A portable waste collection device which includes a support frame configured for a user wherein a bag slideably engages to the frame to hold the open end of the bag to collect waste that can be easily sealed for disposal.

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.

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.

Systems and apparatuses for allowing passive urine recovery are disclosed. An exemplary commode liner that allows for passive urine recovery comprises a first layer comprising a first top side configured to receive a bio-waste material, a first bottom side, and a plurality of apertures spanning the first top side and the first bottom side, wherein the plurality of apertures passively promote a unidirectional movement of a liquid portion of the bio-waste material from the first top side to the first bottom side. The liner further comprises a second layer attached to the first layer, wherein the second layer is attached to the first layer such that a space is created between a second top side of the second layer and the first bottom side of the first layer, wherein the space is configured to hold a liquid portion of the bio-waste material received at the first top side.

A toilet apparatus has a waste material receiving bowl with an opening to receive an absorbent media and indicator and a sensor to detect a presence of the indicator in the material receiving bowl when the indicator is present in the material receiving bowl and transmit a signal indicating the indicator is present in the material receiving bowl. A control circuit receives the signal from the sensor, processes the signal to determine the indicator is present in the material receiving bowl, and causes one or more actions to be taken by the toilet apparatus based on determining the indicator is present in the material receiving bowl.

A portable toilet including: a bowl made of soft material; and a resilient loop integrated with the bowl, the resilient loop forming a rim of the bowl; wherein the bowl comprises a chamber at the bottom of the bowl. The chamber holds a bag which is taken out to cover the bowl during use.

The present invention is a toilet assembly having a central main bowl, waste bag, bag entrance guide, bag openers with clips, a roller assembly operatively associated with each of the waste bag and the bag openers, the roller assembly constructed and arranged to close and seal the waste bag.

An environmentally-friendly, portable waterless toilet for mobile environments that is provides a single-action pedal mechanism to close the lid, advance a continuous bag with waste, and seal the waste in the bag. The toilet uses a continuous bag supply having a predetermined single dose or portion of at least one chemical automatically deposited therein, the at least one chemical functional to kill pathogens in waste that is deposited through an opening in the seat and a corresponding opening of the continuous bag supply. The waste-filled continuous bag supply is at least temporarily sealed by activation of a mechanical sealing mechanism, and released downwardly into a base section, which is connected to a sitting unit, forming an integral, closed system for waterless sanitation.

A toilet apparatus has a waste material receiving bowl with an opening to receive an absorbent media and indicator and a sensor to detect a presence of the indicator in the material receiving bowl when the indicator is present in the material receiving bowl and transmit a signal indicating the indicator is present in the material receiving bowl. A control circuit receives the signal from the sensor, processes the signal to determine the indicator is present in the material receiving bowl, and causes one or more actions to be taken by the toilet apparatus based on determining the indicator is present in the material receiving bowl.

The invention relates to a method for converting secondary biological material into reusable energy and for storing said material, said method initially packages, transports, and stores the secondary biological material in portions in at least one gas-tight encasing material in at least one layer. The encasing material and/or a material added to the secondary biological material hereby promotes production of at least one gas in the casing. Further, the invention relates to an encasing method for sealing secondary biological material in portions in casings comprising at least one transport device which is designed to form an accommodation depression together with the first encasing material. The invention further relates to an encasing device for sealing secondary biological material in portions in a sealed casing for each portion comprising at least one fill opening for accommodating a portion of the secondary biological material to be sealed on an encasing material in at least one accommodation body. An encasing material according to the invention comprises a flat, single web or multiple flat webs in multiple layers or a tube, comprising at least one gas-impermeable layer.
