Not strictly on topic but it is biochar and there is a plant on it. It's bamboo biochar as well.

I would agree. Biochar and charcoal are fundamentally different, and it's unfortunate that the two get conflated. Biochar is produced at higher temperatures then charcoal and doesn't add to atmospheric carbon dioxide levels during production (if produced correctly). On the other hand charcoal is produced at lower temperatures and is not clean to produce so does add to atmospheric carbon dioxide levels.

this seems like a pretty good general overview: https://rosysoil.com/blogs/news/biochar-vs-charcoal
