Interesting. I do something similar, but we make this biomass, or compost, from plant residues from the field. But there must be plenty of moisture; otherwise, it will take a long time. After about three years, we can use this compost again in the field. But if we put in some food scraps, like rotten tomatoes, pumpkins, and so on, then all sorts of animals come and eat it, from mice to snails, and then in the spring, when we sow the field with crops again, they eat the crops... so you have to be careful with that...

But, as you said, that's a video niche :)
