Vacuum waste collection system is provided (1a) by successively selecting a number of branches in a sequence for emptying and transport of waste, wherein the intersection (1, 2, 3, 4) of each next branch in the sequence is at the same o shorter transport distance to a central waste collection point (6) compared to the intersection (1, 2, 3, 4) of the previous branch in the sequence, and collectively transporting accumulated waste from the selected branches towards the central waste collection point (6) by successively operating the air inlet valves (av1, av2, av3, av4, av5) of the corresponding branches. For each selected branch except the last branch, accumulated waste is transported towards the central collection point (6) by causing the corresponding air inlet valve (av1, av2, av3, av4, av5) to be open until it is detected by detector means (WO) in the transport pipe system that the waste has been transported past an intersection (1, 2, 3, 4) to the next branch, and then changing to the next branch For the last branch, accumulated waste is transported to the central waste collection point (6).
