A vacuum waste collection system is provided by successively selecting a number of branches in a sequence for emptying and transport of waste, wherein the intersection of each next branch in the sequence is at the same or shorter transport distance to a central waste collection point compared to the intersection of the previous branch in the sequence, and collectively transporting accumulated waste from the selected branches towards the central waste collection point by successively operating air inlet valves of the corresponding branches. For each selected branch except the last branch, accumulated waste is transported towards the central collection point by causing the corresponding air inlet valve to be open until it is detected that the waste has been transported past an intersection to the next branch, and then changing to the next branch. For the last branch, accumulated waste is transported to the central collection point. |
