Waterless Urinal

Abstract

A system for disposing of bodily waste includes at least one receptacle that includes a receptacle drain outlet. The at least one receptacle is configured to receive and direct a first waste to the receptacle drain outlet. A passageway includes a first passageway inlet that is coupled to the receptacle drain outlet. The first passageway is configured to receive and direct the first waste to an external area. A flushing system includes a source of a second waste and includes an activation device that introduces the second waste into the passageway in response to a signal. The second waste flushes a buildup associated with the first waste from the passageway.

What is claimed is: 
     
         1 . A system for disposing of bodily waste, comprising:
 at least one receptacle including a receptacle drain outlet, the at least one receptacle being configured to receive and direct a first waste to the receptacle drain outlet;   a passageway including a first passageway inlet and a second passageway inlet, the first passageway inlet being coupled to the receptacle drain outlet, and the first passageway being configured to receive and direct the first waste to an external area; and   a flushing system connecting the second passageway inlet to a source of a second waste, the flushing system including an activation device introducing the second waste into the passageway via the second passageway inlet in response to a signal, the second waste flushing from the passageway a buildup associated with the first waste.   
     
     
         2 . The system according to  claim 1 , wherein the at least one receptacle includes a urinal and the first waste includes urine. 
     
     
         3 . The system according to  claim 1 , wherein the second waste includes gray water. 
     
     
         4 . The system according to  claim 3 , wherein the source of the second waste includes at least one of a laundry machine, a dish washing machine, and a sink. 
     
     
         5 . The system according to  claim 1 , wherein the flushing system further includes a treatment system for treating the second waste before introducing it into the passageway. 
     
     
         6 . The system according to  claim 1 , wherein the flushing system further includes a recycling system for receiving and recycling the second waste received into the passageway, the recycled second waste being reintroduced into the passageway by the flushing system. 
     
     
         7 . The system according to  claim 1 , further comprising a signal source for generating the signal, wherein the signal source includes at least one of a proximity sensor detecting a presence of a user of the at least one receptacle, a heat rate change sensor detecting the first waste received into the passageway, a buildup sensor detecting the buildup associated with the first waste, a timer, and a light switch operated in an area of the at least one receptacle. 
     
     
         8 . The system according to  claim 1 , wherein the flushing system includes a storage chamber for collecting and storing the second waste from the source before the second waste is introduced into the passageway. 
     
     
         9 . The system according to  claim 1 , wherein the at least one receptacle is associated with a manually operated flush valve operated by a user of the receptacle to flush the at least one receptacle and the passageway. 
     
     
         10 . The system according to  claim 1 , wherein the at least one receptacle is at least partially covered with a coating that minimizes odor and discoloration of and adhesion to a surface of the receptacle. 
     
     
         11 . A system for disposing of bodily waste, comprising:
 at least one receptacle including a receptacle drain outlet and a receptacle inlet, the at least one receptacle being configured to receive and direct a first waste to the receptacle drain outlet;   a passageway including a first passageway inlet, the first passageway inlet being coupled to the receptacle drain outlet, and the first passageway being configured to receive and direct the first waste to an external area; and   a flushing system including a source of a second waste, the flushing system including an activation device introducing the second waste into the first passageway in response to a signal, the second waste flushing from the passageway a buildup associated with the first waste.   
     
     
         12 . The system according to  claim 11 , wherein the at least one receptacle includes a urinal and the first waste includes urine. 
     
     
         13 . The system according to  claim 11 , wherein the second waste includes gray water. 
     
     
         14 . The system according to  claim 11 , wherein the flushing system delivers the second waste to the passageway via the receptacle drain outlet. 
     
     
         15 . The system according to  claim 11 , wherein the flushing system further includes a treatment system for treating the second waste before introducing it into the receptacle. 
     
     
         16 . The system according to  claim 11 , wherein the flushing system further includes a recycling system for receiving and recycling the second waste received into the receptacle, the recycled second waste being reintroduced into the receptacle by the flushing system. 
     
     
         17 . The system according to  claim 11 , further comprising a signal source for generating the signal, wherein the signal source includes at least one of a proximity sensor detecting a presence of a user of the at least one receptacle, a heat rate change sensor detecting the first waste received into the passageway, a buildup sensor detecting the buildup associated with the first waste, a timer, and a light switch operated in an area of the at least one receptacle. 
     
     
         18 . The system according to  claim 11 , wherein the flushing system includes a storage chamber for collecting and storing the second waste from the source before the second waste is introduced into the first passageway. 
     
     
         19 . The system according to  claim 11 , wherein the at least one receptacle is associated with a manually operated flush valve operated by a user of the receptacle to flush the at least one receptacle and the passageway. 
     
     
         20 . The system according to  claim 11 , wherein the at least one receptacle is at least partially covered with a coating that minimizes odor and discoloration of and adhesion to a surface of the receptacle.
