In the treatment of human faeces having a starting moisture content, the faeces are pressed between opposing pressing surfaces of rollers in a dryer, to press out at least some moisture from the faeces. The pressing surfaces are moved to leave an exposed layer of pressed faeces on at least one of the pressing surfaces which is then scraped. This produces partially-treated human faeces having a moisture content of not more than 20 wt %. The partially-dried human faeces may then be combusted. This fuel is fed substantially continuously into a combustor at a rate of 0.4-15 g/min combusted continuously over a time of at least 1 hour. In the combustor, there is a reaction chamber with a drying zone and a first combustion zone. The reaction chamber is orientable to permit gravity-assisted transit of the fuel from the drying zone to the first combustion zone. The drying zone has a drying zone grate configured to hold some of the fuel while combustion of other of the fuel occurs at the first combustion zone. A toilet may incorporate such a dryer and/or combustor.

Disclosed are compositions, materials, garments, devices, and methods for controlling or neutralizing offensive odors associated with mammalian urine. For example, disclosed are personal care products (e.g., diapers), deodorizing colloidal compositions, urine-based fertilizers, portable urination systems, and methods of their use. Such deodorizing colloidal compositions, urine-based fertilizers, portable urination systems are characterized in that they contain an acrylate polymer comprising at least one acrylic acid monomer or salt thereof, which imparts a odor-neutralizing effect. Also provided are methods of recovering water from the systems disclosed herein.

A collapsible, portable toilet facility includes: a back wall; a front frame; at least two side wall frames, wherein the side wall frames are converted between a retracted position and an expanded position, wherein the depth of the side wall frames relative to the back wall is greater in the expanded position compared to the retracted position, wherein each side wall frame comprises two or more side wall members connected to each other at a pivot point, and wherein the side wall members circumvolve around the pivot point during conversion from the retracted position and the expanded position; and at least one of a urinal or a toilet.

The disclosure relates to a waste collection system designed for handling liquid and solid waste without reliance on running water. The system is also designed with modular components adapted for in-home installation, where the system can be quickly assembled and disassembled as needed, such as for moving the components to a new location based on environmental conditions. Moreover, the system is designed to facilitate easy conversions between a waste-separating toilet design and a more streamlined non-waste-separating toilet design when desired to maximize flexibility of the overall system.

The present invention relates to a smart infant toilet system and a method thereof, and the system includes a first sensor mounted to an infant product to sense external temperature and humidity, a second sensor mounted to the infant product to sense gas, third sensor mounted to the infant product to sense whether an infant rides on the infant product, a control module configured to set critical temperature and humidity, and an alarming unit configured to provide an alarm to a guardian when it is determined that the comparative temperature and humidity are out of the preset range of the critical temperature and humidity.

A toilet system includes a waterless waste disposal system. A waste liner advancement mechanism is configured to: cover a toilet seat with a liner, capture waste expelled from a user, and mechanically advance the liner into a waste storage area so as to place a fresh liner over the toilet seat after capturing the waste.
