So this mod only works till you start using electric furnaces and get off of steam power then? Because from all the images it looks like this only works with boilers, burning inserters and basic and blast furnaces. I also believe that in space age on fulgora and vulcanus you are far enough into the game to not use any of those and it doesn't sound like anything makes ash there, gleba and aquilo on the other hand still require burning a lot so that would leave those two in the late game...

But do modded planets such as cerys actually work with this mod? Cause cerys adds heating towers and I'm curious whether or not those work with this.
Also I do know about the air filter mod which seems to add back the ash thing into center focus
