It is quite difficult to predict fill levels. If residents do a house clear-out and come up with a lot of waste, this can fill up such a container in one go. Nevertheless, we do try to look at the ‘behaviour’ of containers in a whole Avalex area. Because the Avalex area is so large, this is a job that can take quite some time. However, if we can improve our forecasts, we can also adjust our routes by emptying the containers more often or on a different day. That way, we try every day to ensure that the containers can be used by everyone.
