ABSTRACT:
This invention is a sanitary disposal system for human waste and organic garbage by aerobic composting combined with solar evaporative distillation for greywater. The aerobic composting reduces waste volume by ninety percent leaving water, carbon dioxide and a harmless but fertile ash by-product. Except for urine, the system essentially operates dry. No chemicals, septic system, or sewage treatment plant is required. There is no odor and no polluting discharged during operation. A nonsoiling toilet seat is provided so a dry toilet bowl may be used without the usual problems of cleaning. Insects are prevented from entering or leaving the system which is constantly aerated to assure that the composting process does not convert to anaerobic. The greywater system further enhances pollution control. This includes solar evaporative distillation to separate out solids which can be disposed of in a sanitary dump while the reclaimed water can be used for non-household purposes.
