We are talking about Mars, but Earth-based biomethane production is how large farms get rid of their waste legally. Like this large biogas methane electric plant in Europe (pic).

Here's an example of a very large biomethane plant and how it works.

These are of course scalable as you can see in the images in >>8431226 and >>8430579

>No one is disputing the viability of anaerobic digestors.

Someone is. lol

>But you're underestimating the the sheer magnitude of waste required for an acceptable volume of methane output.

Not at all. However, humans create a lot of waste. The methane is just one bonus for making better fertilizer. The entire process helps itself in maintaining its heat level. It is also a 100% good bet because the method is easy, the fuel resource already acquired, and the biomass is always being produced. All the mining and drilling methods rely far too much on the hope that it will be viable in the time frame it is needed. You could have biogas methane and high-nitrogen fertilizer being made aboard the first ship before even arriving, just for the starter culture, since it can take 3-6 months to get the process started without a good culture to start with.
