Vermicomposting Toilet Question

Save yourself the time and money. Shit in a bucket and throw sawdust on it. It's absolutely life changing, costs 0 dollars and yields truly excellent compost.

I installed a Dowmus (worm farm) system (NLA) about 30 years ago. Unfortunately the filter membrane blocked and the pile became anaerobic. Rather than empty the tank and start again I added a supplementary drain to a trench under an ornamental garden which has resolved the problem, though I'm yet to get anything like compost out of it. The extraction system is inadequate so I extract with a trenching shovel and compost in a sealed compost bin for a couple of years. Even with all that, it's the best/nicest toilet I have ever used.

Yes.

Longer answer. Worms drown, the leach field/drainage prevents water pooling at the bottom of the outhouse.

The common method is to throw woodchips/sawdust/biochar.

Yes, I have two vermicompost toilets and both have worked flawlessly for 5 years. Best system ever.

I installed an old toilet outside my house on a built wood base. What I produce gets put into a IBC tote within minutes. Not realistic for methane production but in less than a month (Sunmer soon), I have the perfect biosolids to cut my bamboo biochar! Learned this technique from a huge compost operation in Fredericksburg VA. Owner has a massive portajohn operation and cuts the tree waste with the biosolids. As long as each step is followed, your sphincter is producing Black Gold.

Worms don't make compost nor do they destroy pathogens. Vermicompost is a misnomer.

If your compost doesn't heat to mesophilic and thermophilic temperatures it's not really a compost and in the case of human excrement poses a health hazard.

You should probably do some more reading on the matter since improper sanitation measures can be dangerous.
