Ha, I dont know about that. Someone bought it, just a bucket and a toilet lid and since I was into biochar, I thought I could make this a little less disgusting.
I even trialled a bird cage with char as a substrate, worm farming, greywater reed bed, tank base, water treatment -drinking and dirty, potting medium, animal pen flooring, animal feed etc. I used to share all the experiments. Char is easy to make at home and it does have a 1001 uses while having the feel good of permanently locked carbon. One thing I haven't done as I dont have one is use it as the replacement for "carbon" in a proper composting toilet system, I think it would be much better than sawdust.
I probably wouldn't use it as a kitty litter tray as the dirty footprints after would be a bit disgusting but it would work.
If it’s “permanently locked carbon” then that would imply it’s not available for chemical reactions. And so I don’t see how it can be the browns in your compost. Doesn’t it have to be bioavailable to be composted? If it’s available for reactions, it isn’t permanently sequestered, right?
