What kinds of chemical products can be made from the ash left after cooking in rural areas?

Are many people on our side purchasing this? I hope an expert can give some advice.
Is it definitely for chemical products? There might be other uses as well. By the way, what do you use for heating over there? Bamboo or Platycodon?
It should be potassium carbonate, which is present in plant ash!
Plant ash contains potassium carbonate, but the concentration is likely not very high; potassium carbonate can be extracted using plant ash as a raw material.
We usually just pour it directly into the soil, and that way we save a lot on fertilizer costs in the following year, hehe.
It might also be used for fertilization, to recover potassium carbonate from plant ash – it sounds like a quite ancient technique.
Most of it is collected to be used as fertilizer; it can be applied directly to the soil as such, or it can be processed into compound fertilizers.
Is it being recycled to make organic fertilizer? Nowadays, many places advocate green agriculture; chemical fertilizers cannot be used, only organic fertilizers are permitted. It’s great to recycle materials to use them as organic fertilizers
It’s probably been used as fertilizer for plants
It turns out to be the source of potassium fertilizer; indeed, potassium carbonate is present there. I heard this from my chemistry teacher in high school – back then, people would soak plant ash and use the resulting water to wash their hair; it functioned like shampoo. But for industrial recycling, it’s unlikely, as the quantity is small and the concentration is low. There must be other uses for it.
Is it being used as organic fertilizer? Where I am, we use plant ash to fertilize crops.
It should be used for extracting potassium salts, as the ash contains potassium carbonate.
