will continue with updates once completed to see how it goes over time.

Any comments or tips would be greatly appreciated.

Mike Homest:

Can you share some pictures or other design specification on your beetle toilet? I am highly interested!
Where about are you located?

I have always thought of vermicomposting as an end-stage of such a process.

I think mine will start with a greywater-supplied low-flow toilet, to minimise unnecessary liquid additions. I think if I had a need for it, I would run that slurry through a methane digester.

I want to dewater after that point. Ideally, I would pass the black water through a sand-filter raised bed, fitted with a cold-frame during the cold months and situated in a hoop house or lean-to greenhouse that would be open/vented during the hot months.

The filter bed would be planted in heavy-feeding perennials and self-seeding annuals, though I don't know that I would necessarily want edibles growing out of it. I would probably set it up to grow chicken forage and pollinator food and habitat. It would also be treated regularly with oxygenated compost extract and fungal slurry.

There would be a drain at the bottom of the opposite end of the bed, and that would take the filtered effluent to a swale running on-contour above heavy-feeding tree species downslope of it. The leaf mulch provided by the trees would make leaf litter, leaf mould, and carbonaceous materials for composting.

As to the remaining solids, I would first use a Black Soldier Fly Larvae decomposition process, as they seek out feces on their own, and more readily than composting worms. Moreover, while red worms don't like the enzymes that black soldier fly larvae produce, once those enzymes have dried, the worms love the BSFLs leavings.

The BSFL bin, to which the solids would be transferred, would have a larvae chute leading to a central "sacrificial" compost feeding area, where the chooks would gorge on the larvae.

I would move the solids left over from the BSFL process into a raised bed, perhaps even the same one that contains the sand/fungal/bacterial filter, or one like it in the same greenhouse.

When the worms were done with it, I would be fine topdressing food crops with the worm castings.
