One of the areas I was looking into was waste treatment; an area that can't be avoided. With a scenario where rain is almost continuous after a shift, the septic fields will be saturated and not of much use. Here's some compost systems that I look at:
Most of the commercial ones are aerobic and need good air circulation (need vent/fan). There are many that have internet complains that it doesn't work! that would make a real big mess! Sometimes it's because they are overloaded.
This one uses a drum that requires rotation once in a while, and the dried compost must be regularly taken out. This is one of two that is certified:

This next company is well recognized and has a lot of commercial installations. A liquid waste is produced that can be used as a fertilizer. The solid waste needs to be taken out on an infrequent basis. The tanks are tall, which means that it is not feasible to have this on the first floor.

Here's the one that I was interested in. It's based in Sweden and is the cofounder of clivusmultum. I see it as an improved design. It claims solids need only to be removed 3-5 times over 100 years. It's about 3 feet high, so can be installed for the first floor. The compost is a liquid that can be used as fertilizer like the above. It doesn't export, but I'm trying to make a licensing arrangement with the person. If any community is interested, let me know, as it may help to get a license. (He sells it in Europe).
