Abstract: A transport chute includes an upper slide defining an opening, a lower slide coupled to the upper slide, a pivoting plate pivotably coupled to the upper slide, and a resilient member coupled between the pivoting plate and the lower slide. The pivoting plate is configured to open and close the opening. The resilient member is configured to drive the pivoting plate to close the opening after the opening is opened. A workpiece is transported from the upper slide to the lower slide through the opening.

Abstract: A system for transporting and collecting bio-waste without the use of water as a carrier of the bio-waste is disclosed. The system comprises a plurality of bio-waste carts configured to receive and transport bio-waste along a plurality of predefined pathways to a central chute. The system further comprises a bio-waste depository associated with the central chute. The system further comprises a transport system comprising a plurality of locomotive devices configured to advance and return the plurality of bio-waste carts along predefined pathways and through tunnel-like structures to and from the central chute.

Abstract: A waterless toilet includes a urine/feces separation device, a transport conveyor, and a drier drum inside a casing. The urine/feces separation device includes rotary plates and fixed plates. The rotary plates are substantially triangular. Each fixed plate is provided between a pair of adjacent rotary plates. The transport conveyor has an endless belt wound around a driver roller and a driven roller. The drier drum includes drum main bodies and a drum heater. The drum main bodies are constructed like a metal net and supported in such a manner as to be freely rotatable. A first receptacle is provided below the urine/feces separation device to collect urine. The collected urine is heated and vaporized by a heater. Dried, solid waste is collected in a second receptacle below the drier drum and further dried by the heater.

Abstract: A system for receiving and transporting bio-waste without the use of water as a carrier of the bio-waste is disclosed. The system comprises a bio-waste receptacle configured to receive bio-waste and is associated with an exterior wall of a structure. The system further comprises a bio-waste cart receivable at least partially within the bio-waste receptacle and comprising a base and a collection bucket for receiving the bio-waste, the base having a plurality of wheels for transporting the collection bucket. The system further comprises a transport system for moving the bio-waste cart along a pre-defined pathway, the transport system comprising a tunnel-like structure and a mechanical, manually operated locomotive device and wherein the tunnel-like structure conceals the pre-defined pathway and at least a portion of the mechanical, manually operated locomotive device. The system further comprises a bio-waste depository positioned on the pre-defined pathway for receiving the transported bio-waste.
