Nowadays, Urban Waste Collection process has become cru- cial to ensure cities’ wealth and viability. The growth of urban centers and the rapid expansion of industry led to a revision of plans and waste collection routes to increase their efficiency and effectiveness. Traditional approaches for the Vehicle Routing Problem and the Waste Collection Problem are not taking into account some factors such as the huge amount of available information produced by the Internet of Things de- vices. In this paper we propose a solution allowing an Internet of Things mid- dleware to conform with reactive programming paradigm that hence will be more flexibile and adaptive for the Waste Management Problem by retrieving the best route planning using all real-time information avail- able in a Smart City context. All gathered data stoke a predictive model used to estimate the best timing to optimize the waste collection, allow- ing the system to plan optimal routes accordingly to the state of bins across the city area. Keywords: Reflective middleware, Internet of Things, Waste Manage- ment Problem, Deep Learning 1 Introduction and motivation The Smart City paradigm has become one of the most important research top- ics around the globe. Many cities across the world promote Smart City models, which include a wide range of features for sustenance to provide municipalities with a better use of their resources using Internet of Things (IoT) sensor network to monitoring all city data, from environmental to bus tracking. In this model all data becomes useful information for day-by-day decision making. This processes driving all cities living and becoming fixed references for example for linking and upgrading infrastructures, technologies and services in transportation, en- ergy grid and so on. Waste management organization and city administrations, in different location provide the challenge to an efficient and effective system to collect, dispose-off, and recycle the waste, with particular attention for the health
