With a permanent place we can finally make use of our never ending resources. We set up systems to turn human waste into bio gas, fertiliser and compost.

Love this! Let's Terra Preta the shit out of our shit! :) https://en.wikipedia.org/wiki/Terra_preta
Just a small input, (an information I received from a friend of mine, not researched by myself yet, so don't trust it,) which might be problematic: Using human waste as a food fertiliser is apparently rather problematic, because it can lead to a variety of diseases, that don't occure with animal-based or artificial fertilizer. Maybe we might need to look for a bio(-friendly), zero-emission alternative...
My understanding is that it depends on how quickly one wants to grow (food) crops in soil with humanure added. And how it's been treated of course!
Given enough time anything is safe (including nuclear waste but let's not wait that long). :)
