  • Patent number: 6585899
    Abstract: Disclosed are waste processing systems capable of being used on-board a transport such as a train, bus, airplane, boat, or other similar vehicles. The liquid waste is evaporated and condensed primarily as water vapor. The resulting liquid may be safely discharged in most places without adverse environmental and health effects. If desired, the liquid can be stored and reused for non-potable applications such as toilet flushing. The solid waste is converted to inert ash or carbon and may be either stored in a filter or discharged as carbon or ash into the water, air, or onto the railroad tracks. The system may also be used in stationary or semi-stationary applications where on-site treatment of waste may be desired.

  • Patent number: 6139744
    Abstract: A waste treatment device for treating waste having both liquids and solids therein includes a primary waste reservoir which receives influent waste and includes biological decomposing enhancing media for enhancingly biodegrading the waste rendering a first phase separation of solids and liquids and a secondary waste reservoir operably connected to the primary waste reservoir to receive substantially liquid waste having suspended solids therein and includes biological decomposing enhancing media for biodegrading the received waste rendering a second phase separation of solids and liquids.

  • Patent number: 6048452
    Abstract: A waste treatment device for treating waste having both liquids and solids therein includes a primary waste reservoir, a solids processor operably connected to the primary waste reservoir to receive waste therefrom in a manner to permit combustion of a substantial part the solids and generate a resultant waste, ash and gas, a secondary waste reservoir operably connected to the solids processor to receive the resultant waste, and a liquid processor operably connected to the secondary waste reservoir to receive the resultant waste in a manner to separate at least a part of the resultant waste into an environmentally safe water and resultant waste concentrate.
