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). |

1. A method of operating a vacuum waste collection system having a transport pipe system for transport of waste to a central waste collection point, the transport pipe system including one or more transport pipes having a number of branches and associated intersections, each branch having an air inlet valve at an end of the branch, the method comprising:
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 the central waste collection point compared to the intersection of a previous branch in the sequence; and collectively transporting accumulated waste from the selected branches towards the central waste collection point by successively operating the air inlet valves of the corresponding branches; wherein collectively transporting accumulated waste involves
transporting, for each selected branch except a last branch in the sequence, accumulated waste towards the central collection point by opening the corresponding air inlet valve until detector means in the transport pipe system detects that the waste has been transported past an intersection to the next branch, and then changing to the next branch, andtransporting, for the last branch, accumulated waste to the central waste collection point. |
