Currently, the charcoal kiln cant be used in space. Which makes sense, but now there's no way to get charcoal for astroponics in space aside from using the reactivated charcoal recipe. Maybe you could either add a way to cook it in an industrial furnace or change the recipe for reactivated charcoal to not need solid fuel so itll be viable in space without any complicated setup to get solid fuel.
But you might also want to get rid of the steam so you dont need nuclear power to get charcoal, and replace it with something so it isnt so easy to get that it becomes your source of charcoal on gleba and volcanus and fulgora. I would recommend having the recipe need oxidizer in stead of steam.
