[Stoves] Biochar in the loo

[Joshua Guinto]

Ok clay is noted.

But before that, we found a huge supply of coco peat in some of the project
areas. Coco peat, as you know is the powder that drops off from the coconut
husk as it is shredded and has a water absorbing capacity of as much as 700
%.

I would guess, coco peat, along with bio char, this will be an excellent
ingredient to the mixture.... and then of course bokashi. I have been into
bokashi and plant ferments and probiotics for quite some now and have
witnessed its effectiveness.
