permaculture

[Marimike6@cs.com]

 Any system that liquefies manures, particularly offensive ones from 
omnivores like people or pigs, needs to include an aerobic stage.

Anaerobic systems are great for harvesting biogas, but are quite offensive 
and leave a residue that requires further treament. A good way to render this 
residue sweet and useful for soil amendments-- even if you don't first 
harvest 
the gas-- is to hook up a pump that sucks from the bottom of your tank and 
sprays it onto the top. This way the anaerobic bottom layer gets mixed with 
air 
and circulates the entire volume of the tank. In time, magic occurs and you 
have 
no longer shit, but shinola.
