The present invention, relates to a modular toilet system designed to provide a sustainable, waterless, and eco-friendly sanitation solution The system employs a two-tier chamber arrangement utilizing a specially formulated bacterial culture to treat human waste, transforming it into an odorless, pathogen-free, nutrient-rich liquid organic fertilizer suitable for agricultural applications. The modular toilet system comprising: a toilet bowl seat configured to receive human waste, including urine and faeces; a two-tier chamber arrangement comprising an upper first chamber and a lower second chamber, wherein the upper first chamber is disposed beneath the toilet bowl seat and configured to collect and treat human waste using a specially formulated bacterial culture, and the lower second chamber is configured to collect and store liquid organic fertilizer.

A composition may include, in dry form: (a) nigrosin; (b) wheat flour; and (c) whole egg. Such compositions may be used for production of test soil for assessment of the cleaning action of cleaning devices. Methods of producing a test soil for assessment of the cleaning action of cleaning devices for cleaning of vessels for human egesta, e.g., of washer-disinfectors, including dissolving the composition in an aqueous medium. A test soil may include the constituents of the composition in an aqueous medium, and such soils may be used for assessment of the cleaning action of cleaning devices. A method may assess the cleaning action of cleaning devices for cleaning of vessels for human egesta.

A hydraulic propulsion system for disposing of human waste. The system includes a toilet having a bowl, and a base below the bowl. The base is secured to the chassis of a vehicle, or to a remote sanitation facility. The system also comprises a hydraulic flushing mechanism associated with the toilet, and a fluid receiving chamber that receives water and human waste when the flushing mechanism is actuated. The human waste is directed through a sewage ejection pipe and into a black-water tank or a municipal sewer system. The human waste propulsion system further comprises a pneumatic line. The pneumatic line is in fluid communication with the fluid receiving chamber proximate the bowl. The pneumatic line receives compressed air which is delivered when the hydraulic flushing mechanism is actuated. Additionally, the human waste propulsion system has a controller.

Waste collection and processing systems for use in low-gravity environments include a toilet having a bowl and a lid; a first waste tank having an inlet and an outlet, with the bowl of the toilet selectively fluidly coupled to the inlet of the first waste tank; a second waste tank having an inlet and an outlet, with the bowl of the toilet is selectively fluidly coupled to the inlet of the second waste tank; a controller configured to selectively operate each of the first waste tank and the second waste tank between reclamation modes of operation and collection modes of operation. When the first waste tank is operated in the reclamation mode of operation the second waste tank is operated in the collection mode of operation and vice versa.
