mmm, good point. i think i'd put the bins just outside the dome, probably on the opposite side from where you sleep (because compost attracts rats, bugs, etc), and run the tubing under the wall & into a grow bed that runs alongside that wall. you can't disturb humanure compost, just gotta let it rot, and it needs both high heat (which it generates by itself if you balance it) and time - we let ours cure for a year after we close a bin. we have a three-bin system made of pallets. we bust up a strawbale into the base of one, then put humanure buckets & any kitchen scraps that aren't going to the animals in. our animal manure compost is separate, because it's too high-volume to do together, and we mostly have poultry, and poultry manure rots safer/faster than human. over every bucket of manure, we add the same volume of leaves/dry straw/grass clippings/sawdust/other carboniferous material (always cottonwood leaves for us, because we live under 9 large cottonwoods and have an endless supply, but whatever's local to you will work; sawdust is very odor-absorbent, which is nice). once the bin is full, we throw a pallet over it to mark it closed, and move to the next bin while the first one rots. when it's been a year (i make a calendar note also), then we open it and rake out the black gold. anything uncomposted goes in the bottom of an empty bin for later. primary culprits: "compostable" silverware, which requires very high heat, coconut shells, sometimes chicken bones. it eats everything else. whole dead hens who die of age, meat, cheese, citrus, whatever. everything people say "that can't go in compost," our compost eats. :) (what they mean is "that will attract rats in your compost." i think the clarification matters, because in a suburban setting, not attracting rats is important. in my setting, it just determines where i put the bins.)
