For some cities, this task is made even more difficult due to the impossibility of installing underground containers. This is the case of Amsterdam, where in most part of the city center, garbage collection relies on citizens and tourists to drop trash bags at given collection spots, at given hours (twice a week). In this case, it is of course vital to optimize the collection process and to minimize the amount of trash bags accumulating at any of these spots.
Garbage and generic waste management is a challenging task in modern cities. Every area has its peculiar waste production pattern in terms of kind and volume of produced waste, and optimizing collection is key to reduce costs and ensure at the same time that city decor is always maintained.
