Abstract

Method in a pneumatic waste conveying system, which conveying system comprises at least one input point (61) of waste material, a material conveying pipe (100), which can be connected to an input point (61), and a separating device or container (25), in which the material to be conveyed is separated from the conveying air, and also means for achieving a pressure difference and/or a conveying air flow in the conveying pipe (100) at least during the conveyance of material, which means comprise at least one vacuum source. In the method a vacuum source (1) is arranged in a mobile means (2), such as in a vehicle or trailer, which vacuum source is connected to a waste conveying system, and the partial vacuum/pressure difference needed for the transfer of waste material is achieved in the system, in which case waste material is transferred along the conveying piping (100, 100A, 100B, 100C, 100D, 100E, 100F) to a container (25), which is a separate container to the means (2) moving the vacuum source.
