The movement of the at least one moving means is driven by generating differential pressure across the at least one moving means to push and move the solid waste towards the at least one collection station or at least one collection conduit. The differential pressure creates systematic directional air movement inside the waste transport conduit to move the at least one moving means to move and push the solid waste to the at least one collection station or at least one collection conduit. The differential pressure is delivered by controlling a system of valves that is connected to at least one higher pressure air conduit and at least one lower pressure air conduit or removes air to or from the waste transport conduit respectively. Both the at least one higher pressure air conduit and at least one lower pressure air conduit is connected to air handling apparatus. ## Claims ### Claim 1 A system for conveying solid waste from at least one holding area into at least one collection location, the system comprising: at least one holding area configured to hold solid waste; a means for regulating discharge connected each holding area, the means for regulating discharge being configured to regulate the solid waste discharged from the holding area connected thereto; a waste transport conduit fluidly coupled with each holding area through one of the means for regulating discharge; at least one collection location fluidly coupled to the waste transport conduit, said collection location being selected from a collection station or collection conduit; and at least one moving means slidably located inside the waste transport conduit, each moving means being configured to move the solid waste from the means for regulating discharge to the at least one collection location, wherein the waste transport conduit has at least one conveying zone between the at least one holding area and the at least one collection location, each conveying zone having at least one zone valve, each conveying zone having a first pressure conduit at a first zone end and a second pressure conduit at a second zone end, the first pressure conduit and second pressure conduit being fluidly coupled to a differential pressure system that provides a pressure differential between the first pressure conduit and second pressure conduit when the at least one moving means is located in the conveying zone between the first pressure conduit and second pressure conduit. ### Claim 2 (depends on 1) The system of claim 1, wherein the differential pressure system includes: at least one higher pressure air conduit; at least one lower pressure air conduit, wherein the at least one lower pressure air conduit includes air at a lower pressure than higher pressure air in the at least one higher pressure air conduit; at least one first higher pressure air conduit valve between the at least one higher pressure air conduit and the first zone end; at least one second higher pressure air conduit valve between the at least one higher pressure air conduit and the second zone end; at least one first lower pressure air conduit valve between the at least one lower pressure air conduit and the first zone end; and at least one second lower pressure air conduit valve between the at least one lower pressure air conduit and the second zone end. ### Claim 3 (depends on 1) The system of claim 1, comprising a plurality of the holding areas; and a plurality of means for regulating discharge. ### Claim 4 (depends on 1) The system of claim 1, wherein the at least one collection conduit is linked to a docking station that is connectable to a vehicle mounted container by a vehicle mounted transport conduit. ### Claim 5 (depends on 1) The system of claim 1, wherein the waste transport conduit has a conduit diameter sized from 0.075 m to 1.0 m. ### Claim 6 (depends on 1) The system of claim 1, wherein the waste transport conduit includes at least one primary conveying zone. ### Claim 7 (depends on 6) The system of claim 6, wherein the at least one primary conveying zone is linked to a docking station that is connectable to a vehicle mounted container by a vehicle mounted transport conduit. ### Claim 8 (depends on 6) The system of claim 6, wherein the waste transport conduit and at least one primary conveying zone comprise a range of conduit diameter sized from 0.075 m to 1.0 m. ### Claim 9 (depends on 1) The system of claim 1, further comprising a control and monitoring system operably coupled with the differential pressure system so as to control movement of the at least one moving means. ### Claim 10 (depends on 1) The system of claim 1, wherein the at least one moving means includes a moving member with a position tracking device to identify position of the at least one moving means and to control direction of movement of the at least one moving means in the waste transport conduit. ### Claim 11 (depends on 9) The system of claim 9, comprising a plurality of sensors operably coupled with the control and monitoring system. ### Claim 12 (depends on 11) The system of claim 11, wherein the at least one moving means includes a moving member with a position tracking device to identify position of the at least one moving means and to control direction of movement of the at least one moving means in the waste transport conduit, wherein the plurality of sensors monitor the position tracking device. ### Claim 13 (depends on 12) The system of claim 12, wherein the position tracking device is a radio frequency tag. ### Claim 14 (depends on 12) The system of claim 12, wherein the position tracking device is a magnet. ### Claim 15 (depends on 1) The system of claim 1, wherein the means for regulating discharge includes a valve. ### Claim 16 (depends on 1) The system of claim 1, comprising: a plurality of conveying zones; and a plurality of zone valves, wherein at least one conveying zone has a zone valve at each end, wherein the first pressure conduit and second pressure conduit are between the zone valves at each end of the conveying zone. ### Claim 17 (depends on 1) The system of claim 1, wherein the at least one moving means is a shuttle configured to push the solid waste through the waste transport conduit.
