Abstract
Global industry is undergoing major transformations with the genesis of a new paradigm known as the Internet of Things (IoT) with its underlying technologies. Many company leaders are investing more effort and money in transforming their services to capitalize on the benefits provided by the IoT. Thereby, the decision makers in public waste management do not want to be outdone, and it is challenging to provide an efficient and real-time waste management system. This paper proposes a solution (hardware, software, and communications) that aims to optimize waste management and include a citizen in the process. The system follows an IoT-based approach where the discarded waste from the smart bin is continuously monitored by sensors that inform the filling level of each compartment, in real-time. These data are stored and processed in an IoT middleware providing information for collection with optimized routes and generating important statistical data for monitoring the waste collection accurately in terms of resource management and the provided services for the community. Citizens can easily access information about the public waste bins through the Web or a mobile application. The creation of the real prototype of the smart container, the development of the waste management application and a real-scale experiment use case for evaluation, demonstration, and validation show that the proposed system can efficiently change the way people deal with their garbage and optimize economic and material resources.
Highlights
The proposed system includes sensor technologies where waste information is collected from the smart bin, in real-time, and transmitted, through the Internet, to an online platform where citizens can access and check the availability of the compartments scattered around a city
My Waste Bin prototype, which was able to efficiently collect and transmit information on residues deposited in its interior to In.Internet of Things (IoT), and, through the application My Waste App collecting information saved in the In.IoT, it was possible to have a perfect interaction with end users
According to the United Nations data, by 2050, approximately 70% of the population will live in urban centers, and this rapid growth of people living in cities has been of great concern, since towns do not always grow in a sustainable way
Summary
The latest developments in the Internet, with its underlying technologies, smart sensors and communication technologies, provide the possibility of connecting machines, devices, software, and objects communicating among them without human intervention, thereby paving the way for a new paradigm called the Internet of Things (IoT). The IoT can deliver significant savings, improve utilization of a city’s assets, increase process efficiency, and add productivity by directly linking low-cost technologies Some examples of these applications are smart cities, homes and offices, logistics and distribution systems, healthcare, surveillance and security, the supply chain, manufacturing industry, etc. Citizens of underdeveloped countries suffer most severely from the impact of unsustainably managed waste, In Brazil, for example, 80 thousand tons of solid waste are disposed of inadequately every day, according to the United Nations (UN) [9] In these countries, garbage is often disposed of inappropriately in rivers, streets or even in open incineration; these practices have severe consequences for human health, safety and the environment. The proposed system includes sensor technologies where waste information is collected from the smart bin (things), in real-time, and transmitted, through the Internet, to an online platform where citizens can access and check the availability of the compartments scattered around a city.
