The present invention relates to a method and system of using at least one moving means for the pushing and moving solid waste from at least one holding area within buildings or outdoors through a waste transport conduit to at least one collection station or at least one collection conduit. 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.
