Claim:
1. A method for conveying waste material from input points to a waste station, in a pneumatic waste conveying system, which comprises, providing an extensive waste conveying system formed from a plurality of subsystems, operatively connected to a waste station; providing, in a first phase, at least one input point for supplying waste material toe conveying pipes of said subsystems, conveying said waste material through the conveying pipes by a pressure difference produced in the conveying pipes to an accumulator tank which functions as a separation device of each of the subsystems where the waste material is separated from the conveying air; and providing a second phase wherein the accumulator tank of the subsystem is emptied by selectively conveying the waste material from the accumulation tank of each of the subsystems to the waste station; wherein the airflow for conveying the waste material is generated by a partial vacuum generating system as a means for achieving a pressure difference and which is provided in the waste station and is adapted to communicate with the accumulator tanks of each of the subsystems and with the entirety of the conveying pipes of said subsystems for achieving the pressure difference in the waste conveying system.
