This is just about the only sustainable way to handle human waste.

Plant nutrients have to be kept separate from society's tech-waste. Otherwise they become hopelessly contaminated with the chemicals and heavy metals now threatning the health of humans and all other animals. Source separation and treatment on-site is the foundation for our long term composting process. A great many good consequences follow in the "low-carbon" footsteps.

Contrary to this, if we start out by delibererately mixing human excrements with drinking water for the sake of sending it off, NO type of subsequent corrective measure can undo this first action. All attempts to effectively separate the useful from the harmful has failed and the more fantastic the purification scheme, the more we contribute to global warming because of increased enthropy -- this is a law of physics that has never been contradicted.

So the conventional flush toilet is the least sustainable product we can use to deal with our human waste.
