A method for handling material and conveying air in a pneumatic conveying system for material, which conveying system comprises at least one input point (1) for material, a material conveying pipe (100), which is connectable to an input point (1), and at least two separating devices (10A, 10B), in which the material being conveyed is separated from the conveying air, and also means for bringing about a pressure difference and/or a transporting air flow in the conveying pipe (100) at least during the conveyance of material, which means comprise at least one partial-vacuum source (21). In the method, material is conveyed in a transporting air flow in a material conveying pipe from an input point in a selected manner into one of at least two separating devices (10A, 10B), and that at least one of the aforementioned separating devices (10A, 10B) is configured to function as the standby separating device of a second separating device. The object of the invention is also a separating device arrangement and a waste conveying system.
