[Stoves] Commercial application of smoke? (Re: Crispin, Ron)

[Traveller]

I remember some exchanges between Crispin and some others about tar
formation in chimneys.  I also remember Ron and Paul discussing biochar.

The story below mentions stove pipes; I suppose that is for large metal
stoves, not exhaust as such. But I wonder if there are commercial
applications of smoke.

Liquid Smoke: The History Behind a Divisive Culinary Shortcut

I think stove designs that capture the smoke within tubes should earn some
health credits and avoided black carbon GHG credits anyway. If liquid smoke
qualifies under biochar - i.e., it can be used for plant growth - then
there will be biochar credits for GHG avoidance, health benefits of soil
productivity increase. With a million dollars, any model can be tweaked.

Hello, EPA? Is liquid smoke carbon sequestration?

Can collected smoke - dry or liquid - be purified for industrial uses of
carbon? I tinkered with coke and metal products industry decades ago.

It's not the emissions but where they go how, that is the question.

To EPA or not EPA.
