Claim Text:
1. A method for pneumatically conveying waste material through a conveying system which comprises, in a first phase, introducing waste material from a plurality of input points to a plurality of branch conveying pipe sections; and conveying the waste material from said branch conveying pipe sections to a plurality of main conveying pipe sections; and, in a second phase, conveying the waste material from the main conveying pipe sections to a separating device or a plurality of separating devices; and providing a pump unit or a plurality of pump units which are operatively connected to the separating device or the separating devices and to the branch and main conveying pipe sections for producing a pressure differential and air current within the operating, conveying system, whereby, in the first phase, the waste material is initially transferred from the input points via the branch conveying pipe sections to the main conveying pipe sections and, in a second phase, the waste material is transferred from at least one of the main conveying pipe sections to a separating device by suction/pressure difference and/or conveying air flow produced by said pump device, and waste material transferred to other main conveying pipe sections is retained in at least one of said other main conveying pipe sections, said separating device functioning to separate the waste material from the conveying air.
