Abstract: A method for processing sewage eliminates chemical "treatment", or, the addition of chemicals that are as harmful or more so to the environment as raw sewage. The method of processing sewage disintegrates the generally solid components of sewage into a highly de-moisturized powder via alternative processes of either (i) a freeze-drying process, or (ii) a combination centrifugal separation and an evacuated "bake-out" process, both which substantially drive out the vaporizable components of the sewage. In consequence, there are no resultant effluent and/or exhausting vapors from this method which would impact the environment.
