Okay, in some ways bio char itself is like the regular charcoal we know from BBQs and the manufacturing process can be quite similar. But like most things, it's a very complex topic, therefore, I'll only give a very rough overview for now but I’ll also share some links to further information 👍 • While charcoal is mostly made from valuable wood, bio char can be made from every form of biomass, meaning it can be made from every form of biomass waste.
• During the manufacturing process, the chemical carbon in the biomass is put into a form that is stable for several thousand years, so unless the bio char is burned again it can’t reenter the atmosphere. • Each ton of bio char produced using plant based waste is equivalent to 2.6 tons of atmospheric carbon dioxide captured by those plants. • The manufacturing process generates a small amount of base-load energy which can be, depending on the size of the facility, enough for several hundreds of households. • The end product can be used to revitalize the extremely degraded soils we're fighting in industrial agriculture right now.

Tl:dr we (indirectly) take something very bad from the atmosphere, generate useful energy with it and then store it within our dead soils to revitalize it.

It is not THE solution but I think it’s a feasible improvement.

I’m happy to answer more questions... here are some links ✌️
