I'm wondering what the benefit would be to composting anaerobically, since the vast majority of organisms that aid in decomposition metabolize oxygen.

I'm reading that for bokashi, the solids that are in the barrel have to be buried/composted for at least two weeks before that area can be planted, if not the plants can be damaged.
If I'm doing an anaerobic composting bucket (like the video of David the Good linked up there), do the dregs on the bottom also damage plants if I use them for mulch, for example? Similarly, if I don't let it ferment long enough, will the liquid I drain out hurt my plants? (sorry for lack of better terminology, I am not clear on whether the damage is because this stuff is too "hot" or what).
I was going to move to bokashi/swamp bucket for my kitchen scraps because during the summer I quite simply don't have a bed I can use as a compost pile or to bury waste. If I have to bury the solids anyway, I'm not entirely sure how useful this system is going to be. I'm not sure if just blending all my non-rabbit-food kitchen scraps and mulching my plants with it would be better, worse, or the same as mulching with this bottom sludge.

But I've seen some people do some pretty funky things with anaerobic composting that adversely impacted the soil and created a dead zone for a couple of growing seasons. My hunch is that a big barrel of anaerobic goo was the reason why a friend's apple tree died. He dumped it out after it got so gross and stinky, and subsequently, everything around there seemed to die. He was making comfrey "tea", which was basically a big blue barrel that he kept packing with fresh comfrey leaves. It smelled like hell but he had read something on the interwebs about how great this stuff would be for his garden. It was so putrid that he decided to just kick the barrel over. Worse than just temporarilly sterilizing his soil, he created a dead space that lasted for the better part of two years.

Hi Mr Baron,
Just came across your thread. Anaerobic is not as efficient as aerobic so the process is not as quick. There are many studies that support anaerobic compost but I do not think it would not be a good thing after only a couple of months - pathogens and phytotoxins etc. Also it is worth bearing in mind that many aerobic organisms, humans included like consuming stuff that is consumed anaerobically. A good rule of thumb is the smell. If you are going to use it on your plants you want it smelling sweet.
My late Dad used to swear by anaerobic, he was always banging stuff in polythene bags and leaving it. This around 8 years ago, I admit I was incredulous but I came to it around 2016 and you know, this stuff was amazing so I am a convert.

Lawn Mower Man has been dumping and piling up grass cuttings this summer in a rather damp area and with the rain we have had this autumn as well it has all turned into a thick heavy slimy mess - presumably anaerobic composting. My fault, I quite intended to do a lot of mulching with the grass in the summer, but time slipped away. My question is what is the best thing to do with the pile - I have thought of:
- try adding it to my normal compost bins,
- add woodchip or other material to try to aerate it where it is,
- do nothing and wait to see what happens,
- or use it as a grass killing mulch where I am trying to get more perennial planting going round my orchard trees (i have a lot of leaf mould I can cover it with, plus normal compost). Other than the do nothing option, this latter seems to be the least work, but is it a sensible thing to do, and how long might it take to be safe to start planting in?
