You could do this. A tonne of food waste would optimally give you around 120m3 of biogas at this sort of scale. In energy terms, that’s about 3100 MJ. In kg wood equivalent, that’s about 120kg, give or take.
The average family produces around 150kg of food waste a year. Or about 18kg, wood equivalent. You could add other materials to this, but the yields will vary depending on feedstock. AD makes sense when you have a reasonable input. Volume is a consideration.

Looked into this a while back dear, I’ve got the location and the system in mind for it.
Reply Covered, fenced concrete slab between the candle and the shed tank. Livestock are butchered and shorn there, all wastes to go into the digester as well as a shed toilet’s wastes.

Nice! But how do you actually use the methane from the ballons? Don’t it need to be pressurized?

Really keen to try this. I have the tank. Have the natural gas powered oven. Like the hook up to shower grey water for heat idea and sink grinder. The only downside is my chickens will miss out on my vege scraps.
