What is a "stove"? Why can't it be a char-maker? Or why can't a
"char-maker" also provide pyrolytic gases for cooking, process heating?

If I understand Paul and Ron correctly, what they are talking about is
"cook-char" -- charcoal produced during cooking, and available for later
use, or sale for soil conditioning or fuel.

I don't know if the chars so produced can be burned in any old portable
charcoal stoves, but otherwise there is a question of finding and marketing
charcoal stoves that can use that char. (Not a consideration for soil
conditioning if the char is granular or can be used as is.)

But let me turn the "cook char" around -- how about cooking as a byproduct
of char production?

Why is everybody so hung up on "households"? From cursory observations,
driving around and looking at billboards or television, it seems to me the
"food services industry" is expanding at a faster pace than household

Has nobody been paying attention?

Commercial-scale char-making (and briquetting) is a natural candidate for
co-production of prepared foods. Conversely, every restaurant or canning
factory can use pyrolytic gases for cooking and sell char.

Leave WHO and UN SDG types to count statistics of  households. More than a
half of the time is spent outside the home and more than a half of the
meals preparation (including partial preparation for home cooking) is done
outside the home.

Think moolahs, not satisfying the fatwas of mullahs.
