  • Publication number: 20080307574
    Abstract: A portable composting toilet system has a compartmentalized receptacle for receiving human waste, a gray-water circulation subsystem for circulating gray water formed by mixing water with waste through the compartmentalized receptacle to promote mixing of the waste to thereby accelerate digestion of the waste, and an air-circulation subsystem for emitting air bubbles into a sludge formed at a bottom of the compartmentalized receptacle to break up the sludge to thereby accelerate digestion of the waste. The air circulation subsystem can include an air-driven pump that causes the gray water to circulate while allowing feeding pressurized air to diffuser loops in each compartment to create sludge-breaking bubbles. This portable composting toilet system so efficiently decomposes waste that the maintenance costs of hauling residual sludge to the surface (when the toilet is used underground in a mine) is significantly lower than for conventional toilets, thus providing substantial cost savings to mine operators.

  • Patent number: 6668392
    Abstract: An enclosure for a portable toilet comprises at least two sections, one of which has a door opening and a door mounted thereon. The enclosure door is moveable between a closed position and an opened position. Each enclosure section includes a first end and a second end. A tab having a hole extends from the first and a hole is formed in the second end of each enclosure section. When assembled, the first end of one section abuts the second end of the adjacent section. To ensure a substantially smooth seam or junction between the two sections, the tab extends from the inner surface of one section, across the junction between the two sections, to lie against the inner surface of the adjacent section. The tabs are aligned with the holes, and are sized such that the tab holes align with the section holes. A fastener is passed through the section hole and the tab hole to secure the two sections together. Mounting tabs are also provided at the bottom of the enclosure to secure the enclosure to the base.
