Abstract. Residential garbage collection is an important urban issue to address in modern cities, being a key activity that explains a large proportion of budget expenses for local governments. Under the smart cities paradigm, specific solutions can be developed to plan a better garbage collection system, improving the quality of service provided to citizens and reducing costs. This article addresses the problem of selecting locations for community bins in a medium size Argentinian city, that stills uses a door-to-door system. An integer programming model is presented to locate community bins that minimize the installment cost while also maximize the days between two consecutive visit of the collection vehicle. Results demonstrate that the proposed model and the proposed resolution algorithm were able to provide a set of suitable solutions that can be used as a starting point for migrating from the current door-to-door system to a community bins system.

Introduction
Urbanization has increased the pressure over governments to find intelligent and efficient solutions to provide high quality services to citizens. In this sense, Information and Communication Technologies (ICT) is a valid tool for the authorities to enhance the living conditions under the new paradigm of smart cities. Therefore, several urban services have been improved with the aid of ICTs. Recent examples have been reported for public transportation [22,27], health services [33] and energy management [26], but also in other non-traditional fields, such as education [16]. ICTs have also been effectively applied to mitigate the environmental and economic problems in Municipal Solid Waste (MSW) management [19,25,34]. c Springer Nature Switzerland AG 2019 S.

Facility Location of Solid Waste Community Bins in Smart Cities

This article studies the problem of selecting the proper location of garbage community bins for a city with the aim of migrating from a door-to-door collection to a community bins system that is expected to be more efficient in terms of logistic costs [2]. Particularly, a case of study of the city of Bah´ıa Blanca, which is an important medium size city in the South of Argentina, is addressed in this work. The objective of migrating from the current door-to-door collection system to a community bin based one, where the citizens have to carry their waste to certain bins, is usually among the plans of the local authorities for reducing the collection complexity. Solutions that contribute to reduce logistics cost are of particular interest for Argentinian cities since they are extremely high in this
